produce their young the self-same year in which they themselves complete 
their transformations, in order that their brood may obtain access to the 
future larva-cells of their non-hybernating foster parents. 
The genera recorded were eight in number, comprising 22 species, 
as follows :—Halictophagus 1; Stylops 5; Hylecthrus 3; Elenchus 3; 
Myrmecolax 1; Xenos 3; Pseudoxenos 8; and Paraxenos 3. Of these 
16 were European (whereof 7 British), and 6 extra-European. 
Mr. Saunders also exhibited a series of specimens, including two new 
species, viz. Pseudoxenos Corcyricus ¢, from Epipone spinipes, L.; and 
Paraxenos Erberi 3, from a variety of the Larra peregrina of Smith (now 
pertaining to the genus Bembecinus of Costa); one of the former, 
together with some others, being retained in situ, when in the act of 
emerging from the pupa-cases in the bodies of their foster-parents. 
The vexed question of the affinity of this class of insects with the 
Coleoptera was adverted to in a preamble.
