laterad of tlie dorsomesal line, the mid-point of alpha and gamma opposite 
to delta ; beta close to dorsomeson at the corners of the advanced row 
of 4-5 teeth ; delta ventrocaudad of beta, adjacent to the terminal 
lateral tooth of the anterior line of teeth ; rho near to and level with 
epsilon, both of which setae occur on the less strongly chitinised lateral 
extension of the shield ; Kappa group trisetose, with theta, kappa and 
eta arranged in a triangle on 3 separate pinacula, cephalad of the spiracle, 
the middle seta the longest and ventrad, the caudal seta the shortest ; 
Pi group of two non-adjacent setae. 
MESO-AND METATHOKAX.—(fig. 10, T. II & III) alpha and beta 
dorsal on one pinaculum, alpha mesad of beta ; epsilon and rho sub¬ 
dorsal on one pinaculum ; theta caudad and slightly dorsad of kappa ; 
eta ventrad of and equidistant from kappa ; (the spiracular scar lies 
within the triangle formed by these 3 setae); Pi unisetose. 
ABDOMINAL SEGMENTS. I—VII—(fig. 10, A. Ill) alpha nearer 
to the dorsomeson than beta ; on segment 1 the distance apart of the beta 
setae is about 3-5ths that of the alpha setae, but this decreases gradually 
in the posterior direction, until on segment 8 the relative distances apart 
of the alpha and the beta setae are sub-equal; traces of a minute seta 
on the anterior segmental margin cephalad of beta (hidden in the retrac¬ 
ted body) probably represent epsilon; rho supraspiracular, pinaculum 
prominent; cephalo—dorsad of the spiracle is a minute seta, visible in 
middle-sized larvae, but worn off in mature larvae, which I am unable 
to homologise, and unable to detect with certainty on segment 8 ; kappa 
and eta adjacent, on one pinaculum, subspiracular; mu on a longi¬ 
tudinal fold behind the middle of the segment, in a line with beta; Pi 
group trisetose, triangular, lateroeephalad of the proleg ; sigma meso- 
cephlad of the proleg. 
VIII. —[fig. 10, A. VIII] alpha and beta setae subquadrate ; epsilon 
as in segments I—VII; rho cephalad of the spiracle owing to the eleva¬ 
tion of the latter ; kappa-eta as in segments I—VII; mu ventrad of them ; 
Pi bisetose. 
IX. —-[fig. 10, A. IX] beta setae closer together than alpha setae ; 
epsilon as in previous segments, dorsocephalad of alpha ; rho kappa, 
eta, mu and pi (unisetose) in one fine on posterior margin. 
X. —[fig. 10, A. X] dorsal area with 3 marginal and 1 submarginal 
pairs of setae, fairly strongly chitinised and provided with one or more 
pairs of small denticles near the posterior margin; ventral area with 
about 5 setae grouped on one pinaculum and 5 more disposed singly.* 
* Stebbing [1905, p. 10] describes the caterpillar as “ consisting of a head and 
twelve segments.the 12th or last segment being much smaller than the 
rest ” but his artist correctly figures it with 13 segments, [Z c., Plate i, figs, aa' and bb'].
