 at tip, covering two joints; tibia as long as femur. Wings rather

Acanthaclisis hesperus n. sp. 



Similar to A. fallax Rbr. The pronotum shows a dark median 

 stripe, forked In front, lateral margins black, and between is a dark 

 stripe reaching to the transverse groove. Abdomen above dis- 

 tinctly striped with pale; male appendages yellowish; venter black. 

 Wings with many small spots by veins, dark spots between subcosta 

 ,and radius, but not between median and cubitus; hind wings without 

 marks; forks of axillary vein of fore wings connected by several 

 cross-veins. Larger than any A. fallax I have seen. From Eureka, 

 Utah, 15 July, and Jemez Mts., N. Mex., 28 July and 4 August 

 (Spaldings, Woodgate). Separated from A. fallax by black venter. 

 A. texana Hagen, I take to be A. fallax. I have this latter species 

 from Phoenix, Ariz., as well as Mexico. From A. americana these 

 forms may be separated thus: 



1. Forks of axillary vein in fore wings not connected by cross-veins; 



a spot in apical part of hind wings; dark between median and 

 cubital vein of fore \\dngs; male genitalia black; venter black, 



the abdomen not striped above americana. 



Forks of axillary vein of fore wings connected by one to three 

 cross-veins; no spot in hind wings; abdomen more or less 

 plainly striped with pale above; male appendag(5s mostly 

 yellowish : 2. 



2. Venter yellowish fallax. 



Venter black hesperus. 



Jlyrmeleon agriope n. sp. 



Very similar to M. crudelis Walk., but the vertex shows a trans- 

 verse row of four large pale spots, the submedian pair being longi- 

 tudinal, the lateral ones transverse and extending to the eyes; behind 

 -on the vertex are pale spaces in middle and on the sides. The 

 pronotum shows pale mark in middle of anterior part, the sides
