ON A NEW SPECIES OF NEOLUCANUS FROM NOETHEEN INDIA. 

 BY CHAS. O. WATERIIOUSE. 



Tlie insect which I am about to describe has been for a long time 

 standing in the British Museum Collection as a new species of Odon- 

 tolahls. M. Henri Deyrolle, on his last visit to England, pointed out 

 that it was a JVieolucanus ; of which genus it is apparently an unde- 

 scribed species, allied to iV. cingulatus, differing especially in being 

 more depressed, and scarcely visibly punctured on the thorax and 

 elytra. 



* Neolucanus marginatus, sp. n. 

 9 . Piceo-niger, sat depressus ; capite thoraceque opacis ; elytris 

 siih-nifidis, suhtilissime punctulafis, nigro-piceis, singulis vittd magna 

 suh-marginaU Jlavd ornatis. Gida impunctata. Tihiis anticis tridenfi- 

 culafls ; tihiis post ids extus quadri-sidcatis (sioJcis fortiter pimctatis), 

 intus punctorum seriehus duahus impressis. Abdomine lateribus apiceque 

 punctidatis, medio Icevi. Long. 18 lin., lat. 8i lin. 



Pitchy-black, with the sides of the thorax pitchy. Elytra pitchy- 

 black, each elytron with a broad ochraceous strijJe 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 disc ; 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 longi- 

 tudinally 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 row^s of deep punctures, one of them forming 

 a slight channel at the base ; the space between this row and the chan- 

 nel 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 se- 

 parated from each other ; the space between these two rows is convex 

 and impunctate. The head is sparingly but deeply punctured on the 

 under-side 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. 



Habitat : Northern India. British Museum.
