OTIDOCEPHALUS. 241 
“moderately elongate, gradually widening to about the middle, the humeri a little swollen ; finely seriate- 
punctate, the interstices flat, closely, very minutely punctate, with intermixed setigerous impressions. 
Legs comparatively short and stout; femora each with a rather short triangular tooth ; anterior tibie 
strongly sinuate within. 
Length 6, breadth 23 millim. 
Hab. Mexico, Atlixco, Puebla (fHége). 
One specimen. Recognizable by the cupreous coloration, the close pubescence, 
the whitish suture, the intermixed short blackish and white setee on the elytra, and 
the reddish tarsi. 
18. Otidocephalus pellitus. 
Otidocephalus pellitus, Chevy. Ann. Soc. Ent. Fr. 1877, p. 175°. 
Elongate, shining, eneous, the antennz (the club excepted) usually ferruginous ; somewhat thickly clothed 
with intermixed, decumbent, fulvous and whitish pubescence, which is quite coarse on the elytra, the 
interstices of the latter each with a row of rather closely placed, long, erect or suberect, blackish sete, 
the vestiture of the legs and under surface entirely whitish. Head closely punctate, the eyes widely 
separated ; rostrum nearly as long as the prothorax, rugosely punctate-sulcate, with a smooth raised 
median line; antenne with joint 2 of the funiculus shorter than 1, and 3-7 each shorter than 2, the 
club ovate. Prothorax long, subcylindrical, coarsely punctate, the punctures here and there transversely 
confluent on the dise. Elytra elongate, much wider than the prothorax, widening to a little beyond the 
middle ; finely seriate-punctate, the interstices flat, closely, very minutely punctate, and with coarser 
setigerous impressions. Fifth ventral segment feebly emarginate at the apex in the ¢. Femora each 
with a short triangular tooth. Anterior tibiew feebly sinuate within, 
Var.? The dark setosity more abundant and extending to the prothorax, the elytra smoother, with the 
fulvous and white pubescence much finer. 
Length 61-7, breadth 23-3 millim. (¢d -) 
Hab. Mexico (Mus. Holm.), Chinautla (Lohr, in Mus. Berol.), Toxpam, Cordova’, 
and Yolotepec (Sallé), Oaxaca (Hdége). | 
Chevrolat’s diagnosis of this species was made from a partially abraded example *, 
which I have seen, and he does not mention the sete, which are conspicuous and 
numerous on the elytra. There are three specimens of O. pellitus in the Sallé 
collection and one in the Berlin Museum. ‘The varietal form, from Oaxaca, may prove to 
belong to a different species. ‘The fulvous hairs predominate on the elytra in all of them. 
19. Otidocephalus lineipennis. (Tab. XIII. figg. 13, 13a.) 
Otidocephalus lineipennis, Chevr. Ann. Soc. Ent. Fr. 1877, p. 176°. 
Hab. Mexico, San Andres Tuxtla (Sallé'), Zongolica (Flohr, in Mus. Berol.) ; 
GUATEMALA, Panzos in Vera Paz (Conradt) ; NicaraGua, Chontales (Belt, Janson). 
Distinguishable amongst its allies by the five compact lines of white decumbent 
pubescence on each elytron (one on each of the interstices 1, 3, 5, 7, and 9, and each 
formed by two or three rows of hairs, the others being almost bare and impunctate to 
* The glabrous spaces on the prothorax and elytra mentioned by him are simply due to abrasion.
