Food. The food of both larvae and adults consists of 

 feathers (the barbs), barley, oatmeal, sunflower seeds, seeds 

 found in bird excrement, rice, dead crickets and dead larvae 

 of their own species. 



Exceptionally long duration of larval stage. The species 

 is generally annual in its development, but not without excep- 

 tion. The eggs are deposited in early summer ; in August the 

 larvae are full-grown, but go on feeding until about March, 

 when they usually pupate, but some go on longer. In the ma- 

 terial of T. obscurns taken full grown in October, 1913, I 

 have three still feeding in the grown larval state now, No- 

 vember 16, 1914, and they seem to be healthy, and in good 

 condition, while their sisters have done their share in propa- 

 gating the race and died long ago. 



Color. The color of the larva of T. obscurus is dark 

 brown, while the entire pupa is cream white and remains so 

 until about to transform into an adult; then first of all the 

 legs and antennae assume a reddish brown color, then the 

 head and finally the entire body. The adults at transforma- 

 tion are also of this brownish color, but gradually become 

 darker until after a few days they are of a dull, piceous black 

 color. 



Three new Species of Japanese Orl Flies (Neur., 



MegaL). 



By WARO NAKAHARA, Tokyo, Japan. 



Amongst recent additions to my collection from different 

 parts of Japan are the following three species of Sialis which 

 are evidently undescribed. Although as ordinary-looking 

 as the others, they possess anal appendages very different 

 from those of any other known species. 



Sialis diminuta n. sp. (Text-fig, l). 



Head black with about ten obscure brownish longitudinal streaks, 

 of which the median two are very distinct, on caudal half ; maxillary 

 palpus ochraceous brown, excepting the basal joint which is black; 

 labial palpus totally blackish ; antennae black. 



Prothorax evidently wider than the head, rounded on the anterior
