NORTH AMERICAN COLEOPTERA. 269 



the short hairs to become erect. The Jimbriata of Burnieister is the 

 fully mature Hick. 



Occurs from New York to Georgia and Illinois. 



55. Li. ciliata Lee — Oblonji, moderately robust, slightly broader behind, 

 siibopaque, surface sparsely clothed with semi-erect grayish hair with some 

 slightly longer, more erect hairs in vittfe on the elytra, not pruinose. Head 

 nearly black, densely and rather roughly punctate, with short erect hair, clypeus 

 moderately deeply emarginate, the border narrowly reflexed. Thorax widest at 

 middle, slightly narrowed behind, more obliquely narrowed in front, the margin 

 ciliate, not distinctly crenate, surface densely granulate-punctate, the median 

 line slightly elevated, the hairs short and erect. Elytra densely punctate, the 

 postscutellar region subgranulate, the discal costse faintly developed, the submar- 

 ginal distinct, but feeble ; surface not pruinose, the pubescence sparse, semi-erect : 

 the slightly longer, more erect hairs placed along the lines of the usual costfe 

 margin ciliate. Pygidium coarsely punctured, .smoother near the apex and often 

 along the middle posteriorly, the female more densely punctured. Metasternum 

 densely punctured, the pubescence moderately dense, but Jiot very long ; sides 

 of abdomen more coarsely but less densely punctured, the last two segments 

 more coarsely. Claws arcuate, the tooth strong, acute and median. Last joint 

 of maxillary palpi slightly fusiform', not impressed. Length .80 — .85 inch; 

 20 — 21.5 mm. 



Male. — Antennal club slightly longer than the funiculus. Ab- 

 domen flattened at middle, the penultimate segment flattened and 

 flnely asperate at middle, on each side a slight oblique tuberosity, 

 the last segment slightly concave, emarginate at apex. Inner spur 

 of hind tibia broad and stout, obliquely truncate at tij), the outer 

 more slender, nearly twice as long. Pygidium regidarly convex, 

 broader than long. 



Female. — Club of antennje much shorter than the funicle. Pu- 

 bescence of metasternum shorter and le.ss abundant. Pygidium 

 nearly as long as wide, more narrowed towards tip, the surface more 

 coarsely and densely i)unctured, especially above, and more gibbous 

 neai' the apex. Hind tarsi slightly shorter. 



Variations. — Nothing noteworthy has been observed. At times 

 in this species as well as in tlicis, the median line of the thorax is 

 not elevated. 



The lines of longer hair on the elytra are not well marked, and 

 are best seen by looking obliquely from the front. In view of the 

 fact that specimens of crenulata occur with and without these erect 

 hairs, it might be considered questionable whether ciliata should be 

 separated from ilicis. Although my series of bt)tli species is quite 

 lar^e, 1 do not feel justified in speaking positively either way, but 

 leave the matter for future determination. 



Occurs in Wisconsin, Illinois, Mis.souri and Georgia.
