When irritated, this ant vibrates its abdomen, and gives out a sound 
resembling that produced by the Dipteron, Syrilla pipiens. It is appa- 
rently caused by the friction of a dark striated ring forming the second 
articulation of the pedicle.

New genera and sjpecies : — 
Mayria, A. Forel, Bull. Soc. Vaud. xv. p. 369. Abdomen very long 
aud narrow ; first segment more slender than the second, gradually 
diminishing from back to front, and very low ; the whole body long 
and narrow ; pedicle surmounted by a thick node ; frontal prominences 
S-shaped, widely apart, and diverging ; last joint of the antennas a little 
dilated ; otherwise as in Camponotus. Type, not stated. 
Azteca, id. 1. c. p. 384. Allied to Liometopum and Iridomyrmex, but 
differing in the structure of its “gizzard,” and in there being two distinct 
forms of workers. Type, L. xanthochroa, B^og. (^sericea, Mayr). 
Lioponera, G. Mayr, Verb. z.-b. Wien, xxviii. p. 666. Allied to 
Typhlatta and Edton ; belongs to the Poneridee, but the structure of the 
head makes it a connecting link with the Myrmicidee. Type, L. longi- 
tarsus, sp. n., 1. c. p. 667, Calcutta. 
Holcomyrmcx, id. 1. c. p. 671. Antennae twelve- jointed, three last 
joints shorter than the rest together, and thus allied to Aphoinog aster ; 
but the structure of the clypeus allies it with Monomorium Sindi Solenopsis.
