victims ; ‘‘ bringing the extremity of its body close to the bank, yet not 
touching it, the small white egg being seen to be thrown with a short jerk 
against the bank” (Ent. Mo. Mag., xiv., 196). On several occasions he 
noticed very closely the spot in the rough and cracked earth, and repeatedly 
satisfied himself that the egg was not thrown into any burrow, though 
numerous around. This circumstance, as Professor Riley remarks, ‘* would 
also imply that, as in the case of the blister-beetles, the newly-hatched 
larva must seek its food, and strengthens his suspicion that it would be found 
to be much more active than the mature larva” (/. ¢c., p. 269). It may be 
deemed highly probably that these “ locust-parasites,” so closely allied to the 
above-mentioned Bumbylius, may resort to a similar mode of depositing 
their eggs, with corresponding results. 
In many instances a retardation of development has been noticed in 
the American species, as in the blister-beetles, until the second year, and, 
on one occasion, even until the third year in the latter; whereby, as 
Professor Riley observes, the occurrence of migratory locusts at irregular 
intervals, in particular localities, would afford their parasites a better 
opportunity of finding appropriate food for their larve, and of thus 
perpetuating the species. 
With regard to the possible introduction of these locust-enemies into 
Cyprus, it is by no means improbable that they may already exist there as 
elsewhere; but judicious protection might doubtless do much towards 
promoting their increase, and the consequent limitation of locust ravages. 
Characteristic figures and descriptions of the fly in its various states should, 
therefore, be widely circulated among the Cyprus cultivators for the pre- 
servation of these benefactors; whereas when indiscriminate destruction of 
the ege-pouches is practised, as now, obviously the friend is undergoing the 
same process of extermination equally with the foe. We should also 
recommend that attempts be made to increase the propagation of the 
former by importations in the early autumn, before the larve quit their 
provisional abodes; which we are disposed to believe might best be done 
by sending the cases promiscuously and unopened from those localities 
where a large percentage of these larve had been verified as likely to occur 
therein; those cases which are subsequently found to contain the parasite 
being forthwith interred with their inmates, broadcast in single layers, at 
suitable stations and at the requisite depth, in uncultivated soils; after 
which the Jarve will issue therefrom in October and November to construct 
their own cells in the earth. A similar process should be resorted to with 
any which may be found on the spot; while, in both instances, destroying 
those egg-pouches which are not thus tenanted by the parasite. 
We annex figures of Mr. Calvert’s specimens in their several stages, 
which have been prepared under the direction of Mr. Charles 0. Waterhouse, 
of the British Museum. This species does not occur in the collection of
