 The central and southern species constitute a much smaller group ; we may 

 perhaps refer to Adicella rcducta, and Wormaldia mediana. In so far as we 

 can judge by their known range, it seems likely that at least four of our 

 Irish Caddis-flies are south-western in Europe: namely, Sefodes argimtijmndii/o, 

 Tinodcs macnlicornis, Lypc fragilis, and Agapdus ddicatulus ; while Pohjccn- 

 tropus Kingi should probably also be referred here. The scarcity of purely 

 alpine, as opposed to northern and alpine, forms in Ireland is notable, a 

 scarcity which appears to hold good for these insects throughout the entire 

 Britannic area. The two species which would appear to possess such a 

 range are Drusus anmdatns, and AjMtania fiinhriata. 



The following is a sliort list of some Irish species that are interesting 

 on account either of their geographical distribution or of their general rarity. 

 More detailed notes on their range will be found in the systematic part of 

 this paper: —
