of Lepidoptera which from their habits appeared to be in 
danger of extermination; that this resolution had received 
the approval of the Council, who would refer the matter back 
to the Committee, in order that definite proposals for the 
formation of such an Association might be drafted, and it was 
hoped to lay these prcposals before the Society for discussion 
upon April 7th. 
Mr. Champion exhibited, on behalf of Messrs. Godman and 
Salvin, a portion of the Elateride, and the Cebrionide and 
Rhipidoceride recently worked out by him in the “ Biologia 
Centrali-Americana.”’ The Elateride included 5381, the 
Cebrionide 29, and the Rhipidoceride 14 species, a large 
proportion of which were described as new. He stated that 
his labours had been much facilitated by the free access to 
the very extensive collection of Elateride formed by the late 
BK. W. Janson, and by the loan of many types from Dr. Can- 
déze, who had lent valuable aid. He called attention to the 
excessive rarity of the males in the Hlaterid genera Chalco- 
lepidius and Semiotus (the contrary being the casein the genus 
Scaptolenus of the Cebrionide, and also in many Klateride), 
and to the fact that the sexual characters of Semiotus had been 
misunderstood, the supposed males being really females. In 
the ‘fire-flies,”’ Pyrophorus, a genus containing a large 
number of extremely closely-allied forms, important specific 
characters were detected in the genitalia of the males. One 
species, Meristhus scobinula, Cand., was common to Central 
America and China. 
He also exhibited a specimen of Hudectus giraudi, Redt , 
found by himself at Mendel, in the Austrian Tyrol, in July 
last. This is a rare European species of Staphylinide, a 
black variety of which (/. white?, Sharp) had once been found 
in Scotland, on the summit of Ben-a-Bhuird. 
Mr. Jacoby showed a Halticid beetle, taken in Mashuna- 
land by Mr. G. A. K. Marshall, and remarkable for a prolon- 
gation of the hind tibia beyond the tarsal articulation into a 
very long serrated process. 
Mr. Elwes showed a series of Papilionide of the Machaon 
group, from North America, including P. machaon and P. 
oregonia from British Columbia, P. brucei, P. bairdit, and
