Contributions to tlic Study of the Liponeuridae Lw. 159 



In 1878 (p. 412) I noticed a certain relationship between Apist., 

 Paltost, and Hamm not only in the venation, but also in the 

 coloring, distinguished by silvery and velvet-black spots that occur upon 

 them. Ciirvpira has not yet been described in its mature form; as 

 to Snowia, its short proboscis notwithstanding, it is undoubtedly 

 related to Paltostoma. 



„The relationship of Hapalothri.v with the second group secms 

 to he a very distant one, and appears merely in the resemblance of 

 the venation. The remarkable structure of the ungues, the want of 

 spurs on the bind tibiae, and the hairiness of the whole body sepa- 

 rate this genus from all the known forms of the family" (O.S. 1878, 

 p. 412). This was written seventeen years ago, soon after I had 

 seen specimens of both genera. In the absence of new facts I have 

 no reason to change my opinion, and, with all respect for Loew's 

 anthority, who considered them as closely related, I keep my jugdnient 

 in suspense. 



Speaking of the spurs of Palt, Loew writes as follows (1877, 

 p. 79): „Ihr wirkliches Fehlen bei der mit Palt, so überaus nahe 

 verwandten Gattung Hapal. lässt es mir aber als ausserordent- 

 lich wahrscheinlich, ja als fast gewiss erscheinen, dass sie 

 (die Sporen) in Schiner's P'igur von Palt, keineswegs bloss aus 

 Versehen weggelassen worden sind, sondern dass sie der P. super- 



hiens in der That fehlen Sollte sich die Voraussetzung, dass 



Palt, ungespornte Schienen habe, wider Erwarten als unrichtig er- 

 weisen, so würde ich doch dabei beharren müssen, beide Gattungen 

 wegen ihres so überaus ähnlichen, von dem aller anderen Blepha- 

 roceridae recht verschiedenen Flügelgeäders in eine eigene Gruppe 

 zu stellen, zu deren Characterisirung das Fehlen der dritten Längs- 

 ader und der Schulterader, sowie die Gabelung der zweiten Längs- 

 ader vollständig ausreichen würde." 



This passage Stands in a stränge contradiction to another passage 

 concerning llie spurs of Pali. on the preceding page (p. 78) of the 

 same paper. Here Loew says: (Schiners) „figure shows no trace 

 of spurs, the absence of which is the niore improbable, as they 

 exist in all the other genera which vve have just described, and we 

 find no information in Schiner's letterpress about them." And 

 yet. in bis Analytical table Loew placed Palt, among the genera 

 without spurs! 



Brauer (Zool. Anzeiger, 22 March 188U) pushed the proof of 

 the relationship of the genera much farther, in declaring that Citru- 

 pira torrentium, figured by Dr. F. Müller belongs to the genus
