Tlicre has recently come to lund from Mr. \V. S. llUlchlcy, of 

 Indianapolis, a small Silpliide, which he recognized as new and which he 

 desires that I should describe in order that it may he included in its 

 proper place in his rorthromin^ tlcscripiive catalogue of the ("oleoptera of 

 Indiana. The insect has much the appearance of an .tniiotoina, and was 

 so taken to he by both Mr. Illatchley and myself until more closely 

 examined. It proves to be rather closely related to l.ioihi. but the 

 diflerence in form, general facies, and certain structural charat lers, seem to 

 require that it be made the type of a new genus, which is briefly charac- 

 terized below. Opportunity is taken to describe at this lime several new 

 species of Aniiotoma in my own collection. 



STtiiiui.iobtb, new genus. 

 I'orm oblongelliplical, subdeprcssed ; elytra with nine regular 

 punctured slriie, the outer one distant from the margin. I^brum arcuate 

 in front, with a small, shallow median emargination. Clypeus with narrow 

 nunibranous border, the frontal suture completely lacking, the lateral 

 frontal impressions feebly indicated, rrosternum as long belore the cox;e 

 as the thi«;kncss of the latter from front to back ; mesosternum strongly 

 oblique ; other characters nearly as in Liodfs. 



Stetholioilii liiticolH\, n. sp. -Oblong-elliptical, subdepresscd, rufo- 

 testaceous, shining. Antenme reaching the hind angles of the protliorax : 

 third joint as long as the three following, fourth slightly longer than wide, 

 si.\lh a little transverse, seventh larger, eighth similar to the sixth, but a 

 little shorter, ninth to eleventh much larger, the eleventh longer than wide, 

 and nearly as long as the two preceding together. Kyes small, feebly 

 convex. Head half as wide as the prolhorax. sparsely, evenly punctulate. 

 Protliorax about twice as wide as long, a little wider than the elytra, sides 

 broadly arcuate and gradually narroweil from the base ; base angles 

 subr«'ctangular with rounded vortices ; surface very minutely aliitaceous 

 and sparsely pumtulale. I*'.lytra more than twice as long as the prothorax. 

 nearly one-fourth longer than wide. \vii!i nine slriii* of punctures, the 

 sutural stria impressed in apical half; strial punctures separated by their 

 own diameters or a little less ; intervals nearly flat and sparsely, irrcgu 

 larly punctulate, the sutural interval not narrower. .Mcta-slernum and 

 alxlomen aUitaccous, the former distinctly punctate, except posteriorly, 

 the latter more sparsely punciatc. Length, .'.7 mm : width. \.U mm.
