STICTHIPPUS (o-tiktos , iiriros) subgen. nov. 



Head closely resembling that ofHippiscus, 

 with small but deep and conspicuous trian- 

 gular lateral foveolae, and between their an- 

 terior extremities a distinct, depressed, 

 transversely biareolate field; frontal costa 

 sulcate above, especially about the ocellus. 

 Antennae rather slender, uniform through- 

 out, about as long as head and pronotum 

 together in the 5 , less than twice as long as 

 the pronotum in the $ , apically tapering 

 only on last joint or two. Pronotum with 

 the dorsal field nearly flat with a slight 

 median carina which is occasionally' subob- 



diflers from all most strikingly in the 

 form of the mesosternal lobes which lie 

 at about the same distance apart as in 

 the two first, to which it is certainly 

 most nearly allied. From Leprus it 

 also differs in the presence of a humeral 

 taenia on the wings. It agrees better 

 with Hippiscus than with Xanthippus 

 in the structure of the antennae and of 

 the median carina of the pronotum, 

 although itself very variable, and from 



solete on the posterior part of the metazona Hippiscus it may be separated also by 



the biareolate sunken fastigium between 

 the lateral foveolae of the face. 



Hippiscus (S.) califorxicus sp. nov. 



A compact form of rather small size. Very 

 dull brownish fuscous, with a slight yellow- 

 ish tinge, faintly flecked or blotched with 

 dusky spots and obscurely dotted with black, 

 the head plump and full, dark on the upper 

 third, the rest dull clay yellow and nearly 

 free from dots; summit of head nearly 

 smooth, with a few dull low minute verru- 

 cosities. a faint median carina and the walls 

 of the vertical fastigium dull but distinct; 

 lateral foveolae small, triangular, rather 

 deep; frontal costa moderately narrow, suh- 

 equal, contracted very slightly at summit 

 and again a little more distinctly beneath the 

 ocellus, rather deeply sulcate especially- below 

 tne ocellus. Antennae testaceous, infuscated 

 in apical half, a little longer (J) or a little 

 shorter (J) than head and prothorax to- 

 gether. Pronotum stout, especially in the 

 $ . the metazona very faintly tumid, its 

 lateral carinae sharp anteriorly especially in 

 the J ; dorsal field of whole pronotum some- 

 what minutely verrucose. many of the verru- 



and normally cut only by the typical sulcus, 

 but sometimes slightly cut by the anterior 

 sulcus of the prozona and more or less inter- 

 rupted behind it, in which case there is a 

 distinct discal scutellum, the posterior sulcus 

 of the prozona terminating in two forks, one 

 at the lateral borders of the discal scutellum, 

 the other by deeply cutting the lateral walls 

 of that scutellum close to the median line; 

 metazona distinctly longer than the prozona. 

 rectangulate or obtusangulate behind; sur- 

 face scabrous, the lateral carinae obscure. 

 Tegmina as in Hippiscus, with scattered 

 maculations hardly pantherine. Wings with 

 the whole outer border broadly infumate, 

 subvitreous apically so as to give the inner 

 part the semblance of an arcuate band, and 

 connecting with a broad humeral taenia 

 which extends nearly to the base. Legs as 

 in Hippiscus. Mesosternal lobes separated 

 by a deeply truncate cuneiform median piece, 

 the inner margins of the lobes being rapidly 

 and widely divergent. 



This subgenus is closely allied to the 

 other subgenera of Hippiscus, — Hippis- 

 cus and Xanthippus. and to Leprus. It
