66 MR. F. MOORE ON THE OPHIDERINZ OF THE INDIAN REGION. 
minute Geometriform larva was hatched ; it was very active, dropping itself by a silken 
thread when disturbed ; transparent, yellow and blackish in alternate belts, sparsely 
covered with hairs; fourteen legs (those on 6th segment wanting); head disproportion- 
ately large, holding the head up and also the two last segments. 
“On the 13th it changed to a shining, translucent green, the anterior and posterior 
segments very much more pale and yellow, 4" long; head now the smallest segment, 
dull pale testaceous, the rest of the segments a pale translucent yellow, which, how- 
ever, in segments 2 to 9 inclusive, look green—a light bright grass-green—the colour 
seeming to come from the inside; on the 4th, 5th, 6th, 7th, and 10th segments are pale 
brown lateral patches; every segment has apparently ten black tubercular spots, each 
carrying a hair; legs black. 
“On the 14th it changed to a velvety black, of the same form and attitude as before ; 
a vermillion spot on each side of the 5th and 6th segments, on the 5th each spot accom- 
panied by an anterior white speck ; white lateral markings on 10th and 11th segments. 
“ On the 17th it changed to a black, with rufous and white ocelli where the vermil- 
lion spots were in preceding stage, and several rufous and white specks. 
“On the 20th it changed to a most handsome variegated rufous and black, with 
innumerable lilac, white, and rufous scattered specks. 
“On the 25th it spun a leaf loosely across itself, on a bush above ground, and turned 
into pupa. 
“On October 8th the perfect insect (0. fullonica) emerged.” 
This insect has also been reared at Canara by Mr. S. N. Ward, from whose MS. is 
the following extract :—‘ Larva with sixteen feet, but the first pair of ventrals almost 
obsolete and retractile. Body cylindrical, smooth, and velvety to the touch, but with 
scattered minute hairs over all the body; 11th segment much thickened at the extre- 
mity, falling off abruptly behind, and surmounted by a red currant-like spot. The 
colour of the larva changes considerably, but is always either pinkish or brownish- 
purple, or a rich yellow-brown, with dark stripe down the back, a double one on top, 
and near the bottom of sides; another quite at bottom, and another down middle of 
belly. On 5th and 6th segments are eye-spots, white, with a tinge of rich yellow above, 
brown below, and surrounded by a black ring; on 9th and 10th segments is a saddle- 
like white mark. Head moderate-sized, rather oblong and reddish brown. Changes to 
pupa between growing leaves, which it knits together with a very tough net-like web, 
and lines it with one much finer and softer; pupa fastened by the tail, which is fur- 
nished with a treble forked bristle in middle with hooks turned outwards, and small 
bristle on each side hooked inward. Pupa conical, front part rather flattened, and 
upper part of thorax rather sharper than usual, but not carinated ; it is engine-turned 
all over except articulations, which are soft ; they are red ; but all the rest is fine shining 
bronze-colour. Feeds on the Hordee suppoo. September and October. Changes in 
twenty-two days.”
