30 DESCRIPTIONS OE NEW SPECIES. 



1-3 piceo-testaceis, profunde constrictis, ultiruis nigricantibus parce sub- 

 tiliter punctulatis, antennis pedibusque piceo-testaceis. Long. "12. 



Middle and Western States ; common. Resembles in form 

 T. cavicollis, but is readily distinguished by the differences in co- 

 lor and sculpture. 



ATEMELES Stephens. 



98. A. cava. Ferrugineus, tenuiter pubescens, antennis articulo 3io 

 praecedente duplo longiore, thorace vix conspicue punctulato, lateribus 

 late reflexis, angulis posticis acutis oblique productis, elytris hand dense 

 subtiliter punctulatis, abdomine supra laevigato. Long. ^O-^. 



Massachusetts, Pennsylvania, Illinois ; rare. I have never 

 found this species, and do not know with what species of ant 

 it lives. 



HYPOCYPTIXS Mann. 



99. H. ziegleri. Brevis, niger, nitidus, parce pubescens, thorace an- 

 gulis posticis rotundatis, margine tenuissimo vix diaphano, pedibus an- 

 tennisque obscure testaceis, his sensim clavatis. Long. "03. 



York, Pennsylvania ; Rev. D. Zeigler. Remarkable for the 

 body being almost broader than its length ; each elytron is one 

 half broader than long. The antennae are gradually, and not 

 strongly clavate.

 nitidus, subtiliter pubescens, thorace angulis posticis rectis, elytris sub- 

 tiliter punctulatis, margine latiore concavo ; antennis abrupte fortiter 

 clavatis. Long. *02.

 joints 3-7 are very gradually thickened. 



101. II ? depressilS. Ovalis, latitudine sesqui longiore, supra planus, 

 fusco-testaceus, laevigatus, setis erectis thoracis parcius, elytrorum ab- 

 dominisque lateribus sat dense pilosellus, thorace angulis posticis ro-

Louisiana ; Dr. Schaum. The antennae are broken off, but the 

 tarsi are 4-jointed, and I am, therefore, inclined to refer this curious
