INSKCUTOR INSCITI^ MENSTRUUS 135 



concolorous except the large middle tibial spur and the middle 

 tarsi which together with funicle 6 and the club are white. 

 Fore wings with a broad black stripe across them from the 

 bend of the submarginal vein to apex of the postmarginal and 

 at immediate base fuscous. Tegulse white, black at tip. Ven- 

 ation blackish. Pedicel two-thirds longer than wide at apex 

 or more, the funicle joints short, 1 slightly longer than wide, 

 the others slightly shortening in succession. Club about half 

 the length of the funicle, the latter somewhat shorter than the 

 scape. Head very finely, densely punctulate, with scattered, 

 much larger setigerous pin-punctures. Scutum similarly 

 densely scaly and with dense setigerous pin-punctures. Scu- 

 tellum and axillae sculptured like the head. Abdomen scaly. 

 Hairless line of fore wing with many lines of cilia proximad 

 of it. 



Agrees with the description of Copidosomyia but is different 

 in that the marginal vein is punctiform, the postmarginal elon- 

 gate, slightly shorter than the stigmal. Hind tibiae a little flat- 

 tened, the spur single. Second two teeth of mandible as if 

 formed by a slight concavity of a truncate tooth (thus three 

 obtuse teeth). Club obliquely truncate from base. Lateral 

 ocelli barely separated from the eyes but nearly twice their 

 diameter from each other. Scape long. Axillae with a very 

 short carina between them. Abdomen smaller than the thorax. 

 Tegulas large. One very short ring-joint. Antennae inserted 

 at the ventral border of the mouth, the scrobes absent. 



Four females in the U. S. National Museum. (A. Koebele.) 



Habitat: Australia (Eastern). 



Type: Cat. No. 20674, U. S. Nat. Mus., two females on tags 

 and a slide with two pairs of antennae, a fore wing, head and 

 hind tibiae. Cotype : In the Queensland Museum, a female on 

 a tag. 



Differs from H. obscurus californicus Girault mainly in 

 having the pedicel longer and the club apparently un jointed.
