NOTES ON A SMALL COLLECTION OF HYMENOP 

 TERA FROM NARRABRI, N.S.W. 



By Walter W. Froggatt. 



I beg to offer the following brief notes, bearing chiefly on the 

 subject of geographical range, on a small but very interesting 

 collection of bees and wasps obtained in the neighbourhood of 

 Narrabri, N.S.W., by Mr. C. T. Musson, F.L.S, and forming 

 part of the general collection exhibited by him at the meeting of 

 this Society in December last. As far as it goes it is a typical 

 collection of Australian hymenoptera ; no species of Formicidce or 

 Mutillidce are represented in it, and Mr. Musson, to whom I am 

 indebted for the specimens, tells me that he only took such wasps 

 and bees as thrust themselves under his notice while collecting 

 land molluscs. As little has yet been done in systematically 

 collecting hymenoptera in this part of New South Wales, I have 

 no doubt, judging from the specimens now before me, that it 

 would prove a rich field to anyone devoting his time to this 

 group. 



Altogether, twenty-four species are contained in Mr. Musson's 

 collection ; but several of them are not in sufficiently good 

 condition for determination. 



1. Gen. et sp. incert. (Fam. Ichneumonidce, subfam. Oryptmse). 

 This species also occurs at Adelaide, S.A., in Victoria, and at 



Sydney, where it is plentiful, and is parasitic on the larva of 

 a common garden moth. 



2. Gasteruption sp. (Fam. Evannidw). 



A species which also occurs about Sydney. 



3. Chrysis sp. (Fam. Chrysididce). 



A species which has a wide range from Sydney northwards. 

 Several species are parasitic in the clay nests of Alastor, and 

 other genera of Eumenidte.
