ClCINDELHXE AND CARABID/E 129 



moderately impressed, the scutellar very short, barely extending 

 beyond the fovea, the intervals feebly convex; subapical marginal 

 sinus almost obsolete; legs rather short, the tarsi very slender; pro- 

 sternal intercoxal process not margined. Length (cf ) 7- 2 ~7-7 mm.; 

 width 2.55-2.65 mm. California (Humboldt Co. Arcata). Three 

 examples ovicollis Schf . 



The only one of the above species that can be compared with 

 longicollis Lee., is fuchsi, and on direct comparison of the above 

 described example of the latter, as identified from description, 

 with the type of longicollis many years ago, I made this note: 

 "Somewhat resembles longicollis but more robust and with a 

 much slighter sinuation near the basal angles." In his original 

 description of longicollis, LeConte states that it is piceous-black, 

 elongate, subcylindric, with the prothorax rather convex, appar- 

 ently somewhat longer than wide and with the sides rounded, 

 posteriorly narrowed, striate at each side at base, the sides 

 briefly sinuate before the small and prominent basal angles ; elytra 

 striate, with the intervals almost flat and the striae moderately 

 deep, impunctate, elongate, not wider than the prothorax, the 

 scutellar stria very short; prosternal process not margined. Length 

 8.2 mm. Oregon. From the original description of sphodrinns, that 

 species would appear to be allied as much to this group as to adoxus, 

 but the size is somewhat larger and the geographic habitat widely 

 different. Arizonicus Schf. may be attached provisionally to this 

 group. 



Group VII adoxus Say. 



The reasons for adopting this group rest almost as much upon 

 habitat as habitus ; it is the only group of the first division having 

 no dorsal elytral fovea that occurs in the Atlantic regions of the 

 continent, excepting a group possibly necessitated by sphodrinus, 

 as implied above, and includes such forms as adoxus, zephyrus, 

 grandiceps and rostratus, of strongly convex, somewhat ventricose 

 form, highly polished, deep black integuments throughout and 

 strongly convex strial intervals, these characters imparting a 

 facies quite different from anything occurring in the Pacific regions. 

 Omitting for the present rostratus and grandiceps, which differ from 

 adoxus and allies in the very large head, the four species before me 

 may be known as follows:
