of new species of Raphidia and Trichoptera, Sc. 491 
schneider’, Ratzb. and R. sericea, Albarda, from which it 
differs by the dark brown pterostigma, by the relative 
length of the first discoidai cell, and by the form of the 
genital parts. These are similar to those of L’. major, 
Burm., from which it differs by the single cross veinlet in 
the pterostigma and by four cubital cells. 
I collected two ¢ on bushes along the road from 
Philipopol to the monastery Bela Cerkva, 30th July. 
Polycentropus excisus, n. sp. 
Similar to P. flavomaculatus, Pict., in general appearance, but 
the antennz are yellow, the apex only annulated indistinctly with 
brownish. Palpi and legs yellow, and the markings on the anterior 
wings are pale yellow; the footstalk of the apical fork No. 3 is at 
least half so long as the fork. 
In the ¢ the dorsal plate is almost quadrangular, slightly 
excised on the apex. Superior appendages a little longer than the 
dorsal plate, broad. Viewed from the side their upper margin is 
rounded and the lower almost straight. From above they are quad- 
rangular, with rounded exterior apical angle. Their base is covered 
above by a large triangular lobe joined to the base of the dorsal 
plate. Intermediate appendages short, reddish-brown, escaping 
from beneath the apical angles of the dorsal plate, curved down, 
but their tip turned again upward. Inferior appendages a little 
shorter than the superior, concave inwardly and convex outwardly 
with deeply excised apical margin. Both the upperand lower edge 
are so far turned inwardly that they touch each other, forming, in 
this way, a tube opened at the apex. 
¢ unknown. 
Exp. 15 mm., length 5 mm. 
I would not have dared to describe this species from 
the single ¢ collected in Bojana, near Sophia, 20th July, 
had not the form of the appendages been so very cha- 
racteristic. 
Tinodes unidentata, n. sp. 
Body black, clothing black mingled sparingly with testaceous. 
Antenne fuscous, very indistinctly and narrowly annulated. Legs 
brown or fuscous, trochanters and knees testaceous. Anterior 
wings blackish, sparingly covered with black pubescence. Neura- 
tion distinct, similar to that of TY. dives, Pict. ; posterior wings 
similar in colour to the anterior, not iridescent. Fringes blackish 
grey.
