My. F. p. Pascoe on new Sjjecies of Lamiidtc. 209 



between the eyes not extending to tlie clypeus ; eyes larger 

 than in 2\ WalUchii] prothorax rather narrow, not turgid, 

 a stout, strong anguhir spine on each side ; scutelhini equi- 

 hiterally trianguh\r ; elytra scarcely punctured except at the 

 sides, their a])ices broadly eraarginate, with five or six jet- 

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

 with a piu-plish tinge ; mesosternnm with a large prominent 

 mammillary process; antenna) with the third, fourth, and fifth 

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



A comparatively short, nearly black species, remarkable 

 for its strongly produced mesosternnm. The other two species 

 of this genus are 2\ Wallichii, Hope (Royle's ' Himalaya,' 

 pi. 9. figs. 5 and 6), and 2\ tncincfa, 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, intei' alia, 

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

 side of the prothorax. 



Nyctopais Thomson i. 



N. ateriimus, liuca arcuata a vertice usque ad medium elytrorum, 

 altera obliqua postica maculaque niveis ; antcnnis niveo aunulatis. 



Ilab. 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 shoidder curving in- 

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

 distance longitudinally, near the a])ex an oblique line, directed 

 iuAvards and downwards, which 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 tibite white ; a broad ring of 

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

 tenna), and another at the junction of the seventh and eighth. 

 Length 5^ lines. 



In Nyctopais mysteriosus, Thorns., the only hitherto described 

 species of the genus, the white markings are arranged very 

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

 Entoinologiques,' torn. ii. pi. vii. fig. 1. I have much pleasure 

 in dedicating this new member of the genus to 31. James 

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

 indispensable works on entomology.
