notum. ‘The sculpture is rather coarser than in Lustrophus 
bicolor. Prosternum is not prolonged behind coxze. Posterior 
tibize have transverse ridges, as in &. dzcolor. As compared 
with dzcolor this species is smaller, broader for its length, less 
shining, much less attenuate behind, less distinctly striate, 
with finer punctures in striz, and with the fulvous border, 
Antenne as in bicolor. Two specimens, Kentucky, near 
Cincinnati, Ohio, 4.8 mm. and 3.7 mm. long. 
MORDELLISTENA DELICATULA Nl. Sp. 
Elongate, very slender, piceous in color, with front of 
head, mouth parts, front and middle legs and antennz pale 
rufotestaceous. ‘The elytra thickly covered with rather coarse, 
sage green pubescence. Tibia with two ridges, anterior one 
extending across the outer face of the tibia. First tarsal joint 
with three, second with two oblique ridges. Length 3.5 mm. 
Seven specimens, Cincinnati, Ohio. The most slender species 
I have seen. The bright shining sage green pubescence 
fades out to silvery in old specimens. From the description 
I had always thought this was sp/endens Smith. But after 
seeing some of that species collected at Cameron, La., by Prof. 
Hine, and, comparing with the types in national museum, I 
see it is quite different. 
ACROSCHISMUS 
Acroschismus is a generic name proposed by Mr. W. D. 
Pierce for some new species of the family Sty/opide, specimens 
of which I have bred here from parasitized wasps. I have 
taken three distinct species, for which Mr. Pierce proposes the 
names in following list (Art. XI.). Descriptions will be given 
in a monographic paper shortly to be issued by him.

CANISTES SCHUSTERI Csy.
