{Continued from page Jj6). 



This species so far as known is con- 

 fined to the northern half of the United 

 States in the general vicinity of the 

 Rocky Mountains. Specimens before 

 me come from the upper Missouri and 

 Yellowstone (F. V. Hayden), explora- 

 tions in Dakota under Gen. Sully (S. 

 M. Rothhammer) , Nevada (H. Ed- 

 wards), Utah (P. R. Uhler), about 

 Rangeley on the lower White River, 

 western Colorado (S. H. Scudder), 

 Colorado, 5500', probably at the eastern 

 edge of the foot-hills (H. K. Morrison, 

 in S. Henshaw's coll. and my own), 

 and Yuma, Arizona, collected by Wick- 

 ham (Bruner). 



I have seen but two specimens with 

 red hind wings, both females from 

 Rangeley, Colorado. 



HlPPlSCUS (X.) TOLTECUS. 



Xanthippus toltecus Sauss., Prodr. Oedip., 

 91-92. 



If I have correctly identified Saus- 

 sure's species it has a wide range. He 

 records it from Mexico alta. I have 

 seen specimens from Spring Lake Villa, 

 Utah Co., Utah, Aug. 1-4 (E. Palmer), 

 Helena, Montana. June 21 (A. S. 

 Packard), and Laramie River, Wyom- 

 ing, (L. Bruner.) 



HlPPlSCUS (X.) ALTIVOLUS Sp. IIOV. 



Dark obscure brownish fuscous, not very 

 robust and of small size. Head dull dirty 

 cinereous with numerous more or less clus- 

 tered blackish points, most abundant above; 



summit relatively broad, scarcely at all tumid, 

 subrugulose, the vertical fastigium indistinct 

 from the low and dull bounding walls, 

 closed behind by the arcuate incurving of 

 the lateral walls, separated distinctly from 

 the tolerably deep, biareolate median foveola ; 

 lateral foveolae rather small, triangular, 

 subequiangular; frontal costa of moderate 

 breadth, fading and not expanding below, 

 but little contracted at summit, broadly and 

 shallowly sulcate throughout. Prothorax 

 but slightly expanding on the metazona, 

 the dorsal area plane, scarcely indentate 

 at the front margin of the metazona, 

 sparsely verrucose and in addition abun- 

 dantly but bluntly and obscurely arenaceous; 

 process rectangulate ; median carina low, 

 subequal, not arched ; lateral carinae tolera- 

 bly pronounced; lateral lobes bluntly subru- 

 gulose on the metazona, marked with a large 

 subquadrate blackish spot on the prozona. 

 Tegmina very short, extending when at rest 

 but little beyond the hind femora, dirty cin- 

 ereous with obscure dark brownish fuscous 

 transverse more or less blended bands, 

 broader than the intermediate ashen ground, 

 and therefore occupying much the larger 

 space even on the apical half which is 

 scarcely at all vitreous ; sutural stripe obscure 

 testaceous. Wings pale dull citron at base 

 with similar reticulation, sub vitreous apically 

 with black reticulation and between a strongly 

 arcuate, moderately narrow, blackish fulig- 

 inous band which narrows in passing toward 

 the anal angle, which it fails to reach, and 

 does not narrow above ; it lies entirely in the 

 apical half of the wing, leaves four marginal 

 lobes free, and appears not to be at all sepa- 

 rated from the humeral vitta whose outer 

 limit is in oblique continuation of its outer 

 curve and which reaches almost to the base; 

 the basal half of the costal margin is testa- 

 ceous. Hind femora brownish cinereous 

 externally, with rather obscure oblique 

 brownish stripes, the inferior surface dull 

 coral red like the tibiae which are more or
