530 Mr. Francis P. Pascoe's Notes on 



elevated carina or crest in the mesial line of the disc ; scutellum 

 transverse, greyish ; elytra remotely punctured, slightly concave 

 towards the base, which is marked with a very slight, almost ob- 

 solete ridge, the apex rounded, a large oblique whitish-grey patch 

 behind the middle, not meeting at the suture, and bordered with 

 darker brown than the rest of the elytron ; body beneath with a 

 sparse yellowish-grey pile ; legs with a varied brown and greyish 

 pubescence, mixed with long white hairs. 



Length 4 lines. 



This Niphona will be readily distinguished from the other 

 Australian species by its prothorax. 



2. Niphona oblita. 

 N. nigro-setosa, pube ochracea grisea fuscaque varia ; protho- 



race modice punctato, medio simpliciier convexo ; scutello 



nigro.

Black, closely covered with a brown pile, varied with ochra- 

 ceous and a little grey, mingled with a few black setaceous hairs ; 

 head with an impressed line between the antennae, not on the 

 vertex ; antennae varied with brown and grey ; prothorax regu- 

 larly convex, a brown, nearly naked mesial stripe Vifitli small 

 punctures, on each side two ochraceous stripes, between which is 

 a grey stripe spotted with black ; scutellum transverse, entirely 

 black ; elytra coarsely punctured, simply convex at the base, the 

 apex truncate, or rather sub-sinuate, the outer angle slightly pro- 

 jecting, dark-brown, with little patches of ochraceous and grey, 

 the latter at the middle forming an oblique, indistinct patch ; body 

 beneath with a coarse, greyish pile ; legs with a greyish-mottled 

 pubescence, the tarsi nearly black. 



Length 4 lines. 



Has a general resemblance to the last species, but the prothorax 

 is without the crest, and the greyish elytral patch — which is so 

 general in one form or another in this genus — is more central. 

 The other two Australian species {N. Bakewellii and N. irata) 

 may be distinguished, inter alia, by having no stripes on the 

 prothorax.
