The foregoing bibliography is not complete, as only the more im- 

 portant articles are cited. 



Male. — Elongate, slightly depressed, black, except elytra and four 

 posterior abdominal sternites, which are red; antennae, palpi, labrum, 

 and tarsi reddish brown. 



Head much narrower than pronotum, uneven, sometimes with a 

 more or less distinct longitudinal groove on vertex; coarsely, con- 

 fluently, rugosely punctate, sparsely clothed with long, erect, incon- 

 spicuous hairs. 



Pronotum slightly wider than long, widest near middle, strongly 

 deflexed on apical half; sides broadly rounded, more strongly con- 

 verging anteriorly than posteriorly ; surface uneven, coarsely, densely, 

 irregularly punctate, coarsely, confluently granulose between punc- 

 tures, with numerous, irregularly placed, broad, rasplike teeth at sides 

 on anterior half, and a transversely arcuate ridge, which is interrupted 

 at middle, near anterior margin, rather densely clothed with long, 

 erect, brownish hairs at sides and along anterior margin. 



Elytra at base subequal in width to pronotum at middle, with a 

 narrow, smooth costa extending along lateral margins from humeri 

 to apical declivity; sides parallel, conjointly broadly rounded at 

 apices; surface glabrous, shining, densely, deeply, coarsely punctate, 

 sometimes more or less rugose on apical declivity. 



Body beneath densely, finely punctate, sparsely clothed with long, 

 semierect hairs on sternum and apex of last abdominal sternite, with 

 very short, recumbent, inconspicuous hairs on abdomen. Posterior 

 tarsi armed on underside with long, silky, brown hairs. 



Female. — Differs from the male in not having the long, silky brown 

 hairs on the underside of the posterior tarsi. 



Length 7.5-16 mm., width 2.5-5.5 mm. 



Type locality. — Europe ; location of type is unknown to the writer. 



Distribution. — This species is found in all of Europe (except Nor- 

 way, Sweden, Scotland, Ireland, and northern Russia), the Medi- 

 terranean Islands, Morocco, Algeria, northern Tunis, Asia Minor, 

 Syria, and Caucasus. Adults of this species were intercepted at 

 Newark, N. J., and New York in licorice roots from Turkey. Adults 

 of capucinus were reared from the oak strips used for binding large 

 quantities of cork stored along the railroad tracks near Nicholson, 

 Miss., during 1943^L4. This material was shipped from northern 

 Africa. One specimen of the black variety, Bostrichus capucinus var. 

 luctuosus Olivier, was also reared from the same material. So far as 

 known, the species has not become established in the United States. 



Hosts. — Lesne (1901) states that in the temperate parts of Europe 

 this species prefers the stumps and large roots of oak, but also lives in 

 a number of other plants. It has been recorded in the literature as 

 living in chestnut, locust, mulberry, myrtle, grape, strawberry tree, 

 English oak (Quercus robur), evergreen oak (Quercus ilex), Quercus 

 toza, Calyctome spinosa, and the jujube tree (Zizyphus lotus). It has 

 also been recorded in pine, but this may be an error.
