19^4' Stelfox — IrisJi Hymcnoptcni Aculcaia. 17 



COLLETIDAE. 



Colletes picistigma Th. — lSh\ E. O'Mahony captured a female on the 

 coast near Raheny, Co. Dublin, in July, 1922. In 1923 it occurred 

 very plentifully to me at Portrane at the end of June and beginning 

 of July, where it was nesting all over the sandy slopes about the 

 Martello Tower, while in the latter month I also captured it along 

 the south cliffs at Howth. 



C. succincta L, {=glutinans Cuv.). — A male in Glenasmole on 1 8th August, 

 1923 and a male and a female in Glencree on 9th September, 1923, 

 are my only records for this species, which is probably not uncommon 

 in the heathery parts of Wicklow a.nd Dublin. 



C. montanus Mor. — I discovered a large colony of this species, towards 

 the end of June, 1922, nesting on the low cliffs (in clay) on the eastern 

 side of Carnsore Point, and within a few hundred yards of thiS; the 

 extreme S.E., corner of Ireland. The following day I saw several 

 males on the dunes at Rosslare. 



ANDRENIDAE. 



In the genus Sphecodes there are, T am afraid, more erroneous than correct 

 records for Ireland owing to the fact that the older generation had 

 neither the papers written by Dr. Perkins dealing with this difficult 

 genus, nor, what is still better. Dr. Perkins himself to assist them. 

 All the corrections mentioned below, as well as the new records, 

 are, of course, on Dr. Perkin's authority. 



Sphecodes monilieornis K. { = suhqnadratus Sm.). — I have taken females 

 of this in the Rocky Valley, 30th May, 1922 ; near Lusk and at the 

 Ford of Fine, nth June, 1923 ; and near Ben Head on the Meath 

 coast on i8th June, 1923. 



S. spinulosus v. Hag. — Erroneously recorded from Kilkenny* in Freke's 

 list. The specimen, a female, is S. riibicundus, not hitherto recorded 

 for Ireland.^ 



S. pellucldus Sm. {=pilifrons Th.). — The " Kilkenny" specimen referred 

 to by Freke is not this species but merely one of the very large form 

 of 5. divisus K. Although the host of this species — A ndrena sericea 

 {alhicrus) — is a common species in the Dublin district I have taken 

 no specimen of its parasite. 



S. divisus K. { = simiHs Westm.). — Frequent in Cos. Dublin and Wicklow. 



S. rufescens Fourc. {=ferruginatus Schk.). — The only Irish specimen I 

 have seen is a female captured by me in the field behind the hotel 

 at Newrath Bridge, Co. Wicklow, on 5th June, 1921. It is recorded 

 for Cos. Donegal West (Johnson) and Mayo West (Morley). 



^I would much like to see the "Kilkenny" records verified, as 

 amongst the insects given by the Rev. T. M. Gibson to the National 

 Museum were many from Sussex, and I fear that some of the latter may 

 have been subsequently labelled '" Kilkenny " by mistake. If not, then, 

 Kilkenny must provide some excellent collecting grounds for the aculeates.
