t,o p o g o n. The name was first pulblished hj Meigen as a manu- 

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

 mentioned group, a group characterized as having the flexor sur- 

 face of the fore femora spinose. 



Accordinglj, and as Skuse (1889) has already stated, Pal- 

 pom y i a may be defined thus : Belongs to the group C e r a t o- 

 p o g n ; wings bare, with five radial cells, R2 present ; media 

 simple; some or all the femora spinose beneath; pulvilli and em- 

 podium, wanting. 



Kieffer (1902) in his definition for the genus includes also those 

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

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

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

 the name P a 1 p o m y i a for those species having setose femora. 



Subgenus 1. Alasion rondani 



Dipt. Prodromus. 2:14. 1857. (=Apogon, Prodromus. 



1:175. 1856. Preoc.) 



In the analytical table A p g n is briefly described as fol- 

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

 antennae of the male verticillate with short hairs as in the 

 female. Spec. typ. ; Ceratopogon hortulanus Meigen. 

 On page 14, Prodr. II. '57, Rondani changes the name A p g n 

 to Alasion on account of preoccupation. 



0. h o r t u 1 a n u is is made a synonym of 0. 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 ispecies 0. f 1 a v i p e s 

 is placed among the S e r r 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, R2 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 Sphaeromyas. Several American species.
