 wings 53 millim. 



c? , Yoi, 18th April, 1897 ; $ , Taru, from larva obtained 

 12th December, 1896, pupated 20th December, emerged 4th May, 

 1897. 



The species is also related to Lasioptila ansorgei Kirby 

 {=Saturnia kuntzei Dewitz), A^hich must be referred to Dr. Hol- 

 land's genus Goodia, Kirby's L. pomona is not congeneric with 

 the latter ; therefore if his generic name is retained it must take 

 L. pomona as type, instead of L. ansorgei. 



I have named this pretty little species after the learned author 

 of the genus, to whom all students of African Lepidoptera owe a 

 debt of gratitude for his admirable work. 



EUPTEROTIB^. 



Teotowotfs, gen. nov. 



Allied to Gangarides, but with the form and aspect of Eutricha 

 {Lasiocampidce) : the primaries not falcate, the radial of the 

 secondaries (vein 5) wanting, only indicated by a fold, which 

 disappears when damped with benzine ; the angles of the cell also 

 almost parallel ; veins 6 and 7 not stall^ed as in Gangarides ; the 

 neuration of the primaries is practically the same in the two genera ; 

 the palpi are narrower, less densely fringed, the antennae bipecti- 

 nated almost to the tips ; the abdomen much shorter and conical 

 rather than truncated at the anal extremity, witli expansive lateral 

 tufts ; the legs very hairy ; middle and hind tibife wnth strong 

 pointed termmal spurs, the hind tibiae also with a second 

 subterminal pair of spurs. Type T. hetfoni.

 with glaucous ; a rose-and-white tufted ochre-yeUow spot below

 blackish-edged yellow ^-shaped band across the basal third, also a 

 few scattered yellow spots near its inner edge; a small deep 

 ochreous reniform stigma ; a broad internally angulated and 

 undulated, externally irregular and sinuated discal yellow belt,

 colour and bordered outside by a blackish stripe ; an oblique 

 increasing slaty-blackish streak from apex, continuous with four 

 transverse patches of the same colour parallel to outer margin ; 

 fringe darker than the rest of the ground-colour and tipped with 

 blackish : secondaries pale ruddy-chestnut, shading into bone- 

 yellowish on basi-costal area ; fringe tipped with snow-white.

 subcoufluent spots on the middle of the collar, and the dorsal
