150 DESCRIPTIONS OF NEW SPECIES. 



AIVISOXYA Muls. 



443. A. glaucula. Elongata, antice breviter, postice longius attenn- 

 ata, fusca transversim subtiliter aciculata, et pube subtili sericans, 

 thorace convexo, fere seniicirculari, basi vix bisinuata, baud rnarginata ; 

 elytris a basi sensim angnstatis ; corpore subtus antennis pedibusque 

 fusco-testaceis. Long. -14. 



Pennsylvania ; rare. The genus Anisoxya is easily distin- 

 guished by the spurs of the middle tibiae being larger than those 

 of the hind tibia?, and unequal ; the larger of the two is nearly 

 one-half the length of the first tarsal joint. The antennae are 

 scarcely longer than the head and thorax, with the 3d joint not 

 longer than the 2d, 4th-10th equal in length to the 3d, nearly 

 square, 11th one-half longer, oval. The sculpture is peculiar, 

 consisting of fine impressed lines having a transverse direction 

 and connected together, producing a somewhat squamous appear- 

 ance. 



I perceive no trace of the two posterior oblique impressions 

 mentioned in the description of the European species.

A "genus containing two small species, apparently allied to the 

 European Carida, but differing by the emarginate eyes, and 

 slender front tarsi. The characters as above detailed agree with
