124 Mr. F. P. Pascoc on some neiv or little-known 



quadrate. Labium very transverse. Prothorax narrower than the 

 elytra, transverse, sinuated anteiiorly, its surface regular. Elytra 

 rather long, slightly rounded at the sides. Legs moderate ; tibia) bi- 

 calcarate, ciliated externally ; tarsi slender. 



Allied to Ulodes, Er., which differs in the following points. In 

 Ulodes the head is short, not being prolonged below the eyes ; the 

 joints of the antennae are subequal and transverse, surrounded by a 

 dense whorl of squamose hairs ; the surface of the prothorax is very 

 irregular ; the elytra are short, and the body generally is covered 

 with short crisp scales. To Ulodes I refer Bolitophagus Sa/phira, 

 Newm., and Endopldoms variicornis, Hope. My genus Byrsax {ante, 

 p. 42) is also a member of this group of Tenebrionida) (Bolitopha- 

 ginae) : it is true I cannot quite satisfy myself that it is hetero- 

 merous, but I have no doubt a minute basal joint exists ; and in 

 other respects it appears to be congeneric with Diaperis horrida, 01. 

 (Asida liorrida, Walk.). Trox comutus, Fab., is also referable to 

 Byrsax. 



Dipsaconia Bakewellii. (PI. VII. fig. 6.) 



I), elliptico-ovata, pilosa, fulvo-brunnea ; elytris nigro-variegatis. 



Hub. Australia (Melbourne). 



Elliptic-ovate, brownish-fulvous, covered with short decumbent 

 hairs, among which others longer, nearly erect and slightly curved, are 

 interspersed ; prothorax nearly as wide as the elytra at the base ; scu- 

 tellum rather indistinct, subtriangular ; elytra nearly parallel at the 

 sides, rounded at the apex, striato-punctate, each with three costae, and 

 varied with four or five dull-black band-like marks ; antennae brown ; 

 body beneath ferruginous-brown, very sparingly pubescent. Length 3| 

 lines. 



In this and the following species, both of which we owe to Mr. 

 Bakewell's researches, may be noticed, in certain lights, a glowing 

 fiery-red tubercle at the bottom of each elytral puncture. 



Dipsaconia pyritosa. 



D. elongato-ovata, hirta, rufo-fusca; prothorace elytrisque nigro-varie- 

 gatis. 



Hub. Australia (Melbourne). 



Elongate-ovate, reddish-brown, closely covered with short, thick, 

 strongly hooked hairs ; prothorax narrower than the elytra at the base, 

 the disc with a large irregular blackish patch ; scutellum indistinct, 

 subquadrate ; elytra rather broader behind, striato-punctate, marked 

 with several irregular, dull brownish-black patches ; antennae brown ; 

 body beneath and legs ferruginous-brown, sparingly pubescent. Length 

 3J lines.
