slightly abraded ; another starved ^ has the elytra broadest 

 behind the middle, a feeble carina on each side between lateral 

 and median tubercles of prothorax (which are scarcely traceable); 

 the two basal segments in both specimens have large distinct 

 punctures — in normal forms they are shallower and almost com- 

 pletely hidden — and the apical is semicircularly impressed at 

 apex. Where a species is so abundant in specimens as the present 

 it is only reasonable to expect to take starved specimens occasion- 

 ally, and that the two specimens here mentioned are starved I am 

 quite satisfied. 



POROPTERUS CAVIROSTRIS, n.Sp. 



Densely clothed with microscopic muddy-green or brown scales, 

 prothorax and elytra with sparse elongate blackish or brown 

 scales; under surface with irregular moderately elongate scales; 

 legs with projecting elongate scales; head and rostrum densely 

 squamose. Ciliation sparse, moderately elongate, feebly traceable 

 with head in position. 



Convex, subcylindric, tubercles small. Head feebly convex; 

 eyes round, coarsely granulate; ocular fovea concealed; rostrum 

 rather long, thick, distinctly curved, parallel to muzzle (which is 

 somewhat concave) with traces of feeble ridges down the middle 

 and sides; scape inserted very slightly in advance of the middle, 

 just passing muzzle; 2nd joint of funicle almost twice the length 

 of 1st, and slightly longer than three following combined, 3rd-7th 

 distinctly longer than wide ; club free, elongate. Prothorax 

 longer than wide, apex produced, rounded, more than half the 

 width of middle, from behind appearing feebly bifurcate; ocular 

 lobes prominent ; constriction deep, very distinct from above ; 

 sides rounded, median carina narrow, distinct at middle, vanish- 

 ing near base and apex; transverse row of tubercles feeble; apex 

 with a feeble ridge on each side ; base and sides with shallow 

 foveas. Elytra a little wider than prothorax, and about twice 

 the length; disc with regular rows of shallow punctures, in front 

 of each of which is a small and distinct granule, sides with deeper 

 punctures and without granules, base with a ridge extending
