106 RHYNCHOPHORA. 
vitta of condensed whitish pubescence; the prothorax with a large, deep, rounded 
impression before the base. ‘The rostrum of the female is slender, feebly curved, and 
a little longer than the prothorax, that of the male being stouter and slightly shorter. 
In the two specimens ( ¢ ) from the Sturm collection the second joint of the funiculus 
is longer than the first, and this is the case in nearly all our other examples, including 
the six from Guatemala; the second joint, however, seems to vary in length in this 
species, irrespective of sex. The first ventral segment is unimpressed in both sexes. 
The Guatemalan specimens have the submarginal vitta of the elytra almost obliterated, 
except at the apex. Length 10-16, breadth 25-45 millim.

This species is apparently not rare in the elevated districts of Central and Western 
Mexico, whence we have received twenty-one specimens. It has the prothorax broadly 
flattened or depressed on the disc, and the elytra flattened on the disc towards the 
base. The pubescence of the upper surface is cinereous, and slightly mottled in 
places, being sufficiently condensed at the sides of the prothorax to form vitte. The 
rostrum is moderately stout, barely as long as the prothorax in the ¢g, and slightly 
longer in the @. The first ventral segment is faintly depressed down the middle in 
the ¢. Length 8-13, breadth 24-4 millim. |

Hab. Mexico } (Sallé, ex coll. Sturm), Orizaba (Sallé), Teapa (H. H. Smith). 
Of this species we have two female specimens from the Sallé collection, labelled 
L. conicicollis, Sturm, and a pair from Teapa; there is also a female of it in Dr. Sharp’s 
collection, correctly identified. The pubescence of the upper surface is cinereous and 
more or less mottled, it being longer at the sides of the prothorax and beneath. The 
rostrum of the male is moderately stout and barely as long as the prothorax, that of 
the female being a little longer and more slender. ‘The prothorax is subconical, very 
densely; minutely punctate, with scattered, intermixed, coarser punctures; the basal 
impression is large and deep. ‘The elytra are rather convex, broader than the 
prothorax, but of the same width at the base, moderately long, somewhat rapidly 
narrowing from about the middle, with the apices slightly produced; the depression 
behind the scutellum is deep. The first ventral segment is depressed along the centre 
in the male.
