The same author (Eiit. Ann. 1865, pp. 29-36) publishes a 
catalogue of the British species of Trichoptera, in anticipation of 
a manual of these insects, which he announces as in a forward 
state of preparation. This catalogue, which gives the synonyms 
with the authors^ names, but without references to works, includes 
123 species, five of which are marked as undescrihed. Two new 
genera are indicated : namely, Ti'icena, allied to Mystaddes, 
species T. bicolor (Curt.) and T. conspersa (Ramh.) ; and Wor- 
maldia, allied to Philopotamus, species W. occipitalis (Piet.) and 
W. subniger (M^Lachl.).
