Mr. F. Smiih exhibited living specimens of Physonota gigantea, a remarkably 

 beautiful species of Cassididas, which however loses all its colour within two or three 

 days after death, indeed some of them had faded and become dull during life ; they 

 were brought to Liverpool from Central America in a cargo of logwood, and were said 

 to have dropped out of the cracks of the wood. 



Mr. F. Smith exhibited a smooth corneous luminous larvae from Uruguay, which > 

 he supposed to be a Pyrophorus. When placed in a dark room, the head appeared {^ 

 bright red, and each side showed ten bright green spots ; the lateral spots were almost 5j, 

 always visible (in the dark), the red only occasionally, and sometimes would remain in- P ^ 

 visible for ten minutes together ; the colours were so intense that Mr. Smith compared ^,-' ' 

 them to the red and green signal-lamps of a railway train. It was said by the sender ^^ 

 to be capable of living for two or three months without food, if placed in earth which 

 was kept damp and occasionally changed. 



Mr. Pascoe exhibited a beetle* brought by Mr. Du Boulay from West Australia, 

 which possessed a very peculiar formation of the elytra with remarkable elevations on 

 the hind pari thereof, and which seemed intermediate between Hister and Claviger. 



Prof. Westwood exhibited drawings of two new species of the Ectrephes of Pascoe 

 (Proc. Ent. Soc. 1866, p. xvi. = Anapestus of King, in Trans. Ent. Soc. N. S. W. 

 for the same year), which genus he now considered to be a strangely modified form of 

 Ptinidfe; and of some other forms (Polyplocotes, n. g., &c.) which connected Ectre- 

 phes and Plinus. Also, a new Articerus, a new Paussus, &c. 



The Secretary read a letter from the Secretary of the Flax Improvement Associ- 

 ation of Belfast, respecting the damage done by a small beetle to the flax crop, 

 especially whilst the plant was in the seed-leaf. The species was determined by Mr. 

 Janson to be tbe Thyumis parvula of PaykuU.
