XV.—Some Additions to the Dragonfly 
Fauna of Borneo. By F. F. Laxdlaw. 
CALOPTERYGINiE. 
1. Vestalis beryllcs , n. sp. 
One male, Retuh. 
Length of abdomen 70 mm., of hind wing 41 mm. 
A single row of cells between Cui and Cu 2 . In the front 
wing this row breaks up into several near the wing margin ; 
in the hind wing it remains single up to the marginal cell. 
The wings are slightly tinged with yellow. The body is 
entirely metallic green in colour, save for the under 
surface of the head which is black, as are the legs and 
anal appendages; whilst the under surface of the thorax 
is powdered with whitish bloom. The great relative length 
of the abdomen is more remarkable than is the case even 
in V. gracilis , Ramb., a species to which the present form 
bears a close resemblance. 
The upper anal appendages are long and rather stout; 
at first curved inward they then diverge, and finally 
approach each other again, resembling when seen from 
above two figures S3 inverted and facing each other. 
The lower pair are short, one-half the length of the upper 
pair, cylindrical, slender, and nearly straight. 
This very distinct new species is an interesting addition 
to the genus. 
The type is in the British Museum. 
2. Rhinocypha karschi , Kruger. 
R . karschi , Kruger, Stettin Entomol. Zeit. 1898, 
pp. 88-85 ; Laidlaw, Proc. Zool. Soc. London, 
1902, p. 90. 
Three males, Tatau. 
This interesting species has the stature and appearance 
of a Micromerus , but its venation is that of a Rhinocypha. 
It appears to be the only species of the genus which is
