shaped black marks down the top of the abdomen and a row of oblique 

 black dashes along the sides (fig. 88). The lateral lobes of the pronotum 

 are generally bordered below and behind with yellowish, and next 

 this 3'ellow border behind is usually a piceous streak.

 female, 5-1; ovipositor, 16-24; width, pronotum at posterior margin,

Type. — Apparent!}^ lost. 



Specimens examhied. — Material from Nebraska, (Colorado, Montana, 

 and Idaho. 



The National Museum contains specimens labeled as types, but 

 erroneously so, as the species was de.scribed from southeast Colorado, 

 while these specimens 

 are froui South Pass, 

 Wyoming; but they arc 

 doubtlessly authentic 

 specimens, being la- 

 beled in the handwrit- 

 ing of Thomas. Be- 

 sides these, the National 

 Museum contains speci- 

 mens, all females, from 

 Nebraska, Colorado, 

 Montana, and Idaho. 

 Besides these localities 

 the species has been 

 recorded from Utah, 

 Wyoming, and New 

 Mexico. 



The figure by Glover is not a good one, failing, as it does, to properly 

 show the thoracic carinae. 



Besides the statement that the pronotum is without carintp the 

 original description contains some other minor points at variance with 

 the characters of the specimens now considered as this species. But, 

 as stated in the discussion under the genus, Herman's construction is 

 accepted. 



There is an immense amount of variation in color and general 

 appearance of the specimens here referred to this species. Some 

 specimens are light, with conspicuous abdominal markings and with 

 short legs and ovipositoi's, as shown in fig. 88, and others are very 

 uniformly brownish or greenish yellow, with long posterior femora 

 and ovipositors, while still others have the conspicuous abdominal 

 markings, but with long posterior femora and ovipositors. The cerci of 

 the males sometimes have the tooth situated at the middle (fig. 91),
