conical abdomen. The abdomen is ratlier shorter than elongate. I 

 notice that iScopolia sequax Will, is described as having the abdomen 

 ovate also. 



89. Scopolia sp. 



Colorado (Gillette) ; probably a new species. One specimen bred 

 from a leaf-roller on choke cherry. 



DEXIID^. 



90. IScotiptera n. sp. 



Southern Illinois (Robertson). One female I refer to this genus 

 on account of the very short stump at bend of fourth vein, and the 

 rather elongate proboscis. The third antennal joint is, however, not 

 more than twice the length of the second. The front of female is 

 narrower than the eyes at vertex, but in middle about as broad as 

 eyes. The cheeks are somewhat more than half the eye height ; the 

 bristles on the legs are rather stout. In other characters.it agrees 

 with V. d. Wulp's generic description in the Biol. .Cent.- Amer. Dipt. 



91. Clisetona n. sp. ? 



Colorado (Gillette). One specimen bred from Ecpuiitheria per- 

 macnlata. 



92. Tlielaira n. sp. 



Colorado (Gillette) ; one bred from Pyrrharctia Isabella. Probably 

 a new species. 



93. Tlielaira sp. ? 



Colorado (Gillette). One specimen, apparently of this genus, bred 

 from Ecpa)itheria pennacnluta. 



Another specimen of same genus as above, but of a different spe- 

 cies, bred from Pi/rrharctia imbella. 



MUSCID^. 



94. Orinia s]). ? 



A male and female specimen from Forbes, Illinois, seems to agree 

 with Onnia R. D., except in following points : Apical cross-vein is 

 not bowed out, but is actually bowed in. The face is strongly cari- 

 nate, which character is not mentioned by R. D. The male specimen 

 is indicated by P^orbes as bred from Cram bus sp. 



95. Coin-pswinyia inacellaria F. 



Illinois (Forbes) ; twelve specimens, four males and eight females, 

 three of them only 5-5.5 mm. Two of these three are females and 

 one is a male ; only one out of the twelve has the scutellum and 

 thorax posteriorly metallic-blue, the othei-s having these parts at most 

 deep metallic-green ; average length 7.5 mm. ; one measures 8.5 nun.
