258 PROCEEDINGS OF THE 



SPECIMENS EXIHIBITED. 



Mr F. G. Binnie exhibited some additions to the Trichoptera of 

 the Clyde Valley, stating that for the collection he was indebted 

 to Mr E. J. Morton of Carluke, who had sent them to him to 

 be named. The specimens were all taken in that district during 

 the past season. The collection comprised over thirty species, 

 and illustrated very clearly what has yet to be done in the 

 investigation of this group, for on looking it over he found at 

 least five species which did not find a place in his list of 

 Trichoptera in the British Association Guide. Two of these 

 belong to the family Limnophilidae, two to the Sericostomatidae, 

 and the fifth to the Rhyacophilidae. The species are as follows : — 



LimnopJiilus griseus, L. This species he had obtained from the 

 Scotch firs at Eannoch, and in the Braemar district. M'Lachlan 

 states that it particularly aftects uncultivated districts with fir 

 forests. 



Halesus auricoUis, Pict. This species has been added to 

 the British list since the publication of the " Trichoptera 

 Britannica " ; and so far, it is known only from Scotland and the 

 north of England. M'Lachlan found it in countless myriads by 

 the river Wharf at Bolton Abbey, Yorkshire, The only specimen 

 in the present collection is a female. 



Sericostoma personatum, Spence. This species is remarkable for 

 the extraordinary development of the maxillary palpi of the male, 

 which form a mask over the face, whence its trivial name. It 

 is the only species found in our islands, occurring in England, 

 Scotland, and Ireland. 



Goera iJilosa, Fab. This is the first example Mr Binnie had 

 seen from the Clyde district; but he had captured it during 

 the present season at Aberlady. It is the flavipes of Curtis. 



Rhyacophila ohUteraia, M'L. Its ally dorsalis, may be considered 

 one of the commonest and most generally distributed species of 

 the group in our district, occurring by every burn and rapid stream. 

 The present species is distinguished in the male by the short broad 

 lobe of the upper margin of the last abdominal segment, and the 

 character of the terminal joint of the inferior appendices. The 

 only localities given for it by M'Lachlan in his " Trichoptera 

 Britannica" are North Wales, North Devon, Stafi'ordshire, and 

 Scarborough, being common in the first-named district along all 

 the mountain torrents at considerable elevations.
