closely punctured throughout, a little more coarsely so laterally, 

 without trace of series ; abdomen somewhat shining, finely, not 

 very closely punctate medially. Length 9,0-9.8 mm. ; width 

 4.2-4.6 mm. Texas. [= Epitragus ovalis Csy.]... ovale Csy. 



Form nearly as in ovale but more elongate, very strongly convex, dark 

 piceous, moderately shining, the elytra duller, the pubescence 

 cinereous, short but rather abundant and distinct ; head somewhat 

 coarsely, densely punctate, with the merest trace of fine orbital 

 carinas, the epistomal lobe large, rather acutely angulato-ogival ; 

 prothorax not quite a third wider than long, the apex three-fourths 

 as wide as the base, the sides subevenly and feebly arcuate, becom- 

 ing more converging and subsinuate anteriorly, the angles much 

 deflexed, acute, not blunt and moderately prominent, not everted, 

 the basal angles acute and very slightly everted ; surface evenly 

 and strongly convex, not very finely, perforately and not very 

 closely punctate, with a narrow smooth line medially, gradually 

 not very coarsely but very densely and coalescently so laterally ; 

 elytra three-fifths longer than wide, barely three times as long as 

 the prothorax and two-fifths wider, subinflated behind the middle, 

 thence gradually acutely ogival to the tip, the sides less arcuate 

 basally, the humeri obtusely subangular and very slightly exposed 

 at base, the callus narrow and very feeble, almost obsolete ; sur- 

 face with very feebly impressed lines suturally, strongly, not very 

 finely and moderately closely punctate, more coarsely, rather 

 densely and asperulately so laterally ; abdomen shining, minutely, 

 rather closely punctulate medially. Length 9.5 mm. ; width 4.2 

 mm. Kansas (Wallace Co.) obscurum n. sp. 



Form somewhat as in the female of Bothrotes catialiculatus Say, but SttL^S^^'iY' 

 with the prothorax more convex, plumbeo-aeneous, almost opaque, )<f oV ^''tT 

 clothed with short cinereous pubescence ; head densely punctate ; 

 prothorax almost one-half wider than long, narrowed anteriorly, 

 the sides rounded, the apical angles subacute and not at all pro- 

 longed, the surface finely and densely punctate ; elytra densely 

 punctulate and rugose, somewhat obsoletely striate. Length 10. o 

 mm. Kansas. [:= ^//V;'ao'?^5//z^;;/<5^z^j Lec.]...plumbeum Lee. 



15 — Body rather stout, elongate, fusiform, convex, polished, dark 

 piceous or blackish with very strong ieneous lustre, the tibiae, tarsi 

 and antennae rufescent ; pubescence rather long, subdecumbent, 

 nearly white, moderately close ; head coarsely, sparsely punctured, 

 more closely laterally and anteriorly, the epistoma broadly, angu- 

 larly lobed, the lateral lobes very small, rounded, the labrum 

 impressed along the middle and clothed with long silkv hairs ; 

 supra-orbital carina? completely obsolete ; prothorax one-half wider 

 than long, strongly narrowed, the apex about three-fifths as wide 

 as the base, with the angles right, but little produced and evidently 

 rounded, the sides evenly an(l moderately arcuate throughout, the 

 basal angles right, not prominent but not rounded, the surface not 

 coarsely but strongly, sparsely punctate, but little more coarsely
