HlPPISCUS (X.) PARADOXUS. 



Oedipoda paradoxa Thorn.!, Rep. U. S. 

 geol. surv. terr., v, 457 ; 6, 720-721 ; Svn. 

 Acrid. N. A., 132. 



Not Oe. paradoxa Glover. 



Brownish fuscous, of robust form and me- 

 dium size. Head dark above, cinereous or 

 pallid below, often marked laterally by two 

 narrow oblique brownish fuscous stripes, one 

 running from behind the eyes across their 

 iower edge to the middle of the frontal costa, 

 the other parallel to and distant from it 

 across the lower part of the cheeks ; rugose 

 above including the fastigium of the vertex 

 which is as broad as long and bordered in its 

 entire circuit, sometimes less distinctly in 

 front and behind, by strongly sinuous sharp 

 and moderately high bounding walls; lateral 

 foveolae moderately deep, short triangular, 

 including between their tips a distinctly 

 biareolate broad oval deep foveola ; frontal 

 costa almost exactly as in H. (-5T) tigrinus 

 but sulcate more deeply and for a longer 

 distance and expanding more considerably at 

 base. Pionotum shaped as in H. (A".) ti- 

 grinus and as there rather deeply stabbed on 

 either side of the middle of the front margin 

 of the metazona, the latter more vaulted, the 

 rugosities especially in ? profuse, subarena- 

 ceous, elevated, blunt, and pretty uniformly 

 distributed; median carina of metazona pretty 

 strongly arched but still rather sliglft and 

 low; lateral carinae generally distinct and 

 sharp but slight; lateral lobes nearly smooth 

 in $ . bluntly rugulose in 9- ; dorsum some- 

 times marked by a broad bent ashen band on 

 either side. Tegmina cinereous, very heav- 

 ily barred with dark brown, on the costal 

 margin sometimes blackish, transverse bands 

 nearly or quite crossing the tegmina, almost 

 or quite confluent below and occupying four- 

 fifths or considerably more. of the tegmina, 

 extending to the tip, so that the tegmina 

 may be rather regarded as brown with nar- 

 row transverse ashen stripes broadening 

 above, one ashen patch larger than the 



others usually found situated on the costal 

 margin, its outer limit at the middle of the 

 margin; a rather broad sutural stripe be- 

 neath which the tegmina are almost or quite 

 wholly brown. Wings pallid at base with a 

 citron tinge, the veins and cross veins of the 

 same color, vitreous apically, with occasion- 

 ally a fuliginous cellular spot or two near 

 the apex, the reticulation black with a 

 narrow rather strongly arcuate fusco-fuligrn- 

 ous median band, occasionally broadened a 

 little, especially in the middle of its course, 

 leaving about four marginal lobes free, sepa- 

 rated by an often scarcely perceptible yellow- 

 ish line from the humeral vitta, which reaches 

 to the outer limits of the upper extremity of 

 the arcuate band and extends nearly (?) or 

 less than three quarters way (<J) to the base, 

 the costal margin testaceous interrupted with 

 fuliginous at the extremity of the vitta. 

 Hind femora pallid cinereous, with three 

 well defined, moderately broad, strongly 

 oblique, distinct dark brown stripes; be- 

 neath and within coral red like the tibiae 

 which are more or less pallid externally 

 especially at the base, the spines black tipped ; 

 hind tarsi luteous. 



Length of body, $ , 33 mm. ; $ , 37 mm. ; 

 of tegmina, $, 31 mm., ?, 37 mm. 



Described from 3 J , 7 9 •> most but 

 not all killed in alcohol. 



One specimen comes from Holt Co., 

 Nebraska (L. Brunei', May) ; the others 

 from Utah (Parowan, July 3-10, about 

 6ooo', near low mountains on an irrigated 

 spot; Alokiak Pass near St. George, 

 April 20-30, E. Palmer), Taos Valley, 

 N. Mex.,May30 (Brunei) and Arizona 

 (Ft. Whipple, E. Palmer ; also collected 

 by Dunn, Brunei). 



A single type of this species, a 9, ex- 

 ists in the National museum, dried after 

 immersion in alcohol, leaving no trace
