Subfamily CRYPTORHYNCHIDES. 



The new genera proposed here are all more or less closely 

 allied to Poropterus. 



Neodecilaus, n. g. 



Head large, convex, not at all concealed. Eyes de- 

 pressed, almost circular, finely faceted. Rostrum moder- 

 ately long and wide, curved ; with a shallow groove on each 

 side above scrobe. Antennae rather stout ; scape inserted nearer 

 base than apex of rostrum and shorter than funicle ; basal 

 joint of the latter elongate ; club ovate, subcontinuous with 

 funicle. Prothorax transverse, sides moderately rounded, base 

 very feebly bisinuate, constriction absent, ocular lobes obtuse. 

 Scutellum absent. Elytra subovate, outline almost con- 

 tinuous with that of prothorax. Pectoral canal moderately 

 deep and wide, terminated between intermediate coxae. 

 Mezosternal receptacle feebly raised, walls equal through- 

 out, emargination semicircular; slightly cavernous. 

 M etasternum less than half the length of the following 

 segment: episterna narrow. Abdomen large, sutures dis- 

 tinct; two basal segments large, first not much longer than 

 second, its apex incurved, intercoxal process moderately wide; 

 third and fourth combined the length of fifth and slightly 

 shorter than second. Legs rather short; posterior coxae not 

 touching elytra ; femora sublinear, edentate, not grooved ; 

 posterior terminated before apex of abdomen ; tibiae rather 

 short, third joint wide and deeply bilobed. Ovate, convex, 

 squamose, non-tuberculate, apterous. 



The mesosternal receptacle appears to be truly open, but 

 on probing it is felt to be slightly cavernous. The genus is 

 allied to Decilaua, from which it may be readily dis- 

 tinguished by the finely-faceted eyes. It appears also to be 

 allied to Coptomerux, but in that genus the posterior femora 

 are said to be dentate. In general appearance both the 

 species described below resemble the members of Aonychus, 

 but the tarsi, metasternum, rostrum, etc., are utterly differ- 

 ent. The sexes are easily distinguished; the <S has the 

 rostrum clothed almost to apex, whilst in the 9 it is shining 

 and clothed only on each side at base ; the eyes also are rather 

 larger in the rf than in the 9 • 



Clothing black and white picus, n. sp. 



Clothing of various shades of grey gratus, n. sp. 



Neodecilaus picus, n. sp. 



Blackish-brown, antennae and tarsi somewhat paler. 

 Closely covered with black scales, a stouter one in each elytral 

 puncture : almost snowy-white scales condensed into small
