Montana; Colorado (Snow); Las Cruces, New Mexico (Cockerell). 

 The 9 is very like costalis, but is smaller and has the last segment 

 yellow. If the $ of costalis, when discovered, presents no better 

 characters for distinction than those of the 9 , the two will probably 

 have to be united. 



16. Gorytes costalis Cress. 



Gorytes costalis Cresson, Tr. Am. Ent. Soc, IV, p. 225, J . 



Texas; Algonquin (Nason ) and Peoria, Illinois. A specimen from 

 St. Augustine, Florida (Johnson) has the legs entirely reddish 

 testaceous, only the two first segments margined with yellow and the 

 fuscous of the wings is much more extended than is usual. I am 

 indebted to Mr. Henshaw for the opportunity of examining the type 

 of this species.

Texas (Belfrage) ; Colorado; Dakota; Montana; Washington 

 State; Nevada; Los Angeles, California (Coquillett). This is a 

 variable species- both in size and coloration. The middle segment is 

 sometimes bispotted, and the legs may be yellow and black or the 

 femora may be more or less reddish. The spine of the ninth antennal 

 joint is much more distinct in some specimens than in others. 

 Length 7-9 mm. 



18. Gorytes microcephalus Hdl. 



Gorytes microcephalus Handlirsch, 1. c.,p. 405, $ . 



Georgia (Handlirsch) ; Colorado. I have taken it in the latter 

 part of June, in Camden County, New Jersey, but not commonly. 



19. Gorytes Pergandei Hdl.

Virginia and Illinois (Handlirsch). Unknown to me. The 

 middle segment is said to be more coarsely sculptured posteriorly 

 than in its allies, microcephalus and barbatulus, being " almost cica- 

 tricose. ' ' 



20. Gorytes nebulosus Pack. 



Gorytes nebulosus Packard, Proc. Ent. Soc, Phila., VI, p. 424, 9 . 



Massachusetts (Packard) ; New Jersey ; Georgia. The front in 

 this species is fully as broad as long, and the pygidium is broader 

 than usual.
