XYLEBORUS. 205 
Female. Oblong-ovate, slightly shining, yellow testaceous (possibly immature), covered with close upstanding | 
fine pubescence. Front subconvex, finely punctured, scantily pubescent. Prothorax semi-elliptic, about 
as long as broad, widest just behind the middle, the sides curved throughout, more strongly in front, the 
apex subcircularly rounded, with several prominent tubercles in the middle, hind angles obtuse but not 
rounded, the base subtruncate ; disc convex, very obsoletely elevated in the middle, asperate in front, the 
posterior half with rather close, moderately fine piliferous punctures, their interspaces reticulate, the 
median smooth line very narrow. Scutellum small, rounded triangular, infuscate. Elytra narrower at 
base than the prothorax, and one-third longer, widest about the middle, the shoulders obtusely rounded, 
the sides rounded throughout, more strongly and very obliquely towards the apex, which is almost 
acuminate ; surface longitudinally convex, becoming declivous about the middle, with indistinct rows of 
shallow punctures, interstices with close irregular very fine piliferous punctures; declivity convex, not 
more opaque, more densely pilose, the hairs arising from minute interstitial granules, with obsolete rows 
of punctures, and feebly striate on each side of the suture. Underside, antenne, and legs pale 
testaceous. 
Hab. Guatemata, Rio Naranjo (Champion). 
The head is depressed and not properly visible in the single specimen; this has not 
been recarded to allow of a close examination being made of the head and underside 
for fear of damaging the delicate and characteristic pubescence. 
The species is a near neighbour of X. capucinus, but is smaller, more slender, with 
closer and more erect pubescence ; the prothorax is relatively longer, not so distinctly 
gibbous, and the marginal tubercles are finer and less numerous; the declivity of the 
elytra is more gradually expressed, less opaque, and with much finer granulation. 
13. Xyleborus gilvipes, sp. n. 
Fem. Oblonga, piceo-nigra, pedibus dilute testaceis, erecte pilosa; prothorace lateribus obtuse, apice fortius 
rotundato, dorso omnino granulis posterius minus confertis exasperato ; elytris prothorace minus sesqui- 
longioribus, setis alternatim longioribus et brevioribus seriatis instructis, lineato-punctatis, interstitiis 
paullo subtilius uniseriatim punctatis post medium seriato-tuberculatis, apice sat fortiter declivi, infra 
marginato, parum convexo, interstitio 2° impresso obsoletius tuberculato. 
Long. 2°3 millim. 
Female. Oblong, piceous-black, with erect pubescence. Front convex, dull and closely reticulate, with fine 
subaciculate punctuation and a shining median carina, interrupted near the vertex, pubescence short, 
sparse; antennae testaceous. Prothorax as broad as long, suborbicular, but with the sides more strongly 
rounded before than behind the middle, hind angles obtuse, the basal margin subtruncate; surface convex 
with a very indistinct median transverse elevation, dull, entirely asperate, more finely and sparsely over 
the basal half. Scutellum small, rounded triangular. Elytra a little narrower than the prothorax at its 
widest, and one-third longer, truncate at the base, the shoulders obliquely rounded, the sides nearly 
parallel, not narrowed before the obtusely rounded and sharply margined apical border ; surface cylindric 
towards the base, strongly but not abruptly declivous behind the middle, moderately shining, with regular 
rows of fine punctures bearing minute sete, the sutural row not impressed, interstices flat with single 
rows of finer and more numerous punctures bearing long and nearly erect sete, and of small tubercles 
behind the middle; declivity slightly convex, with the sutural stria subimpressed, and the second 
interstice impressed and more finely tuberculate than the first or third. Underside piceous-black, the 
abdomen shining and subimpunctate. Legs rather pale testaceous, the knees darker; tibiee very finely 
dentate.
