NOTES ON BUITISH TRICHOPTERA. O 



our fauna was captured by Mr. B. Cooke at Bowdon, 

 Cheshire, in 1866 and 1867, and I have also an example 

 i::iven to me by Mr. PifFard, and probably taken in the Lake 

 District. It is of small size for the section {ChcBtotaulius) 

 to which it belongs; scarcely exceeding L. (GoniotauUus) 

 vittatus. Yet the males have the '* beard " on the under- 

 side of the first apical sector of the posterior wings more 

 strongly developed than in any other species of the section. 

 It is a common continental insect, and the appendices are 

 i-ecognizably figured by Brauer in his *' Neuroptera Aus- 

 triaca," fig. 82. See also Aug. Meyer (Der Phryganiden 

 Westphaliens), in the ^* Stettiner Entomologische Zeitung" 

 for 1867, p. 161, for description of the larva and case ; and 

 (p. 153) for notes on the coupling of a male of L. striola 

 with a female of Anaholia nervosa. A singular, partly 

 ^rynandromorphous, example has been taken by Mr. Cooke, 

 In this specimen the abdomen is wholly female in structure, 

 but all the other parts of the body present characters of 

 both sexes. Thus the right-hand maxillary palpus is 

 3-jointed, the left 5-jointed; the right antenna is much 

 stronger than the left, especially in the basal joint ; the right- 

 hand anterior wing is differently marked to the left, and the 

 first apical sector of the right posterior wing shows beneath 

 the strongly developed " beard," which is wanting on the 

 left-hand wing. 



L. ignavus, Ha gen. A $ was taken by Mr. B. Cooke, 

 at Bowdon, Cheshire, in 1866. 



L. sparsiiSj Curtis. This species is almost endlessly 

 variable. A $ , taken at Scarborough, in 1866, shows no 

 trace of dark irrorations, and is almost of the uniform red- 

 dish-fuscous tint of Anaholia nervosa. 



Anaholia ccenosa, Curtis. I have seen a $ from Mr. B, 

 Cooke's collection; locality uncertain..
