Genus A M p a g i a Pascoe, Trans. Ent. 8oc. Lond., 1870, p. 208. 



Head partially concealed by prothorax. Rostrum short, 

 straight, wide and flat. Antennfe short and stout; club briefly 

 ovate, less than half the length of funicle. Prothorax more or 

 less conical. Scutellum absent.* Elytra closely applied to pro- 

 thorax, sides regularly decreasing in width to apex. Pectoral 

 canal deep and wide. Mesosternal receptacle strongly raised, 

 narrow, curved, emargination transverse ; cavernous. Meta- 

 sternum shorter than following segment, its episterna concealed 

 except posteriorly. Uasal segment of abdomen large, its disc 

 flattened . and masked outwardly by a subcircular rim or ridge. 

 Leys long; femora angular, compressed, edentate, widely grooved, 

 posterior suboblong, angularly produced on their outer upper 

 edge. Elliptic, strongly convex, squamose,! apterous.* 



Mr. Pascoe founded this genus on a weevil from King George's 

 Sound, having very remarkable femora and abdomen. Sub- 

 sequently,! he described a second species (/I. rudis) from New 

 Zealand, referring it to a new genus {Acallojiais) which he com- 

 pared with Acalles, a genus with which, other than in density of 

 clothing, it has scarcely anything in common. Comparing M r. 

 Pascoe's two species together, (I do not know Major Broun's 

 A. sctdpturatus) it will be seen that both A. erinacea and A. 

 rudis agree in the mesosternal receptacle, abdomen, legs, eyes, 

 rostrum, antennae, and, in fact, in all characters on which genera 

 are founded. In the Memoirs of the Australian Museum, Mr. 

 Olliff, in dealing with the insects from Lord Howe Island, 

 described another species, A. montlgava, i-ef erring it, however, to 

 Idotd.sia, to the species of which genus it bears a very strong super- 

 ficial resemblance; a second species, referred by him to Idotasia, 

 possibly belongs to Ampagia; unfortunately, I omitted to examine 

 the type when last in Sydney, but Mr. Olliff describes the femora 

 as "strongly thickened." It is certainly not an Idotasia. Cryp- 

 torhynchus femoralis Erichs., is also an Ampagia. Of the two 

 new species described below, I have not ventured to regard A. 

 alata as belonging to a new genus, despite its possession of
