Macroglossum includes dark coloured “humming bird hawk moths,” 
found flying by day in bushes seeking flowers ; they are extremely abun¬ 
dant in the subtropical zone but some occur in the plains. M. gyrans, 
Wlk. ; M. belis, Cram. ; and M. pyrrosticta , Butl. (gilia, Herr. Sch.) are 
to be found, the second most abundantly. 
Chcerocampince. —A number of common forms are included in this 
sub-family. The larvae have the head and thoracic segments more or less 
retractile into the swollen metathorax, which often has lateral eye-marks. 
In Hippotion celerio, L., the larvae may be green or dark brown, both occur¬ 
ring together in all stages on the same foodplant. The genera Theretra 
and Hippotion include the common hawkmoths of the plains, moderate 
sized insects with the apex of the forewing produced slightly. The full 
fed larva pupates at the surface of the soil in a covering of leaves webbed 
up with coarse silk enclosing an earthen chamber. 
The following are the common species, with the revised and old 
nomenclature of the Fauna, and the known foodplants in India.

Collecting. —Moths are! caught on the wing by day ( Macro - 
glossince) or at dusk at flowers. Some come to light and the occur¬ 
rence of these is worth noting even if they be common species. 
Larvae aye always worth rearing if their food plant can be ascertained, 
and there is no special difficulty in this. If it is desired to obtain eggs, 
the pupae must all be treated alike as they react quickly to altered 
conditions and will not emerge together if differently treated.
