THECESTERNINE. 
THECESTERNUS (p. 86). 
Thecesternus humeralis (p. 86). 
Mr. Pierce, in his recent revision of this genus [Proc. U.S. Nat. Mus. xxxvii. 
pp. 334-339 (1909)], recognizes several of Leconte’s species (previously sunk as 
synonyms of 7 humeralis) as distinct, and describes four others as new. The two 
specimens from Tamaulipas referred by Dr. Sharp to 7. humeralis, and another since 
received from Sabinas in Nuevo Leon (Flohr), seem to belong to T. affinis, Lec. 
We are indebted to Mr. Wickham for a series of 7. humeralis, Say, from Cafion City, 
Colorado, and to the U.S. Nat. Museum for co-types of 7. maculosus, albidus, and foveo- 
latus, Pierce. T. affinis differs from 7. humeralis in having less prominent humeri and 
the elytra more rounded at the sides, in this respect approaching 7’. maculosus. 
OTIORHYNCHIN. 
OTIORHYNCHINA APTER. 
OPHRYASTINA, 
OPHRYASTES * (p. 88). 
Ophryastes bituberosus (p. 90). 
The species recorded by Mr. Pierce [Proc. U.S. Nat. Mus. xxxvil. p. 344 (1909) ] 
from Texas and New Mexico (a specimen of which, from San Diego, is now before me) 
under the above name is O. ovipennis, Sharp. 0. tuberosus, Lec., from New Mexico, 
may be known from 0. bitubercsus by the feebly, transversely depressed base of the 
rostrum, and the rather more convex, oval elytra, without trace of humeri. 
4 (a). Ophryastes tetralobus, sp.n. (Tab. XV. figg. 1, 1a.) 
Moderately elongate, black, clothed with intermixed whitish and fuscous scales, and also set with minute, 
scattered, short, decumbent hairs. Rostrum very broad, faintly transversely depressed at the base, 
deeply trisulcate, the sulci separated by two posteriorly converging ridges, the median groove extending 
backward along the flattened, laterally sulcate, inter-ocular portion of the head, the lateral grooves also 
long. Prothorax strongly transverse, laterally bilobato-dilatate, constricted just before the base, the 
groove in front of the basal ridge deeply impressed laterally, obsolete in the centre, the depressed narrow 
basal portion feebly produced in the middle behind; the surface obliquely wrinkled and sparsely, coarsely 
punctate, Elytra moderately convex, oblong-oval, not wider than the dilated portion of the prothorax, 
with a short, abrupt, neck-like constriction at the base; coarsely punctate-striate, the interstices 
convex. 
Length 134, breadth 54 millim. (<7?) 
Hab. Mexico, Sabinas in Nuevo Leon (ex Flohr). 
* O. wickhami, Sharp, from Winslow, Arizona, described in a footnote on p. 88, belongs to Hupagoderes 
(and is indeed so labelled in the Sharp collection), the male having the third tarsal joint dilated and the lobes 
clothed with adhesive pubescence beneath [¢f. Fall, Trans. Am. Ent. Soc. xxxvi. p. 189 (1910)]. A specimen 
of it from Arizona has been sent me by the U.S. Nat. Museum (det. Pierce) as HZ. argentatus, Lec.
