Kedah : Kedah Peak, 3200 ft. {Dr. A. T. Stanton), 2 ? 

 (type in British Museum ; paratype in Kuala Lampur 

 Museum). 



In the rudimentary nasus, the extreme shortness of Rs, 

 and the long fusion of Cuj with M3, as well as in the small 

 size of the cell 1st Mg, this species is very distinct. T. in- 

 conspicua, de Meij., is similar in many respects, but in 

 that species the contact of Cui with Mg is almost puncti- 

 form. In the rudimentary nasus and the shortness of the 

 verticillate hairs on the under side of the flagellum the new 

 species resembles the European T. variicornis, Schum. 



Subfam. Limnobiinjs. 

 Group L I M N o B I I N I. 



Rhipidia rostrifera, sp. n. 



^ . Head brownish-grey. Proboscis black, slightly longer 

 than the head ; palpi black, placed near the tip of the pro- 

 boscis. Antennae : first joint yellowish, dark at the tip ; 

 second joint yellowish ; third to thirteenth joints obscurely 

 yellowish, dark at the base, from wliich springs a pair of 

 long black pubescent processes ; the processes on the third 

 and thirteenth joints are not much longer than the joint, 

 those on the intermediate joints are much longer, the 

 longest being quite four times the length of a joint; 

 fourteenth joint black, simple, rather longer than the others. 

 Tliorax covered with a brownish-grey pollinosity, without 

 distinct markings, a dark central line, however, is observable 

 when the thorax is looked at from behind. Abdomen dark 

 brown ; in certain lights the hind margins of the segments 

 are whitish. Genitalia of the ordinary Dicranomyia type. 

 Legs brownish, femora lighter towards the base ; claws 

 simple. Wings hyaline with four dark brown spots on the 

 costa situated at the tip of the wing, the tip of Sc, the tip 

 of Ri, and the middle of Sc, the last two being larger than 

 the first two ; there is also a dark brown spot in the base of 

 the basal cells and another at the tip of Ax ; the tips of the 

 other veins and the cross-veins are also darkened, but less 

 conspicuously. Sc, ending opposite base of Rs, Scg near its 

 tip ; cells 1st and 2ud Mi confluent {i. e., discal cell open, 

 confluent with the 2nd posterior) ; Cuia meeting M at 

 the fork. Veins dark, except costa, Sc, and Rj, which are 

 yellow except where crossed by the dark spots. Halteres 

 with yellow stem and black knob. 



Length of body 5 mm. ; wing 5 mm.
