DITROPIDUS LONGIPES sp. nov. 



(S Flavous, claws and trochanters black, scutellum, extreme base of elytra, 

 and parts of club infuscated. Under-surface and legs with sparse, white pubes- 

 cence, head still more sparsely clothed. 



Head with dense and rather coarse punctures ; median line shallow and rather 

 wide. Eyes very widely separated. Protliora.v at base not quite twice as wide as 

 the median length ; punctures in middle as large as on head, but not so dense, 

 becoming larger and denser on sides. Elytra obliquely narrowed posteriorly.; with 

 rows of fairly large punctures, becoming larger and set in strong striae on the 

 sides, interstices with very minute punctures. Front legs much longer than hind 

 ones. Length ( c? 9 ) . 2 5-3 mm. 



9 Differs in having the prothorax shorter, elytra less narrowed posteriorly, 

 front legs no longer than the hind ones, and in the abdomen. 



Hob. South Australia: Leigh Creek (Blackburn's collection). Type, L 

 10976. 



The general outlines are somewhat as on the preceding species, but the front 

 legs of the male are decidedly longer than on that species, or on any other of the 

 genus before me, their great length is due primarily to the tibiae, but the femora 

 and tibiae are also longer than those of the other legs. The black trochanters 

 and claws give the legs a rather curious appearance. 



A female from Oodnadatta probably belongs to the species, it differs from 

 the typical female in being somewhat larger, and in having the metasternal 

 episterna infuscated. 



DITROPIDUS BASICEPS sp. nov. 



d Flavous ; base of head, scutellum, extreme base and suture of elvtra, 

 metasternum and abdomen black, club infuscated. Under-surface and legs with 

 sparse, white pubescence. 



Head with fairly dense, sharply defined punctures; median line lightly 

 impressed. Eyes rather widely separated. Prothorax at apex about as wide as 

 the median length ; with rather numerous and sharply-defined, but small punc- 

 tures, somewhat denser but scarcely larger on sides than elsewhere. Elytra 

 obliquely narrowed posteriorly : with rows of rather small punctures, becoming 

 large and set in deep striae on the sides : interstices impunctate or almost so. Front 

 Icf/s slightly longer than hind ones. Length ( d $ ). 2 '2^2 -5 mm. 



9 Differs in having the prothorax somewhat shorter, elytra less narrowed 

 posteriorly, front legs no longer than the hind ones, and abdomen with a large 

 apical fovea.
