Mr. F. P. Pascoe on new Species o/" Lamiidas. 209 



between the eyes not extending to the clypeus ; eyes larger 

 than in T. Wallichu', protliorax rather narrow, not turgid, 

 a stout, strong angular spine on each side ; scutellum equi- 

 laterally triangular ; elytra scarcely punctured excej^t at the 

 sides, their apices broadly emarginate, with five or six jet- 

 black bands, the first at the base ; body beneath black ; legs 

 with a purplish tinge ; mesosternum with a large prominent 

 mainmillary process ; antennee with the third, fourth, and fifth 

 joints plumose, the remainder dull white. Length 12 lines. 



A comparatively short, nearly black species, remarkable 

 for its strongly produced mesosternum. The other two species 

 of this genus are T. Wallichii, Hope (Royle's ' Himalaya,' 

 pi. 9. figs. 5 and 6), and T. tn'cuicta, Lap. (Hist. Nat. des 

 Ins. ii. p. 471), from Java. The latter has been hitherto con- 

 founded with Hope's species, from which it differs, inter alia, 

 in having only a very small, scarcely noticeable tooth on each 

 side of the prothorax. 



Nyctopais Thomsom. 



N. aterrimus, linea arcuata a vertice iisque ad medium elytrorum, 

 altera obhqua postica maculaque niveis ; antennis niveo annulatis. 



Hab. Gaboon. 



Intensely black, covered with a very thin and close pu- 

 bescence, except where it is gathered up to form snowy-white 

 markings — that is, a line from the mandible in front of each 

 eye, another beginning on the vertex and passing back over 

 the side of the prothorax above the spine, where it is joined 

 to a patch below it, and then over the shoulder curving in- 

 wards to the suture, from which point it proceeds for a short 

 distance longitudinally, near the apex an oblique line, directed 

 inwards and downwards, Avhich is followed by a small spot 

 at the apex itself; beneath black and shining, with the epi- 

 sterna of the metathorax and a large spot on each side of all 

 the abdominal segments white ; upper portion of the posterior 

 femora and two spots on their tibiae white ,* a broad ring of 

 white at the junction of the third and fourth joints of the an- 

 tennae, and another at the junction of the seventh and eighth. 

 Length 5^ lines. 



In Nyctojyais mysteriosus, Thoms., the only hitherto described 

 species of the genus, the Avhite markings are arranged very 

 differently, as will be seen in the figure given in the ' Archives 

 Entomologiques,' tom. ii. pi. vii. fig. 1. I have much pleasure 

 in dedicating this new member of the genus to M. James 

 Thomson, the author of that and so many other useful and 

 indispensable works on entomology.
