1^ ALEUROPTERYX LUTEA,liOW,lT>E^TlCM, WITH CONIOPTERYX 

 LUTE A, WALLa. ? 



BY PROF. J'R. KLA.PALEK, F.E.S 



The question whether the species described under the name Aleu- 

 ropteryx lutea, Wallg., by Low in his paper, " Beitrag zur Kenntniss 



der Coniopterygiden,''' is identical 

 with the species whose name it 

 bears,arose in my mind when I was 

 arranging and naming my mate- 

 rials of ^oh.Gm\din.GoniopterygidcB, 

 amongst which I have detected 

 a few specimens collected in the 

 year 1891 during my excursion 

 in Sudets, and others from the 

 neighbourhood of Prague, all 

 agreeing in the neuration, and 

 distinguished by the twice furcated cubitus. Last year, when searching 

 for more materials, I was delighted to find the same species very 

 abundantly in a third locality in the neighbourhood of Prague. These 

 specimens were likewise quite in accord with the above mentioned. 



When examining my materials more closely I found that they 

 agreed tolerably well with the description and figures given by Low, 

 but there were some little discrepancies. Then I applied to them the 

 description given by Wallengren, with which they agreed very well. 

 Comparing the descriptions given by Wallengren and Low, I came to 

 the conviction that the species described by L5w must be different 

 from Coniopteryx lutea, Wallg. 



For the sake of comparison I give here the description given by 

 Low (A) and the description of my examples agreeing with that given 

 by Wallengren (B), pointing out the differences only. 



A. 



Antennae 26 — 27-jointed in both sexes. 



Their second basal joint with a conical 

 tooth beneath. 



The wings with a very slight brownish 

 tinge and brown neuration. 



Sector radii in the anterior wings simple, 

 arising almost from middle of the 

 radius. 



B. 



Antennae 23 — 2o-iointed in both sexes. 



No tooth on the second basal joint of the 

 antennae. 



Wings with a slight brownish tinge, 

 rather iridescent when deprived of 

 the powder; neuration strong, distinct 

 and brown. 



Sector radii simple, arising a little befoi-e 

 the middle of the radius.
