Juan in Vera Cruz (Hoge), Ojo Chico and Jalapilla (fide Chevrolat 1). 
Apparently not uncommon in the State of Vera Cruz. Distinguishable from 
H. elegans and other allied forms by the broad, sinuous, white vittee not reaching the 
apex of the elytra, though sometimes extending along the suture to near the tip. 
The head is deeply foveate between the eyes, which are narrowly separated. The 
antenne are inserted before the middle of the rostrum, which is longer in the female 
than in the male; the first and second joints of the funiculus are subequal in length. 
The venter is broadly depressed down the middle in the males, The sculpture of the 
prothorax and elytra is variable.

A very variable insect, but always separable from the Mexican H. cruciatus by the 
sinuous whitish or pale ochreous vitte extending to the apex of the elytra, and more 
or less surrounding the subapical callosities, which are bare at the summit, as is also 
the suture. In both species the elytral vittze are sometimes broadly interrupted 
beyond the middle, and often show a tendency to become broken up into spots; and 
in H. elegans they are sometimes again interrupted (as described by Guérin) before the 
apex, so as to leave an isolated apical spot. The fifteen specimens from Cerro Zunil 
(fig. 13) have the inner and outer margins of these stripes much less indented, and the 
subapical callosities indicated by a large bare spot. Amongst our long series from 
Chiriqui, one only (the insect obtained from Boucard) shows the broad depression on the 
disc of the prothorax before the base, mentioned by Guérin, and exhibited in the South- 
American individuals before me; others, again, from the same district, are much less 
elongate. The rostrum is curved and stout. The antenne are inserted before the middle 
in both sexes, but nearer the tip in the males than in the females. Length (excluding 
rostrum) varying from 9-17 millim. 
3. Hilipus albopictus, sp. n. (Tab. I. fig. 14, ¢.) 
Very like H. cruciatus, Chevr., but differing as follows:—The white markings much reduced in extent—the 
humeral patch on the elytra represented by a narrow stripe extending forwards from the second one, 
and forming a continuation of the prothoracic vitta, which is also much narrowed before the middle, the
