impression can be traced there. From above there appears 

 to be a feeble granule on each side of the prothorax near the 

 base, but from the side this is seen to be due to a rather 

 deep impression. 



Apion convexipenne, n. sp. 



Black, somewhat shining. 



Head with two almost imperceptible grooves between 

 eyes. Rostrum about once and one-half the length of pro- 

 thorax, rather thin, moderately curved, very feebly decreas- 

 ing in width from base to apex ; punctures very indistinct. 

 Antennae inserted about two-fifths from base of rostrum. 

 Prothorax slightly wider than long, base much wider than 

 apex, sides rather suddenly constricted near apex, and thence 

 oblique to base; with small punctures fairly numerous in. 

 some places. Elytra strongly convex, subcordate, about once 

 and one-half as long as greatest width : narrowly striated, 

 with small punctures in striae, the interstices very finely 

 transversely or obliquely strigose or wrinkled. Length, 

 3i mm.

In my table would be placed with argutulum, from 

 which it differs in being considerably larger, the prothoracic 

 punctures finer, the elytral striae much finer, and the pro- 

 thorax and elytra of different shape. In appearance it 

 strongly resembles terrre-regince, but the elytra are ap- 

 parently glabrous. The prothorax not bulged out in middle 

 readily distinguishes it from t enui striatum . 



On close examination an extremely short and sparse 

 pubescence can be traced, but it is so very indistinct (from 

 most directions it is quite invisible under a Coddington lens) 

 that the species could quite reasonably be regarded as glab- 

 rous. There is a short, deep, curved, subapical impression 

 on each side of prothorax. The punctures towards sides of 

 elytra appear (from certain directions) to be transversely 

 impressed on the interstices, so that these look almost as if 

 stitched together. 



Apion niveodispersum, n. sp. 



Black, somewhat shining, antennae dull-red, front tibiae 

 feebly or not at all diluted with red. With snowy pubescence, 

 rather dense on sides of prothorax, sterna, about scutellum 

 and apex of elytra : sparser but more regular on abdomen, 

 legs, head, and base of rostrum, and absent elsewhere. 



Head with two shallow grooves between eves: with rather -
