ally vitreous) with strongly contrasting pale 

 cinerous and blackish fuscous markings, 

 with sharply defined margins, deepest in 

 color in the marginal field, distributed much 

 as in H. (X.) corallipes. Wings very pale 

 clear citron yellow at base, apically vitreous 

 with black longitudinal veins, the cross veins 

 brown often inclining to yellow; and between 

 the two a very narrow, arcuate, fuliginous or 

 brownish fuscous band scarcely broader tban 

 the width of the interspaces, deepest in color 

 at and beside the cross nervules, and sepa- 

 rated by a citron line fi om the humeral vitta 

 which reaches outwaul only to the inner 

 margin of the arcuate band and inward half 

 or three quarters way to the base; costal 

 margin narrowly b ownish yellow; outer 

 margin free from the arcuate stripe for fully 

 half its length. Hind femora pale cinereous 

 obscurely marked with exceedingly oblique 

 dusky stripes, beneath blood red, immaculate ; 

 hind tibiae coral red", hoary or pallid without, 

 the spines black tipped.

The species comes from Kansas (P.

 City, L. Brunei") .

HlPPISCUS (X.) FREMITUS Sp. HOV. 



Similar to the preceding, but with much 

 more broken markings on the tegmina. The 

 single specimen having been preserved in al- 

 cohol, the colors of the head and thorax are 

 uncertain (and the inequalities of the sur- 

 face of the head intensified), but it appears to 

 be of a rather dark grayish fuscous strongly 

 marked with cinerous, especially in a stripe 

 which follows the lateral carinae of the pro- 

 thorax and extends to the eye. Summit of 

 head transversely rugulose, with a median 

 carina extending to the middle of the fastig- 

 ium of the vertex which is of about equal 



breadth and length with rather high angulate 

 bounding walls, indistinct posteriorly and 

 open in front to the small, partially biareo- 

 late, rather deep and small frontal foveola 

 which lies between the tips of the moderate- 

 ly large and distinct triangular lateral foveo- 

 lae, whose upper walls are arcuate; frontal 

 costa deeply sulcate, much narrowed above, 

 fading below. Pronotum arenaceous and 

 rather sparsely and feebly venuculose, the 

 metazona not deeply impressed anteriorly, 

 a little tumid, with distinct but not high and 

 equal lateral carinae ; metazona twice as long 

 as prozona; process of metazona slightly less 

 than rectangulate : median carina moderately 

 high, almost obliterated between the princi- 

 pal sulci, arched on the metazona. Elytra 

 maculato-pardaline, apically subvitreous with 

 highly contrasted cinerous and blackish fus- 

 cous markings having sharply defined mar- 

 gins, the latter distributed very much as in 

 H. (A".) corallipes but very much diminished 

 ;n size, all the dark markings together not 

 covering one half the area of the tegmina, 

 very much reduced in the marginal field, and 

 in the distal portion of the discoidal field very 

 irregular in direction, often strongly arcuate 

 and generally also partially or completely 

 broken by the nervules into independent but 

 intimately connected maculations. Wings 

 very pale citron yellow at base with concol- 

 orous reticulation, apically vitreous with 

 black or partially fuscous reticulation, and 

 between the two a very narrow arcuate pale 

 fuliginous band scarcely broader than the 

 width of the interspaces, leaving at least six 

 marginal lobes free and separated by a brief 

 space from the humeral vitta, which extends 

 only as far as its inner border and inward the 

 larger part of the way to the base, followed 

 apically on the margin by a blackish fuscous 

 stigma. Hind femora cinerous with three 

 moderately broad, not very oblique, blackish 

 brown stripes externally, beneath and the 

 tibiae testaceous (presumably red in life), 

 the latter with black tipped spines. 



Length of body, 39 mm. ; of tegmina, 40 

 mm.
