PENTATOMIDAE Sciocoris microphthalmus Flor.
Eight specimens, taken during July and August while sweep ing grasses and rank weeds at Barber Point and \Vanakena. f have very carefully collated the specimens with a male and female in the late Puton's collection (from Paris Museum) and find the American specimens identical with European examples determined by the late Puton. This seems to be the only record for New York State. The insect has been recorded for Ontario, New Hampshire. Maine, Michigan and Minnesota.
Peribalus limbolarius Stal.
One example, collected at the Plains, July, 1920.
Crataegus Hill at Barber Point and Plains during August; 1920. This is not a common species in the vicinity of Cranberry Lake.
Common: Barber Point, Wanakena and the Plains during July, August, and September, 1917, 1919, and 1920. Numerous specimens were observed breeding and feeding on mullein, erbascum Thapsas Linn. at the Forestry Camp. Many examples were also collected while sweeping various herbaceous plants.
Barber Point, Wanakena, Plains and Conifer. This insect seems to be a general feeder upon many herbaceous plants and sometimes on birch, beech and poplar trees. It hibernates in the adult state. The eggs are frequently parasitized by a small hymenopterous parasite.
This is the most common pentatomid in the vicinity of Cran berry Lake and is found during the entire summer. It is a gen eral feeder upon herl.)aeeous plants and also frequently breeds on trees (white and yellow birch, ironwood, poplar, beech and maple). Adults and nymphs have also been collected on the blossoms of wild spiraea (Spiraea lalifolia Borkh.). Several adults were taken bearing tachinid eggs, but the parasite failed to develop in the laboratory. Hymenopterous parasites have reared from its eggs.
Wanakena and Barber Point, Ffnly and August, 1919 and 1920. Not common.
One adult and several large nymphs were collected while sweep ing grasses and weeds in a semi-marshy place near a small stream in the Plains during the last week of July, 1920.
Common: Barber Point, Wanakena. Conifer and the Plains during June, July and August, 1920. It is found on herbaeeous plants.
Common on weeds and rank vegetation. Adults and nymphs were noted at various times during the summer feeding on mullein; Thyanta custator (Fabrieius).
An adult and several nymphs were collected at the Plains, Crataegus Hill and Barber Point, 1920.
Banasa dimidiata (Say).
Very common: Barber Point, AVanakena, Plains, Crataegus Hill, and Conifer. Adults and nymphs have been found on yellow
birch, beech and also on various herbaceous plants. The eggs are frequently parasitized by a small hymenopterons parasite.
Meadorus lateralis (Say) (Fig. 23, I)), This is largely a tree-inhabiting species. Specimens have been observed depositing eggs on yellow- birch and beech at. Barber Point during June, July. and August. The winter is spent in the adult state. )Iy records indicate two generations a year dur ing the summers of 1919 and 1920.
Nymphs and adults were taken in the tops of large yellow birch trees (felled for catkins while studying the insects affecting re production of yellow- birch) in the vicinity of Barber Point during July, August and September, 1920. by Mr. Erie Johnson and the writer. In some very tall trees many nymphs, representing three or fora' instal's, and adults were feeding on the leaves and eatkins. Adults were also reared from eggs and nymphs (taken from the tree tops) on catkins placed in glass breeding cages in the in sectary. 31. lateralis, although sometimes taken while sweeping herbaceous plants, is primarily a tree-inhabiting species. It also breeds on white birch and beech trees.
Elasmotethus cruciatus (Say).
Barber Point and Wanakena, August, 1917, 1919, and 1920.
Flasmostethus atricornis (Van Duzee). Barber Point. August, 1920.
Mineus strigipes (lierrich-Schaeffer).
Four examples, collected at Barber Point, July 19 and 26, 1920, and one specimen at Wanakena, August 1, 1917.
circumcinctus Stal.
Two examples, Wanakena, July :10, 1917. and two specimens at Barber Point, August, 1920.
Perillus exaptus Say, var. d Van Duzee.
A single specimen of this variety was taken while sweeping rank vegetation near a small stream in a semi-aquatic place in the Plains, August, 1920. Van Duzee lists var. d. from Colorado and Washington. The typical form is a widely distributed species, extending from Vancouver to Quebec and southward to Colorado, New Mexico and New Jersey (fide Van Duzee).
Podisus serieventris 17hler.
Abundant : Barber Point, Plains, Wanakena, Island, Buck Island and Conifer, June, July, August and September, 1917, 1919 and 1920.

Podisus placidus Uhler.
Several specimens: Barber Point. Plains and Wanakena, June, July and August, 1917, 1919 and 1920.
Podisus maculiventris (Say).
Barber Point and Wanakena, 1917, 1919 and 1920. Osborn found a specimen on yellow birch feeding upon a frog-hopper, Clastoptera obtusa (Say) and the writer took a specimen on a willow tree with its beak impaled in a. lampyrid beetle.
