1924. Stelfox — Irish Hymenoptera Actilcata. 21 



A. afzeliella K. — Freke's record from Killiney is probably erroneous. I 

 have seen no Irish specimens of this species, and those so labelled 

 have all proved to be /i. wilhella, which is common and widespread, 



ANTOPHORIDAE. 



Nomada obtusifrons Nyl. — On a dull day — 23rd July, 1922 — I captured 

 a male and a female on the same flower of an Ox-eye Daisy near the 

 quarry on the west side of Glenasmole, at 900 ft. alt. Probably 

 parasitic on Andrena coitana, w^hich I have taken in the same place 

 in 1923. 



N. rufipes F. {= solidaginis Pz.). — Abundant in Glencree — and no doubt 

 parasitic on Andrena fuscipes — in September, 1922-23. Also in the 

 Deerpark, Powerscourt, though in this locality I have not seen the 

 Andrena. Like its host only previously recorded from S. Kerry, 

 but the Haliday specimens in the National Museum most probably 

 come from Co. Down. 



N. hillana K. {^ochrostoma K.). — Very abundant in the Rush district 

 in June, 1923, and much less common in the vicinity of Dublin. 

 At Rush obviously parasitic on Andrena wilkella. 



N. leucophthalma K. (= borealis Zett.). — Frequent in upper Glenasmole, 

 where its hosts Andrena apicaia and A. clarkella were taken in April, 

 1923. 



N. fabriciana L. — In Glenasmole, a female, on 20th May, 1922 ; another 

 on 5th May, 1923 ; and a male on 2nd April, 1923. This species 

 is a well-known parasite of Andrena gwynana, but the dates upon 

 which the two males were captured are rather late for the first brood 

 of that species, which was out in Glenasmole in the first week of 

 April, 1923, and much too early for the second brood. The specimen 

 recorded by Mr. Morley from Clare Island was wrongly named : it 

 is N. obtusifrons. 



Melecta armata Pz. — There is a male specimen of this species' in the 

 National Museum from the Trinity College collection. This has a 

 green-headed pin, supposed to indicate its Irish origin. No doubt 

 it is originally from the Tardy collection and if truly Irish it was 

 probably taken in Co. Wicklow. In Haliday's MS. list, under the 

 name M. punctata, it is recorded as Irish on the authority of Tardy. 

 It is, of course, the well-known parasite of Antophora pilipes. 



Antophora pilipes F. (= retusa K. and Haliday MS.). — In the National 

 Museum are four supposed Irish specimens, two females from the 

 Haliday collection and a male and a female from the Trinity College 

 collection. One of the Haliday specimens bears a label in Haliday's 

 writing " Antophora retusa. 2. From Box 28 where the rest Irish." 



' This and Antophora pilipes are recorded on my authority and have 

 not been seen by Dr. R, C. L, Perkins,
