This very distinct species bears a decided resemblance to some of 

 the varieties of L. analis and D. scapularis, from both it may at once 

 be known by its punctured and not grooved head. The testaceous 

 stripe which divides the black stripes at base is short, one-fourth the 

 length of the elytra and on the fifth interval. The conjoined black 

 stripes at apex have a trilobed termination. The mentum at base is 

 truncate and the head not not constricted behind, and it is therefore 

 placed in Chaudoir's Aplielogenia. Several specimens received since 

 the above description has been in type, have the basal stripe on the 

 fifth interval wanting. 



One specimen communicated by Mr. Philip S. Sprague, of Boston, 

 who obtained it from Texas. 



A. vittata, Fab, (Carabus) Syst. Eleut. i., p. 202; Dej. Spec, i., p. 267; 

 Chaud. Bull. Mosc. 11.71, i., p. 40 ; flavovittata Chev. Col. Mex. Cent, ii , No. 161 

 (fide Chaud.). — Pale yellowish testaceous, antennae black sometimes with the 

 basal joints paler. Elytra with a sutural black stripe occupying the two inner 

 intervals not attaining the apex nor base, a lateral stripe on the fifth, sixth 

 and seventh intervals, sometimes broader at apical end, but not attaining the 

 basal nor apical margins. Body beneath pale yellowish testaceous, legs vari- 

 able, sometimes totally black, usually with the tips of the femora and the en- 

 tire tibiae and tarsi black. Length .24 inch; 6 mm. 

 Occurs from Pennsylvania to Texas. 



A. furcata, Lee. Ann. Lye. iv., p. 193; Chaud. Bull. Mosc. 1871, i., p. 41. — 

 Similar in color to preceding, with the elytra striped in the following manner: 

 a narrow sutural stripe not attaining apex extending forward, becoming gradu- 

 ally broader to the middle of the suture, where it divides and extends forward 

 attaining the base, the two branches thus enclosing a very narrow triangular 

 space ; an outer narrow stripe starting at the base of the seventh interval ex- 

 tending obliquely inward to the fourth striae but not attaining the apical mar- 

 gin of the elytra. Body beneath and legs as in vittata. Length .24 — .30 inch; 

 6 — 7.5 mm. 



Occurs from Canada to Kansas and California. 



The typical form of vittata is that described above and all the speci- 

 mens before me correspond exactly with it. As compared with /ar- 

 eata the head is decidedly smooth, the thorax narrower, the elytra 

 shorter and less deeply striate. In furcata I include those forms with 

 the middle or sutural stripe furcate at its basal end. They are 

 always larger, elytra more elongate and parallel than vittata. The 

 figure which Chaudoir gives has not the sutural stripe of vittata fur- 

 cate, but has the lateral band more dilated at the apical end than is 

 usual in the species.
