Head, prothorax, body beneath, legs and first five joints of 

 antennae covered with ashy-grey pubescence ; prothorax with two 

 widely separated black spots above. Elytra black or dark brown, 

 with five bands of ashy-grey pubescence ; the first band basal, not 

 very distinct ; the second, placed obliquely outwards and backwards, 

 proceeds from a little behind the scutellum and is then bent round 

 and directed towards the shoulder ; the third crosses transversely 

 just before the middle and is produced anteriorly for some distance 

 along the suture ; the fourth, a rather broad band, is placed between 

 the middle and the apex, its front margin somewhat rounded ; the 

 fifth band at the apex. Head sparsely punctured above behind 

 the antennae and eyes. Antennae a little longer than the body in 

 the $ , exceeding it in length by the last two or three joints in 

 the $ ; third and fourth joints spined at the apex, the spine rather 

 short but distinct, fourth shorter than the third or fifth. Pro- 

 thorax nearly one-third longer than broad, feeblv rounded at the 

 sides, widest just behind the middle, furnished with a somewhat 

 obtuse median carina on the posterior half of the disc. Elytra 

 somewhat obliquely truncate at the apex, the outer angles feebly 

 dentate. Hind femora extend past the apex of the elytra slightly 

 in the $ , by nearly a third of their length in the tf , and are 

 distinctly dentate at the apex. First joint of hind tarsi about 

 twice as long as the next two joints united. 



Variation. In Burmese examples the elytral bands are ashy 

 white, the second band does not begin at the suture as in the type 

 but at a very short distance from it : the pubescence that covers the 

 body beneath is whitish on the prosternum, between and in front 

 of the coxae on the mesosternum, the episterna and the sides of 

 the first three abdominal segments. 



Length 14-19 ; breadth 3-4 mm.

352. Demonax dohertii, sp. n. 



Black, densely covered with yellowish-grey pubescence ; elytra 

 mouse-grey, marked each with an oblique spot and two bands of 

 black velvety pubescence, the spot placed on the disc at about one- 

 fourth from the base ; the first band, placed wholly in front of the 

 middle, is strongly oblique, extends from the suture to the side 

 and is there somewhat widened ; the second band broader, very 

 slightly oblique, rounded at end, is placed at a little more than 

 one-fourth from the apex and does not quite attain to the suture 

 or to the outer margin. Antennae of $ extend to middle of elytra ;
