154 LIFE-HISTORIES OF GRACILLARIAD 
On emergence, the pupa protrudes from the cocoon to some extent. Pupal 
period about seven days. (Insectary Cage-slips 1299, 1653.) 
The moths are found at Pusa from August to October. 
ACROCERCOPS AURICILLA, STAINT. (PLATE XXXVIII, FIG. 2.) 
Gracilaria ? auricilla, Stt., T. EK. 8. (2), V, 120-121 (1859)(%). 
Acrocercops cramerella (nec Snell.), Meyr., Exot. Micr., II, 4 (1916)(?). 
Described originally from “ near Calcutta ’’(!). “‘ Reared at Belgachia, 
Bengal, in September from larvee mining in leaves of mahogany, Swietenia 
(Meliacez) *(?). We have it also from Pusa. 
Specimens of affected mahogany leaves were received in the beginning 
of September 1915 from the Principal of the Veterinary College, Belgachia, 
who stated that the leaves were mined and that the trees looked in bad 
condition as a consequence. ‘The leaves were tunnelled on both surfaces by 
mines which at first are long and narrow (not exceeding 0°5 mm.) and irregular 
but which expand into oval whitish blotches, averaging about 11 by 7 mm. 
When the leaf is mined at its edges the mined portion becomes papery, turns 
deep brick-red, and withers. The edges of the outer cover are thickened 
until there is made an elongate space sufficient to contain the pupa. In some 
cases the whitish blotches containing the pupe touch or coalesce with one 
another. 
The pupa is about 7 mm. long and 1 mm. broad; head brown with a 
ventral triangular structure with dentate sides, eye-cap large, antenna-case 
brownish-yellow, reaching to first abdominal segment and spotted irregularly 
with black ; first pair of legs short, reaching to end of thoracic region ; second 
pair of legs reaching to anal extremity ; third pair of legs projecting 1:5 mm. 
beyond anal extremity; thoracic region dorsally with short brown hairs 
arising from small rounded raised tubercles ; thoracic segments yellowish- 
brown ; abdominal segments pale, tinged with green and with short brown 
hairs on small rounded raised tubercles, spiracles distinct and appear like 
rounded brown holes at the anterior end of each segment. 
ACROCERCOPS TELESTIS, MEYR. 
Acrocercops telestis, Meyr., E. M. M., XLVII, 213 (Sept. 1911)('); Lefroy, 
Ind. Ins. Life, p. 538 (1909)(?) ; Fletcher, Entl. Note 87 (1916)(8). : 
Described from specimens reared at Pusa from larve mining leaves of 
Trewia nudiflora (Kuphorbiacee)(:*), Also reared at Coimbatore in February 
1913 from larvee on Trewia, and at Pusa in August 1907 from Gmelina arborea
