Clare Island Survey — Hymenoptera. £4 3 



in the following list about a hundred are now recorded for the first time from 

 the Irish area. The majority of these new records occur amongst the 

 Ichneumonidae. 



The aculeate groups, on the other hand, having been much more studied, 

 naturally yield the fewest novelties. In view of the interest taken in these 

 insects, it may be pointed out that six species from the Clare Island district 

 were not previously known to occur in this country. These are :— Gorytes 

 iv-fasciatus, Crabro albilabris, Sphecodes hyalinatus, Sphecodes ferruginatus, 

 Halictus Freygessneri ; the last-named species is represented in the collection 

 by a single injured example, and must be recorded with reserve.
