Clypeus brown; labrum dark brown; labium and mandibles paler 

 brown. Thorax: Prothorax narrow, shiny black. Meso- and 

 metathorax hairy, shining metallic black, with bronze reflections. 

 Abdomen short, subcylindrical; seen from above, almost the 

 same width from end to end; seen sideways, tapering gradually 

 from 3 to end. Colour dull black. Segment 10 carries a small 

 hairy projection between the appendages. Appendages 

 short, 07mm , wide apart, pointed, subcorneal, black (Plate xliv., 

 fig.l). 



Hob. — Kuranda, near Cairns, N.Q. A single female was cap- 

 tured by Mr. F. P. Dodd of Kuranda, in December, 1904, about 

 12 miles up the river Barron above that township. 



This unique specimen is closely related to B. bipartita from 

 Borneo. The latter has the wings less coloured with black. It 

 also comes somewhat near to JR. resplendens (£), from which it 

 may be at once distinguished by its greater size and by the black 

 colouration of the wings being continuous, whereas in resplendens 

 (£) it is broken by an oval hyaline spot 4-5 mm. long. It would 

 be interesting to obtain the male, which might be either a black 

 insect like the female, or a brilliantly coloured insect like 

 r'esnlendens(£). 



3. Crocothemis ERYTHRiEA Brulle. 



This species is very widely distributed, being found commonly 

 over the South of Europe, the Continent of Africa, Ceylon, and 

 the East Indies. A single pair was taken by me on Carrington 

 Marsh, near Atherton, N.Q., flying like 0. villosovittatum, around 

 the edges of the marsh, and often settling high upon the branches 

 of overhanging trees, with wings depressed. C. servilia Drury, 

 already recorded from Australia, is a larger insect, with wings 

 totally shaded with yellow. C. nigri/rons Kirby, is the only 

 other Australian species of the genus, and is blue, with black 

 head and thorax. 



4. Erythemis rupa Ramb. 



At first sight this insect is almost exactly like C. erythrcea. 

 There is a difference, however, in the neuration of the discoidal
