TENEBRIONID.E. — FEDINUS. 19 



Sp. 2. Marshami. Supra niger subnitidus, infra nigro-piceus, antennis pedi- 

 busque rufo-piceis, thorace postice hisinuato. (Long. corp. 2 lin.) 



N. G. Marshami. Steph. Catal. 243. No. 2430. 



Black, somewhat opaque, very convex : beneath pitchy-h\ack : head and thorax 

 very obsoletely and sparingly punctulate : clypeus anteriorly castaneous, 

 and emarginate : elytra rather faintly striate, the striae subpunctate, the 

 interstices smooth : thorax ample^ with the hinder margins deeply notched 

 on each side near the posterior angles, which are acute : legs pitchy-red ; 

 antenncE the same, but of a paler hue. 



Of this odd insect, which evidently belongs to an uncharacterized 

 genus, I have as yet seen only a single imperfect example, which I 

 obtained from the Marshamian Collection, in which it was placed as 

 an Opatrum, with which genus it is decidedly but little allied.* 



Genus CCCCXXXV.— Pedinus, Latreille. 



Antenna fiYiiorm, 11-jointed, basal joint robust, second small, third slightly 

 longer than the fourth, which is nearly equal to the fifth, sixth and seventh 

 obconic, three following turbinate-subglobose, longer than broad ; terminal 

 orbicular. Falpi maxillary short, with the apical joint simple : labrum 

 narrow, emarginate, placed in a circular notch in the anterior edge of the 

 clypeus : head subquadrate, with the angles rounded : thorax ample, trans- 

 verse, emarginate in front, with the anterior angles acute ; the lateral mar- 

 gins dilated and rounded, the hinder angles not abruptly narrowed : body 

 short, ovate ; elytra rather narrower than the thorax, united : femora stout, 

 posterior with a groove within ; anterior tibics broad, triangular, notched at 

 the apex, intermediate also broad, posterior longer and more slender; tarsi 

 rather short, heteromerous, anterior dilated in the male. 



The true genus Pedinus may be recognised by having the clypeus 

 cut out in a semicircle, in which the labrum is inserted, added to the 

 structure of the terminal joints of the antennas, the form of the 

 thorax, and of the posterior femora.
