ODONATA COLLECTED BY MR. J. D. BRADLEY ON GUADALCANAL ISLAND, 1953-54 By D. E. KIMMINS THE Odonata dealt with in this paper were collected by Mr. Bradley during stops on Guadalcanal on his way to and from Rennell Island. The Odonata of Guadal-canal are better known than the Trichoptera, and Lieftinck (1949) lists twenty-eight species. Mr. Bradley collected fourteen species of which six were additions to those listed by Lieftinck, these six including at least three new species and two new genera. There is a high proportion of species endemic to the Solomon Islands, no fewer than fourteen of the total of thirty-four being restricted to the Solomons. The types of the new species are in the British Museum (Natural History). ODONATA ZYGOPTERA Family LIBELLAGINIDAE Rhinocypha liberata Lieftinck Tapenanje, 10-23. xii. 1953, 22 <$, n $. The present examples differ slightly from Lieftinck's description and from Solomon Islands specimens (ex McLachlan collection), determined by myself as R. liberata, but I do not consider the differences to justify the erection of a new subspecies. The specimens are a little larger and the brown apices of the wings appear to be a little more extensive. In many examples the infuscation of the fore wing extends almost completely to the apical margin, even in teneral specimens, and in none is the paler space distad of the pterostigma as distinct as in Lieftinck's description. In teneral examples the apical half of the pterostigma is pale cream. ?. Humeral stripe a little less reduced than in $. Abdomen black, with a fine, yellowish, median carina. Sides of the segments marked with deep yellow : segment i, one large spot ; segments 2-7 with two spots, the anterior the larger, the spots becoming progressively reduced towards apex of abdomen ; segment 8 with only one basal spot. Membrane of wings pale yellowish, hind wing with a brownish apical patch, varying in size and intensity in individuals up to nearly the apical third, paler along the costal margin. Extreme apex of wing narrowly opaque whitish. Fore wing sometimes with very indistinct brownish shading in apical third but not reaching extreme apex, which is also very narrowly opaque whitish. Pterostigma dark brown, apical half deep cream to reddish brown. ENTOM. 5, 8. 20
