wings, " con qualche brizzolatura chiaro." Ficalbi's description, however, fits this 

 species much better than it does 0. mariae. The two Itahan specimens were both 

 determined by Prof. M. Bezzi, who has seen Rondani's collection. Judging from 

 the description, it seems highly probable that Loew's C. leucacanthus is the same 

 species. 



The larva is unknown. The male hypopygium differs from that of A. mariae 

 and A. zammittii in having a single distinct spine on the basal lobe of the side-piece, 

 the structure being otherwise similar. 



Distribution. — Italy (Toscana, near sea, Ficalbi ; Faenza, E. Hargreaves ; 

 Macerata, Bezzi) ; Macedonia (Bajirli, near Snevce, Water ston) ; Persia (Kasan, 

 Loeiv) ; Paris [Berland, Segtiy) ; Croatia (Novi, Horvdth) ; Chitral (Drosh, Walker, 

 1915 ; per Capt. P. J. Barraud).

This species may generally be distinguished from others of the group by its 

 darker colour ; the femora (especially the hind pair) have more numerous dark scales, 

 the white rings on the tarsi are narrower, and the mesonotum is much darker, the 

 pale scales occurring mainly on the posterior third and often forming a pair of spots 

 just behind the middle and indistinct pale lines in front of the scutellum. There 

 appear to be two more or less definite forms : a smaller, with entirely dark-scaled 

 wings and distinct pale bands at the bases of the abdominal tergites, and a larger, 

 with scattered pale scales on the wings and the abdominal bands more or less obsolete, 

 the pale scales which are present occurring as much towards the apices as the bases 

 of the segments. The peculiar male hypopygium, with its divided basal lobes and 

 very broad appendage to the claspettes, is the same in both forms. 



I am still unable to distinguish satisfactorily the larvae of A. macuiatus and 

 A. annulipcs* but the two species are certainly quite distinct. A. macuiatus is 

 essentially a woodland species, while A . annidipes (and most others of the group) 

 prefer more open breeding-places. 



This species has generally been known as A. cantans, though Meigen's description 

 will apply as well or better to one of the other species of the group. P^or this reason 

 Lang adopted the later name imterhousei. M. Seguy, however, informs me that males 

 of this species are labelled C. cantans in Meigen's collection in Paris, and the identi- 

 fication of Theobald, de Meijere and others must therefore be regarded as correct. 

 Meigen himself states that his C. macuiatus was the male of C. cantans, and this state- 

 ment must be accepted, since the type of C. macuiatus no longer exists to prove or 

 disprove it. Many of the earlier records of C. cantans apply no doubt to other species 

 of the group. 



Distribution. — Apparently confined to Europe, occurring chiefly north of the 

 Alps. I have seen males from Britam ; France {Seguy, Langeron) ; Belgium 

 {Goetghebuer) ; Denmark {Wesenbcrg-Lund) ; Sweden (Stockholm, Boheman ; 

 Smaland, Haglund) ; Finland (Kymmene, Sallm.) ; Germany (Urdingen and 

 Frankfort-an-der-Oder, Riedel ; Berhn, Oldenherg, Lichtwardt) ; Austria (Polzleinsdorf, 

 Schiner ; Moritzburg, Kunize) ; Hungary (Mimkacs, Ujhelyi) ; also females, 

 probably of this species, from Lappland (Qvikkjokk), and Italy (Turin, Sangone, 

 coll. Bezzi). 



* ?>€g\xy's figxxve oi" A. cantans" in Bull. Mus. Paris, 1920, p. 327, really represents A. 

 communis ; his later figure of " O. cantans " in Bull. Soc. Ent. France, 1920, p. 310, probably 

 represents A. littescens (see Seguy, Bull. Soc. Ent. France, 1921, p. 165).
