SACRA. 
9 
extending to middle of elytra, terminal joint very elongate. 
Head very finely punctured. Thorax subquadrate, sides concave, 
anterior angles prominent but blunt, surface rather closely 
and strongly punctured. Elytra subquadrately ovate, deeply 
depressed below base and 
within shoulders behind basal 
margin, the latter raised into 
an acute ridge ; entire surface 
finely punctate-striate, inter- 
stices finely aciculate and 
wrinkled. — B . Posterior 
femora strongly thickened at 
middle, not much extending 
beyond elytra, upper edge 
strongly convex, lower with 
two teeth near apex and a 
dense patch of yellow tomen- 
tose hairs : posterior tibiae 
with a long tooth near apex, 
the latter strongly mucronate ; 
intermediate tibiae very 
strongly curved. — $ . Smaller, 
posterior femora short, less 
incrassate, a dentate ridge below, tibiae simple. 
Length 11-12 mm. 
Hob. Burma: llangoon; extending to Siam, China, and Japan. 
I have included this species as a single specimen from liangoon 
in Burma is in my collection. I have however, seen no other 
specimens from that or from other parts of India. In the variety 
pygmea the tibiae have no tooth. The comparatively small size, 
colour, and the large tomentose femoral patch serve to distinguish 
this species. In some specimens the first tibial tooth is pro- 
longed into a long process. 
Subfamily II. DONACIINiE. 
Elongate and narrow, more or less metallic, beneath strongly 
pubescent ; the species resemble certain Longicorn beetles and 
live on water-plants. Antennae more closely approximate at base 
than in the subfamilies Criocerince or Sagrince, filiform ; eyes round 
and entire ; elytra punctured in rows ; anterior coxae nearly 
touching ; basal segment of abdomen as long as or longer than 
following joints united ; claws simple. 
These insects agree with the Sagrince in the elongate basal 
segment of the abdomen, but the prosternum does not separate 
the coxae as in that group and the body beneath is clothed with 
short silvery pubescence. The posterior femora are frequently 
toothed. ^ single genus.
