On the abdomen the clothing is very sparse and mostly sooty. 

 There is a distinct tubercle on the third interstice about the 

 middle, marking the summit of the posterior declivity, but 

 elsewhere the tubercles are ill-defined. 



Amorphocis, n. g. 



Head of moderate size, partially concealed from above; 

 forehead evenly convex. Eyes rather small, widely separated, 

 coarsely faceted. Kostrum wide, lightly curved. Antennae 

 thin; scape inserted nearer apex than base of rostrum; two 

 basal joints of funicle elongate; club ovate. Prothorax trans- 

 verse, base truncate, sides strongly narrowed to apex; ocular 

 lobes acute. Scutellum absent. Elytra truncate at base, 

 widest at basal third, thence strongly narrowed to apex. 

 Fectoral canal deep and wide, terminated close to front coxge. 

 Mesosternal receptacle suddenly and strongly elevated, emar- 

 gination feebly curved, hind margin with a perpendicular 

 median ridge ; cavernous. Metasternum about two-thirds the 

 length of the following segment; episterna not traceable. 

 Abdomen fairly large, sutures straight, first segment as long 

 as three following combined, these equal inter se, fifth 

 moderately long. Legs moderately long; femora strongly 

 grooved, tibiae compressed; tarsi wide, third joint deeply 

 bilobed. 



In some respects close to Zenoporopterus, near which, 

 perhaps, it should be placed, but mesosternal receptacle 

 elevated, much as in the allies of Idotasia, second segment of 

 abdomen no longer than third, and metasternal episterna 

 concealed. The typical species has curiously sculptured elytra. 

 Its femora, when viewed from in front, appear to be dentate, 

 but when viewed from behind the front ridge of each is seen 

 to be nowhere dentate, but, at the usual position of a femoral 

 tooth, each has a small fascicle of scales. The four hind tibiae 

 are also peculiarly clothed. 



Amorphocis mtrus, n. sp. 



Black ; upper - surface rather sparsely and irregularly 

 clothed with greyish scales. Abdomen, metasternum, and 

 parts of mesosternum very densely clothed; legs moderately 

 clothed in places, densely in others. 



Head, with dense more or less concealed punctures ; ocular 

 fovea fairly large, and less frontal than is usual. Rostrum 

 about twice and one-half as long as greatest width, sides dis- 

 tinctly incurved to middle, deeply notched on each side of base ; 

 basal three-fourths with rows of large punctures, separated by 

 feeble ridges ; apex with smaller and crowded punctures.
