124 Mr. F. P. Pascoe on some new or Uttle-hioiun 



quadrate. Labiimi very transverse. Prothorax narrower than the 

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

 rather long, slightly rounded at the sides. Legs moderate ; tibiae 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 Saphira, 

 Newm., and Endo^hlosus variicornis, Hope. My genus Byrsax (ante^ 

 p. 42) is also a member of this group of Tenebrionidse (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. 

 {Askla Jiorrida, Walk.). Tro^v cornutus, Fab., is also referable to 

 Byr'SCLV. 



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



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



Hab. 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 j scu- 

 tellum rather indistinct, subtriangular ; elytra nearly parallel at the 

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

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

 body beneath ferruginous-brown, very sparingly pubescent. Length Sp- 

 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. 



Hah. Australia (Melbourne). 



Elongate-ovate, reddish-brown, closely covered -vvith 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 in-egiilar, dull brownish-black patches ; antennae brown ; 

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

 3i lines.
