Lepidoptcra from the South Pacific. 217 



Zealand specimens these veins are very shortly stalked ; 

 in all other respects the specimens agree exactly, and I 

 believe that these differences are merely sexual or per- 

 haps individual only. 



Mesopempta, n. g. 

 Forehead rounded, vertical ; ocelli absent (?) ; tongue well 

 developed. Antennas three-fourths of fore wings, in male (?). 

 Labial palpi moderate, arched, rather ascending, second joint with 

 dense projecting scales beneath, terminal joint very short, cylin- 

 drical. Maxillary palpi absent. Posterior tibise in female with 

 outer spurs half inner. Fore wings with veins 8 and 9 stalked, 

 10 very closely approximated to 9 towards base. Hind wings as 

 broad as fore wings ; vein 4 rising from lower angle of cell, 5 from 

 middle of transverse vein, parallel to 4 and 6, G from upper angle, 

 7 from before angle, 8 anastomosing with 7 from middle of cell to 

 considerably beyond cell. 



Differs from Siculodes by the peculiar position of vein 

 5 of the hind wings, and the anastomosing of veins 

 7 and 8. 



42. Mesopempta heliopsamma, n. s. 



$ , IG mm. Head, palpi, and thorax light reddish ochreous ; 

 antennae, abdomen, and legs whitish ochreous ; antenna; obscurely 

 annulated with darker ; tarsi darker, with pale rings at apex of 

 joints. Fore wings triangular, costa almost straight, apex tolerably 

 rectangular, hind margin obliquely rounded, slightly siiauate 

 beneath apex ; reddish ochreous, with numerous irregular tolerably 

 straight pale transverse strigulae ; costa with some pairs of whitish 

 dots, and partially finely dotted with dark fuscoiis ; hind margin 

 beneath apex obscurely dark fuscous ; cilia reddish ochreous, tips 

 paler. Hind wings with colour, strigultc, and cilia as in fore wings. 



Port Moresby, New Guinea (Mathew) ; one specimen. 



MUSOTIMIDiE. 

 The modified definition of this family should be: Fore wings 

 with vein 10 absent, 8 and 9 stalked, sometimes also 7 out of 8. 

 Hind wings with vein G from upper angle of cell, 7 from upper 

 margin of cell before angle (or rarely out of 6), anastomosing with 

 8. Abdomen in male with uncus strongly developed, complex. 



The subjoined new genus is so closely allied to 

 Trichoplijisctis in nearly all structural characters, espe- 

 cially in the family character of the absence of vein 10
