B. tristis Stal. 



Berl. Ent. Zeit, vi, 309, 1862. 



More bluish or greenish black, with the dorsal carina of the 

 head scarcely paler. It has the same distribution as the preceding 

 and should be found in Connecticut. 



Brookfield, 27 July, E. L. Dickerson. 



Aphelonema Uhler. 



Short thick-set little insects with a square head and nearly ver- 

 tical front, marked on the sides of the head, thorax and abdomen 

 with pitted granules ; the front oval and truncated at base. 



Key to Species. 



Whitish, lineate with black ; front ovate histrionica 



Testaceous, nearly immaculate ; front nearly circular simplex 



A. histrionica (Stal). 



Berl. Ent. Zeit., vi, 310, 1862. 



Readily distinguished by two parallel dorsal lines and broader 

 lateral vittae on the abdomen; the sides of the face, pro- and 

 mesonotum are black with the carinae and granules pale. Massa- 

 chusetts westward and doubtless in Connecticut. 

 A. simplex Uhler. 



Bull. U. S. Geol. Geog. Surv. Terr., i, 356, 1876. 



Nearly uniformly soiled- or yellowish-testaceous. Recorded 

 from New Jersey westward. 



Plainville, 2 Sept., 1921 (B. H. W.). 



Tribe ISSINI. 



But one genus of this tribe has a distribution that would be likely 

 to bring it into Connecticut. 



Thionia Stal. 



Stout oblong insects with wings well developed ; elytra oblong 

 with strong veins, the front hardly longer than wide, sometimes 

 with three distinct discal carinae.

 veins 2 



2. Elytra brown, dotted with round fuscous points, the veins fuscous ; 



face with a pale band crossing the base of the clypeus elliptica 



Elytra more thickened and distinctly maculated, the marks usually 

 forming a transverse band before the middle ; disk of the front 

 distinctly tricarinate bullata
