On Neuroptera from Western China. 421 



XLVI. — On Two small Collections of Neuroptera from Ta- 

 chien-hi,in the Province of SzecJiuen, Western China, on the 

 frontier of Thibet. l?j RoBEKT M'Laciilan, F.R.S. &.C. 



For the materials from which this pajior has been (hawn up 

 I am inclcbtod to my f;ood friend Mons. Rene Oberthiir, of 

 Kennes, who obtained them from his collectors in the above- 

 mentioned locality. Ta-chien-lu is situated, I believe, 

 at a considerable elevation. Tlie number of new forms 

 in such com])aratively small collections is remarkable and 

 significant. In several resjiccts the affinities are with Japan 

 rather than with the Himalayas, notwitlistanding the nearer 

 proximity of the latter.

Nearly a quarter of a century has passed since I indicated 

 the Japanese form of the Himalayan //. Maclachlani as 

 probably a distinct species and suggested the name regina 

 for it. Since then I have received and seen many examples 

 of both forms from their respective habitats, and they keep 

 themselves thoroughly distinct so far as coloration is con- 

 cerned. I am now disposed to attach little importance to the 

 apparently narrower wings in the Japanese insect. Of the 

 common origin of the two forms there can be no doubt, but 

 they appear to me now entitled to rank as species; and I am 

 the more confirmed in this view because in the collection from 

 Ta-chien-lu there is a single male which in colour conforms 

 to the Japanese condition and not to the Himalayan. In 

 wing-contour it is the same as the Himalayan (but so also 

 are some examples from Japan). If any differences exist in 

 the anal parts they are only very slight and remain to be 

 detected.
