IT is gratifying to find that the collection of Dragonflies made by Mr. A. F. R. 

 Wollaston, small as it is, should contain two new species, both of them of unusual 

 interest. These, together with the remaining specimens, form a valuable addition to 

 the collections of the British Museum (Natural History), which are not at all rich in 

 Odonata from New Guinea. 



One of the Dragonflies, Teinohasis metallica Forst., was obtained at Base Camp, 

 sea-level, Setakwa River, Nov.-Dec. 1912, and a new Sijnthemis was met with on 

 the Utakwa River, 4000 to 6000 ft., Jan.-Feb. 1913. All the others were obtained 

 on the Utakwa Biver, 2500-3000 ft., in February, 1913. 



Detailed information concerning the known species represented in the present 

 collection will be found in some of Dr. F. Ris's recent writings, notably his magnificent 

 monograph of the Libellulinae, his paper on the Dragonflies of the Lorentz Expedition 

 ('Nova Guinea,' ix., Zoologie, pp. 471-512, 1913), and his paper on Aru- and Kei- 

 Island Odonata (Abhandl. Senckenberg. Naturf. Ges. xxxiv. pp. 503-536, 1913). 



The two new species, Synthemis xvollastoni and Oda risi, are the only additions 

 made herein to the known Odonata of New Guinea. Another apparently endemic 

 form is the typical Teinohasis metallica, but the five remaining species obtained by 

 Mr. Wollaston have a more extended distribution. 



Subfamily Agrioninae. 

 Teinobasis metallica Forst. 



1 c? . Base Camp, sea-level, Setakwa River, Nov.-Dec. 1912. 



Dr. Ris informs me that this specimen, which he has seen, is certainly identical 

 with the insect so named by him in the two f'aunistic papers cited above, and probably 

 identical also with that referred to in Forster's original description.
