Tlw impressed points of the upper side of tlie body Ijear a very 

 small round whitish scale, visible only when viewed vertically from 

 above. The last antennal joint, which is missing in Dallas's type, 

 is pale testaceous. The tergum of the abdomen and the female 

 genital segment are castaneous. The apex of the femora is of the 

 same testaceous colour as the tibiae and tarsi. The male is still 

 unknown. 



I know only the brachypterous form of this in.sect, but Dallas 

 had before him both this form and an immature specimen of the 

 macropterous form. Although he does not mention it, I suppose 

 that the macropterous form has the pronotum somewhat broader 

 at the base with comparatively shorter anterior lobe, the ocelli a 

 little larger, and the corium less rounded at apex. It is probal>le 

 that Esuris and Lva also are pterygo-dimorphous, as the Australian 

 genus Euonder. Stal, has proved to be.

Smooth, shining, subglabrous, darkish testaceous, hemelytra and 

 abdomen opaque, the foi'mer fuscous, the latter greyish brown, 

 somewhat mottled witli pale testaceous, pubescent, more longly 

 pilose at and near apex, rostrum and legs pale testaceous, sparingly 

 shortly pilose. Head as long as the pronotum in the middle, basal 

 lobe slightly broader than long and a triHe l)roader than the width 

 across the eyes, somewhat flattened, its lateral margins moderately 

 rounded, eyes small, antennae about as long as head and half the 

 pronotum together, very slightly pilose, first joint very short, the 

 three following joints equal in length, each as long as the basal lobe 

 of the head. Pronotum a little longer than broad, basal margin 

 rather deeply arcuately sinuate, apical lolie a little broader than 

 head, with an extremely fine impressed longitudinal line in the 

 middle, median lobe one-third (<?) or one-fourth (?) narrower 

 than basal lolie, in the male subequably rotundately narrowing 

 toAvard apex, in the female subparallel from base to beyond middle, 

 then rather suddenly nariowed, in the middle with a longitvidinal 

 impression not widening posteriorly and not quite reaching the 

 base. The basal margin in the middle somewhat produced back- 

 wards over tlie apical part of the basal lobe, which is almost three 

 times longer at the sides tliaii in the middle, sliglitly ( $ ) or more^ 

 distinctly (c?) narrowed from base to apex. Scutellum broader 

 than long, somewhat flattened, the lateral margins straight. Heme-
