REHX AND HEBARD 63 



show an infuscation of the external face of variable position 

 and depth — this, however, may be absent. Generally this infus- 

 cation is ventral and rather solid, again it may be along the 

 median hne and narrow or wholly broken up into scattered 

 marmorations. This latter condition is more pronounced in 

 the male than in the female sex and apparently is purely indi- 

 vidual. The ovipositor varies in color with the general tone. 

 The entire ventral surface of the thorax and abdomen is bright 

 yellow in the living specimens we have seen. 



In this species the pale ochraceous of the disto-dorsal portion of 

 the male tegmina is just as marked as in testaceus and pachymerus, 

 and perfectly constant in the males seen. The pale border of 

 the humeral sinus of the lateral lobes is equally constant in 

 presence, but varies some in length and also in contrast, the 

 latter largely due to the depth of the blackish of the adjacent 

 portion of the lateral lobes. The latter feature is as variable 

 as in the other species of the genus. One male from Arlington 

 is most strikingly colored, reminding one of certain individuals 

 of the Acridids, Hippiscus phoenicopterus and Scirtetica marmo- 

 rata, as it has the entire dorsal surface of the head, pronotal 

 disk and abdomen, except for a narrow median bar of the general 

 brown color, of a uniform Rinnemann's green (Ridgway).
