II. Acanthaclisini. 



In Acanthaclisis Rambur (sens. str.) the Cu2 in tbe fore- 

 wing is bent or curved in its apical part towards the base 

 of the wing. The intercubital area (the area between Cu^ 

 and CU2) is very acute towards the base of the wing. The 

 »oblique vein» joins the Cti^ about in the middle between 

 the fork and the first branch from Cui. The intercubital 

 plicate line (partly formed by the bent sectors from Cui) 

 is very distinct and arises from the first branch from Cwj- 

 M forms nearly a straight Hne in both pairs of the wings; 

 it is only bent a little near its apex. The first branch from 

 Bs forks two or three times near its apex. The radial plicate 

 line (partly formed by the bent branches from Rs) is very 

 distinct, and it arises from the first branch from Rs. The 

 costal area rather broad and with two rows of cellules. In 

 the hindwing 1 A and Cii2 coalesce for a longer distance. 

 Both the radial and the intercubital plicate line are distinct. 

 Prothorax broader than long. 



During the last years the genus Acanthaclisis (sens. lat.) 

 is split up in several genera, and the above named characters 

 agree only with the genus (sens. str.) with A. occitanica Vill. 

 as geno-type. 



If the shape of the spurs may be considered as being 

 of generic value, it will be necessary to place the Australian 

 species fundata Walk. in a new genus, as this species has 

 not angulate spurs. The African species dasymalla Gerst. 

 has also slightly curved spurs, and in the forewing the costal 

 area is rather narrow and has only two rows of cellules a 

 little before the pterostigma.

Two females were present; one labelled »Mus. Payk.»; 

 the other »SchönherR'> and »if. Georgiana Fisch. Tauria-
