212 STUDIES IN AUSTRALIAN ENTOMOLOGY, 



Length 11, breadth 4 mm. 



Mab. — Dabee, New South Wales. 



A single specimen {^) from Dabee is in the Australian Museum ; 



also one (9) from the Hunter River which, though a little larger is 



evidently identical. It is a distinct species among those at present 



described. 



Promecoderus interruptus. 



P. interruptus, Macl. I.e. p. 331. 



I have examined the type specimen (9) in Sir William Macleay's 

 collection. It is closely allied to P. hunieriensis and P. loilcoxi, 

 with the latter of which it may be identical ; the chief differ, 

 ence seems to be the punctures of the elytral stride, a character to 

 which I attach little importance. The marginal border of the 

 prothorax is very lightly subsinuate before the base, and is entire 

 on the base, though hardly marked in the middle. The ventral 

 segments have a round fovea on each side. The prothorax is 

 convex, and the elytra is a little ilattened along the suture on the 

 basal half. The following are the measurements : — 



Length 12|, breadth 4|, prothorax 3| x 3|, elytra 7 x 4|mm. 



Hah. — Clarence River. 



Promecoderus wilcoxi. 



P. xoilcoxi, Casteln. I.e. p. 171 ; Putz. Revis. 1873, p. 333. 



This species I have never seen ; it is, however, from the descrip- 

 tion, allied to P. hunteriensis, Macl. ; de Castelnau's description 

 is very poor, so I append a translation of that of M. Putzeys. In 

 this the size is omitted, and in de Castelnau's work a misprint 

 occurs about the size, but I believe 6J lines is intended to be the 

 length given. 



Of a coppery black, palpi and antennse brown ; the apex of 

 the first joint of the antennae is of a testaceous red. Tooth of the 

 mentum rather wide, truncate at the apex. The impressions 

 between l^the antennae are wide and deep ; two others, equally 

 distinct, are noticeable between the eyes ; the post-ocular promin- 

 ences equal half the eyes. The prothorax is cordate, not ex- 

 tending beyond the eyes at the anterior angles, widening behind 

 to about the anterior third, then narrowing in a curved line to
