It has the size and general form of G, frivittata and the 
pattern of the head, pronotum, and seutellum is similar, but 
with the yellow lateral patches of the pronotum broader, 
leaving two rather irregular shining black stripes, which are 
finely and not closely punctured. The scutellum is mode- 
rately long, but not acute at the apex. The elytra are covered 
with whitish tomentum, except for a narrow shining mar- 
ginal line and two narrow discoidal stripes, the first running 
from the base parallel to the sutural margin and the other 
from the humeral angle, meeting the first just before the 
apex. The pygidium is thinly pubescent, not shining, and 
has a rounded patch of yellow tomentum on each side. The 
body is covered with similar tomentum beneath, except for 
a quite smooth median line. The mesosternal process is 
slender and curved.

Gazavanp: Chirinda Forest, 3800 ft. (G. A. K. Marshall, 
March, August). 
This is the smallest so far known in the group of species 
to which it belongs, and is much more variable in colouring 
than the rest, which seem to adhere with great constancy to 
a particular shade of vivid green, softened by pinkish reflec- 
tions in a certain light. The same colour is found in the 
present species, but a cobalt-blue changing to a rich purple 
is equally frequent, and our series includes one specimen of a 
fiery red. The borders of the pronotum are usually of a paler 
colour than the disc. 
H. pygmea most resembles H. alternata, K1., but, in 
addition to its smaller size, is much more hairy, the head 
and the metasternum (except a small area in the middle of 
the latter, which is quite smooth) being clothed with long 
tawny hairs, that upon the head standing erect. The 
pygidium, on the otber hand, is smooth and shining, and
