prothorax, the outer of which is continued along the humeri in front, the subfasciculate 
vestiture of the elytra, the very stout 5-carinate rostrum, and the rugose unidentate 
femora are the chief characteristics of this species.

This is one of the commonest and most widely distributed Conotracheli in Central 
America. It is easily recognizable by the oval, oblique, dark, bare patch immediately 
before the apex of each elytron, this being bordered internally by an ochreous line; and 
the oblique similarly-coloured line on each side of the disc of the prothorax, the two 
lines not meeting in front and continued down the head and rostrum, and also extending 
backwards on to the elytral humeri. ‘The mesosternum is flattened between the coxe. 
The femora are bidentate. The tarsal claws have a short tooth. The rostrum is 
exceedingly stout, short, arcuate, rugulose and carinate, and very similarly formed in 
the two sexes. ‘The fifth ventral segment is depressed or foveate on each side in both 
male and female. 
Fahreus ! also gives “ North America” as a locality, but the insect is not mentioned 
by Leconte, and probably does not extend north of Mexico.

Subovate, shining, rufo-piceous, the antenna, the apical half of the rostrum, the tibia, and tarsi ferruginous ; 
the vestiture sparse, ochreous, condensed into a sharply-defined oblique line on each side ot the disc of the 
prothorax, the two lines continued forwards on to the head and rostrum and there coalescent, and back- 
wards on to the humeri of the elytra, the latter with a common, broad, curved, ochreous, subapical fascia, 
which extends down the suture to the apex and nearly encloses an almost bare, oblique, apical patch on 
each elytron, the clothing of the under surface whitish, the femora with an ochreous ring. Head densely 
punctate, foveate between the eyes, finely carinate in front; rostrum moderately stout, thickened a little 
towards the base, feebly curved, nearly twice as long as the prothorax, rugulosely punctate and shallowly 
sulcate, unicarinate at the base, the apical half bare and rather sparsely punctate, the antenne inserted 
slightly beyond the middle, joint 2 of the funiculus shorter than 1. Prothorax broader than long, 
narrowed and feebly constricted in front, deeply bisinuate at the base; densely, rugulosely punctate, the 
narrow raised interspaces oblique or crescentiform. lytra narrowing from about the basal fourth, 
slightly constricted below the humeri, which are obliquely truncate in front; coarsely seriate-punctate, 
the interstices densely rugulose, 3, 5, 7, and 9 sharply costate, the ridge on 3 and 5 abruptly twice 
interrupted, the median elevation on 3 prominent, Mesosternum flattened between the coxe. Ventral
