Laxenecera albicincta with a Dammar-bee (Melpona); one 
of Lophonotus ? ustulatus with a Chalcidid. 
Asilid flies and their prey were also presented by the 
following naturalists :—

sylvatica, from Puerto de Pajares, N. Spain (1904), presented 
by the captor, G. C. Champion, Esq.

by Dr. T. A. Chapman: Saropogon ? frontalis with Antho- 
myid fly, Mydaea sp.; Laphria flava, with Formica rufa, 6 ; 
2 Machimus ? chrysitis, with the bee Andrena fuscipes and the 
grasshopper Gomphocerus sibericus, respectively; Lfpitriptus 
znconstans (probably), with the Pyralid moth Cleoleobia 
angustalis; 12 Dasypogon diadema (3 8,9 9), with Coleoptera, 
Diptera and, in 7 cases, Hymenoptera.

the captor, Rev. F. D. Morice, M.A., Queen’s College. 
Laxenecera flavibarbis carrying Apis florea, probably col- 
lected by T. B. Fry, Esq., at Poona, about 1888, presented by

Damalina myops 2% devouring MWelipona vidua % from 
Maymyo, Upper Burma (Sept. 5, 1898); presented by the 
captor, Col. C. T. Bingham. The example is all the more 
interesting because the predaceous fly is a beautiful mimic of 
the little bee upon which it was preying. 
The remaining Asz/zdae with prey are British species, and 
all except one from British localities :—
