that botli of tliem are identical with the insect which Mon- 

 trouzier erroneousl)' referred to the genus Sympycna. 

 Montrouzier's description is in the following terms : — 



" Si/mpecma Ochracea (Montrousier), Kanala. Long., 

 0™,045-0™,050. Tete noire. Corselet jaune d'ocre avec une 

 ligne mediane et deux de cbaque cote, noires. Les 5 premiers 

 Segments de F abdomen jaune d'ocre. Bout de Vahdumen, 

 Pieds, Parastigmas, noirs.^' 



Brief as it is, the description is not free from inaccuracies, 

 for it is really the first six segments of the abdomen, and 

 not the first five merely, which are ochraceous, and only two 

 of the remaining segments are black, the two terminal ones 

 being dull blue. At the same time, the species in question 

 is immediately recognisable, not only because of its large 

 size and striking scheme of coloration, but also by reason of 

 the denseJy-veined wings and the forcipate anal appendages 

 implied in the original generic reference. 



The dimensions of Montague's specimens are : — 



Mt. Mou Abdomen 35'5 mm. Hiud wing 26-5 mm. 



(incl. anal append.). 



Bale Ngo Abdomen >40'0 mm. „ „ 30"5 „ 



(bent in several places). 



Mt. Canala (1) . , . . Abdomen 42-5 mm. „ „ 31"o „ 



Mt. Canala (2) . . . . „ 42-5 „ „ „ SO'O „ 



In total length these specimen's vary from 45 mm. to 

 52 mm., a somewhat greater difference than the range 

 indicated by Montrouzier (45-50 mm.). The measurements 

 given by Ris for the male sex (abdomen 43 mm., hind wing 

 29 mm.) agree fairly well with those of three of tlie males 

 in the present collection, but the specimen bearing the 

 earliest date, that from Mt. Mou, is considerably smaller 

 than the others. 



In the wings of this species the anal crossing is variable 

 in position, and may be either before, at, or after the level of 

 the first anteuodal. 



Subfamily Protoneurin.^. 



Genus Isosticta, Selys. 



Tsosticta is typically a New Caledonian group, and both 

 of the two species which have been described from that 

 island were apparently met with by Mr. Montague. In 

 addition, he was fortunate enough to discover a third species,
