ODONTOCORYNUS.—PSEUDOGERAUS. 319 
3. Odontocorynus sutura-flava, sp.n. (Tab. XVI. figg. 33, 33, 3.) 
Centrinus sutura-flava, Chevr. in litt. 
Oblong, black; the prothorax, scutellum, and first elytral interstice with a continuous, dense line of rather 
large, ochreous or whitish scales, the entire under surface also densely clothed with broad white or. pale 
ochreous scales; the vestiture of the rest of the upper surface brown, very fine, and hair-like, that of the 
rostrum and legs yellowish-white or white. Head closely punctate, shallowly foveate between the eyes; 
_ rostrum a little longer than the head and prothorax, arcuate—in the ¢ opaque, stout, and striate-punctate, 
‘in the 2 shining, more slender throughout, and very sparsely, finely punctate from near the base,—the 
antenne inserted at a little behind (9) or far beyond(¢) the middle, the club ovate. Prothorax 
broader than long, rounded at the sides anteriorly, constricted and narrow in front; densely, rather 
coarsely punctate, the punctures separate one from another. Scntellum transverse, large. Llytra 
oblong-subtriangular, narrowly punctate-striate, the interstices densely, roughly punctate. Beneath 
densely punctate. Prosternum slightly hollowed down the middle. 
é. Antenne with joint 7 of the funiculus dentiform within and the club armed with a short sharp tooth near 
the base beneath (fig. 33a); first ventral segment flattened down the middle. 
Length 32-44, breadth 13-24 millim. (d Q.) 
Hab. Mexico (Dupont and Truqui, in Mus. Brit.), Atlixco (U.S. Nat. Mus.), Puebla 
(Sallé), Mexico city (Hége), Tehuantepec (Mus. Brit.). 
Five males and seven females. Easily known by the dense, imbricate line of ochreous 
scales along the suture of the elytra, this being continued forwards on to the scutellum 
and the disc of the prothorax, and the dense, coarse, whitish vestiture of the under 
surface. The tooth on the antennal club is acute. 
4, Odontocorynus larvatus. (Tab. XVI. figg. 34, 34a, 2.) 
2. Centrinus larvatus, Boh. in Schénh. Gen. Cure. viii. 1, p. 218°. 
Centrinus (Odontocorynus) larvatus, Casey, Ann. N. York Acad. Sci. vi. p. 577, nota *. 
Hab. Mexico !? (coll. Chevrolat). 
The type, a female, of this species has been communicated by Dr. Sjéstedt. Itisa 
moderately large, robust form, densely albo-squamose beneath, and thickly clothed 
above with rather broad whitish scales, those on the elytra (fig. 34 a) arranged in a 
closely-packed double or treble series down each interstice and clustered into a dense 
patch on the scutellum ; the prothorax is densely punctate, except along the smooth 
median line; the elytra are narrowly striate; the prosternum is slightly depressed 
down the middle anteriorly ; the mandibles are pointed ; the antennal club is rather 
small. 
C. larvatus, Boh., is nearly related to the North-American Centrinus scutellum-album 
(Say) and C. salebrosus, Casey, both of which are included by Casey in Odontocorynus. 
The antennal club is, no doubt, similarly toothed at the base in the male of the 
Mexican insect. an 
PSEUDOGERALUS, gen. nov. 
Rostrum arcuate, stout, moderately long; mandibles curved, notched within, decussate at the tip; antennal 
club ovate; prothorax constricted and subtubulate in front, feebly sinuate at the base; scutellum free,
