This Australian genus was erected for the reception of a female 

 having 16 stemmed antennal segments and 4 palpal segments. Like 

 Haplusia, the third vein unites with the margin well beyond the 

 apex and is joined to subcosta by a long distinct crossvein: the 

 fifth vein is simple, uniting with the posterior margin near the 

 basal half. The type species, C . b e 1 1 a Skuse, is characterized 

 as having almost pyriform flagellar segments, the stem being nearly 

 as long as the basal enlargement, the latter with numerous whorls 

 of hairs, the basal whorl much longer than the rest.

The female of this Australian genus has the antennae about half 

 the length of the body. There are 14 segments, each with a stem 

 one-half the length of the subcylindric basal enlargement, which 

 latter has 2 sparse whorls of hairs. Palpi quadriarticulate. The 

 illustration shows the wing to be rather broad, subcosta uniting 

 with costa Well before the basal half, a distinct, somewhat oblique 

 crossvein, the third a little beyond the apex, while the simple fifth 

 joins the posterior margin near the basal half. This genus appears 

 to be closely related to Johnsonomyia Felt. The 2 genera agree 

 in major characters and it is possible that further study may prove 

 our American forms cogeneric with this Australian species. Type 

 X. volitans Skuse.

This genus may be recognized by the 3 long veins and the finely 

 haired membrane of the acuminate wings, in connection with the 

 5 tarsal segments, the metatarsus being shorter than the preceding. 

 It is separated from Leptosyna KiefY. by the triarticulate palpi. 

 Pero Mein. is preoccupied by Pero H. Serif.
