A black and nitidulous species, with the legs fulvous. Head buccate, 
of ¢ with the mouth, face and antennal orbits flavous; of 9 with the 
mouth and a facial fascia below the scrobes pale. Antennae basally 
flavescent beneath. Abdomen black and not broad; of @ often centrally 
badious, rarely testaceous ; first and base of second segment alutaceous. 
Legs pale, with the hind coxae basally infuscate. Wings with tegulae 
stramineous, stigma broad and pale piceous; radial nervure apically 
curved. Length, 34 mm. 
I have found this species by no means difficult to recognise, since it is 
the only one we have among those with no areolet and the recurrent 
nervures remote, that has the stigma broad, infuscate and distinctly 
rounded below, emitting the distinctly curved radial nervure from its exact 
centre. 
It is very common with us, though not recognised till 1898, when 
Bignell recorded it from Ivybridge in Devon in the middle of September; 
he has, however, given me unnamed specimens which he took in Septem- 
ber at Bickleigh as long ago as 1882; I also have examples from Bishops 
Teignton in Devon, Nunton in Wilts (Marshall), Shere (Capron), Alde- 
burgh in September and Bungay in June and October (Tuck). It is 
undoubtedly one of our commonest species, and my thirty specimens 
were all taken in June and September, as though there were two broods ; 
in the former month the ¢ is not uncommonly met with in company with 
that of S. /aricrs, though usually in more marshy situations, on grass and 
reeds; Ranworth Broad, Norfolk; Tuddenham Fen, Mildenhall, Eriswell, 
Covehithe Broad, Reydon Marshes, Brandon staunch ; and a small dark 
from beneath the leaves of a lime tree in my Monks’ Soham garden. 
It has not yet been bred.

A shining, black and finely punctate species with pale legs. Head sub- 
buccate and hardly constricted behind the eyes; frons subdeplanate and 
obsoletely punctate; face shining and normally protuberant; mouth and 
upper margin of Q face fulvescent, g also with whole face flavous. An- 
tennae longer than half body, basally testaceous beneath, 30—32-jointed 
with the basal flagellar joint cylindrical, longer than broad and the ¢ 
flagellum subserrate beneath. Metathoracic areae very distinct. Abdomen 
a little longer than head and thorax; basal segment not very broad, sub- 
elongate and aciculate, laterally impressed beyond its centre with carinae 
somewhat distinct; second longer than broad, aciculate towards its base, 
with distinct thyridii; venter flavous. Legs somewhat stout and fulvescent- 
flavous, with the hind coxae often nearly entirely black; @ with anterior 
coxae and trochanters paler. Wings with tegulae flavous; radial nervure 
apically nearly straight; stigma luteous and not broad with its lower margin 
not rounded. Length, 3—4 mm.
