42 TEliTIAEY EHYNCUOPnOEOUS COLEOPTERA. 



allowing- more tluui the ratlier small obovate transverse eyes to be seen. 

 The Ijeak is more than two-thirds as long as the prothorax, broad and equal, 

 broadly rounded at the tip, with scarcely any sign of an apical expansion. 

 Thorax twice as broad as long, somewhat tapering, the surface roughened 

 and pei-haps punctate. Elytra a little broader than the thorax, each fully 

 twice as long as broad, br(iadly rounded apically, suberiual, the surface 

 very faintly scored with tine stria? and profusely, finel)', and faintly punctate. 



Length, including rostrum, 4"'"; elytra, 2-5'"'"; breadth, 2 ■""'.

The single specimen is liere shown upon a side view. Its form is 

 entirely similar to that of the last species, but the head is not so extremely 

 short. Tlie eye is large and circular; unfortunately the beak, partially 

 seen at first, was Ijroken and lost in attempting to work it out from the 

 matrix; what was seen did not show it to differ from that of the preceding. 

 The thorax is fully half as high again as long, tapering, hardly arched 

 above, the surface rather coarsely and obscurely punctate. Elytra similarly 

 punctate without reference apparently to the similarly coarse and somewhat 

 obscure striae; they are together evidently bi'oader than the thorax, and 

 each is considerably less than twice as long as broad, rapidly descending, 

 l)ut well rounded posteriorly, moderately arched above. Femora scarcely 

 enlarged, very faintly and finely striate.
