The present part of the ' Illustrations ' contains an account of a collection of Macro-Lepi- 
doptera Heterocera made in the district of Kangra by the Rev. J. II. Hocking in the years 
1877-79j chiefly at Dharmsala. 
Mr. Hocking has kindly supplied me Tvitli the following particulars as regards the district 
and localities where he collected the insects : — " The Kangra district extends from tli(> 
Ravee to the Sutlej^ and comprises 8000 square miles of country. In addition to Kangra 
proper^ extending from Hooshiarpur to Bygnath on the Mundi boundary, the district includes 
Kiiluj a valley at the foot of the Rotang Pass, where the Blue Beas, one of the five rivers ol" 
the Punjab, takes its rise and spends its infancy and youth, and has in its immediate neigh- 
bourhood, and under the District Officers, the important and picturesque States of Mundi, 
Suchet, Chumba, Golcir, Lumbagiraon, &e. Dharmsala is the Headquarter Station of the 
District Officers, and is G2U0 feet above the level of the sea ; Kangra Fort standing some 
2300 feet in the valley, which slopes gradually from Puthankotc, on the plains of the 
Punjab, to Palampore, where the elevation is 4000 feet. The district extends to the boun- 
daries of British Thibet at the head of the Kulii valley, and its highest mountains reacli 
to 18,000 feet, those in Lahore (just over the boundary) rising to 21,000 feet." 
The number of species amounts to upwards of 780, and many of them were reared from 
larvae, of which a very instructive series was prepared by Mr. Hocking by inflation and is in 
an admirable state of preservation. 
As the collection is evidently sufficiently complete to give a good idea of the composition 
of the Lepidopterous Fauna of this district, it seemed useful not to limit this part of tho
