only museum enjoys a unique distinction in possessing specimens of the 
perfect insect of this Gad-fly. 
Tt is an interesting question and worthy of investigation as to how these 
bots get into the elephant’s stomach. In the case of the horse the eggs are 
laid about the knees, fetlocks, and shoulders, whence they are licked off and 
swallowed. In the case of the elephant some other method must be adopted, 
and it will probably be found that the eggs are deposited on the khurbi and 
other fodder. 
RaINOCEROS :—Gastrophilus rhinoceronis, Gyrostoma sumatrensis—Larve 
only known. These are unlikely insects to breed, Still some member of the 
Society may come on fresh rhinoceros dung, or chance on a perfect fly in the 
jungle. 
Bot-flies are sometimes to be caught round horses with a butterfly net, but 
this method is pure chance, The majority of the specimens will have to be: 
bred ; a few may be taken flying round oneself or one’s companions, and a 
few (@) caught sitting sunning themselves on the bare ground. 
B. Warble-flies: (Larve in tumours under the skin). 
Ox :—Hypoderma lineatum, bovis, 
’ DEER :—H, acieon, diana. 
Horse (?):—Z., (?) sélenus—A Warble-fly is said to attack the horse, but 
further evidence on this point is desirable, 
SHEEP AND Goat (?) :—It being almost impossible to breed Warble-flies, 
one must depend entirely on the capture of the perfect insect. In England and 
on the Continent, H. dineatwm (the Common Cattle Warble-fly) is met with not 
unfrequently in the Spring sunning itself on bare places in roads; H. bovis 
(the Ox Warble-fly) has similar habits, but is much rarer, and appears in the 
hottest part of the summer; probably all members of the genus have similar 
habits. 
_C. (Larve in the frontal sinuses, pharynx, &c., of various animals), 
_ Tur Super Gap-FLy :—MZsirus ovis—This fly may possibly be bred should 
the larve be found soon after being thrown out by the sheep. The perfect 
insect is taken occasiona|ly sunning itself on tarred palings or other hot places, 
or in dull weather between the stones of the walls and other cracks. and 
erevices round sheep folds, On these occasions the flies are very lethargic, and 
can be picked up with the forceps, but they are by no means easy of detec 
tion, as they look like dead flies spun up in a spider's web. 
_ Tur Came. Gab-Fiy :— Cephalomyia maculata—I bred this fly at Aden some 
lary brought to me by camel men, who said that the maggots had been thrown 
eut by the camels sneezing. The flies are easily reared, the maggots only.re- 
quiring some dead leaves, saw-dust, &c., for them to pupate under, This Gad-fly 
is said to infest the buffalo as well as the camel, but this requires confirmation, 
I have never seen this fly alive ina state of nature, but it ought not to be 
dificult to obtain larvee at stations in Sind, Rajputana and the Punjab,
