moderately rounded and much wider at base than at apex, 

 margins rather wide ; with numerous small punctures on disc, 

 becoming somewhat larger on sides, and asperate on margins. 

 Elytra slightly wider than base of prothorax, almost parallel- 

 sided to near apex ; punctures and interstices irregular. 

 Under-surface feebly shagreened. Flanks of prosternum finely 

 wrinkled. Abdomen lightly upcurved at middle of apex. 

 Front femora acutely dentate. Length, 7J-8 mm. 



Hah. — Western Australia: Cue (H. W. Brown). Type, 

 I. 3409. 



The prothorax has the sides more rounded and less 

 conspicuously dilated to base than on the preceding species, 

 and the front angles are more acutely produced ; and the front 

 edge of the medisternum is less conspicuously elevated and but 

 feebly undulated, instead of distinctly notched, where it joins 

 each episternum. The elytra appear to be very minutely 

 wrinkled all over, their punctures are of moderate size (slightly 

 larger than on the preceding species), and in places are in 

 feeble semi-double rows, becoming single posteriorly, but they 

 are mostly dense and irregular, from behind the shoulders 

 along the middle to about the apical third they are frequently 

 transversely or irregularly confluent ; some of the interstices 

 are feebly traceable to base, and they are more distinct on the 

 apical slope than elsewhere. The basal joint of each tarsus 

 is moderately large, but as they are alike on all six the two 

 specimens in the Museum would appear to be females ; one 

 of them has the fourth segment of abdomen depressed in 

 middle, but this appears to be due to irregular contraction. 



Trypocolaspis, n. g. 



Eyes large, rather coarsely faceted, lightly notched behind 

 antennae. Clypeus widely transverse, not separated from 

 head by a distinct suture. Labrum short, feebly notched in 

 front. Antennae long. Prothorax strongly transverse, base, 

 apex, and sides narrowly margined, sides evenly rounded in 

 middle. Scutellum small. £'///^r« not much longer than wide, 

 closely applied to and very little wider than prothorax, each 

 (across middle) with about twenty rows of fairly large punc- 

 tures of almost even size throughout, and nowhere transversely 

 confluent. Prosternum with medisternum wide, front por- 

 tions very narrow in front of coxae ; episternum on each side 

 with front margin wide, oblique, and almost straight, lateral 

 suture deep. Metasternum short. Abdomen with basal 

 segment (along middle) at least as long as two following 

 combined. Legs short ; femora edentate; tibiae longitudinally 

 canaliculate, somewhat dilated at apex ; the four hind ones 

 not notched near outer apex : claws appendiculate.
