VII.—On a New Genus and Species of Odonata 
from Sarawak. — By Dr. F. F. Laidlaw. 
Sub-family CORDULIINAE. 
J 
Group Cordulina. 
Metaphya, gen. nov. 
Anal loop elongate, with longitudinal bisector; apex 
blunt, scarcely widened, not spurred. Triangle of hind¬ 
wing recessed to level of arculus. Discoiclal triangles 
of all four wings, and internal triangles of fore-wings 
uncrossed. Sectors of arculus united at their origin. 
Short sector and upper sector of triangle (M 4 Cu x ) 
slightly divergent in fore-wing. Only one cubito-anal 
cross nerve in fore and hind-wings. Small species, 
abdomen markedly constricted after 2. Spindle-shaped 
in the male for its terminal quarter. Appendages small 
filiform.

The classification of the sub-family Corduliinae has 
recently been discussed by Williamson (1908) Needham 
(1908 a) and Tillyard (1910). These writers are agreed on 
a subdivision of the sub-family into groups characterized 
by the anal area. In the one group, Corduliinae s. sir. 
of Williamson and Needham, Cordulina of Tillyard, the 
anal loop is elongate with a longitudinal bisector as in 
most Libelluiinae. In the other group, Macromiinae of 
Williamson and Needham, regarded as including two 
groups of equal systemic importance by Tillyard, viz., 
Macromina and Synthemina, the anal area consists of a 
compact set of cells. Metaphya then falls into the 
Cordulina group. In this group a number of genera, 
*Dr. Ris informs me in a letter that from a study of the venation 
as seen in the photograph, he is inclined to think it related to 
Syncordulia.
