668 RHYNCHOPHORA. 
Elytra moderately long, oval, a little wider than the prothorax; seriate-punctate, the interstices rugulose, 
3, 5, 7, and 9 raised, 3 sinuous and prominent. Beneath densely punctate. Mesosternum horseshoe- 
shaped. Legs rather short and stout ; femora sharply unidentate. 
Length 53-6, breadth 22-23 millim. 
Hab. Nicaraaua, Chontales (Belt). 
Three specimens. Smaller than C. quadriplagiatus; the prothorax black, with an 
ochreous spot at the base; the elytra maculated with black at the base and sides, and 
for the rest ochreous or fulvous, the third interstice sinuously raised ; the median 
carina of the rostrum extending upwards on to the front of the head; the second 
ventral segment scarcely longer than the third. 
64. Cryptorrhynchus bifenestratus, sp.n. (Tab. XX XIII. fig. 1, ¢.) 
Elongate-ovate, nigro-piceous, the antenne ferruginous ; thickly (the disc of the prothorax sparingly) clothed 
with rather coarse brown scales, the prothorax with a few ochreous scales at each hind angle and on the 
median lobe, the elytra variegated with black, and each with a large, subtriangular, sordid ochreous 
patch at about the middle of the disc (the black scales clustered around this, and also condensed into a 
small spot on the suture towards the apex), the scutellum ochreous, the legs fusco-annulate ; the elytra 
also set with scattered, semierect, setiform scales. Head rugulosely punctate, the eyes distant; rostrum 
short, curved, thickly punctate, rugose at the base, the antenne inserted behind the middle, joint 2 of 
the funiculus a little shorter than 1, the club ovate. Prothorax broader than long, rounded at the sides 
anteriorly, feebly constricted and much narrowed in front, deeply bisinuate at the base; densely, rather 
coarsely punctate. Scutellum rounded. Elytra rather long, convex, very little wider than the prothorax, 
narrowing from near the base, produced at the apex, the humeri obtuse; seriate-punctate, the alternate 
interstices finely seriato-granulate, 3 and 5 raised. Beneath closely punctate; first ventral segment 
depressed down the middle. Mesosternum broad, prominent, feebly emarginate. Femora feebly 
unidentate, the anterior pair linear. Tibie almost straight, subangulate at the base externally. Anterior 
tarsi slightly elongated, and with a few long projecting hairs. 
Length 53, breadth 22 millim. (¢.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen. Amongst the comparatively few species with hairy anterior tarsi in 
the male, C. bifenestratus may be known by its short rostrum, the broad, shallowly 
emarginate mesosternum, the narrow metathoracic episterna, the deeply bisinuate base 
of the prothorax, the almost straight tibie, &c. The pallid discoidal patch on each 
elytron is partly surrounded by a border of black scales.

Hab. Nortn America (Mus. Brit.), Carolina!4, Middle and Southern States 2.— 
Mexico * * (Mus. Brit.); Guatemaua, Las Mercedes (Champion). 
This species is described by Boheman as having a Y-shaped or cruciform white 
patch on the prothorax and a large, common, subtriangular, blackish patch at the base
