of undescribed Lucanidcc. 51 



Thorax transverse, subquadrate, rather broader than the head, 

 the anterior angles prominent, tlie posterior somewhat rounded, 

 and having a broad shallow tooth on the lateral margins, near the 

 middle ; upper surface very finely granulated, slightly and regu- 

 larly convex. Scutellum rather small, cordato-triangular. Elytra 

 semiovate, rather narrower than the thorax, the shoulders pro- 

 minent, nearly straight at the base, the margins slightly reflexed, 

 the surface regularly but slightly convex, somewhat shining, 

 nearly smooth. Legs moderate — the anterior tibiae with 10 to 12 

 small, blunt, irregular teeth on the outer edge, the middle pair 

 with one small tooth in the middle of the outer edge — the pos- 

 terior pair edentate. Tarsi stout. 



Length 1 J^ inch. Mandibles -^^ inch. 



A nearly allied species to the foregoing, but differing in the 

 shape of the head and mandibles in the $ . 



Sp. 8. Dorcus sir'ialo-punctatus, W. W. S. (Plate IV. fig. 5.) 

 Black, somewhat shining. $ Head subquadrate, transverse, 

 the sides curving slightly outwards, caused by an horizontal 

 ridge crossing the eyes ; somewhat emarginate in front, with 

 a broad, slightly projecting protuberance in the eraargination, 

 having a notch in the centre ; upper surface deeply and coarsely 

 punctate, the vertex with an obscure shallow depression. Man- 

 dibles shorter than the head, incurved, rather slender, with one 

 blunt tooth projecting upwards on the upper side, near the base. 

 Antennae rather long and stout. Thorax rather broader than the 

 head, subquadrate, transverse, the fore angles produced, the sides 

 slightly curving outwards, and the posterior angles rounded — 

 regularly convex, smooth on the disk, punctate towards the sides. 

 Scutellum small, semiovate, pointed, deeply punctate. Elytra of 

 the same width as the thorax, semiovate, elongate, with 13 nearly 

 equi-distant, deeply punctate, longitudinal striae, the striae some- 

 what closer as they approach the side, and the punctures there 

 nearly confluent. Legs moderate; fore tibias somewhat flattened, 

 striato-punctate, with 7 or 8 short blunt teeth on the outer margin ; 

 middle and posterior tibiae sub-cylindrical, each with one small 

 apical tooth, and the former with one small tooth placed centrally 

 on the outer margin. Femora, on the underside, pitchy brown. 

 Tarsi moderate. Underside of body deeply punctate. 

 Length 1 J^ inch.
