450 Mr. J. Walton on the genus Otiorhynchus. 



convex and finely punctured; eyes brown and prominent; ros- 

 trum a little longer than tlie head, porrect, incrassated at the 

 apex, angulated, thickly punctulated above, carinated in the 

 middle, and bifui-cate at the apex. Antennse half as long as the 

 body, black, pilose and pubescent. Thorax narrow, a little longer 

 than broad, somewhat constricted at the base, the margin slightly 

 elevated, moderately dilated, and rounded at the sides before the 

 middle, convex, and minutely punctured and wrinkled above, 

 and distinctly granulated at the sides. Elytra anteriorly not 

 broader than the base of the thorax, the sides gradually dilated 

 to the middle, and from thence attenuated to the apex, convex 

 above, distinctly punctate-striate, the interstices transversely 

 rugose, very nearly glabrous, and the ultimate segment of the 

 abdomen delicately striated. Legs rather long, robust, rufo-fer- 

 ruginous or rufo-piceous, pubescent; the femora clavate, with 

 the apex piceous or black; the tarsi also piceous or black. — 

 Male. Length 4^ to 5| lines. 



The female differs by having the thorax with the sides dilated 

 and rounded at the middle ; the elytra broader, dilated at the 

 sides a little before the middle, and narrowed to the apex ; the 

 ultimate segment of the abdomen punctulated. Varieties of the 

 female sometimes occur, although rarely, with the striae on the 

 elytra indistinct, especially on the disc of each elytron : the 

 colour of the elytra and the legs in both sexes varies as in the 

 preceding species. 



There is undoubtedly a very close affinity between this and the 

 preceding insect ; nevertheless I am of opinion it is sufficiently 

 distinct, and that there is by far too great a difference between 

 them to admit of their being united into one species ; this is a 

 shorter insect, and very generally smaller and less pubescent ; 

 but it chiefly differs by having the antennae in both sexes, with 

 all its articulations, distinctly shorter and stouter ; the elytra of 

 the female evidently shorter in proportion to the breadth, and 

 more or less distinctly punctate-striate ; the knee-joints in both 

 species are more or less strongly coloui'cd, but too inconstantly to 

 be of any value as a specific difference. 



I have applied the name ^fuscipes of Oliv.' to this insect on the 

 authority of Schonherr, having sent specimens for his examina- 

 tion. I have no doubt that Ot. Fagi, of which I possess a speci- 

 men from Chevrolat, and with which the description of Schon- 

 herr agrees, is but a female variety of this insect, having a 

 smoother surface, and the elytra indistinctly striated. 



I forwarded many specimens ( c? ? ) as Ot. fuscipes of Oliv. 

 and Schonh. to Germar, who referred them to Ot. tenehricosus 

 as varieties.
