CYDIA LEGUMINANA, Z. 227 
the red frass outside traces of larve, I succeeded in obtaining a 
number of pups from which in the following month I actually 
bred five examples of leguminana. 
The next step was of course to investigate the larva, and at 
the end of August in the same year I found a number of larve 
which it seemed almost certain must be this species, but I could 
not succeed in hibernating them; it was therefore necessary to 
procure another supply in the spring of this year, which I 
obtained on March 24th; these pupated in due course, and some- 
what to my relief, emerged early in June as Cydia leguminana. 
I had felt pretty sure they were this species, but could not be 
certain, because there is another species, Phtheochroa schrebersiana, 
whose larval habits are somewhat obscure, and which is found in 
the leguminana district. The pupa cases of this species I have 
actually seen in Hungary sticking out of elm bark. 
DESCRIPTION OF Ovum. 
The ovum is of the usual tortrix shape, horizontal of course, 
about *5 mm. long by °33 mm. broad, dull red in colour when 
deposited on June 30th, 1918; a week afterwards it was light 
grey and slightly opalescent ; the surface was rough and pitted, 
divided into a large number of small spaces, separated by very 
fine raised lines; these spaces were irregularly shaped and the 
dividing lines curved. ‘The divisions were so small and indis- 
tinct that they were not discernible in the microscope with a 
2-in. lens, but they were distinctly made out by using a 1-in. lens. 
On August 4th the larve had emerged, probably some time 
previously. 
A larva measured on August 28th, 1920, was then about 
8 mm. long and in the last instar; of average stoutness, not 
attenuated to either extremity. The head was reddish brown 
and glabrous, the lobes were rather prominent. The prothoracic 
plate was light brown and glabrous with two darker crescents in 
front pointing towards the head. The contents of the intestinal 
canal showing distinctly as a reddish medio-dorsal stripe. The anal 
plate was dark brown and glabrous; the sub-dorsal and ventral 
areas, prolegs and claspers were putty coloured and glabrous. 
The tubercles and spiracles were extremely large and prominent, 
dark greyish brown in colour. The larva was somewhat spiny ; 
it was fairly active, and on being exposed to the light assiduously 
sought concealment and darkness. On October 13th I turned 
out of the tin in which I had kept the larve with the pieces of 
bark on which they fed and found they were all dead and mouldy, 
although on October Ist I had seen a larva crawling on the glass 
lid of the tin. On March 24th last I again procured a number 
of larve. Some of these were spun up in compact cocoons formed 
by the larval frass, and lined with white silk, but some were
