yellowish- white. Elytra each with a narrow transverse white band 
placed a little in front of the middle, and made up of short, 
closely-placed decumbent white setse. A minute transverse spot of 
similar white setae may be seen on each side of the prothorax 
lying alongside a very feeble oblique elevation or tubercle. Long.

Hah. Grenada — Balthazar, Telescope Est., and Lake 
Antoine Est., all on the Windward side (H. H. Smith). 
This species closely resembles Myrmolamia penicillata. 
Bates, but it is smaller even than that small species, and 
is easily distinguished from it by its 10-jointed antenna) 
and the absence of a distinct centro-basal tubercle from 
the elytra.

Colour slightly variable. Head and prothorax in some examples 
almost entirely dark brown, in others testaceous, largely suffused 
with dark brown. Elytra punctured at base, sparsely pubescent, 
yellowish-testaceous, with four glossy dark brown patches on each, 
one oblong, just below and behind the shoulder ; the second trans- 
verse, placed at the middle and, at the side of the elytron, joined 
to the third, also transverse, which lies a little behind it ; the 
fourth, somewhat rounded, situated near the apex. A small in- 
fuscate area is present also, in some examples, around the nearly 
obsolete centro-basal tubercle of each elytron. Legs pale testaceous, 
with the clubs of the femora and the apices of the tibiae more or 
less distinctly infuscate. Abdomen dark brown and glossy. 
Antennae testaceous, with the apices of joints 1st and 3rd to lOth
