For the complete synonymy of this species, which is found on both conti- 

 nents, see Schmidt's memoir above quoted, and Redtenbacher's Kiifer, p. 623. 

 The insect is most abundant in the vicinity of our cities, and has probably been 

 introduced by commerce. The synonymy omitted relates to its occurrence on 

 the eastern continent, and therefore has no place in our local fauna. Redten- 

 bacher very properly unites Nacerdes with Anoncodes. 



Asclera Schmidt. 



1. A. dorsalis. Nacerda dorsalis Mels. Proc. Acad. Nat. Sc. 3, 55. 

 * Xanthochroa vittata Say,' Hald. Journ. Acad. Nat. Sc 2nd, 1, 96. Sea shore, 

 South Carolina, Texas : abundant in June. The anterior tibiae have two dis- 

 tinct terminal spurs, so that the species cannot be referred to either of the 

 genera in which it has been previously placed. I can see no reason why it 

 should be separated from Asclera, with many of the species of which it 

 agrees in form. 



2. A. taeniata, elongata, testacea tenuiter pubescens, thorace obovato, 

 latitudine longiore, confertim punctulato, disco utrinque ante medium late im- 

 presso, lateribus piceis, elytris confertim punctulatis, piceis, margine suturaque 

 testaceis, abdomine picescente, antennarum articulo lmo 3io longiore. Long.

Georgia: although resembling the next species in color, this is readily dis- 

 tinguished by the absence of elevated lines on the elytra, and by the basal joint 

 of the antennae being longer than the third joint : the thorax is also of a different 

 form, being regularly obovate, and without a transverse impression. The an- 

 tennae and anterior tibiae are sometimes slightly fuscous.

 dle and Southern States. 



A. signaticollis Hald. is merely a variety of this species in which the brown 

 color has extended over the greater part of the head and legs, and in which the 

 testaceous margin of the elytra has also disappeared.

Two specimens Sta Fe, New Mexico, Mr. Fendler. The thorax is broader, 

 and anteriorly more narrowed behind than in any other of our species. The last 

 (11th) joint of the antennae is nearly one half longer than the 10th, and is dis
