Tlie British Musouiu sunt sevt>ii uiuiaiiu'd siifciuieus of this siteeies 

 for examination ; l)iit they certainly iielonyr to I'asroeus. In the 

 male the fovea nn the u])iier surface of the ahdomei; is |iroflucerl ))aek- 

 waids at the middle, Imt is inoie or le-s rounded, in the female it is 

 subangularly produced backwards. 



Tlie species is very close to Masfcrsi. and I am unable to define 

 any character to distinguish the females. JJut the males differ in 

 the front of the prosternum ; this beiu'jf armed in Mastersi, and 

 umirnied in Pasroeus.

Mr. 11. II. 1). (Jriflith has taken, at Adthiide, nine specimens of this 

 species in nests of a small ant. The female (previously unknown) 

 differs from the male in having- the metasternum regularly convex 

 ana unarmed, the abdumeu convex on under surface, and the legs 

 thinner and unarmed. 



*Arfirf'ri/s I ripynliiris, Lea. 



A male before me, taken at Glenfield, from a nest of Iridomyrmex 

 i/rdrilis, appears to represent a variety of this species. It differs 

 from the type in being slig:htly smaller, in the fovea of the under 

 surface of abdomen nmch smaller and deeper in proportion, and the 

 subbasal impression on each surface of the antennae less noticeable. 

 Mr. H. W. Davey has recently obtained a female at Geeloug. It 

 differs from the male in having the under surface of abdomen and the 

 metasternum regularly convex, and its legs unarmed. Tlie lo[i sided- 

 ness of the antennae is also less pronounced, although cjuite distinct. 



*Arfiri'nis constrict i.cornin, Lea. 



The male has the under surface of abdomen with a wide shallow 

 depression towards the base, and the tibiae more iniiated towards the 

 apex.

M. KaftVays name was puljlished in 1909, consequently his paper 

 was not included in the Zoological Record by the time my own name 

 was published (191(J). There is no need to change my name, how- 

 ever, as the species is the same as M. Uatt'rays, and his specimens 

 were almost certainly taken by Mr. Goudie, from whom I also first 

 received it.
