 most of 4th, the extreme base of each succeeding article and the apex blackish, 

 head yellow, smooth, a distinct black spot enclosing ocelli and extending over back 

 of head; a spot in front and rear of mesothorax, a triangular spot on pleura, the 

 pectus and three apical segments of abdomen above, black; venter, four anterior 

 legs and posterior tarsi (in part) varying from yellow to pale rufous; four anterior

PANISCUS Grav. 

 Scape of antennae subovate, apex very obliquely truncated. Areolet triangular 

 externally, nervure broken. 



26. Paniscus geminatus. 



Ophion geminatus, Say, Macl. Lye. 1, 76.

There appears to be two distinct sizes of this, of which the largest av- 

 erages about 0.90 in length, 1.18 br. wings and the smallest, length 0.48, 

 br. wings 0.72 in., but I have not found sufficient difterence between 

 them to warrant calling them different species. 



27. Paniscus chloris. 



Ojohion cfiloris Oliv. Encyc. Method. Ins. 8, p. 509 (1811). 

 "Ophion pallide, testaceus, iramaeulatus, abdomine falcato, subtus dentate."

 There is very little doubt that this is the 0. geminatus of Say, from 



which it differs only in having two or three "dentelures" beneath the ab- 

 domen. Most of my specimens have thin transparent projections beneath 

 some of the segments, but they can hardly be called dentate or inclining 

 to it.
