PSYCHE. 



[ July, 1S92. 



very narrow yellow line from the humeral 

 stripe which runs two-thirds of the way to 

 the base traversed interiorly by conspicuous 

 yellow cross veins ; costal margin more or 

 less tinged with orange, the apical portion of 

 axillary area with a few cellular fuliginous 

 spots clustered along the veins. Hind fe- 

 mora uniform coral red within from base to 

 apex, testaceous externally with clouded fus- 

 cous oblique stripes, above mostly fuscous; 

 hind tibiae coral red externally, pallid toward 

 base, the spines black tipped. 

 Length of body, 39 mm. ; of tegmina, 37 mm.

This species not only shows a depart- 

 ure toward the Xanthippus type of 

 structure of the pronotal carina, but it 

 strikingly resembles H. (X.) con- 

 spicuus Scudd. It differs from the lat- 

 ter, however, in the structure of the 

 head and pronotum, as well as in the 

 width of the arcuate dark band of the 

 wing ; and from the Xanthippus type 

 generally in the great depth of the infer- 

 ior carina of the hind femora. So far 

 as can be seen the antennae are of the 

 Hippiscus type, but the tip is lost in 

 the only specimen known.

I have re-examined some of the types 

 of this species and base thereupon my 

 conclusions about the synonymy of this 

 and the allied species. That it is 

 the H. namis of Saussure there can, I 

 think, be no question. It is not the Oe. 

 paradoxa of Thomas, which an exami- 

 nation of the type shows to be a Xan- 

 thippus, though Glover figures quite 

 a different insect. Illinois specimens 

 labelled by Thomas show, strange as it 

 may seem, that it was this insect which 

 he mistook for his Oe. neglecta. 



This species appears to be confined 

 to the centre of the continent. Passing 

 from east westward, the localities known 

 to me are the following : Moline, 111. 

 (McNeill), southern Illinois (Thomas), 

 the Red River of the North (Kennicott) , 

 middle Kansas (Bruner in litt.), all 

 eastern and middle Nebraska and the 

 Sand Hills of the same state (Bruner in 

 litt.), eastern Nebraska (Dodge), Ne- 

 braska City and the banks of the Platte 

 River (Hayden), Garden of the Gods, 

 Colorado (Packard), Colorado (Saus- 

 sure) . 



Hippiscus (H.) texanus sp. nov. 



Brownish fuscous, darker above than on 

 the sides, inconspicuously dotted with black, 

 the head, excepting above, ochraceous more 

 or less mottled with brown, the vertex behind 

 scutellum lightly corrugate, often in the 

 $ transversely disposed ; scutellum large 

 with slight and not sharp bounding walls, of 

 nearly equal length and breadth ( $ ) or much 

 longer than broad {$), its front margin 

 deeply V-shaped and connected more or less 

 faintly at the point of the V with the longi-
