rather small. Clypeus scarcely depressed on each side. Lower 

 surface densely and rather coarsel}^ punctate, except in the 

 vicinity of the gular suture. Antennae extending to base of 

 prothorax, 1st joint almost as long as 2nd and 3rd combined, 

 2nd slightly shorter than 3rd, the others gradually decreasing 

 in length. Prothorax suboblong, somewhat depressed, very 

 slightly narrower than the head; punctures as in the preceding 

 species. Elytra slightly longer and slightly wider than prothorax, 

 apex conjointly feebly emarginate, and with a very narrow raised 

 rim; with series of moderately large punctures on the disc, but 

 irregular at the side. Abdomen parallel-sided to near apex, 

 densely punctate (both surfaces); lower surface of 6th segment 

 feebl}'' emarginate. Length 8, to apex of elytra 4|^ mm. 



Q. Differs in having a smaller head and simple abdomen. 



Hah. — New South Wales. 



The colour of this insect is sufficient to distinguish it from all 

 previously described species. The punctures on the clypeus are 

 no sparser than elsewhere on the head. About six rows of 

 punctures can be seen on the disc of each elj'tron; of these, how- 

 ever, the second row consists of but few^ punctures, which are 

 usually placed beyond the middle, so that the first row appears 

 to be separated from the 2nd (but reall}^ the 3rd) row by a con- 

 siderable space; the true 4th row, though quite regular, contains 

 considerably smaller punctures than the 3rd or 5th. 



I have taken specimens of this species and its variety (described 

 below) from flood debris of the Tweed, Clarence, Hawkesbury and 

 Peel Rivers, but unfortunately I confused the localities, so that 

 I cannot now say where each comes from; they are, however, all 

 from New South Wales.

Differs only in being slightly smaller (7 mm.), and by having 

 the abdomen entirely black. 



Myrmedonia clavigera, Fvl. 



M. Fauvel describes the abdomen of this species as blackish- 

 piceous. One specimen under examination has the abdomen
