FAMILY II. CAEABIM. 



entire, the inner ones faintly impressed at apex, punctures fine. Length. 

 5 mm. 



Lake, Vigo, Putnam; Marion and Posey counties ; scarce. April 

 23-October 4. This, according to Fall, is the form usually known 

 as sibiricus, it having been wrongly placed under that name by Le- 

 conte. 



43 ( -)• Notiophilus novemstriatus Lee, Ann. Lyc. Nat. Hist., IV, 



1848, 450. 



Shorter, more slender. Metallic bronze, shining ; tibiae and four basal 

 joints of antennae pale. Thorax as in semistriatus, the sides less sinuate. 

 Elytral alutaceous at tip, the striae entire, regularly and distinctly punc- 

 tured. The second elytral interspace is wider than in either of our other 

 species and, as a consequence, the lateral striae are more crowded. Length 

 4 mm. 



Southern half of State ; frequent. March 6-October 9. Prob- 

 ably hibernates as imago. This is the semistriatus of Leconte, nec. 

 Say. 



VIII. Nebria Latr., 1802. 



Species of medium size, having the antennae slender, two-thirds 

 or more the length of body, joints cylindrical ; maxillae armed be- 

 neath with bristles; scutellar striae of elytra always very distinct. 

 About 24 species are known from the United States. Of these but 

 one has been taken in Indiana, though two others may possibly oc- 

 cur. These three species are black and have the elytra truncate at 

 base, the humeri distinct, the third interval with four or five large 

 dorsal punctures. For literature see :

 United States" in Trans. Amer. Ent. Soc, III, 1870, 97-104.

KEY TO INDIANA SPECIES OF NEBEIA. 



a. Sides of elytra subparallel. 



J). Sides of thorax oblique, not sinuate near base ; legs black. 



SUTUKALIS. 



hl>. Sides of thorax sinuate near base ; legs brown or piceous, the tibiae 

 paler. sahlbergi. 

 aa. Sides of elytra rounded ; legs pale yellow. 44. pallipes. 



N. suturalis Lee., 10-11.5 mm., and N. sahlbergi Fisch., 10 mm. 

 in length, belong to the boreal fauna and range from New Hamp- 

 shire westward. They are likely to be found with other members 

 of that fauna in the northern third of Indiana.
