Hab. South Australia: Oodnadatta, Quorn (Blackburn's collection). Type, 



I. 



On the male there is a small and slight infuscation, starting at the suture, 

 at the apical third of the elytra ; on the female the infuscation is extended so as 

 to occupy the whole of the apical third; the female also has some feeble pro- 

 thoracic infuscations. The distance between the eyes of the female is slightly 

 less than the greatest width of the clypeus, and slightly more than in the male. 

 In some respects the species is close to the description of D. obtusus, but the head 

 is dark at the base, and the elytra are without distinct punctures on the interstices ; 

 their seriate punctures are rather small, but, owing to waterlogging, they appear 

 to be as wide as the interstices on the male, and almost as wide on the female, 

 their true sizes are apparent from oljlique directions. It approaches some of the 

 smaller and narrower forms of D. dcwisi, but the intercoxal process of the pro- 

 sternum is much less conspicuously notched, being in fact almost truncated ; from 

 the smaller specimens of D. scrcnits, to some of which it is very close in appear- 

 ance, it may be distinguished by the eyes; those of the male being scarcely as 

 close together as those of the female of that species ; the prothoracic punctures, 

 although small, are also more distinct. 



DITROPIDUS APICIPENNIS sp. nov. 



d Reddish flavous ; scutellum, extreme base, shoulders, suture and apical 

 half (or lessj of elytra, abdomen and part of metasternum black; club, tarsi, 

 middle knees, and almost the entire hind legs, more or less deeply infuscated, or 

 blackish, linder-surface and legs sparsely clothed. 



Head with fairly dense, sharply defined, but asperate punctures; median line 

 slightly impressed. Eyes widely separated. Protlwra.v more than twice as wide 

 as the median length; with very small, dense punctures. Elytra at base slightly 

 wider than long, sides obliquely narrowed to apex; with series of small punc- 

 tures, becoming larger and set in distinct striae at the sides ; interstices with very 

 minute punctures, the outer one on each elytron dilated at the apex, and not 

 continuing the general convexity. Front tibiae slightly longer and thinner than 

 the hind ones. Length { d ? ), 3 '25-4 mm.

.\n unusually wide species, the specimens of which at one time I was inclined 

 to regard as representing a large, wide, and distinct variety of D. davisi, but the 

 elytral tips are essentially ditiferent, the marginal interstice of each being dilated
