area to the costa. There is a similar poverty of spots on the 

 upper wings, and the upper surface is also almost devoid of 

 markings. The lower figure represents a normal male specimen 

 for comparison. I may add that all through the very interesting 

 mountain region of South-central France the orange-red and 

 orange-brown coloration, both in Mclitcea and in Argynnis, tends 

 to a clear cold clay-yellow-brown, especially in A. niohe, of which 

 species the ab. eris, as elsewhere in the more elevated regions of 

 France and Switzerland, appears to predominate. Specimens of 

 didyma from Cortina-di-Ampezzo exhibit a similar tendency ; 

 the fiery foxy brown of the wing pigment being in my series 

 much subdued and deadened. Both in the male and female, but 

 especially in the latter, the aberrant tendency is most marked, 

 whether on the upper or under side, while I have seen specimens 

 of Melitcea cinxia, notably some exhibited by Mr. H. Goss at the 

 Entomological Society last year, nearly approaching the extreme 

 form of didyma which I have figured. 



Q TWO NEW AUSTRALIAN CULICIDS. 



By Fred. V. Theobald, M.A. 



The following are descriptions of two new Culicids recently 

 sent me by Dr. Bancroft from Queensland. There is at present 

 a plague of mosquitoes in Queensland and other parts of 

 Australia, the two commonest species being Culex annulirostris, 

 Skuse, and C. marinus, Theobald. 



Genus Macleaya, nov. gen. 



Intermediate between Stegomyia and Culex. 



Head covered with flat scales over most of its surface, but with 

 a median line of narrow-curved scales. Palpi short in the female, three- 

 jointed, with two basal constrictions ; apical joint minute, penultimate 

 joint large, swollen apically and truncated ; the aute-penultimate 

 broad apically, becoming narrower and swollen again basally, two 

 basal constrictions looking almost like joints. The apex of the penul- 

 timate joint is studded with round spots. Palpi long in the male, longer 

 than the proboscis, the two apical joints short, rather swollen, also the 

 apex of the ante-penultimate ; hair-tufts rudimentary. Thorax with 

 narrow-curved scales ; scutellum with small flat scales on the median 

 lobe, narrow-curved ones on the lateral lobes. 



This genus differs from Stegomyia, to which it bears a strong 

 superficial resemblance, in having narrow-curved scales on the 

 centre of the head and on the lateral lobes of the scutellum. 



A single species only is known.
