CoTXJLADEs [Tenebiionidae]. 



Head subquadrate, exserted, but not constricted behind. Eyes small, 

 lateral, round. Antenna) subnioniliforni, short, thick, veiy hairy, the 

 basal joint longest, the rest to the tenth subequal, very transverse, 

 the eleventh smaller, truncate. Labrum small, rounded anteriorly and 

 ciliated. Mentmii subquadrate, produced at the sides. Labium trans- 

 verse, rounded in front. l*alpi short, clavate, tenninal joint ovate. 

 Prothorax subquadrate, wider anteriorly. Elytra ovate, convex. Legs 

 short; all the tarsal joints, except the last, very short. 



To this genus belongs the Tagenia leucospila of Mr. Hope ; the 

 head, however, not contracted behind into a neck, and other cha- 

 racters show that it is veiy distinct from Tac/enia ^Stenosis'] ; at 

 the same time it is difficult to point out a nearer ally. In this and 

 the following genus the intermediate legs appear to be without 

 trochanters. 



Cotidades fascicularis. (PI. YII. fig. 5.) 



C. niger, rugoso-punctatus ; elytris obsolete albo-fascicidatis. 



Hah. Australia (Melbourne). 



Dull brownish-black ; head and prothorax covered with large, coarse, 

 nearly confluent pmictiu-es, and sparingly furnished with stift', decum- 

 bent, scaly hairs; elytra coarsely striato-pimctate, each with three 

 indistinct ridges and with eight to ten short fascicles of brownish- 

 white hairs, indeterminately arranged, but sometimes nearly wanting 

 (fi'om abrasion ?) ; claws pale ferruginous ; body beneath strongly 

 punctured. Length 3 lines. 



Elascfs [Tenebrionidae]. 



Head rather elongate, scarcely exserted. Eyes small, lateral, undivided. 

 Antennae short, hairy, eleven-jointed, the first longest, the rest trans- 

 verse and more or less equal, except that the last is smaller than the 

 preceding one. Palpi moderate, filiform, the tenninal joint ovate, sub- 

 acuminate. Mentum transverse, the angles roimded. Labium small, 

 transverse. Prothorax subquadi-ate, irregidar, much broader than the 

 head, projecting in front, and lobed posteriorly, slightly dilated and 

 seiTated at the sides. Scutellum very small, quadrate. Elytra nearly 

 parallel, broader than the prothorax. Leg-s short ; femora and tibiae 

 compressed, the latter ciliated externally ; tarsi very short and slender, 

 the last joint nearly as long as the rest together. 



This genus is not very fiir removed from the last ; and, judging
