Ovipositor projecting a little beyond the end of the 

 abdomen ; anterior processes translucent, dark reddish 

 brown ; valves pale yellowish proximally, mostly blackish 

 distally ; styles black, with a pale liair projecting from the 

 apex. 



A second female, from Mt. Koglii, 10. iv. 14 (873), has a 

 longer abdomen (34'5 mm.) than the allotype, and fewer 

 postnodal cross-veins (14 in the fore wings and 12 in the 

 hind). In only one wing is Cuj of the same length as in the 

 males ; in both forewings it is fully six cells long, while in 

 the remaining hind wing, which is also abnormal in other 

 respects, it reaches the distal boundary of the eighth cell. 



It may be pointed out that /. robustior has interesting 

 relationships with several Australian members of the 

 Protoneurinse. In respect of venation, Ris has already 

 pointed out that it might well go into the genus Neostlcta, 

 but for the more proximal position of the anal crossing in 

 our species. The upper anal appendages, including the 

 inferior tooth, are not very unlike those of Nososticta sulida, 

 Selys, although the lower appendages are quite different.

This specimen, which lacks four segments of the abdomen, 

 has been seen by Dr. Tillyard, and. identified l)y him as an 

 andromorphic female.

This species was described from a unique male from 

 New Caledonia, and appears to be the Oceanic representative 

 of -4. argentea, Tillyaid,from Queensland. It is also known 

 to occui' in the New Hebrides, and the anal appendages have 

 been figured by Tillyard from males received from that 

 archipelago (Proc. Linn. Soc. N. S. Wales, xxxvii. p. 461, 

 pi. xlviii. figs. 13, 14, 191-)). The superior appendages, 

 however, are shown with "a large basal black patch,"' 

 whereas the two unbroken specimens from ]\It. Canala have 

 the upper appendages unicolorous reddish brown. In this 

 respect our material agrees with the type, and the New 

 Hebrides form has evidently taken on a local character. 

 De Selys compared his very adult type of A. ex.sudans Avith 

 what he considered to be A. pygmcea, Ramb., although he
