PROCEEDINGS OF SCIENTIFIC SOCIETIES. 499 
Mr. M‘Lachlan exhibited a portion of a wooden case containing hides 
from Shanghai, which was riddled with borings of the larve of this beetle. 
Prof. Westwood remarked that some years ago the attention of the 
Society was drawn to the depredations of this beetle in a cargo of cork. 
Prof. Westwood exhibited drawings of the pupa of a trichopterous insect 
(Anabolia nervosa), which swam about in water like a Notonecta, but used 
its middle legs as swimming apparatus. Prof. Westwood also made 
remarks upon the structure and situation of the mouth organs of the 
pupe of Trichoptera, and stated that the mandibles of the pup were 
unlike those of the larva, while these organs were quite aborted in the 
imago. The Professor suggested that the mandibles of the pupa were for 
the purpose of enabling the insect to eat its way out of the case in which it 
had undergone its transformation, and in which, after cementing down the 
mouth, it was obliged to turn itself completely round, so as to escape at 
the opposite free extremity. 
Mr. M‘Lachlan confirmed this view of the function of the mandibles of 
the pupe. 
The President next exhibited a small lepidopterous insect from Lake 
Nyassa, apparently a species of Psyche, which had been sent in a paper 
packet with a pupa-case of a Tachina, from which it was stated that the 
moth had been produced. Prof. Westwood was inclined to believe that 
the larva of the moth might have simply made use of the empty pupa-case 
to undergo its transformation in. 
Prof. Westivood read a post-card from Mr. Albert Miiller announcing the 
formation of an entomological station at Basle. 
The President then referred to the lepidopterous larva attached to a 
specimen of the homopterous Hurybrachys spinosa, which had been handed 
over to him by Mr. Wood-Mason at the last meeting, and exhibited drawings 
of both insects, the former being evidently identical with the species formerly 
described as being parasitic upon Fulgora candelaria (Trans. Ent. Soc. 
1876, p. 519). In the absence of direct observation, the President was 
inclined to believe that the relation of the lepidopterous larva to the 
Homopteron was one of true parasitism, the former insect feeding on the 
waxy secretion of the latter, it being well known that certain lepidopterous 
larvee of the genus Galleria feed upon wax, 
Mr. Wood-Mason stated that the interesting specimen which he had 
handed to Prof. Westwood at the last meeting consisted of a lepidopterous 
larva clinging by its anal pair of prolegs to the free extremity of a stout, 
tough, flaccid cord, which was firmly fastened to the dorsal surface of the 
abdomen of the Homopteron. The specimens were captured in August or 
September, 1876, at Bangalore, South India, by Mr. G. Nevill. The 
caterpillar was closely allied to Epipyrops (West.). The cord to which it 
was clinging, Mr. Mason considered to be the wet and matted remains of a
