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

 occipital spots in rcsolntum 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 resolution ; in hastulatum the lat- 

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

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

 entirely pale yellow ; in hastulatum 9 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 resolu turn the lower branch 

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

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

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

 concealed behind the inferior appendages. The inferior ap- 

 pendages of resolutum J> are much smaller than those of hastul- 

 atum 1 not concealing the lower branch of the upper append- 

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

 in hastidatuni $ 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- 

 tulatnm , a small pale streak on each side of the dorsal black of 

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

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

 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.
