468 Goleopterological Notices, VII. 



Head small, fully as long as wide, the eyes large, prominent, at the middle of 

 the sides, the occiput rounded at hase, becoming less broadly rpunded behind 

 the eyes ; antennal prominences very feeble or subobsolete, the cavities rather 

 widely separated on the declivous front ; clypeus normal, rectilinearly trun- 

 cate ; labrum large ; maxillary palpi normal. Antennie as long as the head and 

 prothorax, rather slender, the club narrow but very abrupt and parallel ; 

 second joint nearly as long as the first but much narrower, feebly obconic, as- 

 long as the next two and much thicker, scarcely 3^ longer than wide ; three to 

 six cylindric and subequal in width, the fifth rather more swollen ; third fully, 

 the fourth and sixth not quite, as long as wide ; fifth very little longer than 

 wide ; seventh only very slightly wider than the sixth, parallel, fully as long 

 as wide or rather longer; eighth fully }4 wider, as long as wide, feebly obconic;. 

 ninth and tenth just visibly wider, }4: and nearly 3^ wider than long ; eleventh 

 not thicker, obliquely pointed, not more than 3^ longer than the tenth. 

 Prothorax about as long as wide, % wider than the head, the sides feebly 

 arcuate and convergent nearly throughout anteriorly, but parallel near the 

 base ; surface smooth, with two feeble median fovese near the base which are 

 connected by a feeble impression ; disk without lateral fovese or basal modifica 

 tion. Elytra short, oval, 34 longer than wide, scarcely twice as long as the 

 prothorax and % wider, oval, widest only slightly before the middle, the sides- 

 strongly, evenly arcuate throughout the length ; apex acutely ogival ; humeral 

 plica and impression obsolete ; basal fovese small and feeble ; subsutural im- 

 pressions obsolescent, the suture not beaded or modified toward base. Legs 

 slender, the femora subequally and only moderately clavate. Length 0.8 mm. ;: 

 width 0.36 mm. 



Iowa (Iowa City). Mr Wickham. 



The abdomen is generally retired considerably within the 

 elytra at the sides, the flanks of the elj^tra being very deep. The 

 posterior tarsi are of normal structure, filiform, with the first 

 three joints equal, the fourth a little shorter, No sexual marks 

 are discoverable in the two specimens before me. 



2. S. CTanescens n. sp. — Eather stout, only feebly ventricose, polished' 

 and impunctate, black, the elytra dark brownish-rufous, with the suture nar- 

 rowly blackish ; legs and antennae testaceous, the club of the latter dusky ;: 

 head and elytra glabrous, with a few isolated setse as in the preceding species;, 

 prothorax densely bristling with unusually coarse hairs and slender spicules 

 on the flanks and apical parts of the disk, the disk broadly and completely 

 glabrous toward base. Head very small, barely as long as wide, the eyes very 

 large, convex, prominent, coarsely faceted and situated at the middle of the 

 length ; occiput broadly rounded behind them, the tempora short and oblique-,, 

 vertex flattened ; antennal prominences small and feeble ; clypeus simple. 

 Antennse slender, as long as the head and prothorax, the club rather narrow 

 and parallel but very abrupt ; second joint slightly shorter and thinner than 

 the first, oval, barely % longer than wide, as long as the next two and dis- 

 tinctly thicker ; three to seven equal in width, cylindric; third and fourth.
