Longicornia Malayana. 635 



W-shaped figure), the third band arched in front, the 

 fourth broad and apical; body beneath black, the sides of 

 the sterna and first abdominal segment, and the whole of 

 the second, chalky- white ; legs and antenna3 blackish, 

 the latter paler in the middle, and the tarsi also paler. 

 Length 5 lines. 



A stouter form, apparently, than either of the two 

 preceding, and remarkable, to a certain extent, for its 

 larger eyes, which are more than usually approximate in 

 front. 



Demonax mulio. 



T). gracilis, cinereus; prothorace satiate ovato, bimacu- 

 lato ; elytris modice elongatis, fasciis quatuor 

 cinereis, secunda anguste triangulari et apice ad scu- 

 tellum ascendente. 



Hah . — Sarawak . 



Slender, ashy ; head somewhat short and broad below the 

 eyes ; prothorax rather broadly ovate, with two indistinct 

 blackish spots before the middle ; scutellum curvilinearly 

 triangular, the apex rounded; elytra moderately elon- 

 gate, black, with four ashy bands, the first basal, the 

 second narrowly triangular with the apex touching the 

 scutellum, and the sides ascending towards the shoulders 

 and uniting with the basal band, the black space on each 

 elytron forming an elongate oblique line, the third band 

 arched in front, the fourth apical; body beneath ashy, 

 with the last three segments black; legs blackish, tarsi 

 pale ; antenna with the first four joints dark, the re- 

 mainder whitish. 



Length 4^ lines. 



The coloration is like the preceding, but the second 

 band is further from the first and very narrowly trian- 

 gular; the head is very much broader, and the eyes are 

 of the normal character. 



The three next species form a small group possibly 

 distinct from Demonax; each is described from a single 

 specimen — two females and a male, apparently. They 

 differ principally in habit, in their small and delicate 

 form, and in the antennge not being setaceous, but gra- 

 dually (although slightly) thicker outwards, with the 

 terminal joint ovate.
