punctato; elytris a basi convexis, subconfuse punctatis, seriato-setosis, declivitate utrinque sub- 
impressa, 
Long. 1:9 millim. 
Fem. Oblonga, sat nitida, breviter erecte pilosa, nigra vel fusca, elytris nonnunquam postice dilutioribus ; 
prothoracis apice rotundato, crenato, dorso posterius vage punctato ; elytris post medium oblique rotundatis, 
lineato-punctatis, interstitiis seriato-pilosis; declivitate obliqua, retusa, supra utrinque serie 2 aut 3 
spinarum, et spina in ambitu inferiore armata, spinis 4 ultimis majoribus. 
Long. 2°3 millim. 
Male. Oblong, shining, fusco-piceous, the elytra lighter posteriorly. Front moderately convex, dull, sub- 
glabrous, obsoletely punctate; antenne testaceous, the club narrow. Prothorax as long as broad, the 
sides and apex gently and separately rounded, therefore subquadrate but with rounded anterior angles, 
hind angles obtuse ; disc depressed, but uniformly subconvex, not gibbous, sparingly and finely punctate, 
the punctures subasperate in front but scarcely closer, pubescence rather long, thin, the median line just 
perceptibly elevated behind, interspaces reticulate towards the base. Scutellum minute, subtriangular. 
Elytra narrower at base than the prothorax and one-half longer, shoulders obtuse, the sides gently 
rounded, narrowed behind, apex obtusely rounded; surface longitudinally convex, declivous behind the 
middle, finely rugulose, with shallow, rather remote punctures in irregular rows, sete erect, stout, 
regularly placed, closer and stronger behind the middle; declivity with a shallow irregularly punctate 
impression on each side. Underside fuscous, legs testaceous-brown. 
Female. Oblong, moderately shining, black, piceous or fuscous (immature). Head reticulate, the front convex, 
rather closely punctured and shortly pubescent. Prothorax narrower than in X. ferox, more parallel- 
sided, the hind angles less obtuse, the discal elevation less distinct. LElytra less narrowed posteriorly, 
with the sides subparallel to behind the middle, rather less distinctly punctured in rows, the sete closer 
and more conspicuous, especially on the declivity, where they are short and subsquamous; the four spines 
smaller and shorter, the superior pair placed farther back and more laterally, and preceded on the third 
interstice by one or two smaller spines, rather larger than the marginal tubercles on the apex of the fifth, 
interstice; fundus of the impressed area less shining, more closely punctate. Underside piceous or 
fuscous, legs fusco-testaceous.

Six specimens were taken by Mr. Champion; I have a series of uncertain Neotropical 
origin from tobacco-refuse. The single male, from Zapote, has the abdomen curiously 
constructed, but its appearance may perhaps be due to distortion. The first four 
segments are prominent in the middle line, their apical borders being strongly raised 
and V-shaped, reaching farther back at the sides than in the middle; the last seement 
is long and rather narrow, impressed in the middle, elevated and callose laterally. 
The female is very like that of X. ferox, but the elytral spines are only about as long 
as their width at the base, whereas in X. ferox they are at least twice as long. If 
examples be looked at above and from the front, the anterior pair of large spines is 
clearly seen in AX. spinulosus to form the last of a short series of two to four spines on 
the third interstice, while in X. feror they are preceded only by one or two small 
marginal tubercles which cannot be confounded with this series. In consequence this 
pair of spines appears in X. ferow to stand within, in X. spinulosus to stand on the 
lateral margin of the declivity. One example from San Gerédnimo and that from 
Grenada have these spines very much reduced in length, without accompanying 
specific distinctions.
