MICRO-LEPIDOPTERA. 



115 



scales, second joint with several lateral bristles, terminal joint slightly shorter 

 than second, pointed. Maxillary palpi rather long, several-] ointed, folded, 

 loosely scaled. Posterior tibiae smooth. Forewings lb furcate, 2 from angle, 

 3 approximated, 4 absent, 5 closely aj>proximated to 6 towards base, 6 and 7 

 stalked, 7 to costa, 8 somewhat approximated, 9 from angle, 10 from towards 

 angle, 11 from before middle. Hindwings f , lanceolate, cilia 2 ; 2 and 3 very 

 short, 4 absent, cell probably open between 2 and 5, 5 and 6 stalked, 6 to termen, 

 7 nearly connate with stalk. 



Quite abnormal, but possibly having some relation with Hestiaula, which, 

 however, is itself an entirely isolated form. 



129. Marmaroxena autochalca, n. sp. 



J 8 mm. Head shining dark purplish-bronze, face paler. Palpi whitish- 

 ochreous. Antennae dark grey. Thorax shining dark purple-bronze. Fore- 

 wings elongate, slightly dilated, costa gently arched, apex pointed, denexed, 

 termen very obliquely rounded ; shining dark purple-bronze ; the deflection 

 of apex produces a slight transverse brighter purple depression on costal half at 

 f , and another somewhat more marked beyond this lighter and tinged golden- 

 metallic towards costa : cilia dark grey, basal half blackish. Hindwings dark 

 purplish-bronzy-grey ; cilia purplish-grey. 



Upolu, Apia, May ; 1 ex. This species and Philocoristis catachalca, which, 

 though in no way related together, are both much modified in the same sense 

 from their normal facies, suggest imitation of a common model, perhaps a 

 metallic Hemipteron. 



130. Monopis monachella Hiibn. 



Upolu, Malololelei, 2,000 feet, February ; 1 ex. Occurs in Europe, Africa, 

 India, Ceylon, Sumatra, Formosa, Hawaii, and North America, artificially 

 introduced ; the larva feeds on dry skins, wool, and refuse. 



131. Monopis semivittata, n. sp. 



7 mm. Head whitish-ochreous, some fuscous Lairs on each side of fore- 

 head. Palpi whitish, terminal joint fuscous except towards apex. Forewings 8 

 and 9 stalked ; purplish-grey suffusedly irrorated blackish, two or three scattered
