366 NEW NORTH AMERICAN MELANOPLI (oRTHOPTERA) 



mummy brown. Caudal femora drab externally, with proximal and genicu- 

 lar blotches and two intervening bars of darker brown very weakly defined; 

 internal fate dorsad with the corresponding darker areas more decided, 

 blackish mummy brown, below and particularly in proximal portion bright 

 ox blood red, often shading toward carmine. Caudal tibiae hair brown, 

 shading to ox-blood red in distal half, this brilliant on flexor surface but 

 merely tinging the extensor surface, external spines black, internal spines 

 and all spurs buffy, black tipped. 



In the series the general grayish coloration shows a more brownish tinge 

 in individual specimens, the darker streaking and dotting showing little 

 variation in intensity. The females have the dark and paler markings of 

 the caudal femora averaging more decided than in the males. In these the 

 pale areas are composed of an irregular proximal section, beyond this a mark- 

 ing like a short feathered shaft of an arrow meso-proximad, a large meso- 

 distal section with margin produced proximad in a V and an irregular pre- 

 genicular band, these areas individually ranging from pinkish buff to clay 

 color. 



Specimens Examined: 8; 2 males and 6 females.

Scudder, 1875), Proc. Davenport Acad. Sci., ix, p. 50. [Organ Mountains,

Tliis insect is a member of the Ponderosus Group, showing 

 nearest relationship to 'ponderosus (Scudder) (plate XVIII, fig. 

 2) and supplanting that species westward of the Pecos River in 

 Texas. 



The major difference between these species is found in the male 

 cerci, though a normal specimen of eumera appears to be very 

 strikingly and differently marked and colored from a normal 

 specimen of poiukrosus. On closer examination, however, these 

 latter differences are seen to be the result of an intensification 

 and consolidation of the color pattern in eumera, showing less 

 actually diagnostic differentiation than might at first be presumed, 

 and the convergence of the color ])attern l^etwcen recessivcly
