collected by him in Switzerland for identification in t852. For 

 greater surety I submitted them also to Dr. Schneider in Breslau, then 

 the best authority for this family. There were in Bremi's collection 19 

 species (two not sent) and all but three with collection names. The 17 

 before me belonged to 12 species, all published. In my publication of 

 Bremi's species, Stett. Ent. Zeit. 1865, P- 230, 3 specimens only are 

 mentioned, the types of which were in my collection. The other 9 are 

 H. nervosus, hiriiis, phahratus, pygmoeiis, limbatus, Iiutuuli, dipterus, 

 nitidiilus, pagafius. 



For H. dipterus {nigcr Bremi in my synopsis), represented by a bad 

 specimen of the female, Bremi remarks: rare near Kaltenbad on the Rigi. 



Dr. Schneider remarked; it is undoubtedly Burmetster's species, 

 but I can not assure the sexes, as the specimen does not allow me to 

 recognize them. As after analogy oi Boreus and many Lepidoptera the 

 aborted wings are to be found on the female, this specimen should be a 

 male. I can not make out now if H. dipterus has been found later in 

 Switzerland and quoted in local catalogues. At least Bremi's specimen 

 was the first known with well developed hind wings. 



A few years later I received from the late Mr. Motschulsky a speci- 

 men with well developed hind wings, mentioned by me among the 

 Russian Neuroptera, Stett. Ent. Zeit., 1858, p. \-^o 2iS Micromus dipterus 

 and by an error as a male. The genitals could not be studied as the 

 specimen is glued with the folded wings on mica. The locality is given 

 Jekatarinoslaf, because a small pink lable with R,m. is on the pin. The 

 abbreviated locality could be as well Jekatarinburg (on the Asiatic side 

 of the Ural) but the insects of this locality have in Motschultsky's col- 

 lection always the label R.m. or. The specimen is still before me and it 

 is the second with developed hind wings seen by me. 



In 1857 I discovered and named in the collection of the late Dr. 

 Stein in Berlin, two males and one female in excellent condition, all 

 collected by him near Berlin. The specimens are now in the lierlin 

 Museum. 



In 1865, Mr. G. Kiinow in Konigsberg, by beating the grass on a 

 cemetery behind the observatory, collected, August 22, two males. Both 

 are in excellent condition and are in my collection. The genitals are 

 visible; a lancet-shaped horizontal blade and the parts below it make it 

 sure that these specimens with undeveloped hind wings are males. Only 

 two years ago Mr. Kiinow collected also the female in the same place, 

 of which I possess the two wings of one side in a microscopical slide. 



In the Hemerobid. synops. synonym., Stett. Ent. Zeit , 1866, 

 p. 376, after the study of 6 males and 3 females which I had the chance 

 to examine of this rare species I established for it the genus Psecirii.
