ORTHOPTERA—ACRIDIDAE— OEDIPODA NEGLECTA. 881 



tipped with black. The portions described as fuscous are in fact pale fus- 

 cous-brown. Antennae slender. 



? . — Length, 1.9 inches; elytra, 1.5 inches; posterior femora, 0.85 

 inch. 



This fine, large species forms an interesting link between GE. trifasciata 

 and (E. corallipes, and with my (E. montana well nigh fills up the hiatus. 

 It agrees in every respect with Stal's genus Pycnodictya, except that in that 

 genus the posterior lobe of the pronotum is much longer than the anterior, 

 while in this species the two are nearly equal. He gives as the type of 

 this genus the Gryllus obscurus of Linne", with (E. rosacea of Serville as a 

 synonym. Serville (Hist. Orthop., 728-729) describes the two as distinct 

 species; and as his (E. rosacea has "a slightly elevated carina" on the pro- 

 notum, it appears difficult to reconcile this with Stal's diagnosis. As he had 

 access to Linnseus's type, this was most assuredly his guide in forming his 

 genus; and Serville's description accords very closely with the generic 

 characters so far as he gives them. The wings of these species are red at 

 base, and possibly this was the original color in the species before me, but 

 I think it was yellow. 



Named in honor of Lieut. G. M. Wheeler, in charge of the expedition. 



This species is placed in CEdipoda provisionally, as it must be removed 

 when this genus is restricted to its proj>er limits. I am strongly inclined to 

 name it at once Pycnodictya Wheeler ii; otherwise a new genus will have to 

 be formed for its reception.

I find in the collection a specimen which probably belongs to this 

 species; but the head and thorax are so badly damaged that it is impossible 

 to determine this with any degree of certainty.

I find one specimen of this species in the collection of 1873, probably 



from Southern Colorado. I found it quite common in Northern Utah and
