384 DESCRIPTIOXS OF KE\T SPECIES OF ArSTRALIAS COLEOPTERA, 



.5 mm. in length, it agrees well witli tlie description of haccaeformU (tlie sex of 

 the type of which was not noted), and tliat name appears to be varietal only; a 

 femaie (without locality) apparently belons-inj; to this variety is still larger. 5 nnn., 

 but its antennae and legs are all damaged. 



A male, from Ooldea in South Australia (the only specimen I have seen, 

 except from Queensland) also appears to belong to the species, but its antennae 

 are slightly shorter, not quite extending to the tips of the elytra, and only six of 

 its ioints are entirely dark, its metasteruum and abdomen, except for a median 

 space at the base of each, and most of its middle and hind legs are black. 



DiTROPiDUS JACOBTI Balv . 



A short, thick-set species with large eyes, almost touching in both sexes; the 

 elytra] striae are strong, and contain large punctui-es, the striae actually extend 

 to the suture ; on most species of the genus there are two or three, well-impressed 

 striae on each side, but towards the suture these are represented by rows of punc- 

 tures. The prothoracie punctures are strong and rather dense on the sides, be- 

 coming more or less sparse on the middle; the seventh joint of the antennae (first 

 of the club) is distinctly larger than any of the following joints in tlie male, and a 

 trifle larger than any of them in the female. The upper surface is usually of a dingy 

 testaceous, vai-ying to obscurely piceous, or even black, with the apical portion of 

 the elytra paler or not; occasionally there is a large infuscate blotch on the pro- 

 notum; the legs also vary from almost entirely pale, to almost entirely dark. 

 There are specimens before me from many localities in Xew South Wales, Vic- 

 toria, Tasmania and South Australia. 



Var. a. Some specimens! from New South Wales (Tamworth), Victoria 

 (Alps) and Western Australia (Pinjarrah and Mount Barker) differ from most 

 specimens of the species in having the prothorax with dense pimctures throughout, 

 the elytral striae are deep throughout, witli all the interstices strongly convex (on 

 the typical form the elj-tral striae although distinct, are not as deep as on this 

 variety, and the interstices near the suture are flat and wider than the striae), and 

 the upper surface is of a uniform pieeous-brown . A specimen from Victoria and 

 another from Tasmania resemble the variety, except that the ehira are obscurely 

 flavous at the tips. 



Var. B. a specimen frcjm South Austi-aliii ( Lucindak') is stniclnndly like 

 the preceding variety, but is flavous, exi-eiit that the metasternuiu and al)domcii 

 are deeply infuscated. 



Var. C. Some specimens from Western Australia (Albany. Blount Barker 

 and Darling Ranges) resemble the typical form, but the prothorax is without 

 punctures, except for a few on the margins. One of them in colour resembles 

 the preceding variety, but the others are darker. 



DiTROPinus i;i.,E(iAXTri.fs Haly. 



Only the male of this species, from "Australia," was described by Baly. and 

 his specimen was noted as having ''Body beneath stained with piceous"; I liave 

 only seen one specimen agreeing with this character; on another the under surface, 

 including the pygidium, is entirely red, and cm another the pygidium is red but 

 the rest of the abdomen is black; on all other males the metasternum and ab 

 <lomen, including tlie pygidium. are deep l)lack. altlioiigh (•lotlie<l witli thin wliit"
