Considerably larger than N. major, with smaller punctures, 

 rostrum longer and more dilated in front. The front of the pro- 

 thorax, at first glance, appears to be part of the head, owing to 

 the unusually deep subapical constriction. 



Aphanocorynes semirufirostris, n.sp. 



Black, somewhat shining, apical half of rostrum, antennae, and 

 legs reddish. 



I/ead impunctate at base, with small and not very dense, but 

 distinct, punctures elsewhere ; interocular fovea very feeble. 

 Rostrum rather wide and somewhat flattened, somewhat nar- 

 rowed from antennae to base, almost parallel-sided in front of 

 same; punctures much as on head between eyes, but becoming 

 smaller and denser in front. Prothorax flat, sides rather strongly 

 inflated from near apex to near base; punctures slightly stronger 

 than those between eyes, becoming denser on sides; with a vague 

 medio-basal impression, from which a vague impunctate line is 

 traceable to the subapical constriction Elytra scarcely wider 

 than widest part of prothorax, parallel-sided to apical fourth ; 

 with rows of not very large punctures, in narrow striae; interstices 

 much wider than striae, with small punctures and fine transverse 

 impressions. Length, 3J-4 mm.

In general appearance, close to Notiosomus 7'ugosipennis, and 

 with very similar elytral sculpture, but rostrum shorter and 

 wider, abdomen of male more deeply impressed along middle of 

 two basal segments, and apical segment very different. From A. 

 depressus, it differs in being smaller, rostrum shorter, with the 

 apical half nearly always paler than the basal half, prothorax 

 less inflated near the base, etc. The elytra appear to be some- 

 w^hat wrinkled, each of the fine transverse impressions connecting 

 two punctures in adjacent striae ; and there is, usually, one 

 between each of the minute punctures on the interstices, so that 

 these seem to be divided into small squares, each with a central 

 puncture; but, towards the apex, the transverse impressions and 

 fine punctures are more crowded and irregular. The rostrum of 

 the male is somewhat wider than that of the female, and the two
