204 THE ENTOMOLOGIST. 
tegmina subhyaline, talc-like, basal area somewhat darkly opaque 
to a little beyond basal cell, the costal membrane virescent, post- 
costal area black, basal veins of the second and third apical areas 
darkly infuscate ; wings subhyaline, their basal areas ochraceous ; face 
moderately globose, centrally more or less longitudinally sulcate, the 
transverse ridges well pronounced; rostrum reaching the inter- 
mediate coxe; opercula slightly overlapping at their bases, then 
inwardly concavely narrowing to their apices, which are subacute, 
and reach the anterior margin of the fourth abdominal segment. 
Long. excl. tegm., 3, 43 millim.; exp. tegm. 120 millim. 
Hab.—Philippine Islands ; Mindanao, Davao (C. F. Baker). 
This species is allied to C. acuta, Sign., from which it 
principally differs by the much shorter opercula, the apical 
areas of which are also more convex outwardly and more 
concave inwardly. 
Pauropsalta vernalis, sp. n. 
Head, pronotum and mesonotum virescent ; abdomen above and 
body beneath and legs virescent or ochraceous; between eyes a 
transverse black fascia enclosing the ocelli, which are carmine-red ; 
tegmina and wings hyaline; the venation and costal membrane, of 
the first virescent or ochraceous; wings with five apical areas; 
head centrally sulcate between the ocelli; pronotum centrally 
longitudinally sulcate for more than half way from anterior margin ; 
opercula in ¢ small, broad, and convex; anterior femora with three 
spines beneath; tegmina with the basal cell longer than broad, the 
upper vein to the lower ulnar area fused with the lower vein to the 
radial area for nearly the length of the basal cell. 
Long. excl. tegm. 12 millim.; exp. tegm. 32 millim.

BRITISH ODONATA IN 1915. 
By W. J. Lucas, B.A., F.E.S. 
In 1915 the first dragonflies met with were a specimen or 
two of Pyrrhosoma nymphula, Sulz.,on May 16th, resting in dull 
weather upon the vegetation at the Black Pond, near Oxshott, 
in Surrey. They had but recently emerged, one or two being 
still yellow in colour, or even not fully expanded after leaving 
the nymph-skin. On May 30th this species was again found 
at rest on the vegetation at the pond, and with it was //nallagma 
cyathigerwmn, Charp.; while during transitory gleams of sun- 
shine one or two larger dragonflies were seen—no doubt Libellula 
quadrimaculata, Linn. A male Anax imperator, Leach, was seen 
on the wing near Oxshott on June 12th. In dull weather, at
