MALACODERMATA. 350 
‘1. Xylographus suillus. (Tab. XIII. figg. 21, 21a.) 
Breviter oblongus, crassus ; prothorace antice angustato, caput sicut cucullo tegente ; nigro-piceus, nitidus, sat 
fortiter crebre punctatus; antennis (clava excepta) testaceis. Long. 2 millim. 
Hab. Guatemata, Teleman (Champion). 
This species and X. porcus are distinguished from any of the Cioide known to me 
by the form of the thorax, which is produced over the head in a hood-like manner, the 
head being comparatively small; when viewed sideways the front of the thorax leaves 
an open space betwixt itself and the head. No horns or tubercles are present, and I 
do not distinguish the sexes. The antenne are ten-jointed; the funicular joints are 
very small and short, the three club-joints transverse and blackish. The punctuation of 
the thorax is fine and close, that of the elytra sparser and stronger. The thorax is 
much deflexed at the sides, and it is entirely margined with a fine raised line. The legs 
are pitchy, a little lighter than the body. Many specimens were obtained in hard 
boleti growths on the trunks of the “ Manaca” palm (Adtalea cohune), in the hottest 
parts of the Polochic valley. 
2. Xylographus porcus. 
Breviter oblongus, crassus; prothorace antice modice angustato, nigro-piceus vel piceus, elytris brunneis, pilo 
tenui parcius vestitus; prothorace crebre, elytris parcius fortiter, punctatis, his ad apicem retusis. 
Long. 1-14 millim. 
Hab. Guatemata, Teleman, Zapote, Pantaleon (Champion). 
A smaller species, and much more coarsely and sparingly punctured than X. suillus ; 
the thorax is similarly formed, projecting very much over the head, the margin is 
entirely bordered by a fine line, except in the immediate front, where it is faintly 
emarginate, and this part is usually reddish. The elytra are not longer than the 
thorax, being scarcely longer than wide, and they are almost setose, the pile being very 
short and stiff. The antenne are proportioned as in X. swillus, and are similarly 
coloured. The smaller specimens are those from Pantaleon. 
Many examples. This species very much resembles a Tomicus, owing to the short 
retuse body and upright hairs. 
3. Xylographus latirostris. (Tab. XIII. figg. 23, 234, 6; 24, 24a, 2.) 
Oblongus, robustus, niger, nitidus; prothorace minute, distincte, elytris minus distincte, subtilissime punctatis ; 
pedibus rufis. Long. 2-2; millim. ¢ Q. 
Mas. Capite antice laminato-elevato, utrinque ante oculos elevatiore ; prothoracis margine antico in laminam 
bene distinctam, recurvatam, margine summo emarginato, elevato. 
Femina. Capite antice laminato-elevato, prothorace mutico. 
Hab. Guatemata, Zapote (Champion).
