Snellen from P. jusca. A. batavus, Voll., was captured by the 
Rey. HE. N. Bloomfield at Guestling, near Hastings (Trans. Ent. 
Soc. Lond., 1881, p. 154).

A. vestigialis, Foerst.,is added to the six species included in 
Marshall’s Catalogue ; we have a specimen bred by Mr. Champion 
from the case of Coleophora solitariella. ‘Three species of the 
genus are not rare, but are likely to be generally overlooked, as, 
when running over low herbage or on the ground, they bear con- 
siderable resemblance to certain ants and Staphilini. A. microptera 
has been found in the nest of Formica rufa (Ent. Ann., 1861, 
p. 41). Here, as in the other closely-allied genera, the 
hemipterous form is not constant; fully-winged specimens of 
A. hemiptera are not uncommon. Further research will not 
unlikely prove them to be subapterous varieties of the common 
Phygadeuon jumator, or a close ally (cf. Ent. Mo. Mag. v. 157; 
and Trans. Ent. Soc. Lond., 1881, p. 151). Marshall records 
A. nigrocincta, Gr., bred from Hyberma defoliaria. 
Oressius, Marshall. 
Reddish brown, front part of head and metathorax black ; aculeus as 
loug as the 1st segment (female). : castaneus, 2—3+4 lines. 
This fine species is described and figured by the Rev. T. A. 
Marshall, at Ent. Mo. Mag. iii. 194, from two specimens taken at 
the top of a mountain (38500 feet) near Rannoch. Dr. Sharp 
captured one on Goatfell, Arran (2866 feet).
