infuscated. The punctures on the head (including clypeus) 

 and prothorax are also more distinct. On the typical form 

 (14 specimens) the punctures decidedly decrease in size 

 towards the apex of the elytra, and are quite regular in the 

 striae; at the apex between the marginal and submarginal 

 striae the interstice is conspicuously wider than the others, 

 and either impunctate, or with but one or two punctures. 

 On the variety (5 specimens) the interstice there is covered 

 with coarse, crowded punctures, and the whole of the apical 

 portion is more or less coarsely punctured. 



Two specimens from Northern Queensland are rather 

 smaller (7 mmx.) and narrower, with most of the prothorax 

 entirely black, but -the ©lytral markings and apex are as on 

 the variety. A specimen from Charters Towers has markings 

 as on the variety, but the apex of elytra is as on the typical 

 form.. 



Rhyparida flava, Clark. 

 piceitarsis, Blackb. 

 var. pallida, Jac. 



This species is abundant in the Northern Territory and 

 North-west€rn Australia, and there are two in the Macleay 

 Museum from Port Denison, and varies in length from 4 to 6 

 mm. The knees, tips of tibiae, and the tarsi are usually 

 infuscated or black; the abdomen and metasternum are also 

 sometimes black or infuscated. Pallida appears to have been 

 described from specimens (of which there are several (^o) [n 

 the Museum) with entirely pale legs. Mr. Arrow sent a 

 specimen labelled ''New Holl." as flava after comparison with 

 the type; it is simply a fairly large specimen of the species 

 subsequently named piceitarsis by Blackburn. 



Rhyparida punctulata, Blackb. 



This species has eyes decidedly larger than usual, the 

 space between them considerably less than the diameter of 

 an eye (less in the male than in the female), and the front 

 notched in the middle. It is also distinct by the conspicuous 

 punctures of head and prothorax, the elytral punctures 

 strong at the base and small posteriorly, a small acute pro- 

 jection on each front angle of prothorax, and by the 

 dentate hind femora; the tooth is small, but from some 

 directions is quite distinct. 



Two specimens from Melville Island differ from the type, 

 and some co-types, in having the upper-surface black, in 

 places with a vague bluish gloss, and the elytra obscurely
