66 On Odunata from New Caledonia. 



Legs black, with pale areas at base. 



Abdomen somewhat crushed aud distorted beyond seg- 

 ment 4; segments 1 aud 2 inflated ; 3 sharply constricted ; 

 4 and 5 enlarged and cylindrical ; 6 nnd 7 apparently 

 compressed laterally ; 8, 9, and 10 rather broad : metallic 

 black, without any pale markings, beyond a moderately 

 broad brovv)iish-yellow ring at the junction of segments 2 

 and 3. Anal appendages cylindrical, black. Gonapophyses 

 of segment 8 metallic black, not quite reaching the end of 

 the abdomen, rounded at apex, and convex ventrally ; the 

 two apical plates fused together into a single piece, weakly 

 cariuated mid-ventral ly. 



Subfamily Libellvlin^. 



Orthetrum caledonicum, Brauer. 



I ?, Plaine des Lacs, 24.ii. 14 (No. 346) ; 1 J, 2?, 

 JkU.Mou, 9. iii. 14 (465-467); 1 ? , Mt. Mou, lO.iii. 14 (487). 



The single male is olive-brown, like the females, it not 

 yet having acquired the pale blue pruinosity proper to the 



Diplacodes heematodes, Burm. 



2 c? , Mt. Canala, 12 & 14. vi. 14. 



The individual of later date has an extraordinary amount 

 of saffron suffusion in the wings, aud especially in the hind 

 pair, M here the coloured area extends beyond the anal loop 

 posteriorly, and touches the nodus anteriorly. In the fore 

 wings the sufl'usion ceases at about the level of the triangle. 



Diplacodes hipunctaia, Brauer.

 Lacs, 18. ii. 14 (No. 265). 



These specimens are remarkable for the amount of saffron 

 suffusion at the base of the wings, the colour reaching 

 outwards to about the level of the first anteuodal in both 

 pairs of wings. They evidently corresjjond with the two 

 feniales from the same island mentioned by Eis (Coll. Selys, 

 Libell. p. 472, 1911), and also with the females from New 

 Zealand to whicli McLachlan applied the varietal name 

 novce-zealandice (Ent. Mo. Mag. xxx. p. 271, 1894). The 

 species itself was originally described from Tahiti and New 

 Caledonia, and it would be interesting to know how far the 

 material before us agrees with Brauer's types.
