No. 34-] HEMIPTERA OF CONNECTICUT: LYGAEIDAE. 719 



Hypogeocoris Montandon. 

 (Isthmocoris McAtee.) 



H. piceus (Say). 



Het. New Harm., 18, 1832. 



Only this one species of the genus occurs in the northern states. 

 The head is extra wide, the eyes set upon short, broad stalks. Its 

 color is very shining piceous, with the head above and below, base 

 of first antennal segment, legs and acetabulae ochraceous. The 

 surface, except the head, sparsely but coarsely punctate. In 

 brachypterous forms at least, the clavus is not plainly differen- 

 tiated and is level with the corium. I have never seen any 

 specimen with the membrane fully developed.

Geocoris Fallen. 



Only two species of this genus occur in New England but each 

 is subject to considerable color variation and a number of these 

 forms have been named and described. 

 G. bullatus (Say). 



Het. New Harm., 18, 1832. 



In this species the scutellum is plainly longer than wide, gener- 

 ally piceous in color with an enlarged yellowish, punctate area on 

 each side. The corium is generally griseous, with fuscous mark- 

 ings along posterior margin. Brachypterous form unknown to 

 me. 



G. discopterus Stal, is made a variety of this species by McAtee, 

 1 91 4. It is a smaller, more profusely punctate form and as it 

 occurs in both macropterous and brachypterous conditions I have 

 considerable doubt of McAtee's conclusions.

G. bullatus var. discopterus Stal. 



Enum. Hemip., iv, 136, 1874.

 (B. H. W.). 



G. uliginosus (Say). 



Het. New Harm., 19, 1832. 



This in all of its color variations can be distinguished from 

 bullatus by the scutellum forming an equilateral triangle; this 

 part colored uniformly piceous, without the yellowish or griseous 

 area on each side. Most commonly the corium is more or less 

 widely pale margined, with the inner surface piceous. The four 

 color varieties differentiated by McAtee, 19 14, can usually be 

 distinguished by his key, as follows :
