CONOTRACHELUS. 438 
middle, joint 2 of the funiculus a little longer than 1 and about the length of 3-5 united. Prothorax a 
little broader than long, conical, the apex produced and tubulate, the base strongly bisinuate ; coarsely, 
rugosely punctate, with the intervening ruge minutely punctate, finely carinate down the anterior half. 
Hiytra subtriangular, rather long, sinuate in front, the humeri broadly rounded; coarsely, seriate- 
punctate, the punctures rounded, deep, and each bearing a minute scale, the interstices finely rugulose, 
7 and 9 costate throughout, 3 also costate towards the apex, and 5 from the middle onwards, Anterior 
cox subconical. Intermediate coxe widely separated. Mesosternum concave, depressed to below the 
level of the metasternum, the latter also slightly depressed along the middle. Ventral segments 2-5 
very sparsely, minutely punctate. Legs stout; femora sulcate beneath, clavate, and sharply unidentate ; 
tarsal claws with a moderately long tooth. 
Length 7}, breadth 43 millim. (¢@.) 
Hab. Mexico, Motzorongo in Vera Cruz (Flohr). 
One specimen. The conical, rugose prothorax, the anteriorly abbreviated dorsal 
coste of the elytra, the concave mesosternum, the elongate second joint of the funiculus, 
&c., readily distinguish this species. 
167. Conotrachelus serpentinus. (Tab. XXI. figg. 19, 19a; 194, hind 
leg, 3.) 
Conotrachelus serpentinus, Boh. in Schénh. Gen. Cure. iv. p. 402’. 
Conotrachelus koltzei, Faust, in litt.’ 
Oblong, robust, shining, black or piceous, the antenne and the tips of the tarsi ferruginous; the vestiture 
long, rather coarse, somewhat close, rufo-ferruginous or brown, in some specimens slightly intermixed 
with white on the alternate elytral interstices, legs, and under surface, and condensed into a small spot 
at the hind angles of the prothorax and on the front of the humeri. Head densely, rugulosely punctate ; 
rostrum (¢) moderately stout, curved, more than one-half longer than the prothcrax, punctate-striate 
at the sides, carinate down the middle towards the base, bare and sparsely punctured at the apex, ( 2 ) not 
so stout, longer, smoother, and more curved, the antenne in the ¢ inserted at about one-fourth and in 
the © at one-third from the tip, joint 2 of the funiculus as long as or longer than 1, about the length of 
3-5 united. Prothorax transverse, subconical, moderately constricted in front, deeply bisinuate at the 
base ; densely, rugulosely punctate and finely carinate. Elytra elongate-subtriangular, deeply sinuate at 
the base, the humeri rounded; coarsely seriate-punctate, the punctures subquadrate and closely placed, 
the interstices narrow, rugulose, 3, 5, 7, and 9 costate, the ridge on 3 and 5 each becoming evanescent 
before the middle. Meso- and metasternum flattened and depressed between the intermediate coxe, the 
metasternum also hollowed in the middle behind. Ventral segments very sparsely, coarsely punctate. 
Femora clavate, unidcntate, suleate beneath. Anterior tibiae hollowed on the outer edge towards the 
apex. Tarsal claws with a moderately long tooth. 
Length 7-73, breadth 33-33 millim. (¢ @.) 
Hab. Mexico (Koltze, in Mus. Dresden), Cordova (Sallé), Jalapa (Hége) ; Costa Rica, 
Irazu (Rogers); Panama, Volcan de Chiriqui, David, Tolé (Champion).—AnTILLES, 
Cuba 1, Jamaica (Gosse, coll. Sharp). 
Eight specimens, agreeing with one from Cuba in the British Museum, and also 
with the type communicated by Dr. Sjostedt. C. serpentinus approaches C. conicicollis, 
but it is narrower, and has a more transverse, anteriorly constricted, less rugose 
prothorax ; the mesosternum is not depressed below the level of the metasternum ; 
the tarsal claws have a longer tooth, &c. ‘The second joint of the funiculus is at least 
as long as the first.
