Second notice on the Apiocerina 



C R. Osten Sacken. 



An article by D. W. Coquillett about the geniis Mhaphio- 

 midas 0. S. (in the West-American Scientist, S. Francisco, Jan. 1891, 

 p. 84 — 86) adds some new facts to our scanty knowledge of this 

 remarkable genus, and induces me to return to the subject of the 

 Apiocerina, already discussed by me in a previoiis article (Berl. 

 Ent. Z. 1883. p. 287 i)). 



In establishing the genus Mhaphiomidas (Western Diptera, p. 281 

 1877) I had a Single defective female speciraen only to compare 

 Coquillett had several specimens of M. episcopus 0. S. in both 

 sexes, and a Single male specimen of a second species which he calls 

 JR. Acton. It results from his data that R. episcopus has three ocelli 

 and not only two, as I saw them in my damaged specimen. R. Acton 



i) Readers of this article are particularly requested to introduce 

 into it, before its pensal, the correction published by me iu the Berl. 

 Ent. Zeitsch. 1886, p. 139. 



At that time I had no chilian specimens for comparison and was 

 misled by Brauer's statement about them, a statement which he had 

 based upon Philippi's erroneous figure, without comparing speci- 

 mens. In his: Characteristik der mit Scenopinus verwandten Dipteren- 

 Familien etc., in the Vienna Denkschriften, Vol. XLIV, p. 107 (Separ. 

 51) he separates Anypenus from Apiocera thus: 



The first and second veins, issuing from the discal cell, end before 

 tbe apex of the wing. Anypenus Phil. 



The first of these veins ends before, the second behind the apex 

 of the wing. Apiocera Westw. 



Such a distinction does not exist in nature, as I ascertained the 

 first time I saw a chilian Apiocera; in both cases, it is only the first 

 of the veins which ends before the apex.
