from the funicle, joint 1 subequal to funicle 3, 2 shorter with 

 a distinct terminal spine; ring joint distinct. Forewings 

 typical; very broad at apex; hyaline; marginal cilia short; 

 discal cilia absent for about proximal half, thence rather 

 dense; submarginal vein distinctly broken, the marginal long, 

 the stigmal short, the postmarginal wanting. 



Hab. — Queensland : Cairns district (numerous females 

 reared from egg-cases of a Blattid, Ellipsidion pellucidum, 

 on leaves of sugarcane, November, 1914, A. P. Dodd). 



Type. — Three females on a tag, head, forewing, and hind 

 leg, on <a slide. 



Closely related to the other three members of the genus, 

 lividas, Girault, silvensis, Girault, and veternosus, Girault. 

 However it lacks the short median carina between the 

 diverging carinae, present in the two former species ; differs 

 from lividus also in the short first funicle joint, and from 

 silvensis in the slender tibial spurs ; separated from veternosus 

 by the straight posterior margin of the second abdominal 

 segment. 



Pleurotropomyia aeneoscutellum, Girault. 



Segment 5 of abdomen with two rows of pubescence, 6 

 with about four rows, 7 with still more. Eyes rather densely 

 pubescent; vertex with very fine scaly sculpture and scattered 

 small setigerous punctures ; a median groove runs from 

 anterior ocellus to about upper third of face where it joins 

 a fine cross-groove running from eye to eye, the face below 

 this deeply excavated, very brassy, and without sculpture 

 except for a few cross-lines dorsad. Median lobe of scutum 

 with a single puncture bearing a long seta on either side near 

 anterior margin, the puncture on smooth inner area of 

 parapsides single, and a similar puncture rather far laterally 

 on scutellum at two-thirds its length. 



Taken frequently on leaves of sugarcane, and a single 

 female bred from leaves of sugarcane, infested with a leaf- 

 mining Tineid, Cosmo pteri/x, sp., Cairns district, June, 1915, 

 A. P. Dodd.

Head with fine dense scaly reticulation ; vertex broad ; 

 f rons normal, without sutures or enclosed sclerites ; antennae 

 inserted a little above ventral end of eyes. Thorax slender;
