basal two-fifths with concealed sculpture, elsewhere with dense 

 and clearly-defined although rather small punctures. Scape 

 inserted just perceptibly nearer base than apex of rostrum, 

 about half the length of funicle and club combined; first 

 joint of funicle slightly shorter than second. Prothorax 

 slightly longer than wide, base rather strongly bisinuate, apex 

 rather narrow and with a conspicuous median fascicle; with 

 four feeble swellings, supporting fascicles, across middle; 

 punctures concealed. Elytra closely applied to and at base 

 but little wider than prothorax, but distinctly dilated to 

 beyond middle, and then arcuate to apex; with irregular rows 

 of large more or less concealed punctures; third interstice 

 with two large obtuse tubercles : one at basal fourth, the 

 other beyond the middle; second and fifth each with a feeble 

 submedian tubercle, some feeble ones elsewhere, but apices 

 produced as two subconical fasciculated tubercles. Legs long; 

 femora lightly but acutely dentate. Length, 7J-8 mm. 



9 • DijBfers in being larger (8J-9 mm.), rostrum thinner, 

 clothed only about basal fourth, elsewhere shining (it is sub- 

 opaque in the male) and with minute punctures ; the antennae 

 are inserted a trifle nearer to the base of rostrum, and the 

 abdomen is slightly more convex.

Differs from diurus in being smaller, in the apex of pro- 

 thorax produced singly (^8) instead of bifurcate, apices of 

 elytra more acutely produced, and first joint of funicle slightly 

 shorter than second instead of distinctly longer. The sooty 

 patch on the abdomen covers most of the three apical seg- 

 ments, but at the base of the second one it is encroached upon 

 by three conspicuous triangles of paler scales. On the pro- 

 thorax and elytra there are sometimes some small spots of 

 sooty scales. From the sides the elytra appear to slope 

 rapidly upwards to about the basal third, and then to more 

 gradually slope downwards to the apex. The seventh inter- 

 stice, for portion of its length, appears almost like an obtuse 

 carina on some specimens. 



POROPTERELLUS ABDOMINALIS, n. Sp. 



Black ; antennae and tarsi of a rather bright-red ; tibiae 

 and apical margins of elytra reddish. Clothed with muddy- 

 brown or grey scales. , 



Head bald and without punctures, except for a few rather 

 large ones between eyes. Rostrum short and wide, sides 



(38) On one female the apical fascicle of the prothorax is divided 

 down the middle, so as to appear like two narrow, almost conjoined, 

 ones.
