facial scutellum decidedly transverse, not of almost equal height and 

 width, and with markings and coloration different. 



Type. — cf ; Obi Island, Moluccas. [Hebard Collection Type No. 

 524.] 



Size small, form rather slender for the genus. Ocelli large, closely 

 placed, arranged in a triangle slightly broader than high. Facial 

 scutellum transverse, height approximately three-fifths basal width; 

 vertical parallel carinse subobsolete, the two lateral sections of the 

 scutellum each with a small dark brown suffusion mesad; dorsal 

 margin of scutellum moderately convex, showing an indication of 

 mesal angulation. Pronotum as in laevicollis, except that all trace 

 of medio-longitudinal carination on the shaft is lost; supra-coxal 

 expansion moderate, more decided than in H. venosa (Olivier), as 

 in laevicollis, very slightly weaker than in H. sorongana (Giglio- 

 Tos), margins smooth, caudad briefly margined with a narrow dark 

 suffusion as in this sex of laevicollis, this feature indicated to a much 

 less degree in the male of sorongana before us. Tegmina and wings 

 much as in laevicollis, extending well beyond apex of abdomen; 

 marginal field opaque, broad proximad, narrowing rapidly mesad, 

 very narrow in distal half; remaining portions clear hyaline, with 

 cross-veinlets brown for a brief distance from each vein; stigma 

 small, linear, hardly opaque. Limb armament exactly as in laevi- 

 collis. Cephalic coxae with cephalic margin armed with (six and 

 eight) very small bluntly conical teeth. Cephalic femora with 

 genicular areas each supplied with a small blunt spine; ventro- 

 internal margin with the following formula, ililililililiil, these 

 spines black tipped, the larger spines of this series as well as the 

 first and third discoidal spines taAvny, with a distinct basal suffusion 

 of this color on the limb except for the discoidal spines. Cephalic 

 tibiae with eleven ventro-external and fourteen ventro-internal 

 spines, the external series beginning a slight distance from the tibial 

 base. Caudal metatarsus approximately equal in length to that 

 of the succeeding joints. 



Allotype. — 9 ; same data as type. [Hebard Collection.) 



Agrees closely with this sex of laevicollis, differing in the smaller 

 size and facial scutellum, which is as described for the male of this 

 species, thus differing only in having the dorsal margin more broadly 

 convex. Compared with the male type of this species, this sex is 

 seen to differ in the more robust form, ocelli which are much smaller 

 and more widely spaced, pronotum with lateral margins micro- 

 scopically denticulate before the supra-coxal expansion, minutely
