 (Ulke) Plate VI, Fig. 10. 



This species appears to be very di.stinct ; the description and figure 

 have been taken from Dr. LeConte's type-speciuic n, which is a male. 



The female differs materially Irom the male. In the former the head 

 has no indication of the deep excavation at the sides, and the first joint 

 of the antennae is only equal in length to the next two together. The 

 entire antenna is also much shorter than in the male. Ihe female was 

 described by Dr. LeCitnte as L. gcminatus. Plate VI, Fig. 13. 



13. Li. llorni n. sp. — Body depressed, moderately elongated; entire surface 

 covered thickly with short, cinereous setae, whic^h have no definite order on the 

 head and protliorax, but which are arranged in closely approximate rows on the 

 elytra; the head and prothorax are, in addition, punctured thickly, and rather 

 coarsely. Color testaceous, integuments thick and oj)aque. Head sub-triangular; 

 eyes moderate, coarsely granulated, very slightly in advance of posterior angles; 

 sides bordered and sinuous; transverse groove not visible, no median line. Pro- 

 thorax sub-quadrate, wider than head, slightly narrowed behind, dorsal surface 

 nearly plane ; surfaces between lateral striae and sides very concave: sides rather 

 acutely and deeply undulated ; lateral striae well developed. Scutellum sub-tri- 

 angular and transverse. Elytra much wider than prothorax : about twice as long as 

 the head and prothorax together; entire and evenly rounded behind, faintly costate 

 and strongly bordered; dorsal surface flat; surfaces between lateral border and 

 sides slightlfl concave ; inflexed sides broad and well deveb'ped ; sides parallel and 

 arcuate; abdominal segments sub-equal; antennae a little longer than the head 

 and prothorax together; last three joints larger; last joint largest, oblong, flat- 

 tened, and strongly carinate ; all densely pubescent. The female does not difl^er 

 perceptibly, excepting that the last three joints of the antennae are less flattened. 

 Length 1.8 mm.

I take pleasure in dedicating this very distinct species to a friend 

 whose instructions have been of the greatest value to me, and to whom 

 I feel greatly indebted. 



14. Ij. rotiiiidioollis n. sp.— Form elongated, moderately depressed ; sur- 

 face clothed with pubescence, which on the elytra is arranged in rows. Head and 

 prothorax punctured as \n punctaius. Color dark testaceous; legs and antennae 

 same. Head elongated ; eyes small, their own length in advance of posterior an- 

 gles. Prothorax slightly longer and broader than head, length equal to breadth, 

 rouniled behind; latei'al striae not prominent; sides very faintly and obscurely 

 undulated; anterior angles rounded ; posterior angles almost obsolete. Scutellum 

 small. Elytra one-third as long again as head and prothorax together ; as broad 

 as the latter ; entire and evenly rounded behind ; sides parallel, and nearly straight. 

 Antennae rather shorter than head and prothorax together; first joint small, first 

 eight moniliform, eighth joint smallest, last three ratiier abruptly enlarged, sub- 

 equal and not flattened ; terminal process of last joint well developed. 



Length 1.9 mm.
