406 RHYNCHOPHORA. 
apex smoother, the antenne in the ¢ inserted close to the tip and in the 2 at about one-fifth from it. 
Prothorax transverse, rounded at the sides, narrowed and constricted in front, deeply bisinuate at the 
base ; coarsely, densely punctate, the punctures here and there confluent, the disc carinate down the 
middle from the base to the apex. Elytra oblong, slightly constricted beneath the humeri and narrowing 
thence to the apex, the base strongly sinuate, the humeri rounded; coarsely seriate-punctate, the 
interstices closely rugulose, 3,5, 7, and 9 narrowly costate throughout. Ventral segments densely, 
coarsely punctate. Mesosternum flattened between the coxe, protuberant and binodose in front. Legs 
rugosely punctate; femora feebly clavate, unidentate, the anterior pair in the ¢ densely ciliate beneath 
from the tooth to the base ; posterior tibize with a broad, spoon-shaped, chitinous lobe at the apex within 
in the 3, simply unguiculate in the 9; tarsal claws with a moderately long tooth. ' 
Length 6-6, breadth 3 millim. (¢ 9.) 
Hab. Mexico, Ventanas in Durango (Hoge). 
One male and three females. Larger and more robust than C. scoparius, the 
prothorax broader, the male-characters very different. 
118. Conotrachelus compressus, sp. n. (Tab. XX. figg. 20, 20a, ¢ ; 208, 
hind leg, 3.) 
Subovate, rather narrow, robust, shining, black, the antenne and tarsi obscure ferruginous; thickly clothed 
with rather coarse, narrow, yellowish-white scales, which are condensed into small patches on the elytra 
and become finer and more scattered on a large subtriangular space on the disc of the prothorax, the 
vestiture of the metasternum and abdomen very sparse. Head convex, densely punctate, the eyes not 
very widely separated ; rostrum rather slender, curved, a little longer than the head and prothorax, 
seriate-punctate and feebly 5-carinate, bare and sparsely punctate at the tip, the antennee inserted a little 
before the apex, joints 1 and 2 of the funiculus equal in length. Prothorax convex, slightly broader 
than long, narrowed and compressed anteriorly, strongly bisinuate at the base; coarsely, rugosely 
punctate, and carinate down the middle to near the base and apex. Elytra oblong, subtriangular, strongly 
sinuate at the base, about one-half wider than the prothorax, laterally compressed and with the sides 
vertical from the seventh interstice, the humeri rounded ; very coarsely seriate-punctate, the interstices 
closely rugulose, 3, 5, and 7 narrowly costate throughout, and 9 also feebly costate from a little below 
the base. Mesosternum flattened between the cox. Ventral segments sparsely punctate. Femora 
strongly clavate, unidentate. Posterior tibie abruptly excavate and sparsely ciliate at the apex within, 
the apex strongly unguiculate. Tarsal claws with the inner tooth almost as long as the claw itself, 
Length 5-54, breadth 23 millim. (¢.) 
Hab. Mexico, Jalapa (Hége). 
Two males. The laterally compressed elytra, with uninterruptedly carinate alternate 
interstices, the coarse yellowish-white vestiture (which kecomes ochreous on the head 
and prothorax), the rugose, carinate prothorax, the bifid tarsal claws, &c., distinguish 
C. compressus from most of its allies. It has somewhat the facies of the North- 
American C. crategi, Walsh, but has much narrower elytra, a more rugose prothorax, a 
more slender rostrum, &c. 
119. Conotrachelus rubidus, sp.n. (Tab. XX. figg. 21, 21a, 3.) 
Oblong-ovate, robust, opaque, rufo-piceous, the head, rostrum, antenng, and elytra more or less rufo- 
ferruginous, the elytra irregularly nigro-fasciate at and beyond the middle, the legs ferruginous, with the 
femora mottled with black; the vestiture very sparse, ochreous or fulvous, closer on the head, the 
prothorax with a dense, oblique, white line on each side of the disc, the two lines nearly or quite meeting 
in front and extending from the hind angles on to the humeri, the elytra with an irregular white post-
