CRYPTORRHYNCHUS. 643 
apex, almost straight, flattened basally, rugosely punctate to the tip in the g, more sparsely and less 
coarsely punctate in the 9, the antenne inserted at a little behind the middle, joints 3-7 of the funiculus 
transverse, the club ovate. Prothorax broader than long, narrowed and feebly constricted in front; 
coarsely, rather closely punctate. Elytra a little wider than the prothorax, subparallel in their basal 
half, the humeri obtuse; coarsely seriate-punctate, the interstices 3, 5, and 7 more or less raised, 
3 slightly swollen below the base. Beneath dull, rather finely punctate. Mesosternum very prominent, 
broad, shallowly arcuate-emarginate. Legs short; femora feebly unidentate. 
Length 24-34, breadth 14-13 millim. (¢ 9.) 
Hab. Mexico, Motzorongo (Flohr), Teapa (Hége, H. H. Smith), Jalapa, San Juan 
Bautista, Oaxaca (Hodge); British Honpuras, Belize, Rio Hondo (Blancaneauz) ; 
GuATEMALA, Cahabon and Tamahu (Champion); Panama, Bugaba (Champion). 
Numerous examples. The description is taken from those in the best condition, 
with the sides of the prothorax and elytra lineate with whitish, the others having the 
vestiture brown and the blackish markings indistinct. One from Bugaba has the sutural 
region of the elytra and a space down the middle of the prothorax infuscate. The 
sculpture is in great part hidden by the dense vestiture. C. curtirostris is nearly related 
to C. placatus, but it is smaller, the alternate elytral interstices are raised, and the third 
is a little more swollen below the base, and has two or three scattered black spots. 
Species small, oblong-ovate, squamose, with the rostrum short, stout, and very feebly curved, 
the eyes distant, the antennal club ovate, blunt at the tip, the prothorax bisinuate at the 
base, with prominent ocular lobes, the scutellum minute, prominent, the elytra a little 
wider than the prothorax, with the alternate interstices costate, the mesosternum prominent, 
arcuate-emarginate, the metathoracic episterna moderately broad, the ventral segment 2 
longer than 3, the first suture arched, the femora unidentate, the tooth on the anterior pair 
long. (No. 18.) 
18. Cryptorrhynchus yucatanus, sp. n. 
Oblong-ovate, nigro-piceous, the antenne obscure ferruginous; thickly clothed with intermixed whitish and 
pale brown scales, the whitish ones condensed into a median vitta on the prothorax and a common 
cruciform patch on the elytra. Head rugosely punctate, flattened between the widely separated eyes ; 
rostrum short, very stout, feebly curved, somewhat flattened towards the apex, rugose at the base and 
thickly punctate thence to the tip, smoother in the Q, the antenns inserted behind the middle, joint 2 
of the funiculus much shorter than 1, the scape short, the club ovate, blunt at the tip. Prothorax 
broader than long, constricted and much narrowed in front, bisinuate at the base; densely punctate. 
Scutellum minute, smooth. Elytra a little broader than the prothorax, narrowing from near the base ; 
seriate-punctate, the interstices rugulose and obsoletely granulate, 3 and 5 rather strongly, and 7-9 
more feebly, costate. Beneath coarsely, closely punctate. Legs rather short; anterior femora sharply, 
the others moderately, unidentate ; anterior tibie sinuate within. 
Length 43-5}, breadth 2-23 millim. (d 2.) 
Hab. Mexico, Temax in N. Yucatan (Gaumer). 
Two rather worn specimens. The common, cruciform, whitish patch on the elytra, 
the minute scutellum, the broad, semicircularly emarginate mesosternum (which is 
formed as in Gasterocercus), the blunt antennal club, &c., sufficiently distinguish 
C. yucatanus. It is not unlike Graphonotus albescens, but has a much shorter rostrum,
