The species is also related to Lasioptila ansorgei Kirby 

 (=Saturnia Tcuntzei Dewitz), which 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.

TROTONOTTTS, 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 stalked 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, with expansive lateral 

 tufts ; the legs very hairy ; middle and hind tibiae with strong 

 pointed terminal spurs, the hind tibiae also with a second 

 subterminal pair of spurs. Type T. bettoni.

J . Primaries above coffee-brown, faintly glossed here and there 

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

 base of cell ; an irregularly undulated, partly interrupted, internally 

 blackish-edged yellow >f -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, 

 traversed by four parallel dentate-sinuate stripes of the ground- 

 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. 

 Thorax greyish chocolate, with the top of the head, two large 

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

 portion of the thorax between the patagia bright brick-red ;
