462 Four new species of the Coleopterus Family 



ceque setosis, illis elongatis, plaga magna communi picea 

 praeditis. Capite carina elevatiuscula, a clypeo emarginato 

 egredienti usque ad nucham attingente ; tuberculo ad verti- 

 cem posito : clava antennarum naviformi marginibus denticu- 

 latis, denticulis inferioribus setigeris ; carina centice versus 

 apicem subangulata, versus basin profunde emarginata quasi 

 scissa. Tibiis mediocribus. Long 7/30 poll.

This species is closely allied to Paussus denticulatus^ West- 

 wood, Art. Ent. vol. 2. PL 92, fig. 1, and No. 1, of Capt. Boys' 

 paper in No. 54, J. A. S. new series, in the latter of which the 

 setae of the denticulations of the antennae are omitted in the 

 engraving. It differs from it in the following particulars. The 

 anterior angle of the keel, or fore-foot of the boat-shaped 

 clava of the antennae, is more prominent, and a deep emar- 

 gination runs in under the counter, or basal part of the 

 clava, just behind the insertion of the penultimate joint. 

 The terminal denticulation and the four inferior ones, like 

 the rowlocks of a boat, are alone setigerous, as in P. denticu- 

 latus ; the other five are less prominent and rude. The 

 setae are whitish and not dark. The sculpture of both por- 

 tions of the thorax is similar to that of P. denticulatus , but 

 the proportions differ. In P. denticulatus the breadth of the 

 inferior portion exceeds that of the upper part as well as 

 its own length ; in P. nauceras the angles of the upper portion 

 project beyond the side of the hinder part, and the breadth 

 of the latter is not greater than its own length. The chest- 

 nut edging round the black mark on the elytra is narrower 

 in proportion in the new species, and the elytra are dull, not 

 polished. 



The clypeus in both species is emarginate. In Captain 

 Boys' Nehor species there is merely an excavated tubercle 

 on the vertex ; in P. nauceras the tubercle of the vertex is
