of the abdomen finely and thickly punctured ; legs pitchy ; 

 antennas ferruginous, scarcely extending to the middle of the 

 prothorax. Length 13 lines. 



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

 antennse proportionally, more nitid, a longer prothorax con- 

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

 siderably broader posteriorly. In the following species the 

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

 base of the same breadth. 



Pro meth is quadrico His . 

 P. nigra, subnitida ; prothorace transversim subquadrato ; elytris 

 subparallclis, punctato-striatis, interstitiis modice convexis. 



Hob. Swan River. 



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 striae broad and shal- 

 low, the punctures large, intervals of the strias moderately 

 convex • abdomen very minutely punctured, 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 cylindrical Germ.*, which, as M. Lacordaire justly 

 observes, is more related to Menephilus than to Upis. It is a 

 very distinct form, for which I propose the name of 



(Ectosis. 



Oculi angustati, infra acuti. 

 Prothorax angulis posticis rotundatis. 

 Epipleara postice defecta. 



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

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

 fold, as in Ipltthimus ; and it is this apparently which gives the 

 latter its peculiar form. The presternum is recurved behind, 

 and terminates in a short triangular process. The absence of 

 the epipleura towards the apex is also characteristic of Dechius, 

 Pasc.f, another Australian genus of this subfamily, but which 

 is notwithstanding more allied to Tenebrio, as it appears to 

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

 Darling River.

t Journ. of Entom. ii. p. 455. Mr. F. Rates (Trans. Ent. Soc. 1868, 

 p. 265) contradicts my statement as to the absence of the hook on the 

 internal maxillary lobe of Dechim aphodioides. This part has since been 

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

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