Mexico (E. Palmer). Mr. Burner 

 also sends me a specimen from Ft. 

 Grant, Arizona. 



Described from i $ , 2 9 . 



HlPPISCUS (X.) TIGRINUS Sp. llOV. 



Dark brownish fuscous, of robust form and 

 medium size. Head narrowed above and 

 rugulose; fastigium of vertex distinct with 

 rather sharp though not high bounding 

 walls, closed behind by a distinct but slight 

 transverse more or less arcuate and irregular 

 carina, the posterior half with a slight med- 

 ian carina which extends back more or less 

 distinctly over the head; lateral foveolae not 

 deeply impressed, triangular, the median 

 foveola between their tips slightly impressed : 

 frontal costa moderately broad, narrowed at 

 summit much more than below the ocellus, 

 deeply sulcate at the ocellus, plane at the 

 considerably expanding base. Pronotum ex- 

 panding considerably on the metazona, 

 which is centrally a little tumid, the rugosi- 

 ties of the latter, which are considerable, 

 ranged more or less distinctly into series 

 parallel to the sides of the process ; median 

 carina subobsolete or at least depressed be- 

 tween the sulci, distinctly arched on the 

 metazona; lateral canthi distinct and sharp 

 in the middle of the pronotum, a faint rather 

 broad ashen band next their inner side; pro- 

 cess rectangulate or less. Tegmina ashen 

 gray, brownish at base, vitreous on apical 

 third or more, the transverse bars dark 

 brownish fuscous, mostly crossing the wing, 

 those of apical half not at all rounded, with 

 rare exceptions with ill defined irregular 

 margins, and extending though fainter to 

 the tip of the wing; sutural line testaceous. 

 Wings very pallid citron at base, pellucid 

 at tip, occasionally with one or two fuligin- 

 ous cellular spots at tip, the veins and cross 

 veins blackish on apical portion, yellow on 

 basal, with a broad, subequal, arcuate, dark 

 fusco-fuliginous, median, scarcely tapering 

 band, leaving four or five lobes free, separat- 



ed by a yellow line from the humeral vitta 

 which extends from very nearly as far 

 out to the base of the wing, the costal mar- 

 gin fusco-testaceous. Hind femora external- 

 ly brownish fuscous with only obscure if any 

 darker very oblique bars, dirty clay yellow 

 below, the under surface, like the tibiae and 

 tarsi, luteous, the spines black tipped. 



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

 m m . 



The species is somewhat widely 

 spread, mostly at the eastern base of 

 the Rocky Mountains, extending from 

 Colorado? (collected by Lt. E. G. 

 Beckwith's party of Pacific R. R. ex- 

 ploration near Lat. 3S ) West Point, 

 Nebraska (Brunei-), and Nebraska 

 (Miss Walker) to Ft. Buchanan, south 

 of Tucson, Arizona (E. Palmer). A 

 specimen received from Mr. P. R. 

 Uhler has no designation of locality. 



Described from 5 9 > Dut the descrip- 

 tion is drawn up mainly from Mr. 

 Uhler's specimen, the • others having 

 been first immersed in alcohol. 



HlPPISCUS (X) LEPROSUS. 



Xanthijtipus lefirosus Sauss., Prodr. Oedip., 



I possess two poor 9, originally pre- 

 served in alcohol, both of which come 

 from much further north than de 

 Saussure's locality (New Mexico), one 

 of them collected by Dr. Suckley below 

 Lake Jessie at Ft. Benton, Montana, 

 during the N. Pacific R. R. surveys, 

 the other from Colorado (?) by Lt. E. 

 G. Beckwith on the Pacific R. R. sur- 

 veys about Lat. 3S . Mr. Brunei- also 

 sends me a specimen from Reno, Ne- 

 vada, collected by Hillman.
