484 Mr. F. P. Pascoe on some new or little-known 
sterni receptum. Metasternum breve. Processus interfemoralis antice 
rotundatum. Corpus naviculare, supra depressum. 
The outline of this insect, resembling a broad species of Elater, 
and its flattened form, will readily distinguish it from all other 
genera of the subfamily to which it belongs. 
Cymbeba dissimilis. (Pl. XIX. fig. 8.) 
C. znea, nitida; prothorace basi bifoveolato ; elytris striato-punctatis, in- 
terstitiis punctulatis. 
Hab. Australia. 
Dark brassy brown, shining; head finely punctured, two fovez be- 
tween the eyes; clypeus separated from the front by an arched line ;

fovea on each side at the base; elytra striate-punctate, the punctures 
small and rather distant, the intervals between the striz minutely 
punctured, the sides, abruptly declivous, shade off at the shoulder and

lobo interno mutico. Zabiwmn antice rotundatum. Mentum trapezoi-

inermes ; tars? art. primo subelongato, -Antepectus brevissimum, pro- 
sterno producto. Mesosternum cavitate A-forme. Metasternwm incur- 
vatum. 
Allied to Oplocheirus, Lac. ; but, besides other characters, such as 
the unarmed internal maxillary lobe, &e., it is radically distin- 
guished by the arching of the elytra, which may be traced along 
their margins and epipleurs, and to which the concavity of the 
metasternum corresponds. 
Alymon prolatus. 
A. cupreo-fuscus, nitidus ; prothorace subtiliter, elytris striato-punctatis, 
his interstitiis vage punctatis. 
Hab. Natal.
