194 Mr. G. C. Champion on 



Hab. Queensland, Moreton Bay. 



I have seen six specimens of this species : the type, a 

 similarly-coloured castaneous 2 from " Queensland," and 

 four from Moreton Bay (^ in Mus. Oxon., <?c£9 in Mus. 

 Brit.), almost wholly black. The sexes differ like those 

 of Egestria taeniata, except that the apical joint of the 

 <£ antenna is much more elongate in D. comata. Pascoe's 

 rough figure gives no idea of the very coarse puncturing 

 of the upper surface, the punctures on the head and pro- 

 thorax being rounded and umbilicate. The length varies 

 from 7|— 11 mm. 



Egestria, Pascoe. 



The type of this genus is E. taeniata, the second species, 

 E. suturalis, Pasc, the two sexes of which are now known, 

 having the terminal joint of the antennae very little longer 

 than the tenth. Both have a long, cultriform apical joint 

 to the maxillary palpi, the only character separating them 

 from Diacalla, the supposed differences in the form of the 

 intercoxal process of the abdomen having no real existence. 

 E. hirticollis and rubicunda, Macl., as stated above, are 

 certainly referable to Ictistygna, Pasc, which has the 

 anterior coxal cavities closed behind by the inward exten- 

 sion of the prothoracic epimera ; E. albilineata, Carter, and 

 E. sulcicollis, Blackb., are also here transferred to other 

 genera. In both species of Egestria, but more distinctly 

 so in E. suturalis, the inferior basal margin of the pro- 

 thorax is seen to be complete, when the prothorax is 

 completely detached.

Hab. Queensland, Rockhampton, Peak Downs, Gawler. 



A variable insect, the males averaging much smaller 

 than the females and having the elytra narrowed from 

 the base. The oblique stripe of pallid pubescence on each 

 elytron, which is usually confluent with the one on the 

 opposite wing-case before the apex, varies in development ;
