Subgenus Palamopogon Bezzi 



Eupalamns Jaennicke, Berliner Ent. Zeitschr., vol. 11, p. 86, 

 1867. Type of genus : Cyrtopogon longibarbus Loew, 1857, 

 as Eupalamus alpestris Jaennicke, 1867, by monotypy. 

 Preoccupied, Hymenoptera, 1845. 



Palamopogon Bezzi, Mem. Soc. Ent. Italiana, vol. 5, p. 61, 1927. 

 Change of name. 



While Engel (1930) and Seguy (1927) both place 

 Eupalamus in synonymy under Cyrtopogon Loew, with 

 no mention by either of them of Bezzi's action in chang- 

 ing the name, it is possible that these flies should be 

 recognized as Bezzi has suggested, at least as a sub- 

 genus of Cyrtopogon. There is considerable difference 

 in the figure of the head as given by Seguy and taken 

 from Jaennicke, and the figure given by Engel in the 

 above cited references. According to descriptions of 

 Cyrtopogon longibarbus Loew, the scutellum is bare 

 except for discal pollen and black marginal hairs. It 

 would appear to be readily separable from the Nearctic 

 Nannocyrtopogon Wilcox and Martin by the absence 

 of stout and conspicuous scutellar bristles. There is 

 only the one species assigned to this subgenus. 



Genus Lithoeciscus Bezzi 



Lithocclsous Bezzi, Mem. Soc. Ent. Italiana, vol. 5, p. 61, 1027. 

 Type of genus : Holopogon heydeni Loew, 1871, by original 

 designation. 



Small flies which appear to be related to Holopogon 

 Loew through the character of the stout hind tibia and 

 hind basitarsus but which are probably more nearly 

 related to Nannocyrtopogon Wilcox and Martin. 

 From this last named genus they differ in the shorter 

 face covered with numerous, long, fine, bristly hairs. 

 The third antennal segment is long and scarcely con- 

 stricted at base. The scutellum is flat, although the rim 

 is rounded ; its disc is densely appressed micropubescent 

 without other pile and the margin has several bristles. 

 Abdomen is rather bare and sternites with only a few, 

 scattered, fine, long hairs. Mesonotum has well de- 

 veloped dorsocentral bristles beginning at the middle. 

 Length 9 mm. 



Head, lateral aspect : The head is of medium length, 

 the face quite short and barely visible in profile 

 throughout and retreating below as the eye recedes. 

 The occiput is moderately prominent throughout its 

 entire height but recedes at upper and lower eye cor-
