iiiL'. but rather sparse and not very lon<>' ; jirotliorax rather sparsely 

 elothed, even at the sides, middle of disc <^lal)rous ; head sparsely 

 clothed, the fascicle on each side of base small and loosely composed. 



Head lightly transverse, feehly impressed between antennae. Eyes 

 .small and prominent. Antennae thin and moderately long ; club 

 rather indistinctly four-jointed. I'rotliorax slightly longer than wide, 

 more convex than usual ; with two small foveae near base, and some 

 distinct punctures almost at extreme base ; each side with a strong 

 oblique impression, which is invisible from above. Elf/t a moderately 

 long, at extreme base no wider than prothorax, sides obliquely dilated 

 to near the middle, and then rounded to apex. ^^f'[/'^ rather long; 

 hind coxae moderately separated. Lcngtli, l.\ mm.

In size and general ap}iearance fairly close to /'(i/rn/i//ff</>sis, l)ut 

 anteimae dcL'idedly thinner, jjrothorax with ditt'eient inqnessions, 

 and no darker than elytra, the latter rather narrower at base, 

 and with shorter clothing. ('oh)J)(>i»'if> is about the same size, but 

 is flatter, wider, and with the sides of the prothorax very differently 

 clothed. Ectatoinniae is dingier, with the club stouter, and elytra 

 nmch more sparsely clothed. Diipliratns is slightly smaller, more 

 sparsely clothed, and with the eighth joint of antennae larger, in 

 })roportion, then the seventh. Micro p^, also occurring with Ponera 

 lutea, has much smaller eyes, and is otherwise different. 



The eighth joint of the antennae is about midway in width between 

 the seventh and ninth, and is slightly shorter than the ninth, so 

 that while it appears best to regard it as belonging to the club, this 

 might almost fairly be regarded as three-jointed, or at least with the 

 joints of su'bcontinuous width. The seventh is almost exactly the 

 shape of the sixth ; the eleventh is about as long as the two preceding 

 combined. The pirothoracic foveae are feebly connected with the lateral 

 inqjressions, but are conq)letely isolated from each other. Scattered 

 aljout the extreme base are some large punctures, a few of which 

 might almost be regarded as small foveae. 



A specimen given to me by Mr. Cox, and taken l)y him in the 

 Illawarra district, from a nest of Sttninnnia lonyiceps ditiers from 

 the type in having the prothoracic foveae less conspicuous (from some 

 directions they appear to be altogether absent), the elytral clothing 

 decumbent, and the antennae somewhat stouter. (^)uite possibly, how- 

 ever, it represents a new species.
