small tubercles; declivity little convex, not margined below, with the interstices uniformly and rather 
closely tuberculate. Underside fuscous, the legs testaceous.

This little species, of which one example was captured by Mr. Champion, is readily 
distinguished from other Central-American forms by its small size, fuscous-brown 
colour, the alternate rows of longer and shorter hair on the elytra, and the uniform 
tuberculation of the interstices. Its nearest ally appears to me to be X. seriatus, 
Blandf., from Japan, a much larger insect and readily distinguished by the comparatively 
strong punctuation of the basal half of the prothorax and the elytra, which in 
X. intersetosus is so weak as to be with difficulty observable. The latter insect is the 
smallest Xyleborus with which I am acquainted, being as short as, and more slender 
than, the Japanese X. minutus, Blandf.

Mr. Champion has taken a single example, which I refer provisionally to this species. 
‘The description corresponds so aptly as to make a separation impossible without seeing 
the type, which has not been procurable. In this example, however, the elytra are 
parallel-sided almost to the middle and cannot be said to be narrowed from the base, 
as in Eichhoff’s description; the length, 2°4 millim., is also rather greater. 
26. Xyleborus morulus, sp. n. 
Fem. Elongata, cylindrica, sat nitida, parcissime pilosa, piceo-nigra, pedibus brunneo-testaceis ; prothorace 
oblongo, apice rotundato, disco obsoletius transverse elevato, dimidia parte basali punctata: elytris sub- 
tilissime lineato-punctatis, stria suturali omnino non impressa, interstitiis rarius uniseriatim punctatis, 
1° et 3° in declivitate obliqua tuberculatis. 
Long. 3 millim. 
Female. Elongate, cylindric, moderately shining, black, with a slight pitchy tinge on the elytra, with a few 
short hairs at the apex and sides of the prothorax and towards the apex of the elytra. Front subconvex, 
dull, subreticulate, strongly punctured, smoother, but scarcely elevated along the median line; the mouth 
fringed. Prothorax evidently longer than broad, widest at the base, hind angles obtuse, the sides sub- 
parallel to the middle, the apex strongly and regularly rounded; surface with a scarcely discernible ante- 
median transverse elevation, asperate anteriorly, its posterior half shining, evidently but not strongly 
punctured, with a median smooth line. Scutellum small, rounded. Elytra more than one-half longer 
than the prothorax and as wide at the truncate base, shoulders subrectangular, sides parallel, very slightly 
narrowed at the posterior third, the apex subcircularly rounded ; surface cylindric, convexly declivous 
for the apical third, finely lineato-punctate, without a trace of striew, interstices flat, subrugulose, with 
single series of less frequent punctures, larger and smaller in somewhat irregular succession, the larger 
punctures about equal to those of the principal rows, the smaller punctures microscopic; declivity convex 
and shining, rather irregularly and weakly punctured, with five setigerous tubercles on the first, and two 
to four on the third and outer interstices, the second very faintly impressed. Underside pitchy black ; 
legs testaceous-brown.
