This is one of the most variable Cimicidae known to me. I have examined 

 43 individuals, and the variations are apparently distributed through the Islands, and the 

 intermediate forms between the extreme varieties seem quite sufficient for their inclusion 

 under one species. The two most dissimilar forms of pronotal structure are figured. 

 The length of the bug varies from 8:^ — 13^ mm., and the ground colour from a beautiful 

 deep metallic green above and reddish below, to dull yellowish-brown above and pale dirty 

 fuscous below, or on the other hand, deep brown, almost black, above and below. The 

 extreme posterior part (the so-called "apex" of authors) of the scutellum is usually pale 

 flavous, but sometimes unicolorous with the general scutellar tfround colour. 



Hab. " Extremely abundant on forest trees, especially A/ciiriics, at almost all 

 elevations exceeding 1000 ft." (Blackburn). Hawaii, above Hilo, iSoo ft. (December); 

 Kona, 2000 — 4000 ft. (June to August and November). — Molokai Mountains, 3000 to 

 3500 ft. (July). — Maui, Haleakala, 5000 ft. (March, April, October). — Lanai, Mt. Koele 

 (February), Perkins. — Oahu, Burmeister and Stal, Kaala Mts., on fern, 2000 ft. (March, 

 April, August), Perkins ; Honolulu, Stal, 2000 ft. (April and October) ; Waianae Mts.,
