valuable, judging from the material before me. The post- 

 occipital spots in resohitum may be dentate, deeply crenate, or 

 entire behind. Only rarely the lateral spot on abdominal seg- 

 ment 2 of the male is separated from the dorsal spot and then 

 only by a mere line of blue in resoluhun ; in hashilatuni the lat- 

 eral spot is variable in size, but is well separated from the dorsal 

 spot in any case. In resoluhun $ 9 the rear of the head is 

 entirely pale yellow ; in hastulatuni S $ the region about the 

 foramen is black, and this may extend very nearly to the eyes. 

 I can detect little if any difference in the color of the ptero- 

 stigma. The abdominal appendages of the males, on the other 

 hand, offer clear differences. In rcsolutum %, the lower branch 

 of the superiors is slenderer, as long as the inferiors, and with 

 a distinct knob at the end ; in hastulahim $ the lower branch 

 is shorter, heavier, only slightly enlarged at end, and largely 

 concealed behind the inferior appendages. The inferior ap- 

 pendages of 7'esolutuni % are much smaller than those of hastul- 

 atuni % not concealing the lower branch of the vipper append- 

 ages, apex distinctly bifid, the two branches equal in length , 

 in hastulatum $ not so distinctly bifid, the upper branch the 

 longer. [The hind margin of the prothorax is rounded in both 

 sexes of resolutum, angulate in the middle in both sexes of has- 

 tulatum ; a small pale .streak on each side of the dorsal black of 

 the prothorax of rcsolutum is absent in hastulatum. I take ad- 

 vantage of this opportunity to add a new locality for resohitum, 

 viz. : Volga, South Dakota, whence I have a male taken June 

 26, 1889, and sent me by the late Judge P. C. Truman. — P. P.
