Exhibitions, dc. 
Mr. J. Jenner Weir exhibited a beautiful specimen of a Noctua 
found at rest in a nursery-garden at Blackheath, in August last. It 
was apparently a new species, and there was some difference of opinion 
among the members as to whether it came near to the genus Dicycla or 
Gortyna. 
Mr. R. M‘Lachlan exhibited three species of the genus Dilar, Rambur, 
one of the rarest genera of Neuroptera-Planipennia. They represented 
D. nevadensis, Rambur, from Spain (the typical species), D. Hornei, 
M‘Lach., from North-West India, and D. Prestoni, M‘Lach., from Rio 
Janeiro; thus the genus, although numbering very few species, and of a 
strongly characterized nature, is widely distributed. Mr. M‘Lachlan alluded 
especially to the singular unilaterally pectinate antenne of the males and 
the long thread-like ovipositor of the females; this latter indicating some 
special habit yet to be discovered. 
The Rey. A. E. Eaton exhibited, as a microscopic preparation, a speci- 
men of Haplophthalmus elegans, Schobl., a woodlouse new to the British 
fauna. ‘Two specimens were found in a garden at Croydon. 
Miss E. A. Ormerod exhibited two Termites nests, forwarded to her by 
Mr. Everard im-Thurn, from British Guiana. One nest was nearly spherical 
in shape, being about two feet six inches in circumference, and encircled 
the small branch of a tree; in structure it consisted of a number of irregular 
chambers or passages, the walls of which were composed of a blackish granular 
substance from gnawed wood; these nests were also stated to be very hard 
and ligneous towards their centre. Miss Ormerod said that in the packing- 
case in which this specimen was received there was a great quantity of 
blackish sawdust, apparently from the injured outer covering, part of which 
still remained, and somewhat resembled rough brown paper. Mr. im-Thurn
