pyramica, Rog., is a Dorymyrmex, of wliich genus the workers are only to 
be distinguislied by tlie metanotum from those of Hypoclinea ; 9 varieties of 
Pseudomynyia yracilis, F., are briefly described, including P. bicoh?; Guer., 
diinidiata, Rog., and probably mexicana, liog. 
The same author, Ann. Mus. Genov. ii. pp. 133-155, under the title 
Formicidce Borneenses^'' describes species collected by Doria & Beccari in 
Sarawak, 64 in number. Some synonymy is given, and females or workers 
of known species apparently described for the first time.

Buchanan White notes the habits of a black Formica at Capri, which 
carried seeds of leguminose and other plants along a road to the nest. P. E.

Aphanogaster : J. T. Moggi'idge, P. E. Soc. 1872, p. viii, having kept a 
colony under glass, confirms his previously expressed belief that the insects 
feed on stored grain. 
Camponotus puhescens absorbs fluid from Tettigometra virescens, Latr., as 
from an Aphis : Delpino, BuU. Ent. Ital. iv. p. 342 et seq. The author dis- 
cusses various questions suggested by this unexpected association of species, 
his chief deductions being that Formica was created before Aphis, Coccus, 
or Tettigometra, and that the latter is probably the stem-form of the
