British Species of Caddis-flies. 35 
pterostigma, are almost wanting; fenestrated spot rhombic, large ; 
anastomosal space large; veins fuscous, the anastomosis very , 
dark. Posterior wings hyaline, the apex yellowish, no black 
beard on the first apical sector. Legs testaceous, with black 
spines. Abdomen greyish-fuscous above, somewhat greenish be- 
neath, the incisions of the segments paler. In the male the upper 
margin of the last abdominal segment is rather produced in the 
middle, and usually scabrous and black; app. sup. not large, 
somewhat triangular and obtusely pointed, testaceous, the margins 
fuscous, the lower edge toothed; app. intermed. broad, flat, tri- 
angular, blackish; app. inf. short and rounded, testaceous, fringed 
with long hairs. In the female there is a broad triangular plate 
proceeding from the upper margin of the last segment; the supe- 
rior valves are conical and hairy, testaceous. 
Expanse of fore-wings 14—15 lines. 
This insect has been bred by Mr. Parfitt. The case was com- 
posed of vegetable matters, shells and stones mixed heterogene- 
ously, often with a larger stone at one end; probably it is not 
to be separated from some forms of the case of L..flavicornis. 
A common and generally-distributed species in summer and 
autumn, varying much in the number and intensity of the brown 
markings. 
Mr. Parfitt has reared a Dipterous parasite (Hydrotachina lim- 
nephilt, Walker, MSS.) from the larvee of LZ. marmoratus.
