34 Mr. F. P. Pascoe on new Genera and SjMcies of 



third segments with a series of sliort longitudinal ridges at the 

 base. Length 9 lines. 



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

 of Uj)is ci/Iindrica, Germ.*, which, as M. Lacordaire justly 

 observes, is more related to Menej)hUus than to Upis. It is a 

 very distinct form, for which I propose the name of 



(ECTOSIS. 



OcuU angustati, infra acuti. 

 Protliorax anguhs posticis rotundatis. 

 E^ipleura postice defecta. 



It is a less depressed form than Menejylulus^ and has on each 

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

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

 latter its peculiar form. The prosternum is recm-ved behind, 

 and terminates in a short triangular process. The absence of 

 the epipleura towards the apex is also characteristic oi Decliius^ 

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

 is notwithstanding more allied to Tenehrio^ as it appears to 

 me, on accoimt of its spuiTcd tibiae. My specimen is from the 

 Darling River. 



Meneristes. 



Subfamily Texebeioxix^. 

 Tibice calcaratae ; femora incrassata. 



This genus differs only in the above characters from Mene- 

 jjJu'Ius, Muls. The type I have received from Dr. Howitt, 

 under the name of " Baryscelis laticollis^ Boisd." That genus 

 was never published ; but, according to a note of M. Lacor- 

 daire's, it belongs to the Coelometopinte, and therefore cannot 

 be this. In the British Museum the same species is labelled 

 '^ Tenehrio australis^ M^L. (Boisd.)." The descriptions of 

 Dr. Boisduval in the ' Voyage de I'Asti-olabe ' are very short, 

 varying from five Latin words to five-and-twent}^, the latter 

 exceptional ; and these are followed by a strictly literal French 

 translation. AYith the vague ideas of genera common thirty 

 years ago, and even later, the generic name affords scarcely 

 any clue, and it is only by a sort of tradition that we are able

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

 p. 205) contradicts my statement as to the absence of the hook on the 

 internal maxillary lobe oi 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 yestige of such a peculiarity.
