Psyllia carpinicola (Crawford). 



The species occurs iii great abundance and a great vai'iety of 

 trees, but was especially plentiful as adults on yellow birch, white 

 pine and fire cherry. Barber Point and Cranberry Lake, July 8, 

 14 and 28, 1919 ; July 8-25, 1920. 



Psyllia floccosa Patch. 



Cranberry Lake, Barber Point, Plains, Childwold and Ranger 

 School in abundance on alder. Agrees with description of floccosa, 

 especially in genitalia. No nymphs with flocculent covering seen 

 on alder at camp, but these may have matured before my arrival. 

 The Ranger School specimens were taken in alder clump on rocky 

 hillside which was very moist during July and August, 1920. 



Psyllia 3=maculata Crawford (Figs. 42 and 43). 



A very abundant form on great variety of plants in adult stage. 

 Nymphs, the flocculent form, are very abundant on Frunus 

 pennsylvanica. The adults have more or less varying shades of 

 yellow to red on thorax {frhnacidata — see life history notes). 



HETEROPTERA IN THE VICINITY OF CRANBERRY LAKE 



By Carl J. Drake 



Family SCVTELLERIDAE 



Homaemus aeneifrons (Say) (Pig. 22, h) 



This insect is the most common species of the ScuteUeroidea 

 occurring in the vicinity of Cranberry Lake. Nymphs and adults 

 have been taken during June, July, August and September, but 

 most of the immature forms attain the adult state before Sep- 

 tember. The species is quite generally distributed, but it is by far 

 more abundant in the neighborhood of low marshy meadows and 

 swamps. Van Duzee (?. c, p. 548) states that the insect is ver}^ 

 generally distributed and common in the Adirondacks where there 

 were low, marshy spots with carices intermixed with swampy 

 grasses. He took an adult upon a species of Scripus on the sum- 

 mit of Cobble Hill. 



This scuteilerid is quite variable in ])oth size and color. The 

 color varies from pale yellow or dull to quite dark or blackish 

 forms. The dull or glossy or pale color-forms are often more or 

 less variegated with fuscous or black, thus giving the insect a 

 marbled appearance. The size ranges from 6.5 mm. to 9.5 mm. 

 in length. 



Eurygaster alternatus (Say). 



Four specimens, taken at Wanakena and Barber Point near a 

 grassy bog in an old burn. Osborn collected a specimen while 

 sweeping in the Grasse River Bog.
