XYLOCLEPTES.—DRYOCGETES. 189 
One species has been found in Central America; or two if Zomicus concinnus be 
referred to this genus. 
1. Xylocleptes chiriquensis, sp. n. 
‘Oblongus, subnitidus, longe parce pilosus, ferrugineus, prothoracis disco transverse subelevato, antice asperato, 
postice sparsim distincte punctato; elytris subtiliter lineato-punctatis, ad suturam impressis, ad apicem 
retusis, ambitu retusionis subtuberculato et spina unica prope suturam instructo. 
Long. 2°5—2°7 millim. 
Fem. Spina retusionis minore, tuberculiformi. 
‘Oblong, somewhat shining, ferruginous, clothed with rather scanty long hairs. Front of the head shining, 
feebly punctured, pubescent. Antenne: normal, ferruginous. Prothorax oblong-ovate, the base very 
slightly rounded, the posterior angles rounded, the sides elliptically rounded and slightly contracted 
towards the apex, which is more obtuse and appears subcrenate ; surface with a slight median transverse 
elevation, behind which is an obscure impression on either side, its anterior half rather finely asperate, 
the posterior half shining, with distinct scattered punctures, the median smooth line obsolete or very 
narrow. Elytra cylindrical, one-third longer than the prothorax, with slightly oblique basal margins, 
the shoulders rounded rectangular, the sides parallel to near the apex, then narrowed, the apex itself 
obtuse ; surface impressed along the suture, finely lineato-punctate, the interstices flat, punctured in rows 
which are only separable from those of the strie by their not bearing hairs; apex retuse, its margin 
subcircular, acute, with one or two small tubercles, and terminating above near the suture in a spine 
which is larger and more pointed in the male than in the female, fundus concave, shining, punctured, 
the suture subelevated. Underside and legs ferrugineo-testaceous, the former finely punctured and 
pubescent. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Three examples. ‘This species is quite closely allied to X. dispinus, but can be 
separated by the rather smaller size, the absence of a wide smooth median line on the 
prothorax, the closer proximity of the apical spines in the male, the punctuation of 
the fundus, and the absence of any distinct emargination at the apex of the suture. I 
have assumed that the distinct difference in the size of the apical spines is sexual ; the 
largest example is the one with the smallest spines. 
DRYOCCETES. 
Dryocetes, Hichhoff, Berl. ent. Zeitschr. 1864, p. 38; Rat. Tom. p. 283 ; Leconte, Rhynch. N.

The species of this genus are at present somewhat less numerous than those of 
Tomicus, but this possibly may be reversed in course of time. Of tropical forms, a few 
are known from Africa, Ceylon, the Malay region, and Tropical America, but the generic 
characters are not beyond doubt in all cases. Dryocwtes approaches Coccotrypes and 
Xyleborus, and it is difficult to refer one or two species among these genera to their 
proper position. In case of doubt, the maxillary armature will at once serve to 
distinguish Dryocetes from the other genera.
