THE CADDIS-FLIES {TRICHOPTERA) OF JAPAN. I.— 



FAMILY PHRYGANEID^. 



BY WARO NAKAHARA, HONGOKU, TOKIO, JAPAN. 



Through the kindness of Mr. Miyake, who has generously 

 permitted the free use of the valuable literature and collections 

 in his possession, and has given me much valuable advice, I have 

 recently had the opportunity of studying Japanese caddis-flies or 

 Trichoptcra. The purpose of the present study is to record the 

 species known from Japan, offering such notes as may suggest 

 themselves, and to describe any forms that appear to be unknown. 



The present paper deals with the family Phryganeidae, which 

 includes some of the most beautiful caddis-flies in the world. 



FAM. PHRYGANEID^. 



Genus Neiironia Leach. 



1. Neiironia regina Maclachlan. 



Holostomis regina MacLachlan — Journ, Linn. Soc. London, 

 Zool., XI, p. 104 (1871); Matsumura, Thous. Ins. Jap., i, p. 165, 

 PI. XII, fig. 11, 9 (1904). 



Neuronia regina Ulmer — Cat. Coll. Selys, Fasc. VI (1), p. 6, 

 figs. 1, 2 and 3, PI. i, fig. 1 (1907) ; Ulmer, Gen. Insect., PI. 

 XXIX, fig. 3 (1907). 



This magnificent species, which is common in China, as well 

 as in India, is not rare in Japan. 



The manner of flight of this species resembles that of a certain 

 moth. Occasionally they are found on the bark of trees closely re- 

 sembling the colour of the forewings, which always cover the ab- 

 domen and beautiful hind wings, when they are at rest. 



Already reported from Hokkaido and Honto. 



2. Neuronia reginella sp. nov. 



Head blackish, clothed with brownish hairs, especially on the 

 face; vertex wholly fuscous; ocelli brown; labial palpus consisting 

 of four joints, brown; maxillar palpus four-jointed, the last joint 

 more slender than others and fuscous; all the others mostly brown 

 and each thickened at extremity. Antennae lost, except two basal 

 joints. Prothorax light brown with a median longitudinal im- 

 pression, clothed with long, fuscous hairs. Meso- and. metathorax
