Ectrephes. 



Prof. Westwood referred to this genus two si^ecies that cer- 

 tainly appear to be generically different from, formicarum, its 

 type. In Thesaurus Entoniologicus Oxoniensis, plate 3, com- 

 pare^ — 



Fig 1. — E. formicarum, Pasc, with 

 Fig 2. — E. hingii, Westw., and 

 Fig. 3. — E. jjcisvoei, Westw. 



It will be seen that the two latter have the prothoras deeply 

 foveate, whilst the first has it without a fovea at all. The 

 antennae also are different. 



In formicarum and hingi the antennae are three-jointed, 

 but the third joint is very different inter se. In pascoei the 

 antennae are figured as six-jointed, but in the description West- 

 wood says, " antennaruni clava oblongo-ovali, depressa, disco 

 supero et infero transverse tri-impresso." The club, according 

 to the figure, is composed of four joints. I believe that the 

 three species should in fact be regarded as belonging to three 

 genera. 



Ectrephes formicarum^ Pasc. 



{Anapestus kreusleri. King.) 

 Taken in ants' nests both in South and Western Australia. 



Ectrephes pascoei, Westw. 



Described as having been taken under bark, but probably 

 there associated with ants. 



Ectrephes kingii, Westw. 



Described originally as from Swan River. Mr. Goudie sent 

 nie a specimen that was " found in a small black ant's nest in 

 a piece of stick lying on the ground, August, 1908.'' Mr. 

 Davey captured a specimen at the same time, and it should 

 now be in the National Museum. 



Enaniha tristis. Oil. 



I have been unable to obtain any additional particulars to 

 those contained in the original description of this species ; but
