much coarser prothoracic punctures. It is rather more 

 elongate than lentulus, the prothoracic punctures decidedly 

 coarser, the sides substrigose, legs brighter, etc. In 

 appearance some specimens are close to females of elegantulus, 

 but are longer, prothorax with more conspicuous punctures, 

 etc. The female is usually more coppery than the male, but 

 occasionally is greenish-blue, or bluish-green ; the hind femora 

 are usually infuscated at the base, but on several specimens 

 from Forest Reefs they are infuscated almost throughout. 

 From some directions the median line of the head appears 

 to dilate to a wide fovea, but it is really shallow throughout. 



DlTROPIDUS ALBICEPS, n. Sp. 



c . Coppery, sometimes with a slight purplish gloss; 

 labrum, antennae (tips of the joints of the club infuscated), 

 palpi and legs (claws infuscated) flavous, or reddish-flavous. 

 Head and sides of metasternum densely clothed with white 

 pubescence, rest of under-surface and legs more sparsely 

 clothed. 



Read shagreened and with dense but more or less 

 concealed punctures; median line feeble. Eyes rather widely 

 separated. Antennae somewhat longer than usual in genus. 

 Prothorax more than twice as wide as the median length; 

 with dense and small punctures, the sides very densely and 

 finely strigose. Elifira suboblong; with rows of punctures of 

 moderate size, becoming larger and set in deep striae on the 

 sides, interstices slightly shagreened. Ltg& stout but not very 

 long. Length (d, 9), 2'75-3-25 mm. 



9 . Differs in being more robust, head less densely 

 clothed (and in consequence with the punctures and median 

 line more distinct), eyes more distant, club and legs thinner, 

 elytra less narrowed posteriorly^ and abdomen larger, with 

 a large, round, deep, apical fovea. 



Hah. — South Australia: Oodnadatta (Blackburn's collec- 

 tion). Type, I. 10990. 



Allied to the preceding species, but elytra slightly less 

 oblong, head, especially of male, more conspicuously clothed 

 (so that it appears quite white), eyes less distant, prothorax 

 with much smaller punctures, its sides more closely strigose 

 (causing the surface there to appear almost shagreened), 

 elytra slightly shagreened, and legs paler. It is apparently 

 close to the description of co^tafua, but although the 

 prothoracic punctures are dense they could not be regarded 

 as coarse, the elytra also have three, instead of two interstices 

 costate on each side, the head is densely clothed, and only 

 the tips of the joints of the club are infuscated. It is
