each lobe. Pleural appendaf^es two, the more distal a com- 

 plex arm shaped somewhat as in Jf. quadrlfidus^ the dilated 

 head with dense areas of erect spinalae ; basal appendage 

 profoundly bifid, forking immediately beyond the base ; 

 lateral arm a chitiuized spine that is broad-based, soon nar- 

 rowed into a strongly curved, acicular point directed caudad 

 and finally mesad ; mesal arm a powerful spear-like arm or 

 blade, dilated just before the apex, which ends in an acute 

 straight point.

Molophilus tanypus coloratus, subsp. n. 



Female,^— JjQXLgih. 5 mm. ; wing 6 mm. 



Differs from typical M. tanypus, Alexander, as follows : — 



Size larger. Mesonotum darker. A dark brown pleural 

 stripe extending across the mesepisternum and mesepimeron 

 beneath the wing-root. Femora yellowish brown, the tips 

 conspicuously dark brown ; incisures between the femora 

 and tibiae not conspicuously pale. Wingswhitish subhyaline, 

 extensively clouded with brown, the coloration being on the 

 membrane itself ; the chief brown areas are at the base of 

 Rs, including cells C and Sc ; at the stigma, continued along 

 the cord ; all veins beyond the cord, with the exception of 

 Mi^2i with conspicuous brown seams near their distal ends ; 

 conspicuous seams along the basal deflection of Ciii and Afg, 

 along Cw2, and near the base and tip of vein 2nd A, the base, 

 centre, and apex of cell 2nd A being pale. A series of 

 brown dashes on the lateral margins of the abdominal 

 tergites.

Rhabdomastix [Sacandaga) trichiata, sp. n. 



Female. — Length about 5*8 ram. ; wing 7'2 mm. 



Generally similar to R. neozelandia, Alexander, differing 

 as follows : — 



Mesonotum shiny dark brown, with a thin yellowish- 

 brown pollinosity, so that the surface appears subshiny, 

 without stripes. Pleura less heavily pruinose. Femoral 

 bases only narrowly pale. Wings distinctly tinged with 

 brow^D, the stigma distinct ; brown suffusions along the cord 

 and vein Cu ; other longitudinal veins less distinctly seamed
