INDIAN OR SPOTTED FORUST FLY. 115 
patches confluent at the inner tips behind; along the centre of the 
thorax is a short thin yellow line spreading out into a patch on each 
side so as to form a kind of anchor mark, and behind this anchor mark 
is a row of patches, three or five in number, according to the centre 
group being more or less confluent; besides these there are various 
side patches. The scutellum is of the deep pitchy or black colour of 
the thorax, marked across from back to front with three yellow patches, 
the centre one being much the largest. 
The above are some of the main characteristics of this species 
which may be distinguished with a fairly strong hand-magnifier. For 
those who wish to go into the scientific differentiation I subjoin the 
original description from the ‘Memoirs of the Wernerian Natural 
History Society.’ Characteristic differences of the nervures of the 
wings from those of other species will be found in Prof. Rondani’s 
work, previously quoted, attached to the description given by him 
under the synonym of eyyptiaca.* 
Continuing now the observations of Dr. Spooner Hart, of Calcutta, 
on September 20th he favoured me with some further remarks on the 
Spotted Indian Forest Fly, the H. maculata, relatively to the presence 
of this kind on dogs, and the power and structure of its claws; likewise 
some observations on Ticks, which I give separately further on under 
this heading. 
Dr. Hart remarked :—‘*‘ You will remember I mentioned that the 
fly visited the dog, but did not appear to revel upon it, or was not so 
much at home upon it as upon the horse; and, speaking of Calcutta 
and other parts of Bengal, I have never seen the fly in such large 
numbers upon the dog as upon the horse; in fact, you seldom see more 
than one at a time upon the dog, whereas, as already stated, they may 
exist in large numbers upon the horse.
