 breadth before the rapidly rounded apex ; the tegmina appear to have been 

 clear and light colored mi the disk hut broadlv obscured at base, at the 

 margins, and along the principal veins, and on the apical third broadly 

 margined throughout with brownish fuliginous, fading gradually basally.

PI. 10, Fig. 9. 



Head, as viewed from above, rounded, subtriangular, the front strongly 

 convex, the ocelli situated on the vertex, the surface of the head and thorax 

 uniform, the scutellum roundly angulated behind. Tegmina barely reach- 

 ing the tip of the abdomen, pale with bold dark markings, as follows : A 

 broad subequal stripe follows the outer edge of the sutura clavi to the mid- 

 dle of the wing, where it unites faint.lv with a narrow stripe which has fol- 

 lowed the commissural margin to the tip of the sutura clavi and distinctly 

 and broadly with a small round spot on the middle of the costal margin ; 

 the markings on the outer half of the wing are somewhat irregular, but may 

 best be described as taking the form of a broad and rude X, one bar run- 

 iiin<r from the center of the winy, just out of contact with the basal mark-

ings, to the lower apex of the wing where the margin is clouded with fulig- 

 inous, the other crossing the whole wing obliquely and recurved on the 

 costal margin. 1 do not find any existing species with markings at all sim- 

 ilar, the nearest approach being that of T. bella Walker from Silhet. 



Length of body, 7.7o""" ; breadth of head, 2 mm ; of abdomen, 2 5 mm ; 

 length of tegmina, G lnm ; breadth, 2 mm .

3. TKTTIGONIA PRISCOVARIEGATA. 



A single specimen is preserved, of which only one of the tegmina may 

 certainly be claimed for the species. This is very long and slender, three 



and a half times longer than broad, in the apical tit'tli tapering rapidlv to 

 tin- rounded tip \\ liidi is in the middle of the inner half of the tegmina : it 

 is pale \\ith hlarki.-h brown markings, which consist, first, of a narrow mar-
