Paratypes deposited in the collections of the U.S.N.M., 
Cornell U., U. of Oklahoma and F. Werner. 
Males with midventral spots on the abdominal sternites 
rnn to couplet 37 in the key but can be separated by the 
absence of scutellar and humeral spots on the elytra. The 
rest key to solani ( pestifera ) and can be separated by the 
short, heavy antennae-. 
Epicauta senilis sp. n. 
The combination of shaggy grey pubescence and pair of 
denuded callosities on the pronotum distinguish this 
species from all others in our fauna. Champion’s candi- 
data from Mexico has similar characters but has the outer 
posterior tibial spurs spoonshaped. 
Length : 9 mm. Head broadly triangular, quite densely 
and moderately deeply punctured, with the intervals quite 
densely punctulate. Median impressed line distinct down 
to the level of the eyes, bordered by a narrow denuded 
area. Antennal calluses small, low. Eyes large, narrow, 
excavated next to the antennae. Antennae slender, twice 
as long as an anterior tibia. First segment slender, 
reaching three-fourths across the eye ; second half as long 
as first ; third just shorter than the first. The basal three 
segments with some short cinereous pubescence behind. 
Fourth and following segments two-thirds as long as 
third, gradually decreasing in thickness. Pronotum 
quadrate, conspicuously bulging on the disc. Median 
impressed line distinct, supplemented by a narrow de- 
nuded area. Basal impressed line distinct. With a pair 
of smooth, denuded callosities just before the middle, as 
in callosa. Surface similar to that of head. The pubes- 
cence on the pronotum is directed irregularly, giving a 
ragged appearance. Elytra black next to the scutellum 
and across the base where normally covered by the base 
of the pronotum. Anterior legs of male not modified. 
Anterior tibial spurs of both sexes rather stout, spiniform,
