crubs, the ground colour being pale fulvous or cream-coloured, with scarcely a 
;'ace of dark markings : also two males and one female of Brilus Jlavescens from. 
'reshwater, the three having been found simultaneously in copula ; he mentioned 
ther analogous instances, notably that in which Dr. Knaggs had found a male 
ach of Tortrix heparana and T. viridana, coupled with one female of the latter 
pecies. 
Mr. McLachlan exhibited 12 bred specimens of HypercalUa Christiernana from 
irvas found at Shoreham, in Kent ; he had bred 19 in all. 
Mr. Davis (present as a visitor) exhibited a fine collection of preserved larvae 
f Lepidoptera. 
Mr. Wood (visitor) exhibited bred specimens of vai'ious species of Saturnidce, 
icluding Cynthia, Promethea, Cecropia, and Polyphemus. The species, he remarked, 
11 possessed a more or less strongly developed moveable spine attached near the 
ase of the inner side of the fore-tibiEe, and lying in a groove in the tibia itself. The 
isects used this appendage as a comb, drawing their antennse between the spine 
nd tibia, and thus cleansing them from dust, &o. 
Mr. Jenner Weir exhibited a large exotic beetle of the genus Monochari.us 
rhich flew into the London Custom House very recently ; it had no doubt bred in 
mported timber. 
Mr. Blackmore exhibited a collection of insects, of all orders, formed by him 
it Tangiers, in Morocco. 
Mr. Eaton exhibited microscopic preparations of the anatomy of several genera 
if Ephemeridte. 
Professor Westwood exhibited two extraordinary forms of Chalcididce, from 
^.ustralia and the Amazons respectively ; they were remarkable for very large size, 
md for aberrant development of the abdomen. 
Mr. Smith sent for exhibition specimens ofOpMon macrurus bred from American 
jocoons of S. Cynthia ; the species was more properly parasitic upon the American 
S. Cecropia, but had adapted Cynthia to its purpose on the introduction of that 
insect into America. One of these Gphions had stung Mr. Smith with such severity, 
13 to lead to the belief that poison was introduced into the wound. 
The Secretary exhibited a wooden letter-clip, sent to him by an anonymous 
Borrespondent, in the notch of which an Odynerus had formed her nest. 
Reports on the ravages of the " coffee-borer," by Dr. Bidie, Government Com- 
missioner, were read by the Secretary. 
Sii- John Lubbock communicated a paper on the larva of Micropeplus 
staphylinoides, with drawings ; the form of the larva of this anomalous genus of 
beetles tended to prove that it was wrongly placed in Stapihylinidw, and belonged 
more properly to the Nitidulido'. 
Mr. Eaton read a paper on tlie anatomy of the imperfect condition of Ca;ni.< 
macrura. 
Mr. P. Bates sent a continuation of his paper on Austrahan Heteromera. 
Mr. Kirby sent a tabular comparison of some representative species of Diurnal 
Lepidoptera in Europe, Asia, and North America.
