separater! by a mere groove or suture, and not by any breaclth of 

 front. In the rirst section of the Bihionidae the eyes are contiguous 

 in the male only, and the antennae are inseited, not in the middle, 

 between the eyes, but below theni, near the mouth. The eyes of 

 Scatopse are therefore not truly holoptic, and this distinction between 

 the two sections is an anomaly, which reqnires a further explanation. 

 It has never been noticed in any of the existing descriptions. The 

 eyes oi Corynoscelis, judging by Boheman's description and figure, 

 have the same structure as those of Scatopse; the eyes of Aspistes 

 are slightly remote at the top (I have conipared specimens, as well 

 as the figures in Meigen, Loew and Westwood, in Walker's 

 Vol. III). 



There is the genus Anareie Hai. which Loew refers to the 

 Cecidomyidae (Section Lestremina) and Seh in er to the Scatopsina 

 (Fauna Austr. II, p. .353). The antennae of Anarete are without 

 verticils, the venation is very like that of Scatopse, the eyes are 

 reniform. but separate on the front; there are distinct ocelli. Anarete 

 differs from Scatopse in its slender legs, with a very long metatarsus 

 and in its four-jointed palpi. Loew Avould not adniit the relationship 

 of Anarete, with its four-jointed palpi, to Scatopse, whose palpi are 

 almost abortive (Loew, Stett. Ent. Z. 1845). But at that time Loew 

 did not know the genus Corynoscelis, which undoubtedly belongs to 

 the Scatopsina, but nevertheless has three-jointed palpi, and thus 

 forms the transition. In Loew's Dipter. Beitr. IV, Gecidomyia, p. 22 

 he mentions the very large pulvillus (should be empodium) of 

 Anarete, which of itself speaks most decidedly in favor of the re- 

 lationship with Scatopse. I have not seen Anarete, and therefore 

 de visu have no opinion about it.i) 



Scatopse notata is cosmopolitan, probably imported in North- 

 America, Australia and New-Zealand. The european S. recurva and 

 pidicaria likewise occur in North-America (see my Catal. N. Am. 

 Dipt. 1878, p. 17). A species is described by Wol laston from Ma- 

 deira, half a dozen species from China and Argentina, and two from 

 Australia. (The Scatopse from Java described by D oleschall is a 

 Sciara.) Aspistes has been found in Europe and K-America; Co- 

 rynoscclis in the north of Europe only. Loew found sevcral Sca- 

 topse in amber. 



i) Since wiiting fheso lines I have received a specimen oi Anarete 

 ihrougli the kindness of niy friend Mr. v. Röder, and I feel convinced 

 iiow tliat Seh in er was riglit, and lliat Anarete belongs to the Sca- 

 topsina. The legs, for a Scatopse, are remarkably long.
