444 SI'BPAMILY X. CURCULIONIN^E. 



The late M. Y. Sliugerland (Bull. 78, Cornell Univ. Agr. Exp. 

 Sta., 1894) first mentioned this species as the "seed-stalk weevil" 

 and as damaging fields of seed cabbage on Long Island. The 

 larvae, many in a single stalk, burrow in the pith of the seed- 

 stalk and its main branches, finally causing the plant to wilt and 

 break over just before the seed begins to mature. At the end of 

 June or early July pupation takes place in earthen cells near the 

 base of the stalk a little below the surface. The species was not 

 recognized by Dr. Horn, to whom it was sent for identification, 

 but later (1901) was identified for Sliugerland by Chittenden, the 

 identification being confirmed by Schwarz.* 



686 ( ). CEUTORHYXCHUS MARGINATUS Payk., 1792, 27. 



Short-oval, moderately convex. Black, opaque, densely clothed above 

 with brownish appressed hairs and a few white scales, the latter arranged 

 in a single row in each stria and condensed to form a conspicuous, oblong, 

 sutural white spot immediately behind the scutellum and a few minute 

 clusters near the front margin on either side of thorax; tarsi reddish-brown; 

 beneath densely clothed with white scales. Thorax transverse, deeply con- 

 stricted in front, apical margin elevated; disc without tubercles or median 

 channel and small acute lateral tubercles, coarsely and densely punctured. 

 densely punctured. Elytral striae narrow, intervals wider, flat. Hind fe- 

 mora strongly, the front pair very feebly toothed; claws with a long, al- 

 most bifid tooth. Male with a large, oval, transverse impression on last 

 ventral segment. Length 3 3.2 mm. 



An introduced European species, numerous examples of which 

 have been taken at Ithaca, X. Y., March 12 July 21; also at 

 Framiugham, Mass., and Cincinnati, O., (the scrictins of Dury's 

 list). Found on lettuce and reared from buds of dandelion by 

 Herrick.

 puncture bearing an oval whitish scale; antennae, tibiae and tarsi piceous;

 and thorax, curved, cylindrical, finely punctured and striate in male, 

 smooth on apical half, female. Eyes only partially concealed by the very 

 small ocular lobes. Thorax slightly wider than long, sides strongly round-

 Elytra ovate, convex, one-third wider at base than thorax; striae wide,
