CRYPTORRHYNCHUS. 673 
down the middle of the disc, and the elytra with a large transverse patch at the base and a few small 
spots on the apical half, black or blackish, the femora and tibis nigro-annulate; the upper surface also 
set with coarse, erect, setiform scales, the legs setulose. Head densely punctate, the eyes rather large 
and well-separated ; rostrum short, curved, stout, rugosely punctate, the antennee inserted at the middle; 
joint 2 of the funiculus nearly as long as 1, the club ovate. Prothorax transverse, rounded at the 
sides, constricted and much narrowed in front; densely punctate and feebly carinate. Elytra a little 
wider than the prothorax, parallel at the base, the humeri obtuse ; seriate-punctate, the interstices 3 
and 5 strongly, and 7 more feebly, raised. Beneath densely punctate. Mesosternum feebly arcuate- 
emarginate. Legs short; femora strongly unidentate; posterior tibie of the g¢ deeply hollowed 
towards the apex within and with the terminal claw elongated. 
Length 47-44, breadth 2-23 millim. (¢.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Two males. A third specimen (@?) from Chiriqui seems to belong to the same 
species ; it is much smaller and has the black basal patch of the elytra extending 
broadly down the suture to beyond the middle and there truncated. The peculiar 
form of the posterior tibie of the male separates C. stnuatipes from C. dorsalis and 
others. 
75. Oryptorrhynchus medioximus, sp.n. (Tab. XXXIII. fig. 12, ¢.) 
Oblong-ovate, black, the antennz and the tips of the tarsi ferrugincus; thickly clothed with dark brown 
scales, with blackish scales intermixed, the elytra each with an irregular transverse ochreous fasvia at 
about the middle, the femora and tibiz more or less distinctly annulate with cinereous or ochreous; the 
upper surface also set with short, semierect, setiform, blackish and ochreous scales, the legs setulose. 
Head densely punctate, the eyes distant; rostrum stout, curved, about as long as the prothorax, rather 
sparsely punctate, the antennee inserted at a little behind the middle, joint 2 of the funiculus nearly as 
long as 1, the club ovate. Prothorax broader than long, constricted and much narrowed in front, 
densely punctate. Elytra a little wider than the prothorax, subparallel in their basal third, the humeri 
obtuse ; seriate-punctate, the interstices 3 and 5 raised. Beneath densely punctate. Mesosternum 
prominent, feebly arcuate-emarginate. Legs rugose, short ; femora obsoletely dentate. 
Length 43-43, breadth 2 millim. (2.) 
Hab. Guatemaa, Cerro Zunil (Champion). 
Three specimens. The dark vestiture and the irregular transverse ochreous median 
fascia on each elytron distinguish C. medioximus from its nearest allies. The erect 
scales on the prothorax are almost entirely black, but they are not clustered into 
fascicles. 
76. Cryptorrhynchus tirunculus. (Tab. XXXIII. figg. 13, 134, 3.) 
3. Cryptorhynchus tirunculus, Boh, in Schonh. Gen. Cure. iv. p. 68*. 
Oblong-ovate, dull, black, the antennz fusco-ferruginous ; the head and prothorax sparsely, the rest of the 
surface densely, clothed with sordid ochreous or whitish scales, the scales on the prothorax usually 
condensed into three evanescent, interrupted lines on the disc, the elytra with a very large triangular 
patch at the sides (extending from a little below the shoulder to far beyond the middle, and nearly 
reaching the suture), and a common transverse patch at the base, brownish-black, the tibize near the 
base and the femora at the middle and apex annulate with fuscous, the elytral interstices each with a 
row of short, coarse, suberect sete, the tibie setulose; the vestiture of the abdomen in great part fuscous. 
Head rugosely punctate, the eyes widely separated; rostrum short and stout, feebly curved, in the ¢
