212 SUBFAMILY X. CURCULIONIXJE. 



punctate, scaly behind the antennal insertion; of female one-third longer, 

 much more slender, feebly tapering. Second joint of funicle one-half longer 

 than third. Thorax small, slightly wider than long, widest at middle, 

 narrowed and feebly constricted near apex, sides broadly rounded, disc 

 coarsely and densely punctured. Elytra at base one-half wider than 

 thorax, two-thirds longer than wide; sides straight and parallel in basal 

 half; strife fine, indistinctly punctate; intervals flat, finely rugose, each 

 with a row of very fine, recurved setae. Length 2 2.7 mm. 



Starke and Marion counties, Indiana, scarce; Aug. 3 Oct. 31. 

 Taken at various points in New Jersey,, May July. Chicago, 

 111., Sept. 20. Ranges from Quebec and Massachusetts south to 

 District of Columbia and west to Wisconsin and Kansas. Taken 

 from the glaucous willow, *SV/7/.r discolor Mnhl., in Wisconsin. 



The above is a description of the species recognized by Did/ 

 and in part by Casey as the corniciiJatus of Falmpus, the type of 

 which was from Pennsylvania. It agrees fairly well with the or- 

 iginal description except in the color of the elytra which was 

 given as "nigra, griseo-tomeutosa, fnseo-nebulosa." As with many 

 other North American species described in Schonherr's work, the 

 types of which are now in Stockholm and therefore difficult of 

 access, there has been much difference of opinion as to what 

 form Falmeus had in hand. In the Cambridge collection are two 

 species placed side by side, each bearing the label "". coriiinilatiift 

 Fahr.," in LeConte's writing. One of these is what we now know 

 as scHl/ttiroUix, the other as apianhJcs, both described by Casey. 

 It was probably from the former that LeCoute drew up the de- 

 scription (187G, 173), in which he gave the color as "dark 

 brown, not very densely clothed with narrow, small whitish and 

 yellowish scales/' and the thorax as "much rounded on the sides." 

 Casey (1892, 301) combined LeConte's stjiHtiinilatus with the 

 form as above described, and his description is a composite of 

 the two. Dietz 1 1894, 164) described a form practically as above, 

 and then mentions four varieties. These, as lettered in his col- 

 lection at Cambridge, appear to be a, a small form of his itcbulo- 

 sus; c, the form as above described; 1) and <L the squumulalux of 

 LeConte, of which Dietz's cohinibiaiius is a synonym. Until the 

 type of Fahrteus is studied by some American Coleopterist famil- 

 iar with our species of Siiticroiii/.r, the name corniculatus may as 

 well as any other be ascribed to the form in hand. 



A study of the type of X. Jdnmjiin^ns Dietz in the Horn collec- 

 tion shows it to be a dwarf form (2 mm.) of coni'u-iiloliix with 

 the "conspicuous long hair-like set.e" mentioned by Dietz visible 

 only when viewed in profile, and then scarcely if any more ob-
