250 Mr. R. M‘Lachlan’s Descriptions of 
cellula thyridii, the other in the sixth apical cell. Posterior wings 
purplish-fuscous, a very broad orange-coloured band occupying 
almost the entire apical third; the extreme apex fuscous, with 
orange-coloured veins running through it. Legs with orange-- 
coloured femora, and black tibize and tarsi. Abdomen dull blackish, 
the segments narrowly margined with greyish. In the male 
the superior appendices are very small and nearly concealed by 
the Jateral margins of the last segment ; app. inf. up-curved, trian- 
gular, acute and black; penis furnished with an enormously 
swollen testaceous apex. 
This species was insufficiently characterized by Mr. Adam 
White ; having recently received some remarkably fine specimens, I 
have drawn up the foregoing description. I have removed the 
species from the genus in which it was placed by Mr. White, 
because the neuration differs in the sexes, as in Phryganea gran- 
dis (that is to say, the female has an additional apical fork), 
whereas in Holostomis phalenoides, &c., the neuration is alike in 
both sexes. The antenne are finer and shorter than in P. erandis, 
and the bright coloration of the wings contrasts strongly with 
our dull-looking species; the pubescence is also much less 
marked; the neuration, however, proves that it should be located 
in Phryganea.

L. magnitudine et facie omnino ZL. punctatolineati ; sed alarum 
anticarum margine apicali profundius exciso. (Appendicibus 
analibus defectis.) ?. 
Habitat in Japonia. 
In Mus. Brit. 
In size and coloration entirely similar to the European Z. punc- 
tatolineatus, De Geer (umbraculum, Kolenati), but differs re- 
markably in the apex of the anterior wings, which is more pro- 
duced in the costal portion, and afterwards much more deeply 
and irregularly excised ; these wings have the two rows of dots 
or streaks precisely as in the European species. The single ex- 
ample is a female in good condition, excepting the apex of the 
abdomen, which has been destroyed, and hence I am unable to 
make a comparison of the anal appendices.
