APOMECYNINA:. ’ 
DIAXENES, n. gen. 
General characters of Apomecyna, but a little less parallel 
in outline, the elytra being more narrowed towards the anex. 
Antennal tubercles a little more prominent and more approxi- 
mate; face equilateral, very gently convex. LHEyes coarsely 
granular, not quite so deeply emarginate. Antenne reaching 
two thirds of the length of the elytra, moderately stout, 
finely ciliate below ; the basal joint three times as long as 
broad, only very slightly narrowed at the base; third a little 
longer than the first and second taken together, slightly bent, 
and distinctly narrower at the base than at the apex; fourth 
joint three quarters the length of the third; the fifth a little 
more than half the length of the fourth ; the following joints 
gradually but only slightly diminishing in length and thick- 
ness. ‘Thorax a little broader than long, subcylindric, a little 
narrowed in front. Scutellum transverse. Hlytra at the base 
one quarter broader than the thorax, not quite fourtimes as long, 
moderately narrowed towards the apex, flattened at the suture; 
at the base, gradually declivous from just behind the middle 
the apex ot each elytron obliquely truncate. Legs short and 
stout; the femora considerably inflated. Intermediate tibiee 
with an incision on the outer edge at the apex. ‘T'arsi short ; 
claws diverging. Prosternal process sloping down posteriorly. 
Mesosternal process rather broader than the prosternal, 
sloping down in front. 
The species on which I propose to found this genus very 
much resembles some of the smaller species of Hathliodes. It 
differs from Apomecyna chiefly in the proportions of the an- 
tennal joints (which also diminish in thickness and are ciliate) 
? 
the even surface of the thorax, and less parallel form.
