Schîzomyîa villebrunneae n. sp. 



A series of these very interesting midges were reared from several leaf 

 galls, the label on the type lot reading as follows: 8, Villebrunnea rubescens 

 Bl. üengaran-üebirge, altitude 1000 M. Cecid. No. 2, Marcellia Bd. X, 1911, 

 S. 89, No. 247, 13/IV, '14 DvL. 



This species is noteworthy in that the male antennae exhibit a distinct 

 tendency toward trinodosity. The pupa of this species is easily distinguished 

 from that of S. laporteae by the distinctly bidentate apex of the antennal horns. 



Apparently the same insect was reared form other galls on this plant, 

 the label on one reading as follows: 7, Villebrunnea rubescens Bl. Oengaran. 

 Gebirge, altitude 1000 M. Cecid. No. 1, Marcellia Bd. X, 1911, S. 88, No. 

 246, Fig. 102, 13/IV, 1914, DvL. 



A third lot referable to the same species had the following data on the 

 label: 3, Villebrunnea rubescens Bl. Oengaran-Gebirge, altitude 1400 M. Cecid. 

 No. 5, Bull. d. Jard. Bot. de Buitenzorg Série 2, No. Ill, 1912, S. 48, No. 341, 

 14/IV, '14DvL. 



Gall. The globose or ovate gall is narrowly attached to the vein on the under- 

 side of the leaf, the dimensions being 7-9 by 4-5 by 4 m.M. or even larger if the identi- 

 fication of the other lots is correct. Two types of galls are described and one figured 

 in Marcellia 10: 88-89. 



Male. Len-gth 1.5 m.M. Antennae extending to the fourth abdominal segment, 

 sparsely haired, yellowish brown, 14 subsessile segments, the fifth cylindric with a length 

 about four times its diameter and with rather distinct constrictions near the basal and 

 distal thirds, the circumfila heavy, strongly convolute and on most segments with 



distinctly elevated loops on the slight basal, 

 middle and the distal enlargements. Terminal 

 segment with a length about four times its 

 diameter, slightly constricted near the basal 

 and distal thirds, and with the apex rather 

 thickly crowded with short, circumfilar loops. 

 Palpi, first segment short, subquadrate, the 

 second narrowly oval with a length over 

 twice its width, the third one half longer, 

 more slender and the fourth one half longer 

 than the third. Mesonotum dark reddish 

 brown, scutellum yellowish brown, postscu-
