680 RHYNCHOPHORA. 
the sides. Scutellum rounded. Elytra a little wider than the prothorax, subparallel in their basal half, 
produced at the apex, the humeri obliquely truncated in front ; seriate-punctate, the interstices rugulose, 
3, 5, and 7 raised, convex, the ridge on 3 interrupted (appearing swollen below the base and at the 
middle). Beneath closely, finely punctate. Mesosternum horseshoe-shaped. Femora clavate, each with 
an acute tooth. 
Length 44, breadth 24, millim. ( 9.) 
Hab. Mexico, Texpam in Vera Cruz (Sad/é). 
One specimen. Less elongate than C. dorsalis, the prothorax feebly sinuate at 
the base, the median carina wanting, the dark dorsal patch enclosing a short pale 
median line; the elytra shorter, without definite darker markings, the third interstice 
interruptedly raised and fasciculate, the raised scales very coarse. 
Species very small, subovate, densely squamose and setose, with the rostrum curved, slightly 
widened at the base, the eyes rather small, lateral, the antennal club ovate, the prothorax 
bisinuate at the base, with feebly-developed ocular lobes, the scutellum prominent, the elytra 
wider than the prothorax, the mesosternum prominent, arcuately or angularly emarginate, 
the metathoracic episterna narrow, the ventral segment 2 longer than 3, the femora feebly 
dentate, the anterior pair sometimes unarmed. (Nos. 90, 91.) 
90. Cryptorrhynchus bisinuatus, sp.n. (Tab. XXXIII. fig. 23, ¢.) 
Subovate, piceous, the antenne and the tips of the tarsi ferruginous; densely clothed with pale brown scales, 
with whitish scales intermixed, the latter condensed into a median line on the head and prothorax 
and an ill-defined, broad, interrupted, transverse, subapical fascia on the elytra, the prothorax with two 
sharply-defined, sinuous, black vittee on the posterior lobe and the elytra slightly mottled with black at 
the sides, towards the apex, and across the middle of the disc; the upper surface also set with short, 
scattered, erect, black and whitish, setiform scales, which on the elytra are mainly confined to the alternate 
interstices, the legs setose. Head densely punctate, the eyes rather small and widely separated ; rostrum 
short, stout, flattened, feebly curved, squamose and rugulose at the base and for the rest bare, shining, 
and minutely punctate, the antenne inserted at a little behind the middle, joints 3-7 of the funiculus 
transverse, 2 much shorter than 1, the club ovate. Prothorax slightly broader than long, narrowed and 
constricted in front, bisinuate at the base; densely, finely punctate. Scutellum rounded. Elytra 
considerably wider than the prothorax, gradually narrowing from the base, the humeri obliquely 
truncated in front; punctate-striate, the alternate interstices raised, the others almost flat. Beneath 
densely punctate. Mesosternum prominent, shallowly arcuate-emarginate. Legs short; femora feebly 
unidentate. 
Length 33, breadth 13 millim. (9.) 
Hab. GuaTEMALA, Cerro Zunil (Champion). 
One specimen. This insect is rather like C. sedulus; but it is smaller and narrower, 
and has a shorter rostrum, smaller and more widely separated eyes, and a sharply 
bivittate prothorax (in this respect resembling C. signifer), the elytral sete mainly 
confined to the raised, alternate interstices. 
91. Cryptorrhynchus duplaris, sp. n. 
Subovate, piceous, the antenne ferruginous; densely clothed with pale brownish scales, mottled above 
with darker brown, the elytra with an irregular double series of spots across the middle (reduced to one
