QQ On Odonata from New Caledonia. 



Legs black, with pale areas at base. 



Abdonieu somewhat crushed and distorted beyond seg- 

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

 4 and 5 enlarged and cylindrical ; 6 and 7 apparently 

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

 black, without any pale markings, beyond a moderately 

 bri;ad brownish-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-ventrally. 



Subfamily Libellitlinje. 



Orthetrum caledojiicum, Brauer. 



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

 i\it. Mou, 9. iii. 14 (465-467); 1 ? , Jdt. Mou, 10. iii. 14 (487). 



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

 yet having acquired the pale blue pruinosity proper to the 

 adult stage of its sex. 



Diplacodes hamatodes, Burm. 



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



The individual of later date has an extraordinary amount 

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

 pair, where the coloured area exteiHls beyond the anal loop 

 ])osteriorly, and touches the nodus anteriorly. In the fore 

 wings the sufiusion ceases at about the level of the triangle. 



Diplacodes lipunctata, Brauer. 



2 c? , Noumea, 24. i. 14 (Nos. 104, 105) ; 1 c? , Plaine des 

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



These specimens are remarkable for the amount of saffron 

 sufiusion at the base of the wings, the colour reaching 

 outwards to about the level of the first autenodal in both 

 pairs of wings. They evidently correspond with the two 

 females from the same island mentioned by lUs (Coll. Selys, 

 Libell. p. 472, 1911), and also with the iemales fiom Mew 

 Zealand to which McLachlan applied the varietal name 

 novca-zealandke (Ent. Mo. JNJag. xxx. p. 271, 1894). The 

 species itself was originally described from Tahiti and New 

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

 material before us agrees with Braucr's types.
