518 LIEUT.-COL. J. M. FAWCETT ON THE 
Subfamily QUADRIFIN&. 
29. PoLypEsMA GLAUCcINANS (Guen.). (Plate XLIX. fig. 22, larva; fig. 23, pupa 
in web.) 
Larva. Ground-colour bright grass-green, with a broad white dorsal line from head 
to 12th somite, which bears on its centre a narrow pale blue dorsal line ; an interrupted 
white lunular lateral line, bordered with black superiorly. Head, thoracic legs, and 
claspers green; the first pair of abdominal claspers aborted; the 12th somite tapering 
to a point above the anal claspers. 
Feeds on wattle (Elephantorrhiza burchellii). 
Pupa pale brown, formed in a cocoon among the stems of the food-plant. 
Imago very common in Maritzburg in March. 
30. TanropyGa syLyiNa (Stoll). (Plate XLIX. figs. 10, 11, larva; fig. 12, pupa in 
cocoon.) 
Larva (early moults). Ground-colour buff; on each somite, except Ist and 11th, a 
broad very dark crimson transverse band; on Ist and 11th somites he band is pale 
ferruginous and bears some small black spots. In the final moult the above-mentioned 
bands become deep velvety black, with the exception of those on the Ist and 11th 
somites, which remain the same, the ground-colour becoming pale greenish. Head, 
legs, and claspers pale ferruginous. 
Feeds on Ornithogalwm eckloni (Sch.), a species of lily common in swampy places. 
When full-fed the larva burrows underground and constructs a chamber for the pupa, 
which is surrounded by a strong hard envelope, of a consistency similar to cement, with 
a small hole at one end for the exit of the imago. 
Pupa deep red, with black antemedial and postmedial lines on the wing-covers. 
The period of pupation lasts about five weeks. 
The imago is not uncommon in Maritzburg in January and February. 
Family GEOMETRID &. 
31. BoaRMIA ACACIARIA (Boisduval). (Plate XLIX. fig. 24, larva.) 
Larva. Ground-colour pale reddish brown, inclined to olive-green subdorsally; a 
pair of dorsal processes with whitish centres on 5th somite, and a pair of dorsal white 
spots on 11th somite. Head, legs, and claspers reddish. 
Feeds on a small species of sunflower, which is a common plant in gardens at 
Maritzburg. 
The transformation to pupa is effected underground.
