CRYPTORRHYNCHUS. 635 
ovate. Prothorax transverse, much narrowed in front, the sides rounded anteriorly and parallel behind, 
the base deeply bisinuate; coarsely, confluently punctate and feebly carinate. Scutellum oblong. Elytra 
much wider than the prothorax, elongate-subtriangular; with rows of coarse oblong punctures, the 
interstices 3, 5, and 7 narrowly costate, 3 and 5 sinuous. Ventral segments coarsely, sparsely punctate. 
Legs rather short and stout, the femora clavate and unidentate. 
Length 84, breadth 34 millim. (9.) 
Hab. Nicaragua, Chontales (Belt). 
One specimen. This insect is rather like Celosternus rugicollis, Boh., from Brazil, 
but has a shorter, less rugose prothorax, a shorter antennal club, a more slender 
rostrum, &c. ‘The sides of the prothorax are more rounded than in C. mistus and 
C. cordubensis. 
Species moderately large, oblong-ovate in form, thickly squamose, with the eyes distant, the 
rostrum short and curved, the prothorax much rounded at the sides, the elytral inter- 
stices rugulose and narrowly costate, the mesosternum arcuate-emarginate, the ventral 
segments 2—4 equal in length, the femora unarmed. (No. 4.) 
4, Cryptorrhynchus sublineatus, sp.n. (Tab. XXXI. figg. 11, lla, ¢.) 
Oblong-ovate, convex, nigro-piceous, the antennz and the tips of the tarsi ferruginous ; thickly clothed with 
intermixed whitish and brown scales, the whitish ones condensed into lines on the elytra, those on the 
prothorax larger and entirely brownish. Head densely, rugosely punctate, the eyes distant; rostrum 
short, stout, and curved, feebly dilated, rugose, and subcarinate at the base, the apical half bare and finely 
punctate, the antenne inserted at the middle, joint 2 of the funiculus slightly shorter than 1, the club 
ovate. Prothorax transverse, rounded at the sides, narrowed and feebly constricted in front; densely 
punctate. Scutellum rugulose and subcarinate. LElytra a little wider than the prothorax, gradually 
narrowing from near the base, broadly produced at the apex, the humeri obliquely truncated in front ; 
punctate-striate, the interstices densely rugulose, 2-9 narrowly costate. Beneath coarsely, densely 
punctate. Legs rather short, the femora and tibiz moderately stout, the femora unarmed, the tarsi 
comparatively slender. 
Length 64, breadth 2,% millim. ( 9.) 
Hab. Mexico, Vera Cruz (ge). 
One specimen. Smaller and less elongate than C. latisquamis, the rostrum much 
shorter, the elytral interstices 2-9 narrowly costate, the femora without trace of tooth. 
The less transverse eyes, unarmed femora, &c., separate it from Africhis costirostris. 
This species will probably have to form the type of a new genus. 
Species moderately large, oblong-ovate in form, thickly squamose, with the eyes well separated, 
the rostrum curved, the prothorax subtruncate at the base, the elytra somewhat conical, with 
flattened interstices, the mesosternum much raised and feebly emarginate, the ventral 
segment 2 nearly as long as 3 and 4 united, the femora obsoletely dentate. (No. 5.) 
5. Cryptorrhynchus belti, sp.n. (Tab. XXXI. figg. 12, 12 a.) 
Oblong-ovate, convex, shining, nigro-piceous, the antenne and the tips of the tarsi ferruginous ; the prothorax 
thickly clothed with coarse, intermixed, reddish-brown, ochreous, and whitish scales, the elytra with
