 Neolucanus marginatus, C. O. Waterhouse, Entom. Month. Mag. vol. ix. (1872) p. 53. 



Female. " Pitchy black, with the sides of the thorax pitchy ; elytra pitchy black, 

 each elytron with a broad ochraceous stripe extending from the shoulder almost to the 

 apex; this stripe is narrow at the shoulder, then somewhat suddenly widens, and 

 remains of an equal breadth for about half of its whole length, and then gradually 

 narrows to the apex, thus leaving the elytra narrowly bordered with black, and with a 

 somewhat triangular patch of the same colour covering the disk ; the suture is pitchy ; 

 the anterior tibiae are furnished on the outer edge with three sharp teeth, and the apex 

 is bifurcate ; the posterior tibiae are longitudinally canaliculate, the channels are four in 

 number on the outer side, deeply and closely punctured ; on the inner or under side 

 there are two longitudinal rows of deep punctures, one of them forming a slight 

 channel at the base ; the space between this row and the channel next to it of the 

 four above mentioned is very convex, and has only four or five punctures ; in the 

 second row the punctures are separated from each other ; the space between these two 

 rows is convex and impunctate ; the head is sparingly but deeply punctured on the 

 underside between the eye and the gula, the gula itself is very shining, with scarcely 

 any visible punctures. The abdomen has the sides and apical segment punctured, the 

 central part smooth, with a few minute punctures visible with a magnifying power.

The following is Mr. Waterhouse's description of the specimen which he presumes to 

 be the male of the above species. The specimens are from the same collection. 



"Black, with the thorax, elytra, sterna, and abdomen pitchy. Very similar to 

 N. lama, but much less convex. The thorax particularly is less arched in the middle, 

 so that there is a much more gradual incline to the lateral margins, and these in con- 

 sequence appear more expanded ; the sides are much more convei'ging in front, the 

 width at the angle before the basal emargination being 18 millim., and at the anterior 

 angles 11 millim. ; in N. lavia the difference is 18 millim. posteriorly and 13 millim. at 

 the anterior angles in an example of the same development ; the anterior margin is 

 much less bowed than in N. lama.

9. Neolucanus pallescens, sp. n. (Plate LXXXV. fig. 2, 6 .) 



Male. Intermediate between N. swinhoii and N. nitidus, similar in size and form, 

 uniform black, with the exception of the elytra ; liead similar to N. swinhoii, eyes
