suddenly diminishing to base; with or without two large shallow 

 discal impressions; punctures much as on head. Elytra strongly 

 inflated posteriorly, with feeble punctures. Abdomen wide, but 

 narrower than elytra. Legs rather short. Length 2|-3^ mm.

In the male the sides of the prothorax are widest and almost 

 pointed just before the middle; between here and the base is a 

 distinct notch, but this is not traceable from some directions. In 

 the female the sides are not notched, and at their widest are 

 slightly rounded. The lower surface, except of head, is more or 

 less piceous. The semilunar markings of the elytra are not 

 always sharply defined, and in one specimen extend to the apex. 

 The Tasmanian specimens were taken beneath the rough bark of 

 apple trees. The colour and the shape of its prothorax will 

 readily distinguish it from the previously described Australian 

 species. 



Family LATHRIDIIDvE. 



Two papers in which Lathridiidse have been recorded from 

 Australia appear to have escaped observation by Australian 

 entomologists. These are by Motschulsky* and Reitter.f The 

 former first J recorded Lathridius nodifer, Westw. (p. 260) from 

 New Holland, but placed it in his genus Aridius; according to 

 him, also, (p. 262) L. antipodum White,§ is one of its s} r nonyms. 

 Melanophthalma gibbosa Herbst, (p. 287) is also recorded by him 

 from New Holland. Herr Keitter records (p. 96) Corticaria 

 pubescens Illiger and Monotonia picipes Herbst, (p 96) from 

 Australia. 



MONOTOMA QUADRICOLLIS Aube. 



This species has been introduced to Tasmania. I sent some 

 specimens to Mr. Champion, to whom I am indebted for the 

 name.
