296 NEW SPECIES OP AUSTRALIAN COLEOPTERA, 



Elytra narrow, with two distinct rows of shai^p conical tubercles 

 united at base and projecting on to prothorax; the outer row 

 contains six to ten and the inner slightly more tubercles; there 

 is also a short sutural row of from three to five smaller tubercles, 

 commencing at about the middle and terminating at summit of 

 posterior declivity; space between tubercles irregularly punctate; 

 sides with four rows of large punctures, two of which are 

 marginal; posterior declivity with small granules and punctures; 

 apices rounded, very feebly emarginate. Sterna sparsely punctate 

 and with irregular depressions. Two basal segments of abdomen 

 with irregular depressions and ridges, all irregularly and 

 (especially the apical) coarsely punctate at sides, a few feeble 

 punctures across the middle; apical segment with a distinct 

 circular squamose fovea in its middle. Legs long, setose; femora 

 moderately stout; anterior tarsi with an elongate pad on each 

 side, the rest not j^added. Length 17, rostrum 2|; width 6 mm. 



^aJ._Geraldton and Mullew^a, W.A. 



I have two specimens, one of which is almost scaleless and has 

 the elytral extension larger, more obtuse and more obtusely 

 granulate than in the other. The species, on account of the 

 number of rows and sharpness of its elytral tubercles, should be 

 very distinct from any previously described. The number of the 

 tubercles in each row is never to be depended upon, as in most of 

 the species I have examined they vary in number even on the 

 same specimen. 



DiALEPTOPUS LONGIPES, n.sp. 



Narrow, deep, elongate-elliptic, subopaque. Black ; elytral 

 tubercles dull red, legs piceous, antennas black. Rostrum and 

 apex of prothorax with short blackish setaj; muddy-brown scales 

 on head between eyes, and very small and indistinct muddy scales 

 on prothorax and elytra. 



Rostrum almost impunctate, otherwise as. in the preceding. 

 Prothorax as in the preceding except that the crests become 

 united at extreme apex and overhang the head as one, the lateral 

 oblique lidge being more pronounced and less granulate. El3'tx'a
