Australian : Machimus forresti Dakin and Fordham

The immature stages of Machirmis atricapillus have 

 been studied by Beling (1882) and Melin (1923). 



Verrall (1909) placed Asilus nigripes Macquart in 

 liis appendix list of Palaearctic species as a synonym of 

 Machimus setibarbus Loew. 



Subgenus Conosiphon Becker 



Conosiplion Becker, Revision der Loew'schen Diptera Asilica in 

 Linnaea Entomologica 1848-1849, p. 36, 1923. Type of sub- 

 genus: Dj/smachus panpcr Beclier, 1907, by original desig- 

 nation. 



Becker (1923), on the basis of certain differences in 

 the female terminalia (ovipositor) and the character of 

 the mesonotal pile, proposed the name Conosiphon to 

 distinguish several European asilids, especially from 

 Machimus Loew, sensu stricto. Tlie characters given 

 by Becker (1923) and Engel (1928) are here set forth: 

 (1) Face gibbosity strong and prominent and occupy- 

 ing most of the face and with a well developed ledge 

 above; (2) Dorsocentral bristles prominent on the front 

 portion of the mesonotum; and (3) End lamella of the 

 ovipositor not wedged in as in Dysmachus, but style- 

 like in profile. 



A total of five species of Machimus were assigned by 

 Engel (1928) to the subgenus Conosip^hon. Three of 

 these, pauper Becker (1907), fuscus Macquart (1839), 

 and corsicus Schiner (1867), were included in his key 

 to Machimus and specifically designated as belonging 

 to the subgenus Conosiphon. Two others, alter Becker 

 (1923) and similis Becker (1923) were unknown to 

 Engel and were included only in his text; these two 

 species, together with fuscus Macquart are included in 

 Engel's text in the subgenus Conosiphon, whereas cor- 

 sicus in the text was assigned to Tolmerus Loew, a 

 further subdivision of Machimus, in the wide sense. 

 I call attention here to the use of the name pauper 

 Becker (1907) for the species he described vmder the 

 genus Dysviachus Loew and in Becker (1923) made 

 the type of the subgenus Conosiphon, and which Engel 

 (1928) designated as belonging to the subgenus 

 Conosiphon under his text figure, but not otherwise in 

 his text. The other species of pauper Becker (1923) 

 was described as a Tolmerus and is left in Engel's text 

 in Tolmerus. Under the Tolmerus species list I have 

 included both pauper Becker (1923) and corsicus 

 Schiner (1867). Although I have pointed out above 

 that Engel (1928) included corsicus Schiner in his key 

 under subgenus Conosiphon he placed corsicus in his 

 text imder Tolmerus.
