as in the corresponding sex of Hammatocerus.

Of this species we possess a long series of examples from within our limits, these 
agreeing perfectly with one of Stal’s types of H. annulipes now before me. Perty’s 
figure, there can be little doubt, must have been taken from a specimen of the same 
species, the differences observable being evidently due to the imperfect drawing of the 
artist. ‘The coloration of the pronotum and elytra is quite constant. A male from 
Pantaleon is figured.

Three specimens (two males and one female) of this insect were found by myself at 
San Gerénimo ; the type has been seen.
