equal to about three-fourths of elytra in length, last three joints larger, very 

 slightly flattened, and forming a loose club. Last joint normal in shape, but 

 rather longer than the preceding. Vittae distinct as in male. Length 2.9 mm.

A full series of this fine species is before me from the cabinet of Dr. 

 LeConte, also two specimens from Mr. Schwarz, all from Texas. The 

 peculiarity in the last joint of the male antennae is, I believe, unique in 

 the genus. 



2. li. bignttatiis (Say). Male. — Dark castaneous, a spot of a circular out- 

 line, and well defined, before the centre of each elytron is of a lighter tint; legs 

 and antennae a little paler. Surface densely punctured. Head triangular, eyes 

 moderate, transverse groove strong. Prothorax narrowed behind ; sides very 

 arcuate, lateral grooves well marked. Elytra nearly twice as long as the head and 

 prothorax together, strongly margined, striate and obtusely rounded. Antennae 

 shorter than elytra, joints sub-equal, first joint longest, second shortest, last three 

 joints slightly broader and flattened. Length 3.0—3.9 mm. 



Female. — Color and punctuation same as in male. Head and prothorax much 

 smaller. Antennae equal to half the length of body; last three joints suddenly 

 larger, forming a loose club. Length 2.6 — 3.0 mm.

This is a common species distributed throughout our territory. 



3. li. rascia.tllS Mels. Male. — Body pale castaneous; elytra somewhat 

 darker; legs and antennae of same color as prothorax. Surface rather lightly 

 punctured and shining. Head sub-triangular, transverse groove well marked. 

 Prothorax slightly narrowed behind, a little broader than head, lateral striae well 

 marked: sides arcuate and slightly sinuous. Elytra equal in length to twice the 

 head and prothorax together; an irregular, somewhat indefinite spotof lighter tint 

 is usually present before the middle of each, which generally attains the exterior 

 edges; sides sub-parallel, slightly arcuate; rather obtusely rounded posteriorly; 

 strongly margined and striate. Antennae slightly longer than head and prothorax 

 together, joints gradually larger toward the tip; last three broadest and flattened. 

 Length 3.1 mm. 



Female. — Colors and punctuation same as in male. Head and prothorax much 

 narrower. Antennae a little longer than head and prothorax together, last three 

 joints suddenly larger. Elytra of proportionally the same length as in male. 

 Length 2.6 mm.

The last two species resemble each other .somewhat, until closely ex- 

 amined ; fasciatus may be recognized at once, however, by the antennae 

 and punctuation ; it is widely distributed. 



4. Ij. L-eContei Grouv. Male. — Testaceous throughout. Surface lightly 

 punctured and shining. Head sub-triangular; eyes moderate. Prothorax equal 

 in width to head across the eyes, narrowed slightly behind; sides moderately ar- 

 cuate ; lateral furrows very well developed. Elytra about one-third as long again 

 as the head and prothorax together ; equal in width to prothorax, entire, strongly
