774 STUDIES IN AUSTRALIAN NEUROPTEKA, vi., 



Characters as given in the key on p. 771, with the following 

 additions: — Moderate-sized insects, expanse varying from 25 to 

 50 mm. ; with or without anastomosis between M and Cu in 

 fore wing. 



Genotype, Psychopsis mimica Newman. 



With rejxard to the variable character of the amount of anasto- 

 mosis between M and Cu in forewing, Text-fig. 4 shows two of 

 the variable conditions to be found in the genus. In the type- 

 species, Ps. mimica, the most frequent condition is that shown 

 in Text-fig. 4rt; but a condition resembling that shown in h may 

 also occur in one or both wings. In Ps. elegans, the commonest 

 condition is that shown in h, but there are many irregularities 

 in one or both wings. In Ps coelivarjiis, either of the two con- 

 ditions shown in a and b may be present, or the anastomosis may 

 be complicated by the presence of numerous cross-veins, or there 

 may be no anastomosis at all; this last condition is the most 

 usual one for Ps. insolens. 



Not having seen any of the African species, I cannot say 

 whether the type of anastomosis on which Navas bases his separa- 

 tion of these species, as a tribe separate from the Australian ones, 

 is of the type here shown or not: but, as he qualifies his statement 

 that M, Cu and its sector (by which, I presume, he means Cu,.) 

 are anastomosed, by the phrase "magis vel minus sensibili'" (13, 

 p. 199), I anticipate that here, as almost everywhere else, he has 

 failed to select a constant character for his subdivision, and that 

 a thorough revision of the African species will result in the com 

 plete collapse of his tribal distinctions. 



Key to the ►Specie s o f P s y c h o p s i s . 



Larger species, expanse 83 to oUnini., with detiiiite, transverse 

 fasciie in forewing, and pink or red markings near toriuis; 

 forewing with more or less prominent tornus. Dark spot on 

 hind wing placed well helotr the anastomosis of 8c, R, and Rs. 2. 



Smaller species, expanse 25 to 36 mm., with tesselated, fawn- 

 coloured, grey or black markings on forewing; tornus well 

 rounded. Dark spot of hindwing placed either upon the 

 anastomosis itself, oi- between it a'ld the apex 4.
