Form less clon<?atc, ])rotIiorax more transverse, sides straifjhter and 
less conver»;enl beliind S svhvtiais. 
I'ront 7-striate. 
I’rothorax rather strongly narrowed posteriorly, interstriae of elytra 
feebly or sc.'ircely alnlaceons, a single dorsal pnnetnre 9 obscnnis. 
Protborax less narrowed posteriorly, interstriae of elytra distinctly 
alntaceons, ilorsal punctures nsnally two in number 10 iiitciis. 
Iwont about 12-striate: lateral interstriae and sutural interspace opaque, dorsal 
punctures usually three, rarely two or four 11 si'iiiiol'iicu.'i. 
1. X. acnciis blbst. 
\’ery distinct from all our remaining species and at once recognizable by 
the pale legs and antennae. It represents an entreme among our species in its 
larger bead, stouter antennae, deeply sinuate sides, prominent hind angles aird 
broadly impunctate disk of the protborax, and in the less unecpial elytral inter- 
spaces, thereby apjtroacbing the usual type of striation in the Carabidae. The 
labrum is here distinctly emarginate at ajicx, but scarcely at all so in our other 
species. The dilation of the inale tarsi is at a minimum, being scarcely de- 
tectable, and the squamules of the middle tarsi are few in number. 
Acnciis is a common species in the Xorthern Stales and Canada from Xew 
England to Lake Superior and Illinois, and extends as far south as North 
Carolina. (Blanchard). 
2. X. scmistriatiis Say. 
In its rather strongly narrowed and sinuate sides of the prothorax, and the 
relatively narrow second elytral interspace, this species a])proaches aciicits more 
closely than does any other, and forms a natural transition to those whicli 
follow. It is, as a rule, a little more robust than acucus, and differs from it and 
all other s]x‘cics of the 5-striate group cxce])t syh'aticiis and ncnwralis in its 
more distinctly impressed and more coiu])lete elytral striae, which though fine 
are all (juite evident at apex. In color it is black, moderately bronzed, surface 
()olished throughout, I)asal four joints of antennae, and tibiae in great part, 
pale. Terminal joint of palpi (es])ecially the labial) (juite strongly dilated and 
truncate. 1 have seen several examj)les in which the discal annulate jnmeture 
of the elytra is wanting, a condition not yet observed in any other sjtecies.
