7. Family: Thaumetopoeidae. 
This almost purely palearctic family as to which we refer the readers to Vol. II, p. 143, sends only 
one offshoot across the frontier of the Indian fauna: 
Genus: Thaumetopoea Hbn. 
Th. cheela (51 c) Mr. This processionary caterpillar has the size between Th. processioned (Vol. II, 
t. 21 k) and pinivora (ibid.). — The colouring and marking is almost exactly as in pityecampa (ibid.), but the 
transverse shades in the marginal area are absent, and the median and distal undulate transverse bands are 
hued with yolk-colour on the sides facing each other. From Simla in North India; no particulars known about 
their habits.
