54. Ij. ilicis Knoch. — Oblong, slightly broader behind, brown, more or less 

 opaque, elytra pruinose, surface sparsely clothed with short, recumbent hair, 

 equal in length. Head piceous, with very short erect hair. Clypeus rather 

 deeply emarginate, the border not widely reflexed, surface with the front, very 

 densely and coarsely punctured. Thorax widest at middle, slightly narrowed at 

 base, more obliquely narrowed in front, the margin creiiate and ciliate, surface 

 very densely granulate punctate, usually with a slightly elevated, smooth, median 

 line, the pubescence recumbent and not conspicuous. Elytra densely punctu- 

 late and finely rugulose, the punctures shallow and for the most part indistinct, 

 the discal costte indistinct, the submarginal moderately distinct, the pubescence 

 fine gray and recumbent, the margin usually ciliate. Pygidium shining, coarsely 

 sparsely punctate. Metasternum densely punctured, the hairs long, but not dense. 

 Abdomen moderately coarsely punctured at the sides, but not densely, each 

 puncture with a short hair, the last two segments more coarsely punctured. 

 Claws curved, tooth strong and median. Last joint of maxillary palpi fusiform, 

 obtuse, not impressed. Length .75 —.92 inch : 19 — 23.5 mm. 



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

 domen flattened at middle, the penultimate segment (fig. 85) broadly 

 ti"ansversely impressed with an oblique tuberosity each side. Last 

 segment irregulai'ly concave, distinctly emarginate at apex. Py- 

 gidium regularly convex, broader than long, the punctures not deeply 

 impressed. Inner spur of hind tibiae half the length of the outer, 

 stout, obliquely truncate. 



Female. — Antennal club much shorter than the funiculus. Meta- 

 sternum with shorter and sparser pubescence. Pygidium longer 

 than wide, more convex at apex, punctures more abundant and 

 dee])ly impressed. Posterior tarsi slightly shorter. 



Variations. — All the specimens have the elytra distinctly prui- 

 nose, but to a variable degree, the specimens from the northern re- 

 gions less distinctly. These latter have the discal costse more evident, 

 although they are never well developed at any time. The color 

 varies but little. 



The legs have always a (dearer red color than the under surface 

 and more shining, the femoi'a of the female are always stouter than 

 the male. 



With this species I have united sabtonsa Lee, founded on a single 

 specimen which has lost the cili?e of the elytra rather through acci- 

 dent than for specific reasons. 



After a study of a pretty large series I believe it probable that 

 liurmeister described his Uicis from an immature specimen. Two in 

 my cabinet fit his description very well, and here it may be observed 

 that the less mature the specimens are the greater the tendency of
