Spilomena iridescens, sp. n. 



5 . Nigra ; mandibulis tegulisque flavo-luteis ; antennis pedi- 

 busque bruneo-ferrugineis ; alls hyalinis, valde iridescentibus, 

 venis lusco-ferrugineia. • 

 Long. 3 mm. 



$ . Head much broader tlian long, broadly rounded be- 

 liind the eyes ; subopaque, microscopically punctured, the 

 frontal carina very short, only extending a short distance 

 from the base of the clypeus; antennae inserted very low 

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

 the eyes than to each 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 tegulge. Meso- 

 notum and scutellum subopaque, minutely punctured, a 

 transverse crenulate groove at the base of the scutellum. 

 Median segment about as long as the mesonotum, slightly 

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

 two longitudinal carinse near the middle, the space between 

 the carinaj and the space between them and the marginal 

 carinas transversely striated. Mesopleuras 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 the cubitus, the recurrent nervure inter- 

 stitial with the first transverse cubital neivure. 



Hab. YallingLip, S.W. Australia (Turner) ; October. 



This species has the inner margin of the eyes almost 

 parallel, only slightly divergent towards the clypeus. The 

 head is shorter and Isroader than in other Australian species 

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

 different. 



Spilomena elegantula^ sp. n. 



$ . Nigra ; mandibuhs, auteunis, tegulis pedibusque bruneo- 

 testaceis ; alia hyalinis, venis pallide testaceis, 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 far
