BRITISH ODONATA IN 1913. 77 
R. South from larve of Peronea hastiana, October 18th, 1904, 
and October 21st, 1904, host from St. Anne’s, Lancashire. 
M. vexator (Hal.).—Is easily known by the size of the 
stigma, which is as large or even larger than the first cubital 
cell, with a considerable pale spot at the inner angle. We are 
indebted to Morley for redescribing this species,* from speci- 
mens bred by Keys at Plymouth out of a fungus, together with 
the clavicorn beetle Diphyllus lunatus (Fab.). Halliday described 
the female from a single insect, while Marshall, who described 
its supposititious male, had only a dilapidated specimen before 
him. In Morley’s insects the antenne of the male are 26-jointed, 
of the female 24, and the recurrent nervure is rejected. 
M., atrator (Curtis).—In August, 1913, C. W. Colthrup sent 
me from Eastbourne two females which he had captured with 
three specimens of the hyperparasite Hemiteles areator. The 
insects were caught while running about on furniture which was 
infested with the moth Tinea biselliella, and were evidently 
searching for the larve of the lepidopteron. Morley has a 
female which was also taken indoors. I believe that no specified 
host has before been cited for this species, and it appears to 
have been but rarely observed, which seems strange in the case 
of so beneficial an insect.

BRITS ODONATA IN, i19t3: 
By W. J. Lucas, B.A., F.E.S. 
(PuateE II.) 
AutHoueH the spring was an early one, I did not meet with 
a dragonfly till May 18th, when Pyrrhosoma nymphula and 
Tibellula quadrimaculata, the latter in teneral condition, were 
taken at the Black Pond, near Oxshott, in Surrey; no other 
species was seen—not even Hnallagma cyathigerum. On May 
25th the same locality was again visited, when a male and a 
female of Cordulia enea were taken, and E. cyathigerum was on 
the wing, as well as P. nymphula and L. quadrimaculata; but, on 
the whole, dragonflies were not very evident in a locality where 
they are usually so plentiful by this date. 
On June Ist a visit was paid to Frensham Ponds and the 
swampy ground near them, in the south-west corner of Surrey ; 
but the weather was dull. However, H. cyathigerum was found 
to be numerous. There were also a few J. elegans, and a female 
Agrion puella was taken. One or two teneral examples of
