A ComRimniox to the Knowledge of thk Nf.ukopterol's Insects of Solth Saoiialikn. 135 



of the species of neuropterous insects, viz., Megaloptcra, Planipcnnia, Meco- 

 pteia and Trichoptera, was not recorded from South Saghalien. In the work 

 abo\e mentioned, thirteen species, belonging to nine genera under nine fami- 

 lies, were enumerated, and five of them were new to science. In the next 

 year. Prof. NavAs (jp) recorded tlie distribution of tlie Siberian alder-fly, 

 Sia/i's sibirica M'L., to tlie region just referred to. And then Drs. Mivakk 

 {20), Okaiioto (./p, J/, j-,', j^), and Nakahaka (-'5, 2j, 2S, jo, 75) have referred 

 some of them in their contributions, but no more added. In the last few 

 years I have endeavoured to obtain some neuropterous specimens from South 

 Saghalicn with great interest, and now can recognize t\\ent)'-fi\e species as 

 occurring in the same region. These specimens were collected in 1919 by 

 Mr. E. IZAWA, in 192 1 b)- the author, and in 1922 by Messrs. T. Esaki and 

 T. Kano. Although I recognize that it does not cover two-thirds of the 

 species to be found in South Saghalicn, I presented a synopsis for the benefits 

 of future studies. As this, in the synoptic tables I have included some 

 families and genera not yet recorded from there, but in some other regions 

 of the Japanese Empire. 



Here, let me follow the list of species treated in this paper, showing 

 their geographic distribution.
