of the acute humeral angle seen in that species. The rostrum has only very obsolete 
impressions at the sides. The scape of the antenne is dark, the first six joints of 
the funiculus are pale, the seventh being black like the club, and so closely applied 
thereto as to appear a part of it. Thorax uneven, indistinctly sculptured, very 
strongly transverse, closely applied to the base of the elytra at the angles, less so in 
the middle, so that the scutellum is not quite concealed. Elytra with very obsolete 
sculpture consisting of vague large pits, arranged serially. One specimen. 
CACCOPHRYASTES, gen. nov. 
Palpi maxillares exserti. 
This genus is proposed for a species, of which we have received only a single 
example, having the peculiarity of structure mentioned above, but in other respects very 
closely allied to Ophryastes and Eupagoderes, and in fact much resembling 0. vittatus, 
Say. I have hesitated as to whether the exposure of the maxillary palpi might not be 
the result of some abnormality of structure, but I can find no reason for believing this 
to be the case; and the mentum, moreover, is peculiarly formed, its front margin being 
directed only slightly obliquely upwards, instead of abruptly as in all the other forms 
of Ophryastini I have examined. There is a slight thickening of the sides of the 
prothorax, but no distinet projection ; the third tarsal joint is bilobed, and each lobe 
possesses a patch of adhesive pubescence beneath; the apex of the hind tibia is feebly 
cavernous. The scutellum is rather largely exposed. The other characters are those 
of Ophryastes and Eupagoderes. 
There are other genera of Otiorhynchide with the mentum in front not covering 
the palpi, but none of them are allied to Caccophryastes. Itis very possible that when 
other examples of the species for which I have established the genus are found, it may 
be discovered that the palpi are normally concealed by the mandibles when the mouth 
is closed; but in that case the insertion of the palpi in sucha way as to project towards 
the front of the mouth, instead of upwards towards its interior, will probably be found 
to differentiate the genus satisfactorily.

Rostrum without basal constriction, with a deep elongate median channel extending 
on to the forehead, and with a short, rather deep lateral impression. Thorax short, 
with coarse unevenly distributed sculpture; ocular lobes feeble; the sides greatly 
rounded and a little tumid, especially behind. Scutellum largely exposed behind the
