NKOTIIANKS gen. aov. (vto?, 



Allied to Carabus, and belonging to tin- same tribe, (,'arabini. It differs 

 from it in some marked features of tin- head. Inn better with it than 



with the (Jychrini, in which it was former! v place. 1. The head is unusually 

 broad and short, the width between thr base of tin- not very prominent 

 round eyes being nearly twin- as great as the length from tin- renter of the 

 eyes to the margin of the labnun. while the burial of tin- head in the pro- 

 thorax up to the base of the eves renders the brevity more apparent ; the 

 labrum is entire, its base just in front of the insertion of the antenna- ; man- 

 dibles shorter and stouter than in Carabus and Calosoma, arcuate, untoothed; 

 tip of maxilla- just as stout as (though probably thinner than) the apex of 

 the mandibles. The head does not appear to be constricted behind the eyes 

 though but little of that portion can be seen in the single specimen which 

 preserves this part. Prothorax and elytra as in ( 'arahns, excepting that the 

 latter have no fovete whatever, and the very numerous stria; are straight 

 and the interspaces smooth and unbroken.

This species was lirst described from the less perfect and more obscure 

 specimen of the two now before me. Tin- better pn-M-rvation of the second, 

 with its thorax and other part.-, shows that the >pecies .-honld he placed in 

 the (Jarabini rather than in the Cychrini. The stout and nntoothed mandi- 

 bles leave no doubt on this point. 



The pronotum is broadest somewhat in advance of the middle and taper- 

 with about equal rapiditv toward the front and toward tin- ba-. >o that the 

 base is somewhat narrower than the front, the external angles well rounded : 

 the front mar-in is nearly, the hind margin quite, straight, the former 

 scarcely angulate in the middle, the lateral angles sli-lnl\ produced ante- 

 riorly; there is a faint median carina, more pronounced in the middle, hut 

 otherwise the thorax appears to he tolerably smooth. thouirh laterally the 

 head is longitudinally BUbrugulose. The elvtra ha\e the humeral an^le 

 well rounded off ami the tip angulate; the stria- are clte and crowded to 

 the number of about twentv-live on each elytron, sharp and clean, but
