I5Y AKTHUR WHITE. 73 



tomentum, and a small white tomentose spot behind each 

 shoulder tubercle; sciitellum dark yellow. Abdomen red- 

 brown, coai-sely punctate, with inconspicuous yellowish 

 side-spots, the fourth and fifth segments with narrow yellow- 

 ish hindmargins. Legs with femora, tibiae, and tarsi 

 yellow, the femora clouded with browTi beneath ; femora 

 bare, tibiae with a few black bristles ; anterior tibiae with a 

 terminal cui-\ed spine. Wings almost hyaline, but witn 

 a brown tinge, which is most marked along the costal 

 margin ; first posterior cell wide open ; fourth posterior 

 cell slightly contracted towards the wing margin; halteres 

 yellow. 



This species bears no resemblance to any of the de- 

 scribed Australian species ; it may be at once recognised 

 bv its red-brown colouration, yellow legs, almost hyaline 

 wings, and small size. It is at present only known from 

 a single specimen, which was taken by Dr. Ferguson at 

 Sydney on December 26, 1914.

Moustache pale yellow; face, front, antennae, and 

 thorax red-brown ; abdomen dark red-brown, with pale 

 red-brown lateral spots ; legs red-brown ; wings brown, 

 darkest along the costal margin. 



Lenf/th. Female, 14 mm. 



Hah. Victoria. 



Female. Face and front a uniform red-brown. Mous- 

 tache composed of a single row of stiff pale yellow bristles. 

 Antennae red-brown, a little paler than the face, the third 

 joint slightly broader than the first and second, both of 

 which bear scattered black hairs. Thorax bright claret- 

 red-brown, with three indistinct, darker, rugose stripes, 

 the median one being the narrowest ; scutellum similarly 

 coloured to the thorax. Abdomen dark red-brown, punc- 

 tate, with indistinct pale red-brown lateral spots. 

 Legs with femora, tibiae and tarsi red-brown ; posterior 

 femora with short black bristles ; all tibia? with a few 

 black bristles, anterior tibiae with a terminal curved spine. 

 AVings browTi, a very deep brown along the costal mar- 

 gin, the first basal and anal cells paler than the second 

 basal cell, and the cells towards the wing-tip pale inter- 

 iorly ; all posterior cells wide open ; halteres brownish 

 yellow. 



This species, if one has only the published descrip- 

 tions to go by, might possibly be confused with C. 

 ]iu?irfofiis, Ricardn. 1 have, however, examined the type 

 of the latter species in the British Museum, and find that
