LASIA. 163 



very small; squamae pale yellowish, the upper ones small, the 

 lower ones very large and pubescent. Halteres yellowish. 



Length, 12 mm. 



Described from a single perfect S in the Indian Museum from 

 Kurseong, 6000 ft., 26. viii. 1909 (D'Abreu). 



This species is undoubtedly a Pialea, though it offers a slight 

 variation from the venation of the type species,* and the shape 

 of the abdomen is different. In my remark after my original 

 description of auripila about Westwood's figure of the antennae, 

 I overlooked bis statement in his description of the tubercle on 

 the face and the fact that the antennae are placed on the under- 

 side of it. This fact further convinces me that my species is 

 correctly placed in Pialea. 



Subfamily CYRTIN^E. 



Protborax not forming a dorsal shield in front of mesonotum. 

 Third antennal joint normally short, with apical arista or hair- 

 like rays. 



Three genera are Oriental, and are easily distinguished as 

 follows : — 



An additional cell in wing above the disca.1 and 



about as long Lasia, Wd., p. 163. 



!No such cell. 



Costa with an angular projection at tip of 1st 



longitudinal vein; antennal tip with three [p. 165.

 Costa without such projection ; antenna? ending [p. 168.

Genotype, Lasia splendens, "Wied. (Brazil). 



Body of the usual Cyrtid type. Head with eyes bare, con- 

 tiguous in both sexes, facets very small, of uniform size ; no 

 ocelli ; proboscis from a little shorter to a little longer than the 

 body, narrow, cylindrical ; palpi apparently absent or obsolete. 

 Antennas 3-jointed, porrect, approximate at base, diverging; 1st 

 joint cylindrical, short ; 2nd broader than 1st, wider towards the

t Kertesz in his catalogue ranks Lasia as synonymous with Panops, Lam. 

 (Ann. Mus. d'Hist. Nat. iii, p. 263, 1804). Nearly all the species have been 

 described under Lasia,, and, as Verrall accepts it without comment, I follow 

 him. It is a moot point if Lasia should belong to the Panofin/e or Oyrtinje.
