Habitat. Campus of the University of Colorado, Boulder, 

 Colo., July 25, 1908. ( T. D. A. Cockercll). 



The prothorax beneath has a sharp tooth at each lateral 

 angle. 



In Fox's Monograph on N. Am. Crabronidae this species runs 

 to insolens Fox (Colo.), but it differs from that species in the 

 following characters: Space between the hind ocelli not 

 greater than the distance to the nearest eye margin, if any- 

 thing slightly less ; there is a distinct impression extending to 

 the lower ocellus ; pronotum without a "strongly marked, trans- 

 verse impression on each side," crest of pronotum not highest 

 medially; larger size, etc. 



C. insolens Fox is the type of Dr. Ashmead's genus Epicros- 

 socerus. Dr. Ashmead apparently had not seen a 5 of insolens 

 as he only separated his genus, Epicrossocerus, from the males. 

 Fox's type of insolens is a 2 , and as far as I know no male 

 has been seen. 



If Epicrossocerus Ashm. is to be recognized as a subgenus or 

 section, and I think it may be separated from Crosso- 

 cerus Lep. and Brul. by the narrowed and excavated pygidium 

 of the 9 . The $ will probably be difficult to separate from the 

 males of Crossocerus. Epicrossocerus is nearer Blepharipus 

 Lep. and Brul. than it is to Crossocerus. It may be known 

 from Blepharipus by the keeled pronotum, dorsulum without 

 median depression, short abdomen, almost square head, and 

 containing species of a smaller size. 



DURING a brief stay in Thomasvillg this Christmas I was much sur- 

 prised on December 26th to meet with a single specimen of Hcliconius 

 charitonius, flying through the pine woods. A year before, at about 

 the same time, I met with Megathymus yuccae, flying about a portion 

 of the golf course. Both of these records were very unexpected, as a 

 few years ago I collected constantly for several seasons from November 

 to April without finding the least trace of either of these species. 

 Specimens of both species which I secured were so fresh that I can 

 hardly believe they had come from any considerable distance. This season 

 the fall weather had been particularly mild and many Endamus protcus, 

 Dione vanillae, Catopsilia eubule and other distinctly warm weather 

 species were on the wing, and usually in good condition. MORGAN
