120 Mr. R. M‘Lachlan’s Monograph of the 
branched, the forks widely divergent, the lower the longest. In 
the female the abdominal spaces are wanting, and there is not a 
vestige of the broad cover over the last segment; the lateral 
valves are rather large, dilated, and testaceous. 
Expanse of fore-wings 7% lines. 
This singular species seems to be rare. I have seen but 
few examples, and only one female. Mr. Parfitt finds it near 
Exeter ; and I have taken it in June by the River Mole near Box 
Hill, also at Ringwood in Hampshire, and possess it from Kings- 
ton-on-Thames and Killarney. ‘The curious abdominal spaces 
and the cover over the last seginent render the identification 
of the male easy. 
B. Upper branch of the ramus thyrifer in the anterior nings

Leptocerus bicolor, Steph. (*) Ill. p. 201, 25 (1836), not of 
Curtis; Hag. (*) Ent. Ann. 1860, p. 73, 67. 
Antenne whitish, unspotted. Palpi fuscous. Head and thorax 
thickly clothed with reddish-brown hairs. Anterior wings very 
pubescent, brownish-ochreous, slightly paler about the anasto- 
mosis ; an appearance of a faint blackish line round the apex, 
and the apical cilia towards the anal angle also blackish-grey ; 
the three transverse veins forming the anastomosis placed in an 
oblique line. (The pubescence must be removed before the neura- 
tion can be seen.) Posterior wings purplish-black. Legs grey- 
ish; anterior tibia with one distinct apical spur. Abdomen 
greyish (greenish when alive), with pale lateral lines. In the male 
the app. sup. are small, broad and rounded ; app. inf. coming to 
an obtuse point; (the parts are not prominent, and difficult to dis- 
criminate exactly). 
Expanse of fore-wings 6 lines. 
Widely distributed about small rivers and streams, especially in 
the south, but scarcely known in collections. Abundant in June 
and July at Haslemere, in Surrey ; also in Devonshire, the New 
Forest, near Darenth, North Wales, &c.
