82 LIFE-HISTORIES OF GELECHIADA 
Little is known in India regarding any parasites or other natural enemies 
of this insect. Mvcrobracon sp. and a Bethylid have been reared and at Surat 
a Braconid was reared and is figured in Indian Insect Pests under the name of 
Urogaster depressarie. In Egypt, Willcocks has given, on pages 233-269 
of his monograph (8), a list of the parasites met with, and in Hawaii Swezey 
has also listed the parasites of this species (Proc. Hawaii Ent. Soc., 111, 101-109 ; 
1915). Buseck has also published notes on Parasierola emigrata, Rohwer 
(Insec. Inscit. Menstr., V, 3-5; 1917) and Willcocks has recorded an Acarine 
parasite (Bull. Soc. Ent. Egypt 1913, 68-72; 1914), and this last, or a very 
similar species, also occurs in India. 
GELECHIA TAMARICIELLA, Z. 
Gelechia tamariciella, Zeller, Stett. Ent. Zeit., 1850, 153 (4); Stainton, Tin. 
S. Europe, pp. 80-81 (1869)(?) ; Rebel, Cat. Lep. Pal., 11, 151 (1901)(3). 
Teleia tamariciella, Rebel, Iris, XX VI, 90 (1912) (4); Chretien, Ann. S. E. 
France, 1916, pp. 473-474 (May 1917) (5). 
Originally described from Tuscany (}), this species is also recorded from 
Spain (?), Southern France (8), North Africa, Syria (*), and Egypt (5). In India it 
appears to be widely distributed throughout the Plains and probably occurs 
wherever Tamarix grows. We have it from Peshawar, Charra, Pusa and 
Basra. 
In Egypt the larva has been found on Tamarix(*) and has been described 
by P. Chretien(5) and at Pusa it occurs commonly on Tamarix gallica and has 
been collected in February, May and December. The larva feeds on the 
dry twigs, binding three or four twigs together and residing in the case so formed. 
It is about 10-11 mm. long and 1:5 mm. broad, tapering posteriorly, reddish- 
brown ; head pale brown, posteriorly irrorated with darker dots, and covered 
with scattered fine grey hairs; prothorax pale brown; mesothorax deep 
brown ; legs black, brownish apically ; warts I and II black, emitting three 
or four short black hairs; lateral tubercles similar but larger, an ill-defined 
dark dorsal line bordered by minute white dots; five pairs of prolegs. In 
another larva the head and thorax were described as green, other segments 
dull brown, green ventrally. 
The larva seldom emerges from its case which it sometimes carries about 
with it, retreating inside when disturbed, It is therefore easily overlooked. | 
In captivity pupation took place inside a flimsy cocoon formed by fastening 
three or four twigs together and attaching them to the bottom of the cage. 
The pupal period is about eight days in May and fifteen days in February.
