Mr. Waterhouse's collection also contaiDS single specimens of 

 the three following species of the genus ScarapMtes : — 



1. — SCARAPHITES WaTERHOUSII. 



Niger nitidus, capite vitrinque canaliculato, thorace sublunulato 

 postice lobato, abdomine latiore cordato, elytris margine 

 antico subpunctato humeris elevatis lateribus seriatim punc- 

 tatis, tibiis anticis dentibus duobus magais parvisque quin- 

 que extus armatis. 



Long. 23 lin., lat. 10 liu. 



This gigantic species is of an uniform shining black. The 

 mandibles are long, strong, and subacute, transversely sfcriolated 

 above and strongly bidentate near the base. The head is 

 broad, with the facial grooves parallel for the first half of 

 their course, and then turning at right angles towards the ante- 

 rior angles of the head. On each side of the head near the 

 clypeus there is a large setigerous puncture, and there are two 

 somewhat distant punctures of the same kind above each eye. 

 The thorax is much broader than long, slightly sinuated in front 

 and gradually rounded away towards the base ; the medial line, 

 except towards the anterior margin, is distinctly marked, and 

 near tlie base, which is slightly emarginate on each side, is crossed 

 by a transverse impressed line. The elytra are broader than the 

 thorax, and taken together are heart-shaped ; along their anterior 

 margin and refiexed lateral margins there is a row of small 

 deeply impressed punctares, while the humeral angles are promi- 

 nent and refiexed. The fore tibite have two lar-ge teeth on the 

 outer side near the apex, and five small ones above them : the 

 middle tibige have a short subacute tooth near their apex. 



I have named this species after its discoverer, Mr. Water- 

 house. It is the finest Scaritideous insect I have ever seen. It 

 approaches more nearly to the species described in my former 

 Paper as iS. obesus, than to any of the others. 



2. — SCARAl^HlTES CRENATICOLLIS. 



Niger nitidus, capite antice medio foveolato corrugato, thoracis 

 lateribus siibcrenatis, elytris convexis postice ampliatis ob-
