transversely convex, very minutely punctured, its middle third 
with a broad but shallow transverse depression, which is rather 
more deeply excavated on either side of the median line. Elytra 
convex, not excavated below the basilar space, minutely but not 
closely punctured ; outer disk of each elytron in the d with a 
large oval fovea, which commences at some little distance below 
the humeral callus and extends downwards as far as the middle 
line. Elytral epipleurse extending for a short distance below the 
middle. Anterior acetabula closed.

— Auguste ovata, postice paullo ampliata, convexa, rufo-testacea, nitida, 
tibiis tarsisque nigris aut nigro-piceis, antennis pallide flavis, articulo 
ultimo nigro ; tliorace quam longo latiore, convexo, laevi ; elytris 
convexis, tenuiter punctatis; nigris, apice sanguineis. Long. 2|-

Mas. Elytro utroque ante medium fovea magna subovata male definita, 
extus late sed leviter elevato-marginata, fundo leviter excavata, im-

Sab. Java (Guerin), Borneo, Sumatra (Wallace, Raffles). 
Antennae filiform, the third joint one half longer than the 
second ; pale flavous ; the terminal and occasionally the upper 
half of the penultimate joints more or less stained with black. 
Thorax about one fourth broader than long ; sides nearly straight 
and diverging from the base to the middle, thence rounded and 
converging towards the apex, the anterior angles thickened and 
produced, obtuse, hinder angles acute ; hinder margin obtusely 
rounded; disk convex, smooth, impunctate. Elytra oval, convex, 
finely but not very closely punctured ; on the anterior disk of each 
elytron in the S (the only sex known to me) is a large, very 
shallow and ill-defined excavation, the outer and hinder edges of 
which are broadly but slightly thickened.
