examined to see if they were favoured also, but I could not see any 
signs of the fly. Perhaps the insect was in an unhealthy state, and 
there was some peculiar smell about it which was pleasant to the fly. 
IT am curious to find out, and I leave this remarkable instance to you, 
as you may have at some time had it brought to your notice. Per- 
sonally this instance is quite new to me. I have seen certain kinds 
of larvee—ladybirds, &¢.—which have favoured ants, and the reason 
assigned for this, I believe, has long since been satisfactorily ex-

these flies, as might be expected under usual circumstances, never 
left their hold unless it was to run up my thumb, but back again to 
the bug. They kept their antennz moving all the time, much like

[The bug forwarded by Mr. Marley is the widely distributed 
Anoplocnemis curvipes, Fabry. The hymenopteron has been identified 
by Col. C. T. Bingham as belonging to the Fam. Proctotrypide, Sub- 
fam. Scelionine, and probably representing an undescribed genus and 
species. W. H. Ashmead, in his well-known Monograph of the 
North American Proctotrypide (Bull. U. 8. Nat. Mus. No. 45, 1898), 
writing on the Scelionine, states that all the species are “ strictly 
egg-parasites, scarcely a single order of insects being free from their 
attacks,’ and that the genus Hadronotus ‘is parasitic on different
