of the prolliorax is miu-li more dilate«i, and the punctiform impressions 

 more distinct. [Say has described a s])ecies, taken on Longs Expedition 

 in Missouri, under the same name. It is doulitful whether Kirby's 

 species is identical or not.]

 Locality unknown. 



The sjiecies cf this genus of minute Bmi/h'/yim are so extremely 

 numerous, nearly 200 liaving been discovered in Britain alone, and so 

 tlifficuit to discriminate, that it is not with great confidence that I give 

 this as a nondescript. I ha\e many undescribed species in my cabinet 

 that come \ery near it, Init I cannot find one that altogether agrees 

 with it. 



Body black, glo.ss deadened by short inconspicuous hairs. Head 

 rather spherical, narrower than the prothorax, \ery minutely punctured ; 

 antennae shorter than the prothorax, rather robust, intermediate joints 

 turbinate, last joint ovate, acute : prothorax sub-orbicular with the sides 

 deflexed, very minutely and thickly punctured : dorsal channel nearly 

 obsolete ; a large ])unctiform impression just above the scutellum : elytra 

 longer and rather wider than the thorax, iiiceou.s-black, extreme tips 

 rufous, very minutely ond thickly punctured : legs piceous-black with 

 rufous tarsi, 



126. Tachvporus AcuDucTis, A'/V/n.- Length of body I line. Taken 

 near Cimiberland-hou.se, lat. 54'. 



[91.] Body dark-piceous, naked, smooth, glossy. Antennae and mouth 

 testaceous : prothorax very smooth, wider than the elytra, posterior angles 

 testaceous : elytra longer than the head and prothorax together, piceous 

 with the external apical angle testaceous ; if viewed imder a good mag- 

 nifyer, they appear covered, especially next the suture, with minute 

 branching scratches, as if made by a pin or needle, intermixed with very 

 small punctures ; abdomen very short and conical, scarcely margined, 

 piceous with the segments paler at their tip. 



127. Tachvporus affinis Kirby. — Length of body, i line. Taken 

 with the preceding species. This species is extremely similar to T. 

 acuductus, but the posterior angles of the prothorax are not testaceous ; 

 the elytra are palish-chestnut and thickly covered with very minute 

 punctures, without any scratches. 



128. Philonthus politus Linn. — Length of body, 5 lines. Taken 

 in Nova Scotia by Capt. Hall.
