1. Xyleborus godmani, sp.n. (Tab. VII. figg. 10; 104, apex of elytra.) 
Fem. Oblongo-ovalis, sat nitida, parce breviter pilosa, nigra, antennis pedibusque fuscis; prothorace amplo, 
convexo, subtransverso, margine apicali tuberculis prominulis ornato, dorso gibboso, post medium punc- 
tato; elytris prothorace sublongioribus, a medio oblique retusis excavatis, indistincte lineato-punctatis, 
interstitiis multipunctatis et posterius seriato-tuberculatis, ambitu excavationis in parte superiore utrinque 
bispinato, spinula superiore prope suturam parva acuta, altera antemediana magna, obtusa. 
Long. 4°3 millim. 
Female. Oblong-oval, somewhat shining, black. Head large, finely reticulate, dull, the front convex, with 
moderately deep punctuation and with a median sulcus towards the vertex, continued to the mouth as an 
indistinct smooth line in the middle of which is a subelevated shining patch ; mouth fringed with fulvous 
hair; eyes small, oblong, flat and deeply emarginate in front; antenns fusco-piceous. Prothorax 
ample, convex, rather broader than long, hind margin transverse, impressed on each side, hind angles 
obliquely rounded, sides nearly straight and parallel behind, gradually curving in front into the broadly 
rounded apical margin, which has five prominent tubercles in the middle and is subsinuate on each side; 
surface with a median transverse obtuse elevation produced obliquely backwards at the sides, sub- 
glabrous, asperate anteriorly, its hinder half not strongly shining, closely reticulate and moderately 
punctured. Scutellum triangular. Elytra as wide as the prothorax and about one-fourth longer, 
subtruncate at base, the humeral calli not prominent, the sides gently rounded, narrowed about the 
posterior fourth and then somewhat abruptly inflexed to the obtuse apical margin ; surface subcylindrical, 
impressed round the base and obliquely excavate from the middle to the apex, with indistinct rows of 
minute punctures ; interstices flat, transversely wrinkled and finely multipunctate, apex of the inner with 
one or two, of the outer with several, spinous setiferous tubercles: apical excavation longitudinal 
oval, deeply impressed, transversely rugose and finely punctured, the sutural margins narrowly raised ; 
side-borders prominent and callose above the lower third, rather sharp below, margined by the interstitial 
tubercles, and armed each with two spines, the first small, near the suture at the apex of the second 
interstice, the second at the anterior extremity of the callosity, large, directed backwards, obtuse and 
cylindrical, terminated by a short bristle. Underside piceous, Legs fuscous, the tibie thickly fringed, 
finely and obsoletely serrate ; tarsi normal. 
Hab. Panama, Bugaba (Champion). 
One example. This and the four following species are among the most distinct 
forms in the genus, and are allied to X. insignis, Kichh. In X. godmani there are 
three series of tubercles outside the large spines on the elytra, their terminal members 
constituting the serrate tubercles which margin the excavation ; these series, so far as 
their position can be identified, are on the fourth, fifth, and sixth interstices.
