174 THE ENTOMOLOGIST. very constant in the markings. Dr. Staudinger says it is nearest to C. selina female. Expanse, 68 mm. Hah. Venezuela. I take the liberty of dedicating this species to Mr. F. Du Cane Godman, D.G.L., F.R.S., &c., through whose generosity our National Collection is being greatly extended, en-larged, and considerably enriched. MONETHE JOHNSTONI, Sp. n. (PI. VII. fig. 2). Male, Wings orange ; apex blunt ; external margin black, irre-gular, widest at the apex. Hind wings : outer margin black, with a narrow metallic green hair-line near the outer edge. Under side similar, but paler, and without the green hair-line. Palpi long. Rather similar in form to Monethe vwlione (Godman), but the apical spot is disconnected in that species. Expanse, 38 mm. Hah. British Guiana. I have the pleasure of naming this species after Sir Harry Johnston, K.C.B. SOME NEW OAHUAN (HAWAIIAN) HEMIPTERA. By G. W. Kirkaldy. The island of Oahu may be divided roughly into two parts, viz. the Forest Region, say, from 1500 ft. upwards, to which for the most part autochthonous insects are confined — and those, indeed, sparsely — and the Lowlands, where introduced plants flourish, and where autochthonous forms are the exception. Around the coast, during the greater part of the year, there is nothing but a dreary vista of algaroba {Prosopisju'lijlora), gluebush {Mimosa), and the hateful lantana {Lantana cainara), all of them destructive to clothing and temper. Some time, however, during the period which the people here are pleased to call " winter," but which would pass very well for summer in England— and, if I may judge from recent reports, would scarcely be distinguishable from the English summer of 1903 — sometimes varying much as to exact time and duration ; after the heavy rains of November, December, January, and even, as this year, February and March, a lowly investment of Malvacea3, especially Sida, Linne, and other similar plants, springs up, and with it certain insects found only at such times and in such situations around the Oahuan coast. The spot most convenient for dwellers in Honolulu is the well-known Leahi, or Diamond Head, an extinct crater some six miles from the city.* Inside the crater (near the top of the rim only, for lantana and mimosa now fill the sides and floor), on the sloping sides exte-* The highest point of Leahi is 762 ft. above sea-level, the floor of the crater being 800 or 400 ft. lower.
