If ah. — Yiftoi'iii : (ieelon<r, ("i'diii a nest ot" Krtdtoni iiui uiffdninini 

 (IT. W. Davey). 



Tlie jirothorax is dark. Imt not ])lack, but I'eo-ardinir it as such it 

 differs from (■d/iJio/tsis in havin<i; the head small, tlu' iirotliorax with 

 sides ol)li(|Ut, to base instead of rounded and antennae lon^'er, ete. 

 Hetrardinu- the uj^ier surfaee as not entirely Wlaik, it would be asso- 

 ciated with 7\isnianieiisis, from which it differs in havinp' the pro- 

 thorax less transverse and darker, and the abdomen not ]>aler at the 

 base than in the middle. 



I'd! ijlohitx hr((('Jii/ pfe.rua, n.s]). 



Of a rather dingy flavous, head and Hfth and part of sixth ab- 

 dominal segments infuscated. With very tine and short pubescence. 



Depressed. Head rather longer and less rounded than usual, with 

 small punctures. Antennae lightly incrassated, extending to base of 

 j)rothorax ; third to tenth joints transverse, eleventh subconical, 

 scarcely longer than two preceding combined. Prothora r very little 

 wider than long, angles rather strongly rounded, side.-? and base feebly 

 rounded ; punctures indstinct. Elytra no longer than prothorax and 

 scarcely wider ; punctures indistinct. Abdomen parallel-sided to apex 

 of sixth segment. Length, 1|, to apex of elytra J mm. 



ffab. — Tasmania : Evandale Junction, from a nest of Pheidole roii- 

 ffirta (A. M. Lea). 



A thin pale species, with exceptionally short elytra, that appear 

 too small to cover wings. Although the colours are somewhat as in 

 ])aIIidomlii()/\ the species is very distinct from that one, being nai*- 

 r.ywer, ])rothorax less transverse, elytra much smaller, al)domen 

 parallel-sided to apical segment, antennae slightly stouter, etc. 



A specimen from Bagdad, from a nest of Ertatowuia meUdl Ini m, 

 probably belongs to this species, but is rather i>aler (jierhaps from 

 immaturity) and smaller. 



Polj/lohini tenuis, n.sp. 



Of a rather dingy ilavous ; head, antennae (base excepted) and 

 elytra tlavous brown ; fourth, fifth and part of sixth abdominal seg- 

 ments darker, sometimes almost black. With very tine, short, pale 

 pubescence. 



Head rounded, punctures very indistinct, eyes moderately pro- 

 minent. Antennae passing base of prothorax ; first joint moderately 

 long, but slightly shorter than second and third combined, these 

 subequal, fourth to tenth transverse, eleventh subconical, as long as 

 two preceding combined. Prothorax moderately transverse, sides and 

 base rather strongly rounded ; punctures very minute. Elytra lightly 

 transverse, scarcely wider than widest part of prothorax, and very
