[December 1S92 



posterior margin of the fastigium of the 

 vertex; this distinct, plane, as broad as long, 

 open behind, closed by a V-shaped carina 

 in front, the walls low but distinct and in the 

 middle angulate ; median carina when present 

 terminating in the middle of the fastigium ; 

 lateral foveolae very distinct, elongate tri- 

 angular, including between their tips the 

 equally deep biareolate foveola, which in the 

 5 is sometimes confluent with the sulcus of 

 the frontal costa; the latter moderately 

 broad, subequal, but slightly contracted at 

 summit, more or less sulcate throughout 

 above with a slight median carina. Pronotum 

 compressed, but little expanded on the 

 metazona, plane above, the process of meta- 

 zona rectangulate, the median carina slight, 

 equal, straight, uninterrupted between the 

 sulci, the lateral carinae slight and confined 

 to the metazona, the dorsal surface longi- 

 tudinally rugulose with short vermiculations 

 more crowded, transverse, and subdued on 

 the lateral lobes of the metazona. Tegmina 

 dark brownish fuscous marked with dark cine- 

 reous after the fashion of H. (A'".) neglectus 

 and as there somewhat variable, the sutural 

 stripe hardly visible. Wings pale citron on 

 basal half with corresponding reticulation 

 (except where the humeral vitta runs in nearly 

 to the base), blackish fuliginous beyond, the 

 apex of the two uppermost lobes generally 

 more or less vitreous with black reticulation, 

 at the most occupying a triangular area which 

 takes in less than a fourth of the costal mar- 

 gin, and is then generally abridged by the 

 infuscation or infumation of the extreme apex. 

 Hind femora dark grayish cinereous exter- 

 nally, crossed obliquely by three obscure, 

 moderately narrow, dark fuscous stripes, 

 internally black with apical and postmedian 

 transverse luteous stripes, inferiorly luteous 

 often with a reddish tinge; hind tibiae 

 rather pale coral red, apically often becoming 

 luteous, the spines black tipped. 



Length of body, $ , 22 mm., $ , 28.5 mm. ; 

 of tegmina, $, 22 mm., §, 27 mm. 



Described from 2^,3?, obtained 

 by G. R. Crotch in British Columbia. 



This species is closely allied to H. 

 (A''.) neglectus, from which it is to be 

 distinguished mainly by the greater 

 breadth of the dark markings on the 

 wings, the darker colors of the body 

 and tegmina, and far less brightly con- 

 trasted sutural stripe of the latter.

This species is somewhat variable, 

 especially in the markings of the teg- 

 mina, which at one extreme resemble 

 those of species of Trimerotropis, at 

 the other those of Encoptolophus, and 

 in some are almost entirely of a warm 

 brown color with concolorous sutural 

 stripe and the merest clouds of lighter
