129. Conotrachelus parvicollis, sp. n. 
Conotrachelus parvicollis, Deyr. in litt. 
Conotrachelus rufitarsis, Chevr. in litt. 
Ovate, the head and prothorax dull, the elytra shining, black or piceous, the elytra variegated with rufo- 
piceous or ferruginous (usually leaving an angulated median fascia, the suture thence to the scutellum, 
and some markings towards the base and apex, black), the legs in part and the antenne ferruginous; the 
vestiture rather close (sparser on the prothorax), condensed into patches on the elytra and becoming 
denser on the apical declivity, fulvous or brownish, intermixed with white, the prothorax with an 
interrupted, curved, faint white line on each side of the disc, and the elytra with a short streak at the 
base of the third interstice and often a subapical transverse fascia white or ochreous, the femora annulate; 
the upper surface also set with numerous stiff, semierect, whitish and dark brown sete, the legs setulose. 
Head convex, densely punctate, transversely depressed above the eyes; rostrum very stout, arcuate, about 
as long as the head and prothorax, densely, rugulosely punctate and finely carinate, the antenns: inserted 
near the tip, joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, rounded at the 
sides anteriorly, narrowed and constricted in front, feebly bisinuate at the base; closely, rugulosely 
punctate. Elytra rather short, nearly twice as wide as the prothorax, abruptly declivous beyond the 
middle, slightly constricted behind the obliquely truncated humeri, and narrowing from about the basal 
third ; coarsely seriate-punctate, the punctures subquadrate, the interstices rugulose, narrow, 3, 5, 7, 
and 9 costate, the ridge on 3 usually interrupted or depressed beyond the middle, 1, 2, 6, and 8 some- 
times convex. Ventral segments coarsely, closely punctate. Mesosternum flattened between the Coxe, 
sometimes protuberant in front. Femora with a short tooth, and sometimes a small prominence exterior 
to it. Posterior tibie slightly hollowed at the apex within in the g. Tarsal claws with a long, curved 
tooth, the two teeth nearly or quite meeting at the tip. 
Var.? 
The prothorax much more coarsely punctured, the intervening ruge here and there longitudinally confluent ; 
the elytral coste uninterrupted. 
Length 33-5, breadth 1,°,-22 millim. (¢ 2.) 
Hab. Muxico, Tepetlapa, Tierra Colorada, Rio Papagaio, Chilpancingo, Atoyac 
(i. H. Smith), Cuernavaca (Fenyes), Cosamaloapam and Toxpam in Vera Cruz (Sallé),

San Gerénimo (Champion). 
Not rare in Mexico and distributed in various collections under the MS. name of 
C. parvicollis. A small, hirsute, variable species, of ovate form, with the alternate 
elytral interstices costate, the one nearest the suture with a white or fulvous line at the 
base; the rostrum in both sexes short, rugose, and stout; the abdomen coarsely 
punctate; the tarsal claws with a very long, curved tooth. The variety (2) was sent 
from Yucatan with the form selected as typical. In most of the larger specimens the 
femora are distinctly bidentate and the mesosternum protuberant. 
130. Conotrachelus crucifer, sp.n. (Tab. XX. figg. 25, 25a, ¢.) 
Subovate, robust, black, the elytra and legs mottled with rufo-piceous, the antenne and the tips of the tarsi 
ferruginous ; the vestiture close, sparser on the prothorax and under surface, fulvous, intermixed with 
white, the prothorax with an angulate white line on each side of the disc (enclosing a somewhat 
cruciform patch), bifurcating posteriorly, and the elytra each with a broad, dense, oblique, white fascia 
extending from a little below the shoulder to near the suture and a short white streak at the base of the 
third interstice, the femora biannulate with white; the elytra also with scattered, short, pallid, semierect
