The larvae are growing slowly, and feed upon the cultivated yellow-flowering Genista, drilling regular little round holes in the leaves. BRITISH HYMENOPTERA. A piece of heather containing three cocoons of the Sand-Wasp (Peloposus, sp. inc.) were presented to the Society by Col. Irby, F.Z.S., and produced two imagines 23rd and 24th instant. BRITISH NEUROPTERA. The larvae of Libellula depressa have done well; but those of Agrion, sp. inc., have all died. It is probable that these species require running water of a temperature not above 50°. Ephemera, sp. inc., grew well, and produced two imagines. EUROPEAN NEUROPTERA. Myrmeleon formicarius.-Fifteen larvae of this insect were obtained from France, and have established themselves in some sand in a glass shade, exhibiting their pits as in a wild state. BRITISH COLEOPTERA. Imagines ofDytiscus marginalis, Hydrophiluspiceus, and Cicindela campestris exhibited. One larva of Dytiscus marginalis was exhibited for half the month, when it was attacked by a species of fungus and died. BRITISH TRICHOPTERA. Caddis-flies {Phryganea, sp. inc.).-These have lived, and many are probably mere pupae. EXOTIC ORTHOPTERA. Eggs of 5 species of Leaf-insects were received from Mr. Water-house, British Museum, and are exhibited in a suitable vessel should they hatch. There have also been exhibited :- BRITISH HEMIPTERA. Notonecta glauca, and eggs obtained, which hatched and attained half growth. Nepa cinerea', and Aquatic Spiders (ARACHNIDA). GENERAL REMARKS. I have not been able to add a number of species that I should have wished, owing to a severe illness, which suddenly attacked me on the 14th instant. |
