teeth, striato-punctate above ; the middle and posterior tibiae 

 subcyh'ndrical, punctato-striate, with a sharp tooth externally. 

 Tarsi moderate. 



Length 1-^^ inch. 



This female is probably a true Dorcus. 



Sp. 11. Dorcus? mnrginalis* W. W. S, (PI. IV. fig. 6.) 



Black, with the margins of the elytra obscure pitchy brown. 

 $ Head subquadrate, transverse, slightly contracted behind the 

 eyes, with a slight rounded projection in the centre of the front, 

 the eyes crossed horizontally by a sharp flat ridge ; the upper 

 surface convex, deeply rugoso-punctate. Mandibles short, rather 

 slender, horizontally porrect, slightly incurved, with one strong 

 tooth on the centre of the inner edge, and a blunt tooth on the 

 upper surface, near the base. Antennae rather short, robust. 

 Thorax broader than the head, subquadrate, transverse, the lateral 

 margins slightly curved outwards ; the posterior margin straight, 

 with the angles rounded; upper surface convex, shining, smooth 

 on the disk, deeply punctate on the sides. Scutellum small, sub- 

 triangular. Elytra about as broad as thorax, semiovate, elongate, 

 the shoulders prominent ; regularly convex, shining, smooth on the 

 portion adjoining the suture, but deeply and coarsely punctate 

 along the sides. Underside of the body shining. Legs short, 

 robust, with the fore tibiae flattened, striato-punctate above, and 

 having a row of about 10 smaller regular blunt teeth on the outer 

 edge ; middle and posterior tibiae subcylindrical, striato-punctate, 

 each with an apical tooth, and another sharply-pointed tooth on the 

 outer edge, a little below the middle. Tarsi short, stout. 



Length IJ inch. 



A 2 provisionally placed in the genus Dorcus. 



This $, except in the much larger size and the nature of the 

 teeth on the fore tibiae, comes very close to the $ of Dorcus 

 lateralis, of Dej. Cat., from the island of Java.

Black, shining. 2 Head sub-semicircular, the eyes crossed 

 horizontally, with a sharp ridge, which there causes a prominence, 

 slightly emarginate in front, with a slight protuberance in the 

 emargination ; convex above, deeply and coarsely rugoso-punctate, 

 with a depression just above each eye, and in the centre of the
