Male, elongate oval, pale brownish yellow, a percurrent line from 

 base of vertex to posterior angle of scutellum, dark fuscous; this 

 latter is double on the middle lobe of the pronotum, and there is a 

 varyingly pronounced fuscous oblique line on each side of the pos- 

 terior lobe, meeting this double line at the base of the middle lobe. 

 The tegmina are variable, usually they are almost immaculate, but 

 may be darker, or even a little reddish tinged, and marked with fus- 

 cous; they are lightly and sparsely punctured with fuscous, but more 

 closely along the subcostal cell. Membrane pale cinereous, veins a 

 little darker. The antennae are yellowish, as regards the first two 

 segments, a blackish annulus near the ap.ex of the second; the others 

 dark fuscous. The legs are yellowish, the base of the hind femora, 

 a few faint mottlings on all the femora, apex of tibiae, etc., fuscous. 

 Urotergites fuscotestaceous, the pygophor yellow, a spot on the apex 

 and a line down the middle near the apex, blackish; the pleurites are 

 yellowish, not chequered, but have a sanguineous line down the mid- 

 dle. Sternites and mesotemum yellowish, the lateral margins 

 broadly dark fuscous or blackish. The first and fourth segments of 

 the antennae are subequal, each also subequal to the length of the 

 head in profile; the second and third segments of the antennae are 

 subequal, and each about one-half longer than the first. The labium 

 extends to the middle coxae. The eyes do not occupy the whole of 

 the head, either dorsally or ventrally in profile. Pronotum very 

 slightly elevated, (fig. 7). Tegmina elongate, slightly rounded exter- 

 iorly, apical angle of corium extending as far as the apex of the 

 abdomen, acute; membrane extending well beyond the abdomen, nor- 

 row, much longer than wide, the basal angle formed by the two 

 membranes in repose, acuminate, (fig. 18). Blade of hook broad, semi- 

 circular, angulate apically and dorso-basally. 



Female very similar to the male, but the abdomen is wider, expos- 

 ing the pleurites about the middle; the pleurites yellow, with a fus- 

 cous spot on the outer half of each segment basally, this spot not 

 extending to the inner margin. 



Length: Male, 10 mill.; female, 10 1/^ mill. 



Hab. Oahu, all over the Koolau range, or at least the south- 

 ern part. I have also seen an example from West Maui, that I 

 cannot separate. It may often be beaten from Acacia koa and 

 Nani polymorpha, as also from various Ferns, but it seems to be 

 really a ground species, like all its subcongeners, and is common 

 in the grass on the top of Mt. Tantalus, at 2000 ft.

Reduviolus silvicola Kirkaldy, 1908, P. Haw. E. S. I. 

 This is doubtfully valid, only a single female being known, 

 but it is more elongate, and darker than lusciosus, and the pro-
