520 CLASS VIII. 
Family LVII. Xylophaga nob. (Genera from the family of the 
Xylophagi Larr., Ptiniores and Xylotrogé ejusd.). Antenne fili- 
form, sometimes serrate or pectinate (at least in males), in others 
terminated abruptly by larger joints. Mandibles horny, short, den- 
tate. Maxille bilobed. Palps filiform or thicker towards the 
extremity, short. Body cylindrical or oyal. Head, as to the 
greatest part, mostly received in thorax. 
Bostrichus Gnorrr. (Apate Fapr.). Antenne with ten joints, 
club triarticulate, perfoliate. T'arsi with joints simple, first very 
small, scarcely distinguishable. Thorax gibbous. 
Sp. Bostrichus capucinus, Dermestes capucinus L., GEorrroy Ins. 1. Tab. 
5, fig. 1, Dumérin Cons. gén. s. 1. Ins. Pl. 17, fig. 1, RataeBure Forst- 
Ins. 1. Tab. X. fig. 14, &c. 
Psoaw FABR. 
Dysides PERTY. 
Cis LATR. 
Anobium Fapr. (Ptinus L.). Antenne 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 Inuie., Anobium pertinax FABR., PANZER Deutschl. Ins. 
Heft 66, Tab. 5; 14—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 RaTzE- 
BuRG Forst-Ins. 1. Tab. 1. 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, 
Uhorloge 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. 
Comp. on the German species of this genus Sturm Fauna, Ins. X1, 1837, 
s. 98—244. The intestinal canal of Anobd, striatum is described and figured 
by Léon Durour, Ann. des Se. nat. XIv, 1822, pp. 219—222, Pl. XII. 
Dryophilus CuEvrou. With three last joints of antenne cylindrical, 
very long, slender. 
Sp. Anobium pusillum GyYLLENH., Dryoph. anobioides CHEVROL, GUERIN
