soc. Philad.), Maryland (Uhler), 

 Georgia (Morrison in Henshaw's col- 

 lection), Illinois (Strumberg in Hen- 

 shaw's coll.), southern Illinois (Ken- 

 nicott), Republican Fork, Kansas (Lt.

 West Point, Nebraska, and Glendive, 

 Montana! (Bruner), and from Dallas 

 (Boll), San Antonio (Lincecum), and 

 Bosque Co., Texas (Belfrage). Saus- 

 sure in addition reports it from Mis- 

 souri, Thomas from the District of 

 Columbia, Nebraska, and Dakota ; and 

 Walker (in whose correct determina- 

 tion of the species I have no confidence) 

 from Nova Scotia, New Jersey, and 

 Vancouver Island. It seems to be a 

 southern species, rarely occurring in 

 the north. Belfrage says that in Texas 

 it is a rare species found on prairies in 

 October. 



Hippiscus (H.) compactus sp. no v. 



A compact and stout though not very 

 large form. Very dark brownish fuscous, 

 necked with blackish, the head stout and 

 full, very broad above, olivaceo-fuscous ex- 

 cepting above, where it is brownish fuscous 

 with broad median and lateral longitudinal 

 dull olivaceous stripes ;summit of head sparse- 

 ly punctate, nearly smooth with very slight 

 signs of transverse rugae; vertical scutellum 

 indistinct, with slight and low bounding 

 walls, broader than long in both sexes, faintly 

 quadripartite; lateral foveolae slight, elon- 

 gate, triangular; frontal costa broad, flat, 

 punctate, slightly depressed at the ocellus, 

 subequal, at upper extremity faintly bifoveo- 

 late. Antennae pale cinereous at base, dark 

 fuscous apically. Pronotum stout, but not 

 expanding greatly on the metazona, the dor- 

 sal area nearly flat and tolerably uniform 



except for the more or less longitudinal glis- 

 tening rugae which are rather sparse and not 

 very elevated; median carina very uniform 

 and not prominent or arcuate; lateral 

 canthi tolerably well pronounced on the 

 metazona, distinctly and considerably sur- 

 passing the median sulcus; angle of poste- 

 rior margin slightly exceeding a right angle ; 

 lateral lobes densely punctate on the meta- 

 zona. Tegmina cinereous, becoming semi- 

 pellucid apically, heavily banded with black- 

 ish fuscous in tolerably regular transverse 

 subequidistant stripes, with very little ob- 

 liquity, broader in the proximal than in the 

 distal half of the tegmina; they are subcon- 

 tinuous in the marginal and discoidal areas, 

 and the axillary area is fuscous with three or 

 four small blackish spots seated on the anal 

 vein ; sutural stripe distinct and yellowish 

 cinereous; the spot at extreme base of the 

 outer discoidal area is completely amalga- 

 mated with that below and slightly within in 

 the inner discoidal area; the outer stripes 

 are slender, more or less maculate, and do 

 not reach the lower margin of the tegmina. 

 Wings pale lemon-yellow at base with a 

 pretty broad, blackish fuscous, arcuate band 

 scarcely reaching the anal angle and touch- 

 ing the margin only at the 5th (£) or 6th 

 f $) lobe; it is not narrowed above, is sepa- 

 rated from the humeral stripe by a testaceous 

 line, the stripe reaching nearly to the base ; 

 apex hyaline, or in the $ slightly infuscated 

 next the margin above, all the veins blackish. 

 Hind femora clay yellow within banded with 

 black, dull cinereo-fuscous without, oblique- 

 ly banded with blackish fuscous; hind tibiae 

 brownish yellow, more or less infuscated ex- 

 cept in a broad band just beyond the base, 

 spines black tipped.
