520 CLASS VIII. 



Family LVII. Xylophaga nob. (Genera from the family of the 

 Xylophagi LATR., Ptiniores and Xylotrogi ejusd.). Antennae fili- 

 form, sometimes serrate or pectinate (at least in males), in others 

 terminated abruptly by larger joints. Mandibles horny, short, den- 

 tate. Maxillae bilobed. Palps filiform or thicker towards the 

 extremity, short. Body cylindrical or oval. Head, as to the 

 greatest part, mostly received in thorax. 



Bostrichus GEOFFE. (Apate FABR.). Antennae with ten joints, 

 club triarticulate, perfoliate. Tarsi with joints simple, first very 

 small, scarcely distinguishable. Thorax gibbous.

Psoa FABR. 



Dysides PERTY. 

 Cis LATR. 



Anobium FABR. (Ptinus L.). Antennas with eleven joints, the 

 three last larger, the ninth and tenth obconical, the eleventh oval. 

 Body oblong, anteriorly and posteriorly rotundate. Tarsi short, 

 with five distinct joints. 



Sp. Anobium striatum ILLIG., Anobium perfmaxFABB., PANZER Deutschl. Ins. 

 Heft 66, Tab. 5 ; J 2'" long, black-brown with striated elytra. They 

 live in old wood, and render our furniture wormeaten, by small round holes, 

 from which a fine yellow powdered wood falls. The larva lives in these 

 cylindrical passages, and resembles, like that of Apate, the larva of the 

 cockchafer in miniature (see fig. of the larva of Anob. tessellatum in KATZE- 

 BURG Forst-Ins. I. Tab. II. fig. 19, of Apate ibid. Tab. XIV. fig. 33). This 

 little beetle causes a ticking sound in the wood, from which vulgar super- 

 stition derives an unfavourable omen, as appears from the names Todtenuhr, 

 Vhorloge de la mort, Death-watch. Another smaller, red-brown species, 

 Anobium paniceum, Dermestes paniceus L., PANZER Deutschl. Ins. Heft 66, 

 Tab. 6, lives in biscuit, wafers, &c., and sometimes gnaws through the 

 corks of bottles filled with white, sweet wine.

Dryophilus CHEVROL. With three last joints of antennae cylindrical, 

 very long, slender.-
