13 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.
