CONOTRACHELUS, 397 
and white, the elytra with a dense ochreous patch on each shoulder, the clothing of the under surface 
very sparse and white. Head densely, finely punctate; rostrum exceedingly stout, arcuate, about as long 
as the head and prothorax, rugulosely punctate, feebly carinate, and squamose, bare and sparsely punctate 
at the tip, the antenne inserted near the apex, joints 1 and 2 of the funiculus subequal in length. 
Prothorax transverse, constricted and abruptly narrowed in front, emarginate in the centre at the apex, 
and deeply bisinuate at the base; the surface very uneven, coarsely, closely punctate, feebly carinate 
towards the apex, strongly, obliquely nodose on each side of the shallow median groove before the 
middle, the elevations followed by a deep oblique sulcus. Elytra abruptly constricted below the rounded 
humeri and narrowing from a little beyond this to the apex, strongly sinuate in front; coarsely seriate- 
punctate, the interstices 3,5, 7, and 9 very sharply costate, the ridge on 3 and 5 twice, and that on 7 
once, abruptly interrupted, 10 with a short ridge at the base. Mesosternum flattened between the coxe, 
bituberculate in front. Ventral segments very sparsely, finely punctate. Legs rather short; femora 
strongly clavate, sharply unidentate, the anterior pair with a small prominence placed at some distance 
exterior to the tooth; tarsal claws with a moderately long tooth. 
Length 5-53, breadth 23-24 millim. (<¢.) 
Hab. GuateMaLa, Aceituno (Champion). 
Three specimens, probably all males, found near the city of Guatemala. The 
dense white vestiture of the head, the coarsely punctured, binodose, obliquely bisulcate 
prothorax, the very prominent elevations on the disc of the elytra, the dense ochreous 
patch on the shoulders of the latter, the exceedingly stout rostrum, &c., will enable 
this species to be easily identified. The anterior femora only, which are unusually 
stout, have a small prominence exterior to the usual tooth. Viewed in profile, the 
prothorax projects broadly forwards over the head. 
101. Conotrachelus cordatus, sp.n. (Tab. XX. figg. 9, 9a.) 
Ovate, dull, black, more or less variegated with rufo-piceous, the antenne, and the legs in part, ferruginous ; the 
vestiture close, brownish, slightly intermixed with white on the prothorax and at the apex of the elytra, 
the latter with a short white streak on the third interstice beyond the middle, that of the head dense and 
ochreous in colour, the femora faintly biannulate with whitish, the very sparse squamosity of the under 
surface also white. Head densely punctate, depressed between the eyes; rostrum exceedingly stout, 
about as long as the head and prothorax, arcuate, slightly swollen at the base above, rugulosely punctate 
and feebly tricarinate, suleate at the sides, the apical portion bare and sparsely punctate, the antenns 
inserted towards the tip, joint 2 of the funiculus a little shorter than 1. Prothorax nearly as long as 
broad, narrowed and strongly constricted in front, deeply bisinuate at the base; the surface uneven, 
rugosely punctate, confluently binodose at the middle of the disc and obliquely sulcate behind this, the 
two sulci sometimes separated bya short carina. LElytra nearly twice as wide at the base as the prothorax, 
cordate, strongly sinuate at the base, flattened on the disc anteriorly ; coarsely seriate-punctate, rugulose, 
the interstices 3, 5, 7, and 9 sharply costate, the ridge on 3 and 5 twice interrupted. Mesosternum 
flattened between the coxe, sometimes a little swollen on each side anteriorly. Ventral segments 
shining, very sparsely, finely punctate, 5 shallowly foveate at the apex in the g. FEemora clavate, 
unidentate. Tarsi rather slender, the claws with a short tooth. 
Length 31-34, breadth 1,%-2,'5 millim. (¢ 9.) 
Hab. Mexico, Toxpam in Vera Cruz (Sallé); Guaremana, Cerro Zunil (Champion) ; 
Panama, Bugaba, Volcan de Chiriqui (Champion). 
Found in numbers in Chiriqui. This is one of several small species with a narrow, 
rugose, uneven prothorax, cordate, somewhat flattened elytra, and the rostrum very
