Longico7'nta Malay ana. 687 



Hab. — Java. 



Black ; head and prothorax with a slight grayish pubes- 

 cence, the latter shortly ovate, its base with a pure white 

 border ; scutellum triangular ; elytra rather short, a spot 

 behind the scutellum and three narrow directly trans- 

 verse bands pure white, the first band midway between 

 the base and middle, the second behind the middle, the 

 third at the apex ; body beneath dark brown, posterior 

 edges of the metasternum and of the first two abdominal 

 segments at the sides, white ; legs and antennte pale red- 

 dish-ferruginous, the first three joints of the latter red- 

 dish fulvous. 



Length 2 lines. 



(The figure is very much broader and more robust 

 than the insect is naturally.) 



Demonax ? polyzonus. 



D. nigro-cinereus ; elytris medio et apice nigro- 

 cinereis, basi nigris, fascia arcuata alba, pone medium 

 fascia lata nigra, dein fascia cinerea. 



Hah . — Sarawak . 



Dark ashy; prothorax with four rather indistinct 

 black spots, two apical, two median, the base with a 

 narrow border of snowy -white; scutellum semicircular; 

 elytra rather short, their apices truncate, the angles not 

 produced, the base black, with a snowy-white arched 

 band within the black portion near its posterior border, 

 the rest of the elytra to the middle dark ashy, then a 

 broad straight black band behind this, pale ashy, gra- 

 dually deepening into dark ashy; body beneath grayish- 

 ashy, metasternum pale ashy, bordered at the sides and 

 posteriorly with white ; legs black, paler outwards ; an- 

 tennae dark brown, with an ashy pubescence, the last four 

 much shorter than the preceding joints. 



Length 5| lines. 



The two specimens before me appear to be male and 

 female ; if so, the sexual difierences are almost inappre- 

 ciable; in both, the antennae extend but little beyond 

 half the middle of the body, and the body is shorter than 

 is generally the case in this genus. It will eventually 

 have to be separated from Demonax. 



My Clytus Balyi approaches Demonax in the length of 

 the antennae, but the joints are not spined. It forms the 

 type of a genus which I propose to call Elezira.
