SOUTHEND LEPIDOPTERA IN 1947 71
are marked with black rather more heavily than in most species
of the genus, segments three to seven having spear-headed black
markings of increasing size, seven being almost entirely black.
The eighth segment is largely blue with a pair of narrow black
marks at the side of the posterior edge, segment nine blue with
a black ring which broadens at the edges and a narrow blue ring
at the posterior edge, segment ten black with narrow blue edging.
The anal appendages are very small, but the upper pair are
considerably longer than the lower. Wings hyaline with the
pterostigma considerably longer than the cell immediately
beneath, legs black with lighter bluish markings.
The female has the eyes and the markings on the thorax
bluish green, the abdomen is cerulean blue and more heavily
marked with black than in the male. In flight the female appears
much more blue than most other species of the genus and in
this respect resembles a small specimen of C. pulchellum Van
der Lind. C. scitulum is considerably smaller than the other
British species, with the exception of C. mercuriale Charp., the
average size being:—male: wing expanse 36 mm., body length
29 mm.; female: wing expanse 37 mm., body length 28 mm.
Abroad the species has a range extending from France,
Belgium and Spain over the whole Mediterranean region, which
seems to be its headquarters, and as far east as Persia. One
other species closely resembles scitulum, this is Coenagrion
caerulescens Fons., which is restricted to southern Europe.
I should like to thank Miss C. E. Longfield for her help and
for determining the species. Further details and figures may be
found in The Entomologist, vol. 80, pp. 54-55, also p. 272, and
The London Naturalist, No. 26, p. 80.
