b. Smaller species. 



* Head black ; scutellar stria distinct. 



3-5 — 4 mm. Prothorax pale ; hind angles much rounded ; basal impres- 

 sions with a few coarse punctures ; elytra with a broad, dusky stripe or cloud, 

 divided by the sutural interval ; body dusky beneath 7. partiarius. 



3 — 3-25 mm. Very similar to p a r t i a r i u s, but smaller, with the basal im- 

 pressions less marked, and still more sparsely punctured ; elytra dusky, with 

 the suture and margins pale ; prothorax pale above and beneath ; trunk al- 

 ways and abdomen usually dusky 8. pauper cuius. 



3 — 4 mm. Equal in size io partiarius, but narrower, with the sides of the 

 prothorax not rounded behind, but even feeblj' subsinuate ; the hind angles 

 are, however, rounded, the disc marked with a large, quadrate, blackisli spot ; 

 elytra blackish, with the suture and margin testaceous; scutellar stria longer 

 than in partiarius 9. i n d i s t i n c t u s. 



** Head pale, of the same color as the prothorax; body testaceous or fer- 

 ruginous beneath, not blackish ; scutellar stria short or wanting. 



2-5 — 3 mm. Prothorax with the hind angles much rounded ; basal impres- 

 sions faint, marked with a few large punctures; elytra with the scutellar stria 

 punctiform ; disc sometimes with a faint dusky cloud 10. t e s t a c e u s. 



2-75 mm. Of the same size and form as the preceding, with the scutellar 

 stria distinct though short, not punctiform 11. micros.

Carabus comma Fabr. cannot be referred to this specis, as is erroneously 

 stated in the Melsheimer Catalogue and thence copied into my List, since it is 

 described as having the head black.

*The MS. descriptions and remarks of Dr. Zimmermann upon this and the nextspecies 

 are so important that I have translated them : 



" A. c o m ni a. Abundant iu tlie Northern States ; 2% — .3)^ lines long. 



" .\ltogetlier similar to A. p al 11 pe s in form and color, and usually confounded with 

 it; differs in the marking of tlie elytra, upon eaoh of which there is a black stripe, so that 

 the suture remains yellow; this stripi^ extends from the first to the fifth stria, and is com- 

 monly abbreviated in front, sometimes, however, attaining the base, but never the suture. 

 The dorsal spot of the prothorax is sometimes wanting; the hind angles are somewhat 

 more obtuse, and the scutellar stria of the elytra longer than in the next species. 



"A. pal 1 ipe s. Abundant in the Southern States ; 2 — 3 lines long. 



" Body elongated, not very convex, testaeci ms ; mouth, palpi, base of antennie, feet and 

 anus reddish-yellow; under surface and iiend lilaek ; a large black or brown spot on the 

 middle tit tlie prothorax, and a broad lilaek stripe on the elytra, which extends from the 

 suture to the fourth stria, pointed in front and reaching the scutellum. Head with deep 

 frontal impressions and moderately large eyes ; prothorax narrowed behind; hind mar- 

 gin and shallow basal impressions thicdvly punctured; hind angles rather obtuse than 

 rounded ; elytra wtth deep, smooth striiB, short scutellar stria and a distinct posterior 

 dorsal puncture upon the second stria. 



" Vi'eniaW.s.— It is iiliviously this sjiecies and not the preceding which Fabricius des- 

 cribed from the Hunterian cnlleetion. This is apparent, n )t only ni the words 'Coleoptera 

 nigra limlto pallido,'but also by the descrijition and figure given by (Jlivier under the same 

 name, with the additional remark that the iuseet was found in ("aroliuu. A. /> tllijirsDe}. is' 

 aniitlier species which is found in the Nnrtheru .States, and descrilieii liy Faljrieius under 

 the name Cn: comma in the fcjllowing words: ' Elytr.i grisea, macula lineari nigra versus 

 snturam." The specimen of Caruhns pallipes in the Fabrician cabinet is a Cymiudis varit- 

 gata Dej,, according to Schanm, Stettin Ent.. Zcitung, 1847, 47. 



1868.]
