there. The Isle of Man is a station between England and 
Ireland, and may contain some species which do not inhabit 
the latter country. The Ichneumonidae of this island have 
not been enumerated, and I conclude with a list of the species 
that I found there in 1869; I am indebted for the names to 
the Rev. T. A. Marshall:—Ichneumon lineator and albi- 
cinctus, Phaeogenes melanogonus, Amblyteles divisorius, 
Phygadeuon fumator, assimilis, binotatus and vagabundus, 
Cryptus moschator, viduatorius, titillator and analis, Hemi- 
teles tristator, oxyphimus, tenerrimus, aestivalis and similis, 
Sagaritis zonata, Limneria obscurella, areolaris, mutabilis, 
bicingulata ? incrassata, exareolata, erucator ? and notata? 
Mesochorus thoracicus and confusus, Pyracmon obscuripes, 
Perilissus subcinctus, Mesoleius dubius, sylvestris and semi- 
caligatus, Tryphon trochanteratus, Campoplex pugillator, 
Bassus albosignatus, laetatorius, pectoratorius, pictus, graci- 
lentus, cinctus and compressus, Exolytus laevigatus, Atrac- 
todes exilis and croceicornis, Pimpla brevicornis and Turio- 
nellae, Polysphincta tuberosa, Glypta mensurator, Eclytus 
ornatus, Meniscus catenator, Cteniscus flavilabris.— Francis 
Walker. 
Larva feeding on the Roots of Enanthe crocata .—I should 
be greatly obliged if you could give me the name of, or any 
information respecting, the enclosed larva. I found it, with 
others, yesterday, eating the tuberous roots of (Enanthe 
crocata.— George Roberts; Lofthouse, Wakefield. 
[1 never saw the larva before to the best of my recollection, 
but have found very similar ones feeding on the simple roots 
of Phellandrium aquaticum. 1 emphasise the word “simple” 
because, although the two plants are usually placed in juxta¬ 
position in our lists, the tuberose roots of the (Enanthes 
present a pabulum for insects very different from those of 
Phellandrium. The larvae, which I found feeding on the 
Phellandrium, produced that curious weevil, Lixus pro¬ 
duct u s . — Edward Newman.] 
Filaria parasitic on a Silphid. — I have received, from an 
anonymous correspondent in Ireland, a specimen of Phos- 
phaga subrotundata, with a Filaria of unknown species 
protruding several inches from the anal extremity, and of so 
large a size that it is difficult to understand how it could have 
inhabited so small an animal, and yet both maintain their
