longest, the fourth, fifth, and sixth become shorter and 

 shorter. 



Prothorax : semi-elliptical, broader than long, narrower 

 than the base of the elytra. The basal margin is almost 

 straight except for a slight sinuation near the scutellum. 

 The explanate margin is broad and gently reflexed, so that 

 the upper surface is concave. The central region or the disc 

 is convex, smooth, and impunctate. Owing to a peculiar 

 transparency of the chitin, elongate bunches of fibrous struc- 

 ture are visible. 



Scutellum : triangular, surface impunctate. 



Elytra: broader at the base than the prothorax. Posterior 

 to the scutellum there is a conical pointed hump. The 

 humerus is raised and convex. The surface is plain and has 

 scattered rows of punctures. Nearer the suture the rows are 

 far apart from each other, each row consists of groups of 

 punctures of twos or threes in a longitudinal line separated 

 by considerable distances. The punctures are slightly coarser 

 and the rows are closer near the margin. 



Underside : the same colour as above, but more shining. 

 The claws have the usual comb-like structure both on the 

 inner and outer side. 



Described from sixteen examples. 



Eastern Himalayas : Darjeeling district, alt. 1000-5000 ft., 

 May, June, and July, 1912 (Lord Carmichael) ; Pashok,

Aspidomorpha spaethi, sp. n. 



Body rotundate. The colour is dirty brown with a 

 greenish tinge, shining. On the underside of the explanate 

 margins at the four corners, viz., the anterior and posterior 

 lateral angles, there are deep red-brown patches which show 

 through on the upperside. Posterior to the scutellum there 

 is a conical pointed hump. 



Length 9-10, greatest breadth 8-9 mm. 



Head : it is entirely concealed under the explanate margin 

 of the prothorax. The clypeus is rather short, so that the 

 mouth-parts are more approximated to the base of the 

 antenna?. The basal six joints of the antennae are elongate, 

 the apical five are thicker, more hairy, and having more 

 greenish tinge, the last two joints are black. The first joint 

 is long and club-shaped, the second short, the third elongate, 

 longer than fourth and many times longer than the second ; 

 the fourth, fifth, and the sixth become shorter and shorter.
