Two critical remarks about the recently-published 



third part of the Muscaria Schizometopa 



üf MM. Brauer and Bergen stamm; also a noticc on 

 Robineau-Desvoidy, 



bv C. R. Osten Sacken. 



Two years ago, when I received the second part of the Mus- 

 caria Schizometopa, I was somewhat astonished to find, on the 

 very last page of the Index, p. 142 [446], the words: „Torocca 

 Walk. — Uns unbekannt." Recently, owing to the kindness of the 

 authors, I have received the third volume, and I find again in the 

 Index, p. 150 [238], the same words: „Toroca Walk, (sie!) — Uns 

 unbekannt." 



The genus Torocca was described by Walker in the .Journ. Proc. 

 Linn. Soc. Vol. IV, p. 131, Sept. 185tJ; the species is T. abdominalis 

 n. sp. from Makessar. A second niention of Torocca occurs in the 

 same Journal etc. Vol. IX, p. 5, with the following notice: „Felder 

 has named a genus of Rhopalocera after Dr. Doleschall, and as 

 my genus JJoleschallia is very closely ullied to Torocca, I have 

 unitcd these two genera and have anuUed the fornier name." However 

 MM. B. & B. would have also found a mention of Torocca in the 

 yearly Entoni. Bericht for 1859, p. 29i> (by Gerstaecker) if they 

 had taken the trouble carefully to comi)ile the literature of the Mus- 

 cidae, before Publishing their monograph. 



Another passage in the same third part, which attracted my 

 attention is the following, on p. 2 (90): „Beschreibungen Robineau's, 

 die um so weniger Vertrauen einflössen, als derselbe die morpholo- 

 gischen Vorhältnisse der Muscaricn so wenig kannte, dass er eine 

 Fliege mit zufällig eingezogener Stirnblase, die der ganzen Familie 

 gemeinsam ist, als neue Gattung beschreibt (Rondania cucidlata)." 



The passage alluded to is in the „Dipteres des environs de 

 Paris" (I, p. <i77; 1863) and runs thus: „coti'S du front et de la 

 face en saillie, et comme recouvrant les antennes d'une sortc de 

 capuchon" etc. Whether this passage has been correctly interpreted 

 by Messrs. B. & B., I am unable to say, but what I know is, that
