very constant in the markings. Dr. Staudiuger says it is nearest to 

 C. selina female. Expanse, G8 mm. 



Hah. Venezuela. I take the liberty of dedicating this species 

 to Mr. F. Du Cane Godman, D.C.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. 

 Eather similar in form to Monethe molione (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 {Prosopis julijlora), gluebush (Mimosa), 

 and the hateful lantana {Lantana camara), 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 

 Malvaceae, 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 

 conveuient 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 BOO or 400 ft. lower.
