DRYOCGETES. 191 
slightly flattened on each side of the suture, shining, more closely pubescent, its punctuation weaker. 
Underside black, pubescent, legs piceous. 
Hab. Mexico, Jalapa (Hége). 
‘Iwo specimens. More elongate than J. coryli (Perr.), which it somewhat resembles ; 
the prothorax is, however, more ample and wider behind; the punctures of the elytra 
are closer and in more regular rows, and the apex is less strongly and more widely 
impressed on either side. From D. limbatus it can be separated by its more elongate 
form, black colour, and the absence of impressed strie on the elytra. The smaller 
‘example shows certain differences in the shape of the prothorax, which is less narrowed 
towards the base, and in the punctuation of the elytra, which is relatively a little coarser 
and less close. 
3. Dryocetes maurus, sp. n. 
Oblongus, subnitidus, niger, pedibus piceis, antennis tarsisque testaceis, parce pilosus ; prothorace subelliptico, 
anterius angustato, dorso granulato, linea media levi; elytris conferte striato-punctatis, interstitiis 
angustis, rugulosis, rarius punctatis, posterius seriato-pilosis, declivitate leviter deplanata. 
Long. 2 millim. 
Oblong, not elongate, slightly shining, black. Head flattened in front, closely punctured towards the sides, 
thinly punctured and more shining towards the middle, pubescence scanty except along the mouth ; antenne 
testaceous-brown, club suboval, the sutures visible on the outer face. Prothorax not longer than broad, 
widest near the base, narrowed towards apex, the sides little rounded behind, more strongly in front, 
apex obtusely rounded, hind angles obtuse; surface gradually and convexly declivous in front, sub- 
glabrous, granulate, the granules finer and less close behind, median line very narrow, not shining. 
Seutellum very small, triangular. Elytra more than one-half longer than the prothorax, their sides 
nearly straight to the middle, then gradually rounded, apex obtuse ; surface with close shallow strie of 
rounded punctures, the sutural stria not deeper, interstices narrow, transversely rugose, punctured rather 
more remotely than the striz, the punctures towards the apex and on the two first interstices tending to 
be replaced by minute granules bearing rather short pale hairs; declivity convex above, very slightly 
flattened from side to side. Underside black; legs piceous with lighter tarsi, the tibie rather strongly 
expanded before the apex. 
Hab. Guatemata, El Tumbador (Champion). 
This species is represented in our collection by a single example, which corresponds 
in many respects with Eichhoff’s description of D. carbonarius (Ferr.), from Cuba; but 
is distinguishable by the articulate antennal club, the piceous legs, and the non-retuse 
apex of the elytra, the flattening of which is very slight and has no determinate 
limits. 
Subgroup IT. XYLEBORI. 
Xyleboride, Eichhoff, Rat. Tom. p. 308. 
As previously mentioned, this subgroup includes two out of the three genera of 
Fichhoff’s subfamily, Gnathotrichus being placed elsewhere. Limited, therefore, to 
Coccotrypes and Xyleborus, so far as Central-American genera go, it forms a very 
distinct and well-defined association, one of the most striking characters of which is
