a highly-magnified coloured drawing of the same, and read the follo-vin^ notes 

 thereon : — 



"The wing-cases, legs and antenna; are perfectly free from the hody, the abdomen 

 being able to move away from them to a considerable extent. 



" The abdomen of the pupa I ex.imined was in almost constant motion, both to 

 and from the wing-cases, and with slight lateral motion. 



"Neither the wing-cases nor the legs appear to have any individual power of 

 motion, but the end of the abdomen would frequently move the ends of the legs by 

 knocking against them. 



" The abdomen was remarkably soft and flexible, reminding one rather of a female 

 Psyche. 



" In front of the head one seems to distinguish both pair of palpi, the antennse 

 and legs, the legs being longer than the antennae, for which 1 at first mistook ihera. 



"The antennse were not symmetrical in the specimen I examined, that on the 

 left side being close to the leg-cases, that on the right side lying nearly across the 

 centre of the wing. 



" Below the eyes and above the pal|)i appears a brown knob, which may possibly 

 represent the tongue; it bears numerous bristles: immediately beneath it are two 

 large brown projections, the use of which I am utterly at a loss to conjecture ; they 

 expand towards the tips, which are scalloped obliquely. 



" Between the eyes, but above them, is a slight protuberance or beak, which is 

 nearly transparent; above it are again some strong bristles. 



"On the back a slender semi-transparent membrane projects upwards from the 

 first abdominal segment. 



" The head is very clearly separated from the thorax, and between the two is a 

 neck or collar." 



The larva was a birch-feeder, but, the perfect insect not having yet been bred, the 

 species was unknown. The appearance of the imago of Micropteryx had long since 

 suggested a doubt whether that genus was truly lepidopterous or trichopterous : the 

 pupa now proved to be, as it were, midway between the proper pupa-forms of those 

 orders. 



Mr. M'Lachlan remarked that though the pupa was certainly a connecting link 

 between Lepidoptera and Trichoptera, it could not be claimed as belonging to the 

 latter order : the legs and antennae did not appear to be entirely free, as was always 

 the case in trichopterous pupae. Moreover, the form of the larva showed that the 

 insect was properly retained among the Lepidoptera. 



Professor Westwood thought the curious neck-tie-like appendage with scalloped 

 edges must be the covering of one of the pairs of palpi. 



Mr. Janson exhibited seven species of Coleoptera, hitherto unrecorded as in- 

 habitants of Britain, viz.: — 



" 1. Patrobus clavipes, Thomson, Sk. Co//. 25, 2 (1857) ; Skand. Coll. 1214,2(1859). 

 Taken by the late H. Squire near Lerwick, Shetland, in August, 1858. 



"2. Harpalus (Ophonus) diflinis, D/^jean, Spec. gett. iv. 196,4(1829); Icon. iv. 

 95, 4, tab. 179, f. 4 (1834). Fairm. et Lahoulb. Faune Ent. Frang. col. i. 121 , 2 (1854). 

 Schauvi, Naturgesch. d. Ins. Deutschl. i. 573, 3 (1860). Taken by himself near 

 Cioydon, Surrey, in September, 1860.
