Descriptions of hitherto nncharaderized Andmlian Phytophaga ; 

 by Joseph S. Baly, F.L.S., &c. 



The present paper contains the descriptions of some interest- 

 ing Australian Insects recently added to my collection, the 

 greater number of which were collected in Western Australia hy 

 Mr. Duboulay. 



Duhoulaia favipennis, 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 otlier sex. 



Duhoulaia fulva, n. sp. 

 Elongata, subcylindrica, fulva, nitida, subtus pube adpressa 

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

 tate, medio vitta obsoleta instructo ; elytris parallelis, sub-crebre 

 punctatis, utrisque vittis quatuor impunctatis instructis. Long. 

 6h lin. 



*'Hab. Western Australia ; a single specimen collected by Mr. 

 Duboulay. 



Head coarsely punctured, sparingly clothed with adpressed 

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

 the face. Thorax slightly longer than broad, sub-cordate, some- 

 what closely punctured, on the middle of the disk is an impunc- 

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

 the basal half. ScuteUum semi-ovate, pale piceous. Elytra 

 broader than the thorax, their surface more finely and less 

 closely punctured than the latter; each with four impunctate 

 vitta3, abbreviated near the apex and not raised above the general 

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

 a single sulcate stria. Hinder thighs thickened, armed beneath 

 near the apex with a short tooth.
