the season's brood emerges in late summer. L. recta*. Lee., (re- 

 corded from Lake Harney. Fla., by Sclnvarz) is said by Casey to 

 be based on a small female of concurus. The latter is easily 

 known from all other Lixi by its large size, rather slender body 

 and the very deep common dorsal cavity of thorax and elytra. 



506 (8497). Lixus MUCIDUS Lee., 1876, 158. 



Elongate, cylindrical, much more robust than concavus. Black, densely 

 and very evenly clothed with short, fine, ash-gray pubescence. Beak stout, 

 strongly curved, densely and finely punctate, finely carinate behind the 

 antennae. Thorax as in concavus. a little shorter, not constricted at tip; 

 disc with fewer coarse punctures and with the median impression less 

 elongate. Elytra slightly wider than thorax, the basal impression much 

 more shallow than in concavus, the tips separately subacute. Length 

 1215 mm. 



Throughout Indiana, but much less frequent than 

 Feb. 21 Oct. 10. Hibernating in numbers beneath logs on sandy 

 hillsides on the dates given. Taken from stems of grasses along 

 borders of marshes in summer. Bred from sour dock by (\ M. 

 Weed and recorded by him as also attacking rhubarb, and by 

 Webster as puncturing and eating out the heart of the stems of 

 young corn. Recorded only from Ohio. Indiana and Illinois. Our 

 most robust species of Li.rux. but surpassed in length by L. fini- 

 briolatus. 



507 (8491). Lrxrs SYLVIUS Boh., Schn.. 1843, II, 430. 



Elongate, slender. Black, rather sparsely and unevenly clothed with 

 rather long, fine, grayish hairs, somewhat condensed on sides and middle of 

 thorax and elytra; antennae reddish-brown. Beak as described in key. 

 Thorax conical, as wide at base as long, sides parallel on basal two-thirds, 

 thence rounded to the constricted apex; disc very coarsely and rather 

 sparsely punctate, the intervals between the punctures minutely punct- 

 ulate, the median impression on basal third distinct but rather shallow. 

 Elytra with sides parallel for four-fifths their length, thence converging 

 and compressed to the separately subacute tips; disc with rows of large 

 punctures, separated by almost their own diameters, the sub-basal impres- 

 sion broad, rather shallow. Under surface of head, pro- and mesosterna 

 and sides of abdomen densely clothed with long yellowish hairs. Length 

 7 9.3 mm. 



Southern half of India mi, scarce; May 23 July 22. Taken 

 by sweeping roadside herbage. Kanges from Pennsylvania and 

 District of Columbia west and south to Kentucky and Florida.
