Agathomyia. 23 



5. A. cinerea Zett. 



1852. Zett. Dipt. Scand. XI, 4310, 12—13 {Callomyia). — 1910. Wahlgr. 

 Entom. Tidsskr. 32, 33 et 232, 6. 



Of this species I know only the female; the male has not been 

 described, except the characters given by Wahlgren, from which 

 I take the following: Velvet black; abdomen on the three first seg- 

 ments with yellow side spots which meet on the venter, but not 

 dorsally. 



Female. Frons broad, grey; face and occiput grey. Antennæ 

 black, third joint fully twice as long as broad. Palpi yellow. Thorax 

 grey, above more brownish, in certain directions indicating three 

 broad stripes. Abdomen with the three basal segments yellow, the 

 fourth black, fifth and sixtli greyish, a little silvery, but the fifth 

 black at the sides (or with a dorsally interrupted band). Abdomen 

 sparingly short-haired, the hairs longer and yellow on basal part; 

 sixth segment with hindmarginal bristles both on tergite and sternite. 

 Legs yellow, tarsi darkened towards end; hind legs shghtly dilated, 

 metatarsus almost not but the three following joints somewhat 

 dilated; middle tarsi with the three middle joints a little dilated, the 

 fourth drawn obliquely out at anterior apical corner (as also on hind 

 tarsi). Of bristles only the spur on middle tibiæ present and a small 

 preapical bristle on hind femora. Wings pellucid. Halteres yellow 

 with the knob brownish. 



Length 2,5 mm. 



A. cinerea is very rare in Denmark, I have taken only one female 

 in Geel Skov on ^9/^ 1918. 



Geographical distribution: — Only known from Denmark and 

 Southern Sweden. 



Remarks: As seen there is a little difference in my description 

 of abdomen from those by Zetterstedt and Wahlgren, but as hitherto 

 only single specimens have been at hånd, I think the difference is 

 only variation or due to another interpretation of the abdominal 

 segments. The species was by Schiner and Verrall considered a syno- 

 nym to antennata, but as shown by Wahlgren it is not so. 



When I studied the Platypezids in Zetterstedt's collection in 

 Lund I saw the types of Fallent and antennata and the specimens of 

 elegantula Fall., while viduella and cinerea were not present; these 

 latter I have, therefore, determined after Wahlgren's påpers; this
