 darkening into brown at the tips ; tibiae and tarsi brown. 

 Wings pellucid, with a very slight brownish tint ; the costal (ex- 

 cept at base) and sub-costal cells, origin of prsefurca, inner ends 

 sub-marginal and all the posterior cells clouded with brown ; also 

 margins round apex of wing clouded with brown ; stigma elongate, 

 brown ; veins brown. Auxiliary vein reaching first longitudinal 

 vein opposite or somewhat before inner end of second sub-marginal 

 cell, connected near the tip by cross-vein to costa ; prsef urea of 

 moderate length, arcuated at base ; petiole of first sub-marginal 

 cell equal in length to posterior branch of second longitudinal 

 vein ; the latter arcuated at its base, the remainder a little bent ; 

 marginal cross-vein situated beyond the middle of petiole of first 

 sub-marginal cell, and a distance equal to its length from tip of 

 first longitudinal vein ; inner end of second sub-marginal cell 

 rounded, situated a little before that of first posterior cell ; small 

 cross- vein a little arcuated, in line with inner end of discal cell ; 

 the latter at least as long as third posterior cell ; second posterior 

 cell less than half the length of third posterior ; great cross- vein 

 situated a short distance beyond inner end of discal cell ', seventh 

 longitudinal vein arcuated at its tip. 



Hah. — Sydney 1 (Masters). Three specimens. 



Ohs. — This species approaches O.-Sacken's L. luteiiyennis group 

 by the structure of the head, prolongation of collare, double dots 

 on anterior extremity of intermediate thoracic stripe, &c., but the 

 second sub-marginal cell is shorter, the posterior branch of the 

 second longitudinal vein is only a little arcuated, and the rostrum 

 is as long as the head.
