322 RHYNCHOPHORA. 
stout, considerably longer than the head and prothorax, coarsely punctate and feebly tricarinate, a little 
smoother at the tip in the 2, the antenne inserted at about the middle, the antennal club ovate. 
Prothorax transverse, constricted in front, the sides more rounded in the @ than in the g; densely, 
confluently punctate, the narrow interspaces raised into sinuous longitudinal ruge, the posterior half of 
the disc shining in the ¢. Elytra triangular, narrowly punctate-striate, the interstices roughly asperato- 
punctate. Beneath coarsely, closely punctate, the propleura obliquely strigose. Anterior coxe narrowly 
separated. Legs rather stout, rugosely punctate; tibie strongly unguiculate in the g, more feebly so 
in the Q. 
¢. Prosternum armed with two long or moderately long porrect spines, and very deeply excavate down the 
middle; anterior tibie slightly curved outwards (as in the Q); intermediate (fig. 26) and posterior 
tibie dilated on the inner side, and each armed with a short tooth at about one-third from the apex 
beneath ; first ventral segment broadly excavate down the middle. 
©. Prosternum shallowly sulcate. 
Length 24-34, breadth 13-2 millim. (¢ 2.) 
Hab. Mexico, Panistlahuaca in Oaxaca (Sallé) ; GuaTemata, Zapote, San Gerdnimo, 
Purula (Champion). 
Three males and five females. Recognizable by the rugose surface, the common 
interrupted, T-shaped, ochreous mark at the apex of the elytra, and the pronounced 
sexual characters. The small tooth on the intermediate and posterior tibie of the 
male is not visible from above. 
3. Centrinites laticrus, sp.n. (Tab. XVII. figg. 3, 3a, 4, ¢-) 
Rhomboidal, narrow, nigro-piceous, the tibia and tarsi fusco-ferruginous ; sparsely clothed with narrow, hair- 
like, intermixed whitish and fuscous scales, which are arranged in a single series down each elytral 
interstice (the second having a double row at the base), the prothorax with scattered, similar, ochraceous 
scales; the vestiture of the legs and under surface closer. Head finely punctate; rostrum strongly 
arcuate, stout, as long as the head and prothorax, striato-punctate, the antenne inserted at the middle, 
the antennal club ovate. Prothorax transverse, conical, constricted in front ; densely, confluently 
punctate, and with an indistinct raised median line. Elytra subtriangular, sharply punctate-striate, the 
interstices flat and roughly uniseriate-punctate. Beneath closely punctate ; first ventral segment 
broadly excavate. Prosternum shallowly sulcate and armed with two small conical tubercles. Anterior 
cox narrowly separated. Anterior tibie strongly unguiculate, hollowed on their inner edge from about 
the basal third to near the apex ; intermediate tibiw broadly (fig. 30), and the posterior pair moderately, 
dilated on the inner side from near the base, both sharply unguiculate at the tip and armed with a 
minute tooth on the lower side beyond the middle. 
Length 22, breadth 1} millim. (<¢.) 
Hab. Guaremata, Purula in Vera Paz (Champion). 
One male. Very like C. dentimanus (¢ ), but with the rostrum shorter and not so 
stout, the anterior tibia without triangular tooth on the inner edge, the other tibiee 
(the intermediate pair especially) broadly widened within and toothed beyond the middle 
beneath, the prosternum armed with two conical tubercles. Smaller than C. T-/flavum, 
the elytra without definite markings at the apex, the prosternal spines reduced to 
conical tubercles, the anterior tibie hollowed within, the intermediate tibie more 
dilated. :
