AMERICAN COLEOPTERA. 205 



2. L.. serricorne Fab. — Elongate-oval, moderately convex, rufotestaceous 

 or brownish red, pubescence moderate, subreeumbent. Head broad, eyes small, 

 not prominent; antennas rather narrow, first joint large, second and third 

 smaller, the latter distinctly triangular; fourth to tenth about as wide as long, 

 the intermediate ones slightly widest; eleventh oval, slightly longer than the 

 tenth. Punctuation of entire upper surface fine, uniform, not dense, the punc- 

 tures separated by from one to two times their own diameters. Anterior tibise 

 distinctly widened and compressed toward the apex, the outer apical angle 

 obtuse. Length 2.2-3 mm. 



Widely dispersed over the globe by commerce, occurring more 

 commonly in and about commercial centers. It depredates like 

 Sitodrepa panicea on a variety of dried vegetable products, but is 

 especially injurious to tobacco. 



The following localities are represented in the material studied : 

 Massachusetts, New York, Pennsylvania, Michigan, Florida, Texas, 

 Louisiana, California. 



3. Ii. bicoior n. sp. — Differs from serricorne very little in sculpture and ves- 

 titure. but is a little broader, uniformly smaller, and differently colored, the head, 

 prothorax and appendages being always rufous, the rest of the body piceous. 

 Length 1.5 mm. 



Peekskill, New York (Sherman) ; Pennington Gap, Virginia 

 (Hubbard and Schwarz). 



Three examples only ; one from the former locality in my own 

 collection and two from the latter in the National Museum collection. 



4. Ii. semirufum n. sp. — Rather more elongate than serricorne and much 

 smaller. The elytra are piceous-brown, the head, prothorax, under surface and 

 appendages rufous. Sculpture and vestiture as in serricorne, except that the pu- 

 bescence is a little shorter and more truly recumbent and the punctuation a little 

 sparser. Length 1.5 mm. 



Pennsylvania, District of Columbia, Maryland, New Jersey (A.n- 

 glesea) ; Ohio (Cincinnati). 



Nearly similar to bieolor in coloration, but narrower and with a 

 fine raised metasternal line extending from the side margin obliquely 

 inward and backward, becoming evanscent toward the middle of the 

 metasternum, where it bends slightly forward. 



5. Ij. hemiptychoides n. sp. — Very closely allied to semirufum, from 

 which it differs in no notable way, except color and somewhat larger size. The 

 form seems to be just perceptible narrowed posteriorly, parallel in semirufum, the 

 pubescence more prostrate and slightly less sparse, the punctuation of the head 

 a little finer and sparser, while that of the elytra is perhaps a little closer than in 

 semirufum. The fascies is strikingly like some of the smaller species of Catorama 

 (Hemiptychus). Length 1.3-1.9 mm. 



New Jersey (Anglesea); Maryland (Bladensburg).
