H, validi similis sed angustior, tuberculis prothoracis minoribus ; plaga fusco-rufa. 
There is nothing to separate this insect from Mr Blandford’s species, as far as can be 
seen in the single specimen before me, except the slight differences mentioned above. 
Loc. Seychelles. Silhouette: Mare aux Cochons, over 1000 feet, IX. 1908, one 
specimen. 
The typical form of H. validus was described from Mexico: the very closely-allied 
H. opacus Hichh. is known from South America.

In the males, the tubercles on the prothoraciec anterior edge are divided into two 
groups by a central narrow longitudinal space which can be traced some distance 
posteriorly ; the anterior half of the prothorax is more depressed than in the females and 
is more acutely rounded apically, the male elytra also terminate more acutely ; when 
viewed dorsally the male is slightly shorter and narrower than the female with the sides 
somewhat curved, and laterally the declivity of the elytra is more abrupt than in the 
latter sex, but these differences vary considerably in individuals of the series and form no
