626 Prof. Westwood's Descriptions 



Callipyrga of Newman ; so that strictly speaking the genus 

 Zygocera still remains uncharacterized. The following are its 

 most prominent features : — 



Hypselonoto affine. Caput angustum, oculis haud prominulis. 

 Antennae ad basin valde approximatae, ll-articulatae, articulo Stio 

 in masculis (saltern speciei typicalis) longissimo et ad apicem 

 fasciculato. Prothorax conicus, capite multo latior, ad basin con- 

 strictus, dorso tuberculatus lateribusque versus basin utrinque 

 unispinosis. Elytra ad basin prothorace multo latiora, convexa, 

 singulo inter scutellum et humeros tuberculo erecto armata et ad 

 apicem oblique truncata. Pedes mediocres.

 Habitat in Nova Hollandia. In Mus. Hopeiano Oxoniae. 

 I believe that no detailed description, beyond Boisduval's 

 diagnosis of seventeen words, has hitherto been published of this 

 species, which is the only one referred to by Dejean in his 

 Catalogue. 



The face, which is black and shining, is marked with two fine 

 white lines, extending from the sides of the clypeus to the bases 

 of the antennae ; another white line extends from the base of the 

 mandibles to the back of the eyes, and the front margin of the 

 prothorax is also marked with a still finer white line. The eyes 

 are kidney-shaped, but the upper division is very small. The 

 antennae are black, slightly varied with whitish, the fourth joint 

 being most conspicuously marked with a broad band of this colour. 

 The fascicle of hairs at the extremity of the long third joint in the 

 male is black. The two lateral tubercles near the base of the 

 prothorax, together with the three on the disc, form a transverse 

 series. The scutellum is small, triangular, and rounded at its
