Mr. T. W. Wood (who was present as a visitor) exhiiiited specimens and drawings 

 of several exotic species of Satinniidre, and made some observations on llieir habits. 

 SaUiruia Cynthia was remarkable for its attitude during repose, the wings being held 

 perfectly horizontal, without any external support, and widely expanded, the hind 

 wings being an inch or more apart. The altitude of S. Promethea and S. Cecropia 

 was very similar to that of a Papilio, and there were other strongly-marked points of 

 resemblance between the SatnrniidEe and Papilionidse, both in form and habits; for 

 instance, the gentle waving up and down of the wings, as if for display, as observed in 

 these moths, was more characteristic of diurnal than of nocturnal Lepidoptera : he had 

 kept a pair of S. Polyphemus alive for a considerable time, and found that they some- 

 limes (particularly the female) rested after the manner of butterflies, hut at other times 

 their wings were horizontal, a large portion of the hind wings, including the ocellus, 

 being hidden by the fore wings. Mr. Wood had also observed that these insects 

 possess a moveable appendage on the under side of the anterior tibiae, which is used 

 as a comb for cleaning the antennte: he had many times seen the males of S. Pro- 

 methea use these appendages for that purpose; the large feathery antenna was 

 clasped at the base between the tibia and the comb, as between a finger and thumb, 

 and was drawn slowly through to the tip, being thereby efi'ectually cleared of all dust 

 and scales or other foreign matters. 



Prof. Westwood said that there was a similar appendage or plate on the fore tibioe 

 of Papilio Machaon. 



Mr. A. G. Butler (who was present as a visitor) exhibited Halia Vavaria and its 

 Dipterous parasite, a species of Tachina, bred from the pupa". 



Mr. Bond, after referring to the cases recorded in Proc. Ent. Soc. 1865, pp. 103, 

 104, of several males of QEceticus and Micropteryx being discovered in simultaneous 

 sexual contact with one female of their own species, mentioned that Dr. Kuaggs had 

 met with a still more remarkable case, inasmuch as he had found a male of Tortrix 

 viridana and a male of T. heparana ia contemporaneous union with a female of 

 T. viridana. 



Mr. Bond then exhibited a female of Drilus flavescens, — the third known British 

 specii!)en of thai sex (vide ante, p. i.), — and two males of ihe same species, the trio 

 having been captured in copula simnllanea near Freshwater, Isle of Wight, 

 on the 12lh of June, 1868, by iMr. H. Rogers, who had supplied the following 

 account: — 



" I captured them on Friday, the 12th of June, at a place called Blackbridge, 

 Freshwater: they were on the high road, and first attracted my attention 

 through the female crawling along and dragging both males behind her. I 

 picked them up and closely examined them, and both males were in cop. with 

 her at the same time, and remained so for upwards of two hours ; both left her 

 within ten minutes of each other. When I first saw them the males were quite 

 helpless." 



Mr. J. Jenner Weir exhibited a fine large Monochamus, which had flown into and 

 been captured in the London Custom House a few days previously. 



Mr. Blackmore exhibited a collection of insects of all orders, captured in Tangier 

 in March and April, 1868. The greater part consisted of Coleoptera, in which 

 Tangier was very rich: during three years Mr. Rulfe had collected there 2700
