HILIPUS. 1? 
Var. The elytral spots coalescent and forming a sinuous submarginal vitta (fig. 4). 
Length 123-16, breadth 34-53 millim. (¢ 9.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Found in plenty by myself on the slopes of the Volcan de Chiriqui, the form with a 
few shallow widely-scattered punctures only on the disc of the prothorax predominating. 
The variety, of which a single specimen only was captured, is very like the Costa- 
Rican Z. bivittatus, but has the prothorax more narrowed in front and the coalescent 
spots on the sides of the elytra forming sinuous vitte. The present species is nearly 
allied to H. collectus, from which it may be known by the complete prothoracic vitte, 
and by the elytral spots being concentrated along the outer part of the disc, showing 
no tendency to form oblique fasciz. The specimens with a closely punctured prothorax 
are more shining than the others. 
18. Hilipus bivittatus, sp.n. (Tab. II. fig. 5, 2.) 
Elongate, subcylindrical, moderately shining ; the prothorax and elytra each with a broad submarginal pale 
ochreous vitta, the two vitte not confluent at the apex, the elytra in one specimen (2?) also with two 
detached similarly-coloured spots on the third interstice; the under surface with scattered ochreous 
scales, which are concentrated into small patches towards the sides; the legs and rostrum with narrow 
whitish scales. Head deeply foveate between the eyes, which are rather narrowly separated ; rostrum 
stout, curved, as long as the prothorax, rugosely punctured towards the base, almost smooth at the tip; 
antennee inserted far before the middle of the rostrum, joint 1 of the funiculus slightly longer than 2. 
Prothorax longer than broad, very little narrowed in front, the sides more parallel in the ?; the surface 
coarsely punctured (except upon the space occupied by the vittee), and with indications of a raised central 
line, the flanks rugosely punctured and in one specimen (2) granulate. Elytra elongate, subparallel to 
beyond the middle, at least one-half wider than the prothorax, conjointly rounded at the apex, the humeri 
rounded ; seriate-punctate, the interstices broad and more or less wrinkled transversely. Ventral segments 
1 and 2 with a few scattered punctures, and in the ¢ broadly depressed down-the middle. 
Length, g 13, 2 19; breadth, ¢ 4, Q 6 millim. 
Hab. Costa Rica (Van Patten), Caché (Rogers). 
One pair. The female has the prothorax longer and less narrowed anteriorly than in 
the male, and also much more coarsely and closely punctured. This species is allied to 
H. peplus, Guér., and other South-American forms, from which it may be distinguished 
by its narrower and more parallel shape, the straighter elytral vitte, &c. From 
H. norrisii, Guér. ((=H. chevrolatii and H. bohemant, Guér.), from Colombia, it differs 
in the regularly seriate-punctate disc of the elytra, and the absence of a line of yellow 
scales near the suture, &c. . 
19. Hilipus areolatus, sp. n. (Tab. II. fig. 6, ¢.) 
Elongate-ovate, shining, black or pitchy-black, the rostrum and tarsi sometimes reddish ; the prothorax with 
two lines of ochreous scales on each side, these becoming coalescent at the base and apex and enclosing 
an elongate-triangular space ; the elytra with two zigzag lines of similarly-coloured scales on the disc and 
another down the sutural stria, which are here and there connected so as to enclose large triangular 
spaces, the lines themselves becoming more tortuous at the apex; the rest of the upper surface, as well
