British Species of Caddis-flies. 61 
Expanse of fore-wings 12 lines. 
The only known specimen is Stephens’ type, said to have been 
taken ‘in June, in the vicinity of the metropolis.” 
The short broad wings and the length of the first apical cell 
readily distinguish this species from its congeners. So far as I 
am aware there is not any closely-allied European species, but 
S. punctatissimus of Walker from North America is scarcely dis- 
tinguishable at first sight, and apparently differs only in the app. 
inf. being blunt and truncated at the tips. 
6. Stenophylax cingulatus, Stephens. (PI. XI. fig. 6, app.) 
Halesus cingulatus, Steph. (*) Ill. p. 209, 2 (1837); Stenophy- 
lax cingulatus, M‘Lach. Trans. Ent. Soc. ser. 3, i. 237. 
Antenne, head, palpi and mesothorax reddish-ochreous, the 
last darker at the sides. Anterior wings pale greyish-yellow, im- 
maculate, the extreme costal margin brownish. Posterior wings 
subhyaline, slightly yellowish at the tips. Legs ochreous, with 
black spines. Abdomen dark blackish-fuscous above, with broad 
ochreous rings at the divisions of the segments ; beneath wholly 
ochreous. In the male the upper margin of the last abdominal 
segment is nearly straight; app. sup. prominent, furcate, the 
outer fork the longest; app. intermed. short and triangular, 
black; app. inf. long, directed upwards, rather obtuse at the 
apex ; penis much exserted. 
Expanse of fore-wings 18 lines. 
A single specimen in Stephens’ Collection, said to have been 
taken in “ Devonshire in July.” 
I have some suspicion that this may be only an old faded ex- 
ample of one of the two succeeding species, in which the app. 
sup. are protruded more than ordinarily. The pale abdominal 
rings I do not see, however, in any other. 
Stenophylax testaceus of Pictet, described in Ent. Ann. 1859, 
p- 93, 34, and there given as synonymous with Halesus cingulatus 
of Stephens, has not yet been discovered in this country. 
7. Stenophylax stellatus, Curtis. 
(Pl. IV. fig. 4, neuration and palpi; Pl. XI. figs. 7, 8, app.) 
Limnephilus stellatus, Curt. (*) Phil. Mag. p. 125, 32 (1834) ; 
Halesus stellatus, Steph. (*) Ill. p. 210, 7; Stenophylax stel- 
latus, M‘Lach. Trans. Ent. Soc. ser. 3, 1. 238; Limnephilus 
latipennis, Curt. (*) Phil. Mag. p. 125, 31 (1834); Stenophy-
