206 RHYNCHOPHORA. 
truncate, and not half the size. The complete asperation of the prothorax is very 
nnusual in the genus; from the other described species possessing this character it 
can be differentiated by the non-impressed rows of punctures on the elytra. 
14. Xyleborus exaratus, sp. n. 
Fem. Subcylindrica, sat nitida, piceo-ferruginea, postice obscurior, erecte pilosa ; prothorace latitudine 
longiori, subelliptico, dorso mox post medium tumidulo, posterius fortiter punctato, piloso ; elytris haud 
profunde punctato-striatis, punctis magnis crenatis, interstitiis convexis irregulariter lineato-punctatis, 
setosis, in apice fortiter convexe declivi rugatis et subtuberculatis. | 
Long. 4°2 millim. 
Female. Subcylindric, moderately shining, deep ferruginous, infuscate posteriorly, with uniform short erect 
pubescence. Front somewhat flattened, with the epistoma and a median longitudinal line subelevated, 
reticulate and punctured at the sides, the pubescence and oral fringe scanty; eyes large, broad, flat, 
narrowly emarginate in front; antenne testaceous-brown. Prothorax longer than broad, widest about 
the basal third part, its hind-margin subconvex, the hind angles obtuse, not rounded, the sides nearly 
straight behind, elliptically curved from behind the middle to the apex; surface obtusely elevated 
behind the middle, subfoveolate on either side within the hind angles, anteriorly asperate, more finely 
before the elevation, posteriorly with strong and rather close piliferous punctures, deeper towards the 
sides, interspaces moderately shining, subreticulate. Scutellum small, convex, rounded, triangular. 
Elytra rather less than one-half longer than the prothorax, and a little wider at the base, the margin of 
which is bisinuate, shoulders rounded rectangular, the sides subparallel, a little widened behind the 
middle and then narrowed, the apex strongly and rather obliquely rounded ; surface subcylindric to the 
hinder third, then obliquely but rather strongly declivous and convex, with shallow strie, crenate with 
large punctures, and deeper posteriorly ; interstices convex, with finer setigerous punctures in single 
rows, irregular from the base to the middle, and incompletely biseriate on the 2nd and 4th, more convex 
behind, with single series of small close tubercles ; apical margin not acutely carinate. Underside and 
legs ferruginous, the abdomen with longish pubescence. 
Hab. Paxama, Bugaba (Champion). 
A single example of this distinct species was taken. In aspect it is rather like a 
Dryocetes, the characteristic gibbosity of the prothorax being slight and its basal 
portion more strongly punctured than usual. 
15. Xyleborus interpunctatus, sp. n. 
Fem. Cylindrica, sat nitida, piceo-ferruginea, densius erecte pilosa; fronte villosa; prothorace latitudine sub- 
longiore ; apice fortiter rotundato, dorso medio indistincte gibboso, posterius sat dense punctato; elytris 
striato-punctatis, interstitiis 1°, 3°, 5°, 7° uniseriatim, ceteris irregulariter biseriatim punctis piliferis 
notatis, apice fortiter convexe declivi utrinque tuberculis 2 parvis prope suturam munito, 
Long. 3°5 millim. 
Female. Cylindrie, rather shining, piceous-red with dense erect pubescence. ‘Front flattened, rugulose, with 
rather thick villous pubescence ; antenna fusco-testaceous. Prothorax rather longer than broad, widest 
behind, slightly narrowed anteriorly, truncate at base, the hind angles obtuse, the sides very feebly 
curved to before the middle, gradually inflexed in front to the strongly rounded apex; surface 
obtusely and subtransversely gibbous in the middle, with erect pubescence, rather dense and long at the 
apex and sides, scanty over the base, asperate in front, the basal half shining, with moderately strong 
punctuation, weaker towards the middle, and nearly absent over the median line. Scutellum small, 
rounded. Elytra as wide at base as the prothorax and nearly one-half longer, truncate at base, the 
shoulders rectangular, not callose, the sides subparallel to the apex, then abruptly inflexed, the apical 
margin therefore subtruneate but acutely carinate ; surface cylindric, its posterior fourth strongly but
