Studies on Tipulidae. , . 185 



iiitrodiiced for one of tliose species of Tipula, that liave abortive wings 

 in the female sex. As the rest of tlie Organization is eutirely ui;,- 

 changed, such a genus, based on one sex only, has no foundation. 

 Compare Loew, Wiener Entom. Monatsschr. VIII, p. 124 (1864), who 

 is of the same ßpiniou. 



Älophroida Rondani, Prodr. I, p. 188 (1856), is insufficiently 

 characterized in the analytical table of the genera, which precedes 

 Rondani's work. The type is a new species, A. cinerea which re- 

 mained undescrib«! ; it is some Tipulid with au open discal cell. 



Macromastix, 



Nomen novum for Macrotliorao) Jaennicke, Neue Exot. Dipt. p. 11, 

 Tab. 1, f. 2 (1867) preoccupied in Lioy, I ditteri etc. 1864, p. 261. 



When Mr. Jaennicke introduced the genus Macrothorax for 

 M. ornatus from Australia, he had, it seems, no distinct conceptiou 

 of the genus Megistocera, to which he compares Mac7'othorax. He 

 had before him the type of Wiedemann's Megistocera hraziliensis 

 which is no Megistocera at all, but apparently a Pacliyrrhina with 

 abnormal antennae. »What other .forms he had, I do not know, but 

 the Statement in bis descriptioh that the venation of Macrothorax 

 „is the same as in Megistocera" proves that he had not compared 

 a true Megistocera. The concequence was that bis description, 

 based upon a mistaken comparison, is not cleai\ Moreover the species 

 he describes, M. ornatus, has a largely developed thorax and a 

 comparatively small abdomen, on which M. Jaennicke lays a great 

 deal of stress, but which cannot be considered as characteristic of 

 the genus. 



There are several species of Tipulina from Australia and New- 

 Zealand, provided with very long antennae in the male sex, and with 

 a tubercle on the front, which I consider as congeneric with the 

 Macrotliorax ornatus Jaenn. , and which (the name 3£acrothorax 

 being preoccupied) I propose to call' Macromastix.- They have been 

 all described as Megistocerae. 



I shall attempt to draw the generic character of Macromastix 

 from specimens of M. vulpina Hutton, which I have before me, as 

 well as from notes taken by me from the other species of the genus, 

 which I have seen in diiferent coUections.
