of the segment, raediaa spots probably "well developed ia 

 fresh specimens ; underside greyish yellow, with short white 

 pubescence. Legs blackish, the tilnte reddish, pubescence 

 black; fore coxje with very thick yellowish-white hairs; all 

 femora with some pale pubescence. Wings clear, the first 

 posterior cell slightly narrowed at border ; veins reddish 

 yellow at base and on foz'e border, darker at apex ; stigma 

 yellowish ; no appendix. 



Bigot's type is in such bad condition, it is difficult to 

 distinguish any pubescence on the eyes, and the wings have 

 an appendix ; the first posterior cell is also rather narrower 

 at border. In spite of these differences, it is so like the 

 Walker type in shape of forehead and face, and is so exactly 

 similar in the abdomen, that there is little doubt of its being 

 identical with Z>. plana,

Two males from Katabomba, Blue ^Its., New South

A small blackish species, with white- or pale yellow-haired 

 median spots on the second, third, and fourth abdominal 

 segments, the last two or three segments almost wholly 

 covered Avith golden-yellow hairs and a patch of white hairs 

 on the sides of the second segments ; the males have the 

 abdomen largely fulvous in colour. 



Pangonia aurata, Macq., from the description is probably 

 identical Avith this species, but, not having seen the type, 

 Walker's name is retained.

Having seen Bigot's type, I find my species is the same. 



The types of Z). minima in Brit. Mus. Coll. came probably 

 from Moreton Bay, Queensland, others from Queensland. 

 There are three females from Herberton and Kuranda and
