84 INSECTS OF SAMOA. ■ 



dark brown suffusions occupying costal half to apex ; a large scaletuft mixed 

 blackish above dorsum towards middle, and another above tornus ; a sinuate 

 silvery line crossing wing towards apex, and another round apical edge, terminal 

 area between these light ochreous with two blackish dashes : cilia on costa dark 

 fuscous with pale ochreous subbasal line, on termen whitish-ochreous with 

 tips fuscous. Hindwings rather dark grey ; cilia grey, tinged ochreous towards 

 base. 



Upolu, Malololelei, 2,000 feet, April ; 1 ex. 



40. Stoeberhinus testacea Butl. 



Upolu, Apia, Vailima ; Savai'i, Tuasivi ; Tutuila (Bishop Museum) ; April 

 to July, November ; 11 ex. in all. Doubtless common generally ; occurs also 

 in Fiji, New Hebrides, Hawaii, Marquesas, Rapa, and apparently throughout 

 the Pacific islands, but not known elsewhere, therefore indigenous in the region 

 and spread through it by man. Larva on dead grass, probably also on other 

 dry vegetable refuse. 



Agonoxenidae 



41. Agonoxena argaula Meyr. 



Upolu, Apia, September (Swezey) ; 1 ex. (Bishop Museum). Described 

 from Fiji (Exot. Micr. ii, 472), and also seen from the Ellice Islands ; the larva 

 feeds on leaves of coconut, and the species is doubtless transported by man. 

 Apparently the males are normally without the white streaks on the forewings, 

 though the females possess them. 



COSMOPTERYGIDAE 



42. Cosmopteryx mimetis Meyr. 



Upolu, Malololelei, 2,000 feet, Apia, January, April, May, September ; 

 6 ex. Also 2 in Bishop Museum (Swezey). Occurs also in Fiji, New Guinea, 

 Eastern Australia, Borneo, Tonkin, India, Egypt, Seychelles, Mauritius, 

 Rodriguez, Bermuda, and South America. Larva mining in leaves of Cyperus 

 rotundus, a very widely distributed plant, but the insect is probably artificially 

 introduced. There are, however, endemic species of Cosmopteryx in Fiji and 

 Rapa, and most likely in Samoa also.
