 the antennns (four terminal joints) and disk of the pectus black.

I have not seen this species, but presume it belongs in this section.

 the antenna white. Inhabits Indiana. Length rather less than half 

 an inch." 



Three specimens from New England are larger. (Long, about 0.60, 

 Ex. alar. 1.05 to 1.10 in.) Antenna? stout, serrate beneath, wing 

 scale, scutellum and tip of basal membrane, white (in one case the 

 scuteUum is black) ; coxae all black ; trochanters, base of femora, and 

 tarsi white ; tibia? and two thirds of basal joints of posterior tarsi 

 black ; head roughened ; thorax smooth above ; pleura coarsely 

 punctured. 



&. Second recurrent nervure received near middle of second sub- 

 marginal cell ; body short. 



8. E. MACULATUS, (n. sp.) Black ; an interrupted brownish band 

 on each segment of abdomen. (Long. 0.20 to 0.22, Ex. alar. 0.42 to 

 0.47 in.) 



? . Black ; antennae short and slender, third joint longer than 

 fourth, flagellum sometimes ferruginous beneath ; cl}'peus wide, pro- 

 duced, somewhat crenate ; labrum retracted ; clypeus, labrum, and 

 palpi dull white ; head and pleura sericeous ; body smooth and shin- 

 ing ; wing scale, edge of collar, and a spot on first segment of abdo- 

 men, white ; a brownish interrupted band on each following segment ; 

 legs varying from white to pale-brown ; four anterior femora beneath ; 

 apical joints of tarsi above, and all the coxae, except at tip, black ; 

 posterior femora, tibias at tip and the tarsi, except base of first joint, 

 black ; wings hyaline ; stigma beneath brownish black, base pale. 



$ . The male differs only in having the antennae brown beneath ; 

 the interrupted bands of abdomen dull white, and the legs varying 

 from white to reddish-brown ; coxas and posterior femora (above 

 only) black. Hab. Farmington, Conn. 



Eight specimens examined. This resembles Blennocampa fenusa, 

 Europe. 



9. E. EECEXS. Say. B. Jour. 1, 221. "(5. Antennae, basal joint 

 white ; pectus and feet white. Length one fifth of an inch."

10. E. PLATYCERUS. Say. B. Jour. 1 , 221. $ . Black ; tibiae and 

 tarsi white ; first and second joints of the antennae short, equal. 

 Length less than three twentieths of an inch. I have but one speci- 

 men, a female, and do not feel quite sure that it is the same, as the 

 first joint of the antennse is a little longer than the second.
