318 LIEUT. -COL. J. M. FAWCETT ON THE 



Subfamily Quadrifin^e. 



29. Polydesma glaucinans (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. TLeniopyga sylvina (Stoll). (Plate XLIX. figs. 10, 11, larva; fig. 12, pupa in 

 cocoon.) 



Larva (early moults). Ground-colour buff; on each somite, except 1st and 11th, a 

 broad very dark crimson transverse band; on 1st 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 1st and 11th 

 somites, which remain the same, the ground-colour becoming pale greenish. Head, 

 legs, and claspers pale ferruginous. 



Feeds on Ornithogalum 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 GEOMETRIDiE. 



31. Boaemia acactaria (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.
