certain whether the following description applies to M. campestris or to M. 
devincta, Meyr., or M. ramifera, Meyr., as all these three species are common 
at Pusa and the larve have not been distinguished. The larvee form silken 
tubes which go down practically vertically into the soil to a depth of several 
inches. In confinement the larvae have been observed to go right down to the 
bottom of a glass jar through about sixinchesofearth. The tubesare generally 
formed in dry and rather dusty places. The larva feeds apparently on dead 
leaves and grasses available on the ground, but in confinement occasionally 
eats fresh leaves and has been observed to gnaw a cork. The larva is about 
25 mm. long, cylindrical, pale yellow, soft, with five pairs of prolegs ; head 
and upper surface of prothorax thickly chitinized and shiny, reddish-brown 
to black ; the surface of the head and prothoracic shield varies in different 
individuals from smooth to slightly corrugated transversely, but even when 
smooth there is a faint trace of corrugations. (It is not known whether this 
variation is individual or characteristic of specific differences, but no other 
differences were observable.) Pupation takes place in a stiff cocoon formed 
near the bottom of the tube below the surface of the soil. In the case of three 
pupe found on 27th May 1915 the tube in each case had been carried about 
40 mm. below the surface of the soil and at that depth had been closed entirely 
anda cocoon formed at this lower end ; this portion of the end of the tube is 
rather stiff, no doubt rendered so by the addition of a good deal of silk ; the 
remaining portion of the tube is soft like the tubes in which the larve are found 
and the upper end is prolonged slightly above ground-level, its mouth being 
open ; the head of the pupa is turned towards the mouth of the tube and the 
upper end of the cocoon is closed with a rather thick silken membrane which, 
however, is easily burst. On emergence of the moth, the pupa wriggles to the 
surface and the pupa-case is left protruded from the end of the tube or may 
lie entirely clear of the tube. Tachinid, Ichneumonid and Chalcidid parasites 
have been bred from these larvee and pups. Eggs, obtained from bred moths, 
were laid in a cluster, gummed to one another on the wall of a glass cylinder. 
The egg is slightly elongate-oval or cylindrical with rounded ends, about 
0-7 mm. long and 0°5 mm. broad, smooth, hardly shiny, creamy white. (Pusa

MYRMECOZELA LEONTINA, MEYR. (PLATE LIV.) 
Myrmecozela leontina, Meyr., B. J., XXI, 126('). 
Originally described from Kulu(!) emd=Pasat4, this species is abundant 
in the adult state at Pusa in June and July and we have italso from 
Chapra (Bihar).
