ON A FEW TACHINID7E AND TIIKIR HOSTS. 273 



Baumhaueri gracilis. 

 A single dead specimen of this species, named by Mr. Piffard, 

 was sent by Mr. Clutten, who bred it from an unknown species 

 of Lepidoptera at Burnley, in August. 



Myiohia inanis, Fin. 



On October 9th Mr. Clutten sent two Tachinid puparia from 

 Halifax ex Spilosoma (Arctia) lubricipeda, and two others ex dug 

 pupae of Tceniocampa (probably) instabilis, from Burnley. Unfortu- 

 nately the two former died, and their species was undetermined ; 

 but of the two latter, one was emerged with very tiny wings at 

 10.30 a.m. on 22nd June following, and its wings were not fully 

 developed the same evening, though by the morning of 23rd 

 they were fully expanded — how different from those of S. hortu- 

 lana, above ! 



Erigone radicum, Fab. 



From Arctia lubricipeda, Mr. Wigin bred eleven puparia of 

 this fine species at Methley, near Leeds, in October, and ten of 

 these emerged between the 5th and 23rd of the following June, 

 though only two remained alive at the latter date. They were in 

 all degrees of. development — five with perfect wings, one fully 

 expanded but crumpled, two reaching apex of basal abdominal 

 segment, one emerged but not at all developed, one attached to 

 its puparium by a leg, and two with only their heads protruded. 



Plagia ruralis, Fin. 

 Mr. Clutten has twice sent me batches of this species, bred in 

 both cases at Burnley from Pliisia iota. The first I received on 

 3rd August, the second on 16th June. It is a gregarious para- 

 site, and the two larvfe-skins I possess are each a mere bag dis- 

 tended by six close-packed puparia of the Hy, which are placed 

 somewhat irregularly, transversely, or obliquely. 



Plagia curvinervis, Zett. 

 One specimen of this species was received on 25th May from 

 Mr. W. M. Christy, who writes that it " emerged from a pot con- 

 taining pupae of gracilis and one myrtilli from the New Forest, 

 and Dianthoecice from West Sussex. As the gracilis and their 

 ichneumons have ceased emerging for more than two weeks, 

 probably these flies are referable to the Dianthoecice." 



Digonochata spinipennis, Mg. 

 I bred this species in the winter of 1895-90, in a box contain- 

 ing, as far as I am aware, only Sculijtus intricatas, at Ipswich 

 (for Tachinids on Coleoptera, cf.'E.M.M. 1894, p. 107, &c.) ; and 

 again, on 14th May, one emerged from its puparium, which I had 

 found beneath the pine-bark of a railing at Sproughton, near 

 Ipswich, on 9th of preceding April.
