DESCRIPTIONS OF TWO NEW SPECIES OF EUPLCEA FROM THi; 

 SOUTH SEA ISLANDS. 



BT HAMILTON H. DRUCE, F.E.S. 



EUPLCEA (JS'iPAEA) WaLKERI, Sp. 11. 

 $ . Allied to Nipara intermedia, Moore, from -which it differs by the much 

 larger discal spots, notably the lower one, which is about twice the size of that of 

 N. intermedia, and the apical band of spots is large and distinct. On the hind-wing 

 the submarginal row of oval spots is rather narrower, but much more clearly defined, 

 and closer to the marginal row, which is also very distinct. Under-side, as abore. 

 but with a small blueish-white spot in the cell of the fore-wing near the end, thrt>e 

 more just beyond, and eight on the central area of the hind-wing, as in N. helcifa, 

 Boisd., and N. Eschscholtzii, Feld. Expanse, 85 in. 



Hah. : Tahiti, Society Islands. Mus. Druce. 



I have named this form after Mr. J. J. Walker, E.jS"., who obtained 

 it and the following species. 



EuPL(EA (Nipara) unicolor, sp. n. 



$ . Uniform dark brown, without any spots or markings. Under-side nearest 

 to N. indistincta, Moore, but the spots on the fore-wing much smaller, and on the 

 hind-wing the marginal row has entirely disappeared, and the submarginal is 

 scarcely distinguishable. 



? . Upper-side, as ^ , but a lighter shade of brown, and with a white spot on 

 the costa. Underside, as $ . Expanse, ^ , 3^ in. ; 9,85 in. 



Hab. : Aitutaki, Cook Islands. Mus. Druce. 

 We possess a ^ specimen, which I take to be a variety of this 

 species, which has a small white spot on the costa at the end of the 

 cell, this being the only marking on both surfaces of the wings, with 

 the exception of several small bluish spots just beyond the cell on 

 the iinder-surface of hind-wing, whilst the apex of fore-wing, and the 

 whole area of the hind-wing, is of a pinkish tinge beneath. 

 London : October, 1890. 



GREAT FLIGHT OF CULEX, TIPULA, AND TETRAMORIUM IN 

 NEW ZEALAND. 



BY W. W. SMITH. 



In the " Field," of December 7th, 1889, I called attention to the 

 occurrence in New Zealand of some abnormal swarms of Culex arqy. 

 ropus, Walk., and made some remarks on great flights of other species, 

 that I had observed in previous years. Throughout the past season, 

 which has been truly an entomological year in New Zealand, I have 

 learned of other great swarms in different parts of the country, and 

 observed one myself, which I now propose to record.
