Before abrasion there is a very strong crest on the prothorax, 

 rapidly rising in front till it is as high above the apex of the protho- 

 rax as tlie head is long; seen tVom in front (of perfect specimens 

 only) the crest appears to be in the form of a triangle at the apex, 

 with a much smaller crest beneath it. On the elytra there are two 

 other strong crests, each commencing on the third interstice at the 

 basal tiiird, and near summit of posterior declivity suddenly 

 dellected so that the two become conjoined, or almost conjoined, at 

 suture. The crests, however, are larger and much more distinct on 

 some specimens than on others, and may actually be due in part to 

 regular accretions of mud or exudation, in addition to the clothing. 

 That on the prothorax is seen, on abrasion, to be supported by a 

 slight convexity of the derm, not on a strong carina. On the elytra, 

 however, the crests are supported by a transverse carina and the 

 raised interstices. 



On some ot the specimens the rostrum is slightly wider behind 

 than in front of anteanis, on others it feebly but regularly increases 

 in width from base to apex; the difference probably being sexual. 



664. FE'RGUSONIA BITUBERGULATA n. sp. 



Black, rostrum legs and antennae reddish .Very densely clothed with 

 muddy brown scales; interspersed with a few stout whitish setse. 



Rostrum distinctly longer than prothorax, very slightly but 

 regularly increasing in width from base to apex; punctures con- 

 cealed beliind antennal insertion, small and numerous in front of 

 same. Prothorax moderately transverse, with a strong subapical 

 constriction, punctures small und normally concealed. Elytra not 

 much longer than wide, parallel sided to beyond the middle; with 

 rows of very large, deep, partially concealed punctures; third 

 interstice slightly raised, witti a small tubercle near summit of 

 posterior declivity. Length 1 3/4 mill.

Before abrasion the tubercle on the third interstice appears to be 

 fairly large, but on abrasion it is seen to be rather small. The 

 general surface after abrasion is not much different to that of the 

 preceding species, but before abrasion it has a very different look, 

 owing to the absence of the conspicuous prothoracic crest of that 

 species.
