PSYCHE. 



349 



sides with cinereous carinae; spines black 

 tipped. 



Length of body, 37 mm.; of tegmina, 25 

 m m . 



Described from i 9 m the collection 

 of Mr. Lawrence Brunei", taken on the 

 Pinal Mountains of Arizona. It is ap- 

 parently an alpine form. 



Hippiscus (X.) pumilus sp. nov. 



Very dark brown with generally slight cin- 

 ereous shades, of rather a slender form (the J 

 more robust) and of a small size. Head 

 tolerably tumid and moderately broad above, 

 very variable in abundance and prominence 

 of rugosities, but which are never very pro- 

 nounced: darkest above, the face and cheeks 

 often pallid cinereous flecked with fuscous, 

 sometimes collected into short oblique 

 stripes on the posterior part of the head ; 

 vertex offastigium distinct and plane with 

 sharp but low bounding walls, broader in $? 

 than in $ where it is usually longer than 

 broad, rarely closed behind, the lateral walls 

 usually regularly arcuate with a slight ten- 

 dency to a median angle; median carina 

 generally terminating in the middle of the 

 fastigium ; lateral foveolae subtriangular, con- 

 siderably longer than broad, rather shallow; 

 median foveola variable, sometimes obsolete, 

 sometimes biareolate and distinct from verti" 

 cal fastigium only by being at a lower level ; 

 frontal costa moderately narrow, narrowed 

 at summit, sulcate, sometimes through its 

 whole extent and then continuous with and 

 suppressing the median foveola, sometimes 

 not affecting the summit, the lower portion 

 expanding more or less and finally obsolete. 

 Antennae shorter than ( °. ), or more than half 

 as long again as (J) the head and prothorax 

 together, luteo-fuscous at base, blackish 

 fuscous beyond, distinctly tapering only in 

 the last three or four joints in the $ , in at 

 least the latter fifth and cochleate in the $ . 



Prothorax compressed and expanding very 

 slightly in the $ , robust and expanding con- 

 siderably in the $, the prozona subtectiform, 

 the metazona plane and in the $ a little 

 tumid centrally, with scattered slight, short, 

 linear verrucosities inclined in various direc- 

 tions and besides but few granulations; a 

 broad bent pallid or cinereous band on either 

 side, often obsolete; median carina slight 

 and equal ; lateral carinae distinct and rather 

 sharp but not prominent; upper portion of 

 lateral lobes of prozona black or blackish 

 with a superior oblique pallid dash and a 

 median posterior quadrate pallid spot. Teg- 

 mina blackish brown with pale cinereous 

 markings often almost wholly obliterated 

 except some slight spots and streaks along 

 the costal margin and a narrow transverse 

 stripe crossing the base of the outer discoidal 

 area; generally also with a triangular patch 

 depending from the costal margin and ex- 

 tending, sometimes interrupted, across the 

 middle of the inner discoidal area, with an- 

 other slender stripe midway between this and 

 the outer stripe and connected with the latter 

 by a stripe following the base of the anterior 

 ulnar nervule; but sometimes increased in 

 extent- and in number by multiplication of 

 other, sometimes sinuous, transverse stripes, 

 especially in the apical half and in the upper 

 portion of the extreme base so that the 

 ground is about equally divided between the 

 two colors and the markings assume some- 

 what the distribution which prevails in H. 

 (A^.) afflictus; there is a broad conspicuous 

 bright flavous sutural stripe and the brown 

 axillary field is usually immaculate. Wings 

 very pale citron or salmon red at base with 

 corresponding reticulation, vitreous apically, 

 the extreme apex sometimes maculate, with 

 black reticulation and a fuliginous median 

 arcuate band, which is generally fainter and 

 narrower in the $ than in the $ , where it is 

 sometimes blackish fuliginous, and varies 

 from a width hardly equal to more than one 

 of the interspaces (when it may escape the 

 border altogether) to a broad band more
