SOME ADDITIONS TO THE KNOWLEDGE OP THE NEUROPTEROUS FAUNA OF ROMÂNIA

As a supplement to -sBeitrag zur Neuropteroidenfauna Rumă- 

 niens« von Dr. Peter Kempny, and to «Notes Supplementaires pour 

 le Faune Neuropterologique de la Roumanie« par A. L. Montan- 

 don, I have thought that the following short list would not be 

 without interest. The number of new species added. to the fauna 

 are not many, but apart from these the new localities for the al- 

 ready known species will not be without their value. The species 

 named below have been collected by Mr. A. L. Montan don, who 

 has kindly sent them to me for determination, and to whom I am in- 

 debted for the oppertunity ofclosely examining certain species from 

 East and South Europe, which I have not been able to do before. 



The most interesting species in the coliection are withont doubt 

 Polymitarcijs virgo Oliv. and Cloeon dipterum L. Previously 

 only Heptagenia elegans was the only known species of Ro- 

 mania's Ephmerid fauna, which is certainly the resultof an absence 

 of systematic collecting of Epheinerids from that country, an event 

 that would undoubtedly produce many new and unknown species. 

 as the fauna there must be a tollerably rich one. It would be a 

 great advantage if an energetic collecting of this order could be 

 arranged, not alone for the local fauna, but for the valuable addi- 

 tion it would bring to the knowledge of the fauna of South and 

 East Europe. Should this be to reality, it will not alone prove, as 

 stated before, that a rich fauna is to be found there, but that the 

 Ephemerid fauna will be more varied there than in any other country, 

 as there is no country witli such varie 1 localities for this order 

 as in România. 



The same remarks apply both to the Trichoptera and Plecoptera 

 faunas as to the Ephemerida, although the two first ar<- mucii 

 b r :tt'-r known. 



It i:s extreemly interesting to note that BittdCU8 I Iiujnii ha 

 ■/ discovered again, and that Chrysopa phyllochroma has oc- 

 enrred as an addition to the fuma.
