182 C R' Osten Sacken: 



only 8 joints; last Joint of the palpi skort. As the sex of the spe- 

 cimens is not mentioned and forceps or ovipositor not described, 

 I conclude that the latter are very little couspicuous and the sexes 

 perhaps difficult to discriminate. 



I have seen specimens belouging to these genera in different 

 collections, but my notes about them are very incomplete; the only 

 Impression I retained is that these genera are closely related. I think 

 that Tipida tiigrithorax Macq. D. E. Snppl. IV, p. 15, Tab. 1, f. 4 

 (Tasmania), and perhaps also Tipida clavata Macq. ; 1. c. p.' 14 

 Tab. 1, f. 4 (Tasmania) belong to Leptotarsiis. However, the an- 

 tennae of the latter (1. c. f. 4 a) are figured as comparatively long, 

 12 or 13 jointed; the last Joint of the palpi as whiplash-shaped etc. 

 Tipula tricincta Walker, List etc. I, p. 73 also seems to belong here. 



YI. The Tipulina ia the narrower sease. 



_ The genera belonging here are: Ozodicera Westw. (which has 

 already been discussed in § IV, among the forms with pectinate an- 

 tennae); Macromastix (Syn. Macrothorax Jaenn.); L,ongurio Loew, 

 Holorusia Loew, Stygeropis Loew, Tipida Linn., Pachyrrhina 

 Macq. and Neplirotoma Meig. 



Concerning Loew's new genera, I have neither notes nor specimens 

 before me, and therefore merely translate the descriptions , adding 

 such remarks as my recollections may suggest. 



Sty geropis Loew, Centuriae IV, 42 (1863) was at first pu- 

 blished under the preoccupied name of Prionocera in the Stett. Ent. 

 Zeit. 1844, Tab. 2, f. 30, head; fig. 31, rostrum and palpi. It was 

 characterized thus: „Corpus pubescens, abdomen cylindricum, breve; 

 alarum nervi palporumque fabrica ut in Tipula; antennae 13-articu- 

 latae, subtus serratae, crassiusculae, pilis verticillatis destitutae ; pul- 

 villi desunt." Among these characters the: antennae subtus ser- 

 ratae, crassiusculae pilis verticillatis destitutae alone is 

 of any value for the characterisation of the genus. The pul villi 

 desunt c'an merely iiiean that' the empodia are small and inconspi- 

 cuous, because in describing the north american S. sordida (1. c.) 

 Loew says: empodio majore differt. Schiner says 'distiuctly : em- 

 podia narrow, but present. 



The original species S. pubescens Loew, from Posnania, was 

 considered by Schiner, Fauna austriaca II, p. 521, as a synonym of 

 Tipula Diana Meigen; Loew however, although he recognizes a Styge- 

 ropis in Tip. Dianci, maintains S. pubescens as a different species 

 (see the note to the descriptiou of S. sordida in Centur. IV, 42).
