430 Prof. Westwood's Descriptions 



The mandibles are about the length of the head, elongate-ovate ; 

 concave, with two or three small rounded lobes on the upper mar- 

 gins. The maxillae are simple, the upper lobe being triangular 

 and strongly penicillated ; the palpi have the 2nd joint longer than 

 the rest. The mentum is triangular, fixed on the fore-margin of 

 a broad transverse deflexed projection of the jugulum, the anterior 

 portion of the labium being hidden by the produced angle of the 

 mentum. The antennae are short, with the capitulum formed of 

 the six terminal joints, which are moderately produced on their 

 inner angles. The eyes are entirely divided by the broad trun- 

 cated septum. 



The prothorax is of moderate size, much broader than the head, 

 but narrower than the middle portion of the elytra ; the anterior 

 angles are rounded, but the posterior ones are obliquely emargi- 

 nate; the lateral margins are serrated and the disc has an impressed 

 channel along the middle, a curved impression on each side be- 

 hind the eyes, the sides deflexed and very rugose, and another 

 impression on each side within the posterior angles extending 

 towards the disc. The elytra are broad and convex, dilated be- 

 yond the middle, very delicately punctured, especially towards the 

 sides ; the suture elevated and transversely and obliquely wrinkled. 

 The legs are robust, the anterior tibiae broad, with about six 

 serratures at the base and two strong teeth at the extremity of the 

 outer margin. The fore posterior tibiae have two spines on the 

 outer margin, one near the middle and the other towards the base. 

 The body beneath is obscure black, 



I am indebted to Robert Bakewell, Esq., F.L.S., for an op- 

 portunity of describing and figuring this remarkable insect, which 

 I presume to be a female specimen. Since the above description 

 was in type. Dr. Howitt has sent a drawing of another specimen 

 to England from Australia.

I have only seen a single female specimen of this specie's, the 

 diagnosis of which is therefore for the present only provisional ;
