650 RHYNCHOPHORA. 
setose at the base, 3 widened, much raised, and strongly setose at the middle. Beneath opaque, finely 
punctate. Mesosternum somewhat declivous, v-shaped. Legs short ; femora acutely unidentate ; tarsal 
claws very small. 
Length 3, breadth 14 millim. (<¢.) 
Hab. Panama, Bugaba (Champion). 
One specimen. This small species has somewhat the facies of a Conotrachelus, the 
elytra having a nigro-setose crest at about the middle of the third interstice, and 
the prothorax two short ridges on the disc, as in various members of that genus. The 
vestiture is sparse and does not hide the sculpture. ‘The eyes are completely hidden 
in repose. 
Species moderately large, oblong-ovate, finely squamose, with the rostrum stout, short, and 
curved, the antennal club elongate, the prothorax strongly transverse, the elytra with 
smooth scattered tubercles and ten irregular rows of punctures, the mesosternum broad, 
arcuate-emarginate, the ventral segments 2-4 equal in length, the anterior femora bi-, the 
others unidentate. (No. 30.) 
30. Cryptorrhynchus lacteicollis, sp. n. (Tab. XXXII. figg. 4, 4 a.) 
Oblong-ovate, rather broad, opaque, the elytral tubercles and the under surface shining ; black, the antenner, 
tarsi, and tubercles more or less ferruginous; the prothorax with a dense clothing of agglutinated, small, 
- white scales, the elytra with brown scales and each with an oval velvety dark brown spot on the fourth 
interstice near the base, the head, under surface, and legs with intermixed brown and white scales, the 
latter clustered into small patches on the femora and tibie. Head densely, finely punctate, canaliculate 
on the vertex, the eyes large, prominent, and widely separated ; rostrum exceedingly stout, curved, nearly 
as long as the head and prothorax, densely, rugulosely punctate at the base, the apical half more sparsely 
punctate and shining, the antenne inserted at the middle, joint 2 of the funiculus a little longer than 1, 
3-7 moniliform, the club stout, oblong-ovate, acuminate, longer than the preceding five joints united. 
Prothorax strongly transverse, abruptly narrowed in front and also a little narrowed behind, bisinuate 
at the base and emarginate at the apex, the ocular lobes moderately large; densely, finely punctate, 
feebly carinate. Scutellum oval. Elytra much wider than the prothorax, gradually narrowing from the 
base ; uneven, densely rugulose, and interruptedly seriate-punctate, the alternate insterstices from the 
base to the apex studded with a few widely scattered smooth tubercles, the one on 3 at the commencement 
of the apical declivity oblong and much larger than the rest. Beneath closely, finely punctate. . 
Mesosternum very broad, semicircularly emarginate, the cavity reaching to the middle of the intermediate 
coxe. Legs short, stout; femora strongly clavate, the anterior pair with two approximate teeth, 
the others unidentate. 
Length 73, breadth 33 millim. (¢.) 
Hab. Mexico, Toxpam in Vera Cruz (Sallé). 
One specimen only of this remarkable form has been received. The milky-white 
scales on the prothorax completely hide the sculpture, and the rugulosity of the 
elytra is so dense as to make the upper surface appear opaque. The anterior femora 
have a conspicuous additional tooth on the outer edge of the larger one. The ocular 
Tobes of the prothorax do not cover the eyes.
