 antice et externe bidentatis.

 This species is entirely of a shining black, with perhaps a very 

 slight bronzy lustre. The head is drooping, the face being at right 

 angles to the body. The facial grooves are very short and paral- 

 lel. The thorax is longer than broad, rather convex, truncate in 

 front, and rather rounded at the posterior angles, with the base 

 broadly margined and reflexed, and the dorsal line but slightly 

 marked. The elytra are nearly twice as long as broad, convex, 

 truncate at the base, rounded at the apex, and parallel-sided, with 

 four irregular rows on each of punctured fovete and with the 

 sides and apex coarsely granulated. The fore tiboe are tridentate 

 externally, the apical tooth being formed by a broad extension of 

 the apex of the joint, while the other two are small and situated 

 in the middle of the joint ; there are also two or three small 

 teeth on the anterior surface of the tibiae near the middle. The 

 mandibles are blunt at the apex. The maxillary palpi have the 

 last joint triangular, while the labial are strongly securiform. 



I have no addition to make to the genus Gerntoglossa at 

 present, and I find myself compelled again to defer any attempt 

 to describe the Australian species of Clivina. M. Putzeys, it ap- 

 pears, has lately described four species of Australian Olivince, 

 under the names of G. suturalis, planicejps, elegans, and atrcda, 

 and until I can procure his descriptions of these species or can 

 ascertain to what insects they refer, it would be obviously use- 

 less for me to meddle with the genus at all. I am enabled, 

 however, to describe one species of Dyschirius, as I am aware 

 that no Australian species of that genus has hitherto been 

 known.
