The present paper contains the descriptions of some interest- 

 ing Anstralian Insects recently added to my collection, the 

 greater number of which were collected in Western iVustralia ]»y 

 Mr. Duhoulay. 



DiihouJaia fldvipennix, mihi. 



Since the publication of my description of this insect, I have 

 obtained a specimen of the ^ sex ; it is only one third the size 

 of the ^, (Long. 5 lin.), the thorax is slightly broader, the last 

 segment of the abdomen has its apical margin produced into a 

 short obtuse lobe, the surface of which is depressed and concave, 

 and the hinder thighs are more incrassate ; in all other respects 

 it agrees with the other sex. 



DuliDiilditi fiilvii^ u. .^p. 



Elongata, subcylindrica, fulva, nitida, subtus pube adpressa 

 dense vestita, supra glabra; thorace subcordato, sub-crebre punc- 

 tato, medio vitta obsoleta instructo ; elytris i)arallelis, sub-crebre 

 punetatis, utris(|ue vittis quatuor impunctatis instructis. Long. 

 6h lin. 



Hal). W(^stern Australia ; a single specimen collected by Mr. 

 Duboulay. 



Head coarsely punctured, sparingly clothed with ad])ressed 

 hairs; clypeus depressed, wedge-shaiied, distinctly separated from 

 the face. Thorax slightly longer than l)road, sub-cordate, some- 

 what closely punctured, on the middle of the disk is an im])unc- 

 tate, ill defined vitta, most distinct, and slightly raised on 

 the basal half. Scutidlum semi-ovate, pale ])iceous. Elytra 

 broader than the thorax, their surface more finely and less 

 closely punctureil than the latter; each with four imi)unctate 

 vittie, abbreviated near the apex and not raised above the general 

 surface of the disk ; running parallel and close to the siiture is 

 a single sulcat*^ stria. Hinder thighs thic-kened, armed bencatli 

 near the ap(^x with a short tootli.
