34 Mr. II, Campion on 



occur there were enumerated, although not represented in 

 the collection. Argiolestes roudi, Ris, however, may be 

 synonymous with a species previously described by Mon- 

 trouzier, while Rhyotliemis graphiptera, Ramb., has been 

 evidently overlooked (Martin, Mem. Soc. Zool. Fi-ance, xiv. 

 p. 22], 1901 ; Ris, Coll. Selys, Libell. p. 934, 1913). The 

 occurrence of Tramea /oewf?', Brauer, doubtfully recorded bv 

 De Selys (Mitt. Mus. Dresden, iii. p. 293, 1878), stands in 

 need of verification. 



In 1914 large collections of insects were made in New 

 Caledonia by the late Mr. Paul D. Montague, and were 

 subsequently presented to the British Museum (Natural 

 History) by the mother of the collector. These include 

 18 species of Dragonflies, of which 5 appear to be un- 

 describid. The most important are the representatives of 

 the subfamily Corduliinse, in which group we find not only 

 the long-lost Synthemis miranda, Selys, but thi'ee ncAv 

 species of the same genus as well, besides the unexpected 

 occurrence of a new Metaphya. 



Among the Agrionidae, the material of Isosticta is of the 

 greatest interest, as, in addition to yielding another new 

 species, it completes our knowledge of the two older but 

 imperfectly-known ones. 



Of the 26 species definitely known to inhabit New 

 Caledonia, 12 appear to be endemic to that island or the 

 Loyalty group. These are : — 



Argiolestes sarasini, Ris. 



ochraceus, JNIontrouzier. 



uniseries, Ris. 



Trineuragriun percostale, Ris. 

 Isosticta spinipes, Selys. 



robuslior, Ris. 



tilhjardi, sp. n. 



Synthemis miranda, Selys. 



montuguei, sp. n. 



fiexicuuda, sp. u. 



Jenella, sp. n. 



Metaphya clongata, sp. n. 



Of the remaining 14 species, three are both common and 

 peculiar to New Caledonia (with the Loyalty Islands) and 

 the New Hebrides, namely, Agriocnemis exsudans, Selys, 

 Hemicordulin fdelis, McLach., and Rhyothemis p/iyl/is 

 apicalis, Kirby. 



The presence of Syntheniini provides a link with the
