become more or less confluent, more crowded also towards the apex 

 and at the sides, bordered, particularly on the suture, by a rose-red 

 line, three longitudinal lines of the same colour on each, the middle and 

 exterior extending nearly to the apex ; legs rose-red, annulated with 

 black, the last two tarsal joints black ; body beneath rose-red, the 

 centre of each abdominal segment black at the base ; antennas with 

 the basal joint shorter than the third, black, the two first and base of 

 the remainder rose-red. Length 11 lines. 



Rather larger than N. thoracka, Wh., to which it bears a general 

 resemblance, but distinguished by the comparative regularity of the 

 disk, and the absence of the peculiar medio-basal fissure of the pro- 

 thorax. 



Niphona pannosa. 

 N. subangustata, grisescente tomentosa, variegata ; prothoracis lateribus 



tuberculiferis ; elytris basi piloso-cristatis ; tibiis anticis rectis. 

 Hab. Cambodia. 



Rather narrow, the male broader, covered with a dense, very pale- 

 greyish tomentum, spotted with a darker or mouse-coloured grey ; 

 head rather small ; eyes and lip black ; antennae rather more than two- 

 thirds the length of the body, dark grey with very pale spots ; pro- 

 thorax narrower than the elytra, subtransverse, irregularly tuberculate, 

 especially towards the base, the side with a few short tubercles, parti- 

 ally disposed in two rows ; scutellum transverse ; elytra broadest at the 

 shoidders, gradually narrowing towards the apex, irregularly costidate 

 especially towards the apex, coarsely punctured, the base on each side 

 with a short, narrow, erect tuft of hair, the apex subtruncate, pale 

 greyish, darker posteriorly, so as to appear as a band, the shoulder 

 sometimes dark brown ; legs closely covered with short hairs, pale, 

 spotted with darker grey ; abdornen'Jiairy at the sides, with dark -grey 

 spots, the sterna reddish brown with paler spots. Length 8 lines. 



N. cylindrica, White, differs in its extraordinary fore tibiae, and 

 in its greatly developed lateral tubercle ; and N. Ferdinandi, Paiva, 

 in the absence of the basal crest of the elytra, ifec. In the latter 

 species the claw -joint is scarcely half the length of the three pre- 

 ceding, while in others it is as long as the rest together, — another 

 instance of the shifting characters of the Longicorns, and so far of 

 greater importance as the large claw-joint generally marks its pos- 

 sessor to be a " twig- climber," in distinction to the short-clawed 

 species, which are principally found on the trunks of trees. 



Niphona exeisa. 



N. angustata, nigra, pube grisea tecta ; prothorace profunde trisulcato ; 

 elytris postice attenuatis, apice divaricatis, singulis fortiter emarginatis. 

 Hab. Cambodia.
