 rather closely, not coarsely punctate. Antennal joints either 9 or 10 in 

 number. Thorax short, sides strongly curved in front of middle, nearly 

 straight behind, surface sparsely and rather coarsely punctate. Elytra 

 more coarsely and closely punctate than thorax, the costal almost obsolete. 

 Metasternum sparsely punctured, the hairs short and sparse. Male with 

 antennal club as long as stem ; abdomen slightly flattened, fifth segment 

 sloping downward, last segment feebly concave. Length 10.5-13 mm. (Plate

 shining. Clypeus very feebly emar- 

 ginate, more deeply in female, both 

 it and the front rather Sparsely and 

 coarsely punctured. Thorax rather 

 short and convex, margin slightly 

 crenate, ciliate with long hairs;

 ical half. Metasternum densely Fig. 37i 

 punctured, the hair long and close. 

 Male with antennal club a little 

 shorter than stem ; abdomen broadly impressed, fifth segment feebly eon-

 hind tibiae somewhat S-shaped. Length 12-16 mm. (Fig. 374 and PI. I.

Common in the southern half of State; much less so in the

 April 12 were taken beneath cover and had just emerged as imagoes. 

 Others were taken at light on April 18th and 19th. Readily known 

 by the pale color, long cilia? of thorax and peculiar inner hind tibial 

 spur of male. L. futilis Lee. of the Henshaw Catalogue, is the male 

 of gibbosa and L. serricornis Lee. the female.
