CORRHENES. 



C. pauxilla, sp. no v. Picea plus minusve rufescens ; pilis subtili- 

 bus erectis sat crebre instructs et pube grisea vestita, hac 

 pube fusca et albida intermixta ; antennis minus robustis, 

 quam corpus vix brevioribus, articulis singulis pube pallide 

 fusca albidaque confuse variegatis, articulo 3° quam V' sat 

 longiori ; oculis sat fortiter granulatis ; prothorace parum 

 transverso, supra sat sequali (longitudinaliter obsolete 

 carinato), lateribus antice dente perspicuo armatis ; elytris 

 sat crebre sat fortiter punctulatis, ad apicem rotundatis.

This species differs in some structural characters from C. paulltty 

 Germ, (the type of Corrhenes), but I cannot ascertain that any 

 other genus has been founded in which it could be placed and its 

 divergence from Corrhenes is scarcely sufficient to justify making 

 it the type of a new genus. Its antennae are evidently less robust 

 than those of C. paidla, its eyes are more strongly granulate, and 

 the lateral tubercles of its prothorax (though sinailarly situated) 

 are notably better defined. 



Unfortunately the descriptions of nearly all the Australian 

 species attributed to Corrhenes are of the slightest and most un- 

 satisfactory kind and there is comparatively little in them except 

 loose diagnoses of colour and markings. As, however, these seem 

 to be but little subject to variety (judged by C. paiilla, Germ., — 

 the only CorrJienea of which I have seen numerous examples) it 

 is perhaps fairly safe to assume that a Corrhenes differing mar- 

 kedly in these respects from all previous descriptions is a good 

 new species. 



The present insect is covered on the upper surface with close 

 and somewhat coarse pale brown pubescence variegated with dark 

 brown and whitish. The dark brown pubescence forms a line 

 running backward from the inner margin of each eye and con- 

 tinued on the pronotum to about its middle, the two lines being 

 curved in such fashion as almost to meet on the front margin of 

 the pronotum ; the dark pubescence also forms a large ill-defined 

 common blotch behind the scutellum. The whitish pubescence is 

 chiefly along the base of the elytra, along the middle part of the 

 suture, and (somewhat behind the middle) on the disc of the 

 elytra where it forms a somewhat wide fascia (with its front and 

 hind margins strongly zigzagged) running obliquely forward from 

 the lateral margin but not reaching the suture. This fascia is 

 much more sharply defined in some examples than in others. 

 The under surface is uniformly covered with pubescence of a 

 whitish brown colour. The antennre femora tibiae and tarsi are 

 variegated with dark and light brown pubescence.
