326 THE CANADIAN ENTOMOLOGIST. 



In any case it may safely be said that there is another form in 

 Japan besides A^. melaleuca, closely allied to this species. It is 

 said that the habits of this species resemble those of N. regina. 

 Habitat — Hokkaido, Honto. 



Genus Phryganea Linne. 



8. Phryganea japonica MacLachlan. 



Phryganea japonica Ma.cLach\a.n — Trans. Ent. Soc. Lond., (3) 

 V, p. 248 (1866); Matsumura— Thous. Ins. Jap., I, p. 167, PI. XII, 

 fig. 3, c^ (1904) ;Ulmer— Cat. Coll. Selys, Fasc. VI (1), p. 10, figs. 

 11, 12 and 13, PI. I, fig. 2 (1907); Ulmer— Gen. Insect., PI. XXX, 

 fig. 1 (1907). 



The markings of the fore wing of this species arc subject to 

 variation, and the material before me can be separated into two 

 types: 



(i) Those that have conspicuous fuscous lines along the cubital 

 and the fourth apical veins. 



(ii) Those that have faint and obscure fuscous lines along the 

 cubital and the fourth apical veins. 



Though there arc some other minute differences in the mark- 

 ings of the fore wing between types i and ii, I think they are not 

 worthy of specific rank, since I could not recognize any difference 

 in the genitalia, nor in any other respects, that appear to be specific. 

 Until a more comprehensive study of these two forms is published 

 I shall have to include them in one species, Phryganea japonica. 

 It would he very interesting if their life-histories were known. 



It seems to me that Ulmer's figure in the Selys Catalogua 

 represents type i and his figure in Genera Insectorum type ii 

 Matsumura's figure seems to represent type i. 



This is one of the most common caddisflies of the family in the 

 Main Island of Japan, occurring also in Hokkaido. 



9. Phryganea sordida MacLachlan. 



Phryganea sordida MacLachlan — Journ. Linn. Soc. Lond., 

 Zool., XI, p. 106 (1871) ; Ulmxr— Cat. Coll. Selys, Fasc.VI (1), p. 8,

A single female specimen in the collection of the Imperial 

 Agricultural Experimxnts Station, from Gifu, labeled "Haya-
