white from a fine toment; this is also the case with the 

 two obliquely placed oval spaces on the pygidium. Meta- 

 sternum is deeply excised at the posterior margin; the pro- 

 cess of the first ventral segment is rounded at the apex and 

 has a slight median impression. The front tibise are bidentate 

 in the male, tridentate in the female; the hind femora and 

 tibiae densely covered by very long yellow-whitish hairs. 



Length 14—16 mm. Breadth 6 — 8 mm. 



I have obtained 24 specimens — all showing the same 

 colour and markings — at Xoonkanbah in the interiör of the 

 Kimberley District, in December 1910. 



11. Diapliouia dorsalis Don. — 2 specimens from Cairns, 

 April 1913. 



12. Diaplionia gulosa Jans.(?) — I have before me four 

 specimens of a Diaphonia, two of them are light brown, with 

 some dark markings, two are black with prothorax and the 

 ventral segments partly lighter. It is certainly closely related 

 to the species xanthopyga Germ. and gulosa Jans. Prelimin- 

 ary I class them with the latter. 



The four specimens were all caught in the same locality 

 and on the same day. The front of the head, between the 

 eyes and the sternum, are densely covered with long yellow 

 hairs. In the two lighter- coloured specimens the posterior parts 

 of the head are marked with dark spaces, prothorax (and 

 elytra) has the markings shown in fig. 3, there is also as in 

 D. xanthopyga Germ. a small, indistinct, dark spöt to be found 

 close to each börder slightly in advance of the middle; its 

 sides are densely and coarsely punctured, but the centre more 

 smooth. The elytra are sligtly depressed behind the scutel- 

 lum, the punctures here and there arranged in indistinct rows, 

 externally they are marked with irregular transverse wrink- 

 les; the sutural stria is continued on the side of the scutel- 

 lum but terminates before reaching its base; the scutellum is 

 distinctly punctured, black at the tip and with a more or less 

 distinct median line, the pygidium has a small fovea on each 

 side, a central f-shaped, and two smaller, black spöts on 

 each side, on the ventral side there are some dark markings 

 on the side of the abdominal segment, and some more or less 

 indistinctly defined dark patches on the sternum; the meso-
