Body oblong or elongate, depressed : head somewhat large or some- 
what so produced, apical margin acute, more or less broadly foliaceous : 
face dilated, somewhat deeply sinuated below the eyes; frons a little 
convex: eyes small or moderate : ocelli placed on the apical margin of 
the head or at or near the eyes : thorax transverse, very obtusely round- 
ed at the apex: scutellum triangular, a little broader than long: tegmi- 
na almost as long as the abdomen, margined at the apex, valvate behind 
the clavus, with five apical areas: feet moderate, posterior tibise very 
spinose. Allied to Siva, Stal, but differs in the head larger, more pro- 
duced, margin foliaceous (Stal).

Hecalus sulcatus, Signoret, A. 8. H. F. (5 sér.) ix, p. 272, t. 8, f. 28 (1879). 
Sordid yellow: vertex parallel, parabolic in front, angles very ob- 
tusely rounded : prothorax with four elongated cavities in front, finely 
striated transversely behind: tegmina transparent, as long as the abdo- 
men: veins strong, yellowish, not margined ; a blackish dot at the point 
of the clavus : abdomen above with two bands of small brown patches, 
two at the base of each segment : feet entirely sordid yellow, unicolo- 
rous: ventral segments parallel, median lobe obtusely salient, sides sinua- 
ted (Mieber). 2, body long, 11 millims. 
Reported from H. India. Signoret considers this species to be probably 
one with H. parva, Walker (ist 1, p. 828), though he gives the latter 
also with a? asa synonym possibly of H. paykulli, Stal, who, however, 
makes it a Selenocephalus in Ofvers. K. V.-A. Foérh. p. 494 (1862).

Sordid whitish-yellow, smooth, shining, clouded with brown on the 
vertex, the length of the median line, and transversely on the prothorax, 
the tegmina and the veins of the same colour but with a brown line on 
each side. Head defined on the margin only, one and half times longer 
than the prothorax, as long as broad between the eyes, angularly round- 
ed, the sides almost parallel above the eyes, then forming an angle 
at the tip ; two excavations on the vertex on each side. Frons convex 
with a foliaceous border anteriorly, grooved on the sides, border con- 
cave above the clypeus which is itself broader at the base than at the 
tips but showing its greatest breadth in the middle, carinate in its 
median part. Rostrum very short. Genz with the tip oblique from the
