occur there were enumerated, although not represented in 

 the collection. Argiolestes rou.vi, His, however, may be 

 synonymous Avith a species previously described by Mon- 

 trouzier, while Rhyothemis graphiptera, Ilarab., has been 

 evidently overlooked (Martin, Mem. Soc. Zool. France, xiv. 

 p. 221, 1901 ; Eis, Coll. Selys, Libell. p. 934, 1913). The 

 occurrence of Tramea /oe'W^^, Brauer, doubtfully lecorded by 

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

 need of verification. 



In 1914 large collections of insects were made in Nbav 

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

 subsequently presented to the British Museum (Natural 

 History) by tlie mother of the collector. These include 

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

 describL'd. The most important are the representatives of 

 the subfamily Corduliinse, in which group we find not only 

 the long-lost Syntheinis miranda, Selys, but three new 

 species of the same genus as well, besides the unexpected 

 occurrence of a new Metaj^hya. 



Among the Agrionidre, 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 

 imperfectl}'^ -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, Montrouzier. 



• uniseries, Ris. ^ 



Tinneiiragriun percodale. His. 

 Isosticta spinipes, Selys. 



rohustior, Ris. 



tilhjardi, sp. n. 



Syntheinis miranda, Selys. 



inontayuel, sp. n. 



flexicauda, sp. n. 



fenetla, sp. n. 



Metaphya elongata^ sp. n. 



Of the remaining 14 sjiecies, three are both common and 

 peculiar to New Caledonia (with the Loyalty Islands) and 

 the New Hebrides, namely, Agriocnemis eocsvdans, Selys, 

 Hemicordulia Jidelis, McLach., and Rhyothemis phyllis 

 apicalis, Kirby. 



The presence of Synthcmini })rovides a link with the
