t o p o g o n. The name was first published by Meigeu as a manu- 

 script name of Megerle's, for a species belonging to the above- 

 mentioned group, a group diaraeteri/ced as having the ilexor sur- 

 face of the fore femora spinose. 



Accordingly, and as skuse ilss'.ij has already stated, 1' a 1 

 p o m y i a may be defined thus: Belongs to the group < ' < r a t o 

 pogou; wings bare, with live radial cells, K, present; media 

 simple; some or all the femora spinose lineal h; pulvilli and em 

 podium wanting. 



Kieffer (1'JOl'j in his definition for the genus includes also those 

 species whose femora are without setae; but it seems to me that 

 Skuse's interpretation of the genus has the claim of priority,, 

 thus leaving C e r a t o 1 o p h u s as a distinct genus and using 

 the name 1* a 1 p o m y i a I'm- those species having sciose femora. 



Subg-enus 1. Alasion rondani

In the analytical table Apogon is briHly desei -ibrd as fol 

 lows: Femora, at least the anterior pair, spinose beneath; 

 antennae of the male vertieillaie with short hairs as in the 

 female. Spec. i.\p.; Ceratopogon h o r t u 1 a n n s Meigen. 

 On page 14, Prodr. II. '57, Kondani changes the name Apogon 

 to Alasion on account of preoccupation. 



C. h o r t u 1 a n u s is made a synonym of C. f 1 a v i p e s by 

 later authors. These authors say nothing of the short-haired 

 antennae of the male, and it appears that there is perhaps some 

 error here on Rondani' s part. The type species C. f 1 a v i p e s 

 is placed among the S e r r o m y i a by Bezzi. This seems un- 

 warranted since the hind femora are not thickened. In the table 

 given by Kieffer (1902) it would fall in the division with Pal- 

 po my ia. 



The name might stand as a subgeneric name as one of the 

 divisions of Palpomyia. It may then be defined as follows: 

 Wings bare, B 2 present, crossvein-like; media simple; some or all 

 the femora spinose beneath, not thickened; the soles (plantae) of 

 the feet hairy, not spinose; in this last character distinguished 

 from S p h a e r o m y a s . Several American species.
