IRISH ACULEATE HYMENOPTERA. 



BY H. K. GORK CUTHBKRT. 



In a note on Col. Yerbury's Kerry list of aculeate Hymen- 

 optera^ I find it stated that "a comparison of this list with 

 the recorded Irish species shows that no fewer than twelve 

 were previously unknown to occur in Ireland." Among the 

 twelve is Cradro iv-maculatus, recorded by P. E. Freke from 

 Courtown.* The specific name ge7iictilatus was given by 

 Shuckard to the speeies properly known now as the 

 iv-7naculahis of Dahlbom. The term " var. geniculatus^^ is 

 applied by modern authors to the dark form, recognised by 

 Freke in above reference. 



Another of Col. Yerbury's insects, Bombus jonellus^ was 

 recorded b}'' me^ from Rosscarbery as B. schrim shir anus, the 

 synonj^m for jo7ielhis most used in the British lists. This 

 species is also upon Freke's list. The other ten species as 

 such have been unrecorded. Most of them are very distinct 

 and conspicuous, but two or three are so closely allied to 

 common insects, from which they can only be separated by 

 obscure anatomical differences in the male sex, that it is 

 probable they have been assigned in error in our list to their 

 allied species. It may be useful to bring together here all the 

 additions to the Irish list of aculeate Hymenoptera since 1897.*

On July 27th last, I captured, in a gravel pit at I^ucan, two 

 examples of No7?iada furva, Panz., recorded by Haliday, but 

 not taken in Ireland since his time. 



The Irish list now contains 148 species in 32 genera.
