say, more than fifty years. It can exist only in the north, 
and is most common on the borders of the desert of Atacama. 
All the specimens I saw near the Bio-bio died during the 
winter, or were eaten by birds. A very few eggs hatched out 
in a warm corner of a hill, which were destroyed when small. 
A swarm did fly northward from a place on the plains, and 
I have just found a winged specimen and news that they 
bred, though not in numbers. This specimen agrees with the 
Bio-bio ones. 
The Bio-bio specimens were struggling against the cold and 
scanty food. On opening some fifty females the ovaries were 
found in a rudimentary state.” 
Colonel Swinhoe, Mr. Champion, Mr. Elwes, Mr. McLachlan, 
and Mr. Merrifield took part in the discussion which ensued. 
Prof. L. C. Miall communicated a paper entitled ‘ Dicra- 
nota: a Carnivorous Tipulid Larva.” 
Dr. T. A. Chapman communicated a paper entitled ‘‘On a 
Lepidopterous pupa (Micropterya purpurella) with functionally 
active mandibles.”” The author stated that though the pupa 
has been known for thirty years, its remarkably large jaws 
have never been referred to, still less the fact that they are 
employed to tunnel the way for the pupa out of its cocoon and 
through the superincumbent soil. They are active for some 
minutes immediately before the exclusion of the moth; their 
attachments to the moth are such that they are not moved by 
direct muscular action, nor by the movement of any enclosed 
imaginal parts; yet they manifest great power in their move- 
ments and much intelligence. 
Mr. McLachlan said Dr. Chapman’s observations were of 
great value, and tended to show that the position of Micropterya 
was still nearer the Trichoptera than had been supposed. 
New Library Catalogue. 
The President announced that the new Library Catalogue, 
which had been edited by Mr. Champion, with the assistance 
of Mr. McLachlan and Dr. Sharp, was now ready for sale to 
the public at 9s., and to the Fellows of the Society at 6s, 
& copy.
