 would never have been discovered but for their .song. But even wIkmi 

 once discovered their capture was not at all assured, for liicv blended 

 in color with the tvniss so perfectly and were so active in chidiiiu- the 

 grasp that many would escape when almost in the bottle.

Six males, three females, Fort Collins, August 19; live males and 

 three females, Williams, Arizona, from June 6 to July 80, and one 

 male at Flagstatf. Arizona, on July 4. The specimens from Wil- 

 liams were found under bark, quite a surprising fact considering the 

 hal)itat of the type specimens. In the more immature specimens the 

 lateral lo])es are persistently striped wnth a longitudinal ])lackish stripe 

 which extends across the thorax and nearl}- to the end of the abdomen. 

 On the thorax the stripe is sharph' defined above and fades out gradu- 

 ally below. At Williams they appear to mature aliout a month earlier 

 than at Fort Collins, the mature specimens being taken at the former 

 place on July 1. The mature individuals from Arizona have the pos- 

 terior femora marked externally by two ])lack stripes, as mentioned 

 under the next species.

One female from Hot Springs, Arizona June 12. This specimen is 

 somewhat larger than the type and the pronotum is somewhat infus- 

 cated, the infuscation confined to a little more than the anterior half 

 and not reaching to the inferior margins of the lateral lobes, though 

 there is a dash of black next the margin just above the sinus. The 

 posterior femora have two longitudinal black streaks, converging 

 somewhat posteriorally. The nuMisurements ai"e as follows: 



Length of thorax, 8.5 mm.: fore femora. '.» iniu.: hind feuioia, i^tl 

 nun. : ovipositor, 19 mm.
