that these larve had recently appeared there in great numbers, and were 
likely to prove most useful, as they fed on the eggs of locusts. The larve 
were, in his opinion, Coleopterous, probably those of a beetle allied to 
Cantharis. Mr. Riley had recently described the transformations of certain 
insects belonging to this group, and natives of the United States. The 
young larve on first hatching are thin, active little creatures, which eat 
their way into the cases of locust’s eggs, where they rapidly grow into fat, 
fleshy grubs. Mr. Calvert states that in his neighbourhood a large pro- 
portion of the locusts’ eggs have this year been destroyed by these larva. 
Sir John Lubbock suggested that if the species does not exist in Cyprus 
it might be worth while to introduce it there. 
Mr. Roland Trimen exhibited the wingless female Hymenopteron, of 
which he had recently sent a sketch and brief account to the Society (see 
Proc. Ent. Soc., July 7th, 1880, p. xxiv), and which, from all the circum- 
stances attending its discovery near Cape Town by Mr. C. A. Fairbridge, 
he had strong grounds for regarding as the female of the well-known Dorylus 
helwolus, Linn. He also showed a second specimen of the same female, 
presented to the South-African Museum by M. C. L. Péringuey. 
Mr. Trimen also exhibited six cases fabricated by a South-African 
Lepidopterous larva, of which the outer covering consisted, not of pieces of 
grass, twigs, or other vegetable substances, but of particles of sand and 
fragments of stone. The very peculiar aspect of these cases was due to the 
fact that along each side was attached a series of much larger fragments of 
stone, roughly triangular in shape, and regularly arranged in a single xow, 
with the longest point outwards; the effect of this arrangement being to 
give the case the general appearance of a Myriapod, and indeed a not very 
remote resemblance to Peripatus. These cases (in two instances con- 
taining the living larva) were found in the dry elevated “ Karroo” country 
of the Cape Colony, in the districts of Beaufort and Clanwilliam, and 
were presented to the South-African Museum by Mr. Thomas Bain and 
Mr. J. R. Maquard respectively. Mr. Trimen was unable to rear the larva, 
owing to ignorance of its food-plant; but, from its appearance when out of 
its case, he thought that it would in all probability have furnished a large 
moth of the family Psychide. 
Sir Sidney Saunders read a paper ‘‘On the habits and affinities of the 
Hymenopterous Genus Seleroderia, with descriptions of new species.” 
Mr. Edward Saunders read a paper entitled “ A Synopsis of British 
Heterogyna aud fossorial Hymenoptera.” 
Prof. Westwood read a paper containing descriptions of new species of 
exotic Diptera, with a supplement containing descriptions of species formerly 
published by the author in inaccessible periodicals—R. Mutpota, Hon.
