of the abdomen finely and thieklj puneturcd ; legs pitchy ; 

 antenna ferruginous, scarcely extending to the middle of the 

 prothorax. Length 13 lines. 



A much larger species than P. angulata, but with shorter 

 antenna? proportionally, more nitid, a longer prothorax con- 

 tracted behind, and strongly striated elytra, Avhich are con- 

 siderably broader posteriorly. In the foUownig species the 

 elytra are nearly parallel, and the prothorax has the apex and 

 base of the same breadth. 



Prometh is quadricoUis. 

 P. nigra, subnitida ; prothorace traiisversim subquadrato ; elytris 

 subparallolis, punctato-striatis, interstitiis niodice convexis.

Resembles the last, but with head and prothorax much less 

 finely punctured, the latter very much more transverse, not 

 narrower at the base, slightly canaliculate ; elytra nearly pa- 

 rallel at the sides, punctate-striate, the stria broad and shal- 

 low, the punctures large, intervals of the stria moderately 

 convex ; abdomen very minutely punctm-ed, the second and 

 third segments with a series of short longitudinal ridges at the 

 base. Length 9 lines. 



It will be necessary to form a new genus for the reception 

 of Upis cylindrica^ Germ.*, which, as M. Lacordaire justly 

 observes, is more related to ^feneJ)In'h(s than to U2)is. It is a 

 very distinct form, for which I propose the name of 



(ECTOSIS. 

 Ocidi angustati, infra acuti. 

 Prothorax angulis posticis rotundatis. 

 Eiiipleura postice defccta. 



It is a less depressed form than MenepMlus, and has on each 

 side between the base of the mandible and the eye a prominent 

 fold, as in Ij)/ithimus • and it is this apparently which gives the 

 latter its peculiar form. The prosternum is recurved behind, 

 and temiinates in a short triangular process. Tlie absence of 

 the epiploura towards the apex is also characteristic of Dechius, 

 Pascf, another Australian genus of this subfamily, but which 

 is notwithstanding more allied to Tenehrio^ as it appears to 

 me, on account of its spurred tibia. My specimen is from the 

 Darling River.

t Jouni. of Entom. ii. p. 4oo. Mr. F. liates (Trans. Ent. Soc. 1868, 

 p. 2<>o) contradicts my statement a^ to the absence of the hook on the 

 mtenial maxillaiy lobe of Pcchiu-<i aphodioidi-s. This part has since been 

 examined by Messrs. Smith and C. AVaterhouse, of the British Museum, 

 who agree with me that it does not possess a vestige of such a peculiarity.
