1. Hylocurus cancellatus, sp. n. (Tab. VII. fig. 22, 3.) 
Cylindricus, subnitidus, parce pilosus, niger vel piceus; prothorace oblongo, dorso pone medium granulato, 
lateraliter rugose punctato; elytris fortiter crenato-striatis, striis posterius profundioribus. 
Long. 2°6-3'1 millim. (¢ 9.) 
Mas, Prothoracis margine antico tuberculato; elytris postice dilatatis, circulatim retusis, interstitiis in ambitu 
retusionis tuberculato-carinatis, 3° in declivitate obliqua 4-tuberculato. | 
Fem. Prothoracis margine antico simplici; elytris ad apicem convexe declivibus, interstitio 3° ad apicem 
subtilius tuberculato. 
Cylindric, moderately shining, black or pitchy-black. Front subconvex above, with close rugose punctuation, 
transversely subcarinate in the middle, the carina conjoined with an elevated smooth median line 
reaching the mouth ; epistoma impressed on either side, bearing a tuft of fulvous hairs. Prothorax longer 
than broad, truncate at base, with the hind angles rounded; the sides (¢) nearly straight behind, 
incurved and slightly narrowed at the middle third, the apex broadly rounded, margined with small 
tubercles ; sides ( 2 ) more distinctly constricted in front, the apex more strongly rounded, not tuberculate : 
surface depressed behind an indistinct antemedian transverse elevation and subelevated at the base, 
rufescent and scantily hairy towards the apex, the anterior half asperate with small granules, closer and 
stronger in the male, the basal half rugosely punctate at the sides, finely granulate towards the middle, 
the granules weaker over the median line, the interspaces closely reticulate. Scutellum small, sub- 
triangular, punctured. LElytra (¢) one-half longer than the prothorax and as wide at the base, their 
basal margins feebly rounded, the shoulders roundéd, not callose, the sides straight, divergent, the hind 
margins oblique, straight, produced at the suture into a common mucro; surface cylindric, punctate- 
striate, the punctures deeply impressed, becoming very large and sometimes confluent behind, interstices 
narrow, convex, shining, with indistinct punctures, behind costiform, the coste much broken and. 
conjointed with the interspaces of the strize to form an irregular elevated reticulum, their extremities 
forming a series of short angulate tubercles round the declivity, fringed with fine hairs; declivity oblique, 
convex, strongly punctured in substriate rows, the sutural interstice finely tuberculate, the third with 
four, the fifth with one or two pointed setiferous tubercles. Elytra (2) relatively longer, glabrous, 
subparallel to the oblique rounded hind margins, the striz less coarsely punctured, deeper before the 
declivity, which is strongly punctured but not striate, the interstices gradually declivous, the third and 
* T have not seen this Venezuelan species, which is placed by the published characters.
