[Dallas, Texas.] 



This species averages larger and has the ovipositor averaging 

 longer than in an}'' other species found in the United States. 

 Though differing very decidedly from C. nemoralis and occiden- 

 talis, the present insect shows unquestionably an extreme devel- 

 opment from a common ancestor with these species. 



In coloration the dorsum of the abdomen, the cerci and the 

 ovipositor are dark brown, the remaining portions of the insect 

 are green excepting the usual medio-dorsal dark stripe on the head 

 and pronotum which is narrowly bordered with buff, in the females 

 these narrow dorso-lateral buff lines are continued on the abdo- 

 men to the base of the ovipositor. Material from the arid south- 

 west usually shows a decidedly paler type of coloration in which 

 the dorsum of the abdomen is often very weakly infuscated or 

 greenish yellow; frequently in pale females from this region the 

 color pattern described alcove is strongly defined, the abdomen 

 showing a very broad medio-dorsal fuscous band bordered by a 

 narrow buffy band on each side, the sides of the abdomen below 

 this infuscated, this coloration heaviest dorsad along the bor- 

 ders of the pale dorso-lateral bands, thus making them very pro- 

 nounced.

 urements; length of body 16.6, of tegmen 4.2, of caudal femur 16.4, of ovi-
