144 Mr. F. P. Pascoe on new Genera and Species of 



large, strongly securiform ; the labial short, thick, approximate 

 at the base. Prothorax transverse, convex, apex rather slightly 

 emarginate, sides rounded but broadly emarginate at the pos- 

 terior angle, the emargination with a tooth in the middle. 

 Elytra ovate, convex, the shoulders rounded 5 epipleura broad 

 at the base, gradually narrower and almost obsolete at the 

 apex. Femora strongly clavate ; anterior tibise toothed along 

 the outer margin, gradually thicker below, the apex obliquely 

 truncate and terminating in a stout spur inwardly, the inter- 

 mediate and posterior linear, the edges round their cotyloid 

 cavities spinous ; tarsi slender, setose beneath ; the basal joint 

 of the posterior moderately elongate. Prostemum abruptly 

 elevated, rounded anteriorly and posteriorly. Mesosternum 

 abrupt and a little excavated in front. Metasternum very 

 short. Abdomen with the third and fourth segments mem- 

 branous at their edges. Body, with the legs and antennae, 

 covered with long flying hairs. 



After Dr. Leconte, I have taken Amphidora as the type of 

 a subfamily perfectly distinct from the Adeliinse, in which 

 M. Lacordaire places it, although with some doubt. The sub- 

 family forms t© a certain extent an exception to the cognate 

 groups in regard to the tarsi, the pubescence beneath being 

 " very coarse, sometimes almost spinous ;" in Ectycjie it is 

 completely setose (or spinous). The Amphidorinae hitherto 

 have been exclusively Californian and Chilian ; and, notwith- 

 standing there are so many points of agreement between the 

 latter and the Australian beetle-faunas, it was not until after 

 a long examination that I ventured to consider this genus one 

 of its members. All the essential characters, however, are 

 the same, the intercoxal process, very broad in Amphidora it- 

 self, is considerably less so in Stenotrichus, and we have seen 

 that the vestiture of the tarsi is variable. 



I owe my specimen to the Rev. George Bostock, of Free- 

 mantle.

Black, opaque, everywhere above covered with long, erect, 

 slender, black hairs ; head, upper lip, and prothorax closely 

 and finely punctured ; scutellum minute, punctiform ; elytra 

 about three times the length of the prothorax, striate-punctate, 

 the intervals closely and rugosely punctured ; breast gla- 

 brous, closely punctured ; abdomen coarsely punctured, hairy. 

 Length 2 lines.
