describes it as yellowish. Abdomen rufescenl beneath. 

 Hind tibiae and tarsi yellow, except the apices of the former. 

 which are black abdominalis, \Y. F. Kirby. 



Type in B.M. '" West Australia, Swan River." 



.'!. Legs, including the femora, pale yellow. This is apparently 

 the smallest of the species — aboul 5| mm. long. 



nitidus, \V. F. Kirby. 



Type in B.M. " West Australia, Swan River." 



- Larger forms — about 8 mm. long. At least the femora of all the 



legs are black or fuscous 4. 



4. Four posterior legs uniformly dark throughout. Face, tempora, 

 hypopygium with the genitalia, etc., and the front tibiae and 

 tarsi yellowish, the rest of the body metallic (chalybeous) 

 with reflections varying in different lights between blue-green, 

 indigo, etc. Wings clear . . . hyalinus, W. F. Kirby. 



Type in B.M. " West Australia. Swan River." 



- Hind tibiae paler beneath than above. Otherwise quite like 



hyalinus, except that the wings appear to be som'ewhat 

 darker sobrinus, W. F. Kirby. 



Type in B.M. " Australia >. " 



The localities given above are cited from Kirby's List. 

 It would seem from them that the genus is likely to be 

 confined to a single locality (Swan River); but if so, and 

 if the above are all really distinct species, it is hard to see 

 why they should all be represented by " unica." (Of course 

 more material may exist, though apparently unrecorded, 

 in Australian museums; in which case it is very desirable 

 that some competent local entomologist should revise the 

 genus properly.) 



PERGA, LEACH (AND XY LOPE RCA, SHIP?). 

 SYNOPSIS OF THE SPECIES. 



Perga differs from any Northern genus in many significant 

 respects, e.g. — 



I. Its Larva (PL XV, Fig. 17) has no ventral prolegs,
