Notes, complementary to the Synopsis 

 (referring to the numbers in the square brackets). 



1. I have no hesitation iu referring Tipida idriensis Scopoli to 

 Ctenophora himacidata. Schiner (Scriptores austriaci etc.) recognized 

 a Ctenophora in it, without making up bis mind as to the species. 

 The female in Scopoli may be doubtful. — 



2. Loew, Beschr. Eur. Dipt. II, 24, speaks of the specific identity 

 of Ct. atrata and rußcornis as highly probable. But long before 

 him, Euthe had been of the ßame opinion (Oken's Isis 1831, p. 1207) 

 and Erichson had observed a case of copula of atrata $ with rufi- 

 cornis Q. (apud Ruthe, 1. c). Imhoff (in the Insecten der Schweiz 

 1836 — 41) had made a similar Observation and had reached the same 

 conclusion. More recently Mr. G. de Rossi set the question at rest 

 by breeding 12 males and 15 females from an old stump of alder; 

 7 of the males belonged to the typical form, 5 to the variety ruß- 

 cornis; both copulated freely with the females. (Katter's Entomol. 

 Nachr. 1882, p. 296).
