L'lspa glabra, Wiedemann. 



Tlie male of this species is quite the most remarkable of 

 tlie }2;enus. The mid-femur is sliglitly distorted, and has on 

 the basal two-thirds of the postero-ventral surface a dense 

 scries of black bristles, -which are turned anteriorly and 

 have their apices curled, and between the bristles dense 

 black hairs which form with them a compact brush-like 

 fringe ; the mid-tibia is slightly dilated apically and has 

 some long black hairs on the apical fourth ventrally, and 

 the mid-tarsus has a dense fringe of short black hairs along 

 the posterior side of the basal segment ; except for the very 

 long tarsi, the hind legs are normal. The wings are very 

 noticeably pointed, the first posterior cell is almost closed, 

 and ends in the margin just before apex of wing ; the 

 outer cross-vein runs parallel to the margin of witig, and 

 the firth does not extend beyond outer cross-vein. There is 

 in addition a peculiar stripe of lengthened hairs on the 

 M'ing, which lies between the outer cross-vein and margin 

 and runs the whole length of apical margin of wing. 



The female lacks all those characters and looks like a 

 different species, but the first posterior cell is narrowed at 

 apex, and by that character it may be separated from its 

 allies except the next species, which has been confused with 

 it by previous authors. 



This species has two synonyms, dilatata, Wiedemann, and 

 graudis, Thomson. 



Length 8-9 mm. 



Localities, six specimens from Ceylon, as follows : male 

 and female, Trincomali, Hot Wells, 27. vii. and 17. viii. 1890; 

 female, Kauthalai, 31. vii. 1890; three females, 1. iii. 1891 

 {J. \V. Yerbury). 



L'lspa modesta, Stein. 



Male and female. — Similar to glabra in colour, but the 

 face and cheeks with yellow pollen instead of white pruin- 

 escence. The male and female are similar to glabra female 

 in armature of the legs, differing only in having the fore 

 femur with an almost complete series of yjostero-ventral 

 bristles instead of but one or two at apex. Tiie wings are 

 the same in both sexes, and differ from those of the female 

 glabra only in having the outer cross-vein slightly bent and 

 nearly erect instead of very oblique. 



Length 7 mm. 



Stein has reduced this to a variety ofassimilis, Wiedemann, 

 ])ut I regard it as a good species. It was originally described 

 from Africa, from where I have seen three females. I have
