Hal). iS. Queensland, Caloinidra {^I locker) ; January. 



Nearly related to li. tenuiventris, Turn., but the abdomen 

 is more t^lender in tliat species, the third segnient being mucii 

 longer than broad ; in tenuivenln's ^ the scape has a small 

 spine at the apex, the second joint of the flaiiellum is rather 

 more stronj:lv emarginate beneath, and (he third joint is al.-o 

 strongly emarginate beneath and sidjluberculate at the apex. 

 'JMie epicnemial area is detined in both species. In most 

 Australian species of Rhopidnm the male antennse are not 

 .strongly differentiated, but in 1{. alicia\ I'urn., and R. lejyto- 

 spf^rmiy 'j'nrn., the third joint of the flagellum is strongly 

 emarginate beneath and subtuberculate at the apex. 



Rhopulum testaceum, sp. n. 



$. Testacea ; capita mesonotoque nigris ; maiulibulis, apice ex- 

 cej)to, clypeoque flavis ; antennis tcstaceis ; alis hyalinis, irides- 

 centibns, venis fuscis. 



Long. 4 mm, 



$ . ^landibles acute at the apex, not bidentate ; clypeus 

 brt adiy rounded at the a))ex, with four minute teeth on the 

 apical margin, without a carina. Head smootli and shining ; 

 the eyes se[)arated at the base of the cly|)eus by a distance 

 equal to rather more than two-thirds of the length of the 

 scape ; ])Osterior ocelli as far from the eyes as from each 

 other and about the same distance from the hind margin of 

 the head ; a curved groove from the inner margin of the 

 eye, extending towards, but not reacliing, the posterior ocelli. 

 Pronotum dejuessed below the mesonotum, almoht vertical. 

 Thorax closely and minutely ))nnctured, a tiansverse groove 

 at the base of the scutellum. Median segment smooth and 

 shining, with a distinct median sulcus. First abdonunal 

 segment a little shorter than the second, moderately swollen 

 at the apex, not very slender ; second segment longer than 

 the ajiical breadth ; tliiid segment much broader than h.ng. 

 Hind tibiae very feebly serrate near the apex. Recurrent 

 nervure received a little before two-thirds from the base of 

 the cubital cell ; radial cell oblique at the apex, the costal 

 marorin as long as the stigma, the transverse cubital nervure 

 received jnst beyond one-quarter fiom the base of the cell.

Easily distiiiiiuished by the icniaikable colouring. The 

 first abdominal segment is shorter than in other Australian
