S/i'ilomena ir'idescensy sp. n. 



$ . Xifjra ; mandibulis tcgulisque flavo-luteis ; antonnis pedi- 

 busque brunco-fcrrugineis ; alis hyalinis, valde iridescentibus, 

 venis I'usco-ferrugineis. 

 Long. 3 mm. 



? . Hearl niucli broader tlian long, broadly rounded be- 

 hind the eyes ; subopaque, niicroscopically punctured, the 

 frontal carina very short, only extendintj: a short distance 

 from the base of the clypciis; antennaj inserted very low 

 down, on each side of tlie clypeus near the apex, nearer to 

 the eyes than to eacli other, the flagellum about twice as long 

 as the scape. Posterior ocelli nearly twice as far from the 

 eyes as from each other; very little farther from the poste- 

 rior margin of the head than from each other. Pronotum 

 very small, depressed below the mesonotum, obliquely sloped, 

 the tubercles of the prothorax touching the tegulaj. Meso- 

 notum and scutelluni subopaque, minutely punctured, a 

 transverse crenulate groove at tiie base of the scutellum. 

 Median segment about as long as the mesonotum, slightly 

 narrowed to the apex, the enclosed area well defined, with 

 two longitudinal carinse near the middle, the space between 

 the carinje and the space between them and the marginal 

 carinaj transversely striated. Mesopleur^e minutely punc- 

 tured, sides of the median segment rugose. Abdomen 

 shining, minutely punctured, sixth dorsal segment without 

 a pygidial area. First abscissa of the radius very short ; 

 second cubital cell much longer than broad, almost as long 

 on the radius as on tlie cubitus, the recurrent nervure inter- 

 stitial with the first transverse cubital nervure. 



Hah. Yallingup, S.W. Australia (T'wr/j^r) ; October. 



This species has the inner margin of the eyes almost 

 parallel, only slightly divergent towards the clypeus. The 

 head is shorter and broader than in other Australian species 

 of the genus, and the position of the recurrent nervure is 

 different. 



Spilomena elegantula, sp. n. 



$ . Nigra ; mandibulis, anteunis, tegulis pedibusque bruueo- 

 testaceis ; alis hyalinis, venis pallide testacois, stigmata infumato. 

 Long. 2 mm. 



? . Head distinctly longer than the greatest breadth, 

 smooth and subopaque. Eyes almost parallel on the inner 

 margin, touching the base of the mandibles; posterior ocelli 

 far apart, farther from each other than from the eyes, as fur
