Genus MARIETTA Motschulsky 



Marietta maculatipes, new species. 



Female. — Length, 0.60 mm. Orange yellow, the wings hya- 

 line for subhyaline at base), the legs silvery white, the tibiae 

 with two dusky bands (incomplete ventrad) equally distributed, 

 the first at apex of basal third, the second at about base of dis- 

 tal third. Caudal margin of abdominal segments dusky. Fore 

 wings with about nine lines of somewhat coarser discal cilia 

 proximad of the hairless line and a small patch farther proxi- 

 mad. Funicle joints annular, subequal ; club 1 a little longer 

 than wide, not quite half the length of the club. Cephalic legs 

 immaculate. 



Male. — The same but the fore wings bear only about six 

 lines of discal cilia proximad of the hairless line, the body is 

 smaller and the antennae only 4-jointed, the club long, solid, five 

 times longer than wide, the funicle joint a little wider than 

 long and rather closely united with the club. 



From five males, six females (G. Compere). 



Habitat, Perth, West Australia. 



Types, Cat. No. 30688, U. S. Nat. Mus., four males, six fe- 

 males on a slide. 



Marietta novicapillata, new species. 



Female. — Similar to capillata but the distal infuscation of 

 the fore wing, usually isolated in that species, is here extended 

 proximad around the caudal and cephalic margins, on the lat- 

 ter more than halfway to the venation (still farther on the 

 opposite margin). Thus, this area is connected with the broken 

 oblique line from stigmal vein as well as with the two isolated 

 marginal areas (one caudad, the other cephalad) and is consid- 

 erably larger than in the other species. 



From five females on a slide (G. Compere). 



Habitat, Perth, West Australia. 



Types, Cat. No. 20689, U. S. Nat. Mus., the fore described 

 specimens.
