HETEROPTERA IN THE VICINITY OF CRANBERRY LAKE 



By Cahl .1. Drake 



Family SCUTELLERIDAE 



Homaemus aeneifrons (Say) (Fig. 22, l>) 



Tliis insect is the most common species of the ScuteUeroidea 

 occuri-ing in the vicinity of Cranberry Lake. Nym])hs and adults 

 have been tak(m dui-ing 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 verj'- 

 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 scutellerid is quite variable in both 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 ap])earance. The size ranges from (5.5 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. Osboi'n collected a specimen while 

 sweeping in the Grasse River Bog.
