SYSTEMATIC ACCOUNT. 

 1 . Genus LlPONEURA Lw. 



Antennae are very long and jointless. 



This peculiarity belcngs only to Centr. European and Balkan- 

 species. 



Ail Caucasian larvae hâve antennae two j< inted and short 

 (except the Liponeura caucasica). 



Every bunch of trachéal gills has seven trachéal threads. 

 Claws and feelers on first six segments.

1. Liponeura cinerascens Lw. (fig. 1 C). 



This larva is one of the most common Blepharoceridœ in the 

 whole of Central Europa. 



It was described and pictured by HETSCHKO, in Wien. Ent. 

 Ztsch., 1912. 



The dorsal side of the body is dirty green, the ventral is pale. 

 Antennae are as long as the first body-segment. 



The diameter of the suckers measures 1 /4 of the segment 

 latitude. 



Liponeura cinerascens is very common in the Alps, Carpa- 

 thians, Apenins and in ail Central and West European moun- 

 tains of circa 1000 m. altitude. So for instance in Germany 

 (Harz, Schwarzwald), in Czechoslovaky (Doupov, Sudety, etc.) 

 I also very often found it in Balkan (Mus-alla, Rhodope, etc.}.

2. Liponeura brevirostris Lw. (fig. la). 



This is the second central European species. 



It does not occur so often as the former, but never theless one 

 can find it every where in high Central-European mountains. 



WlERZIEJSKI described the larva firstly from the Carpathian 

 and afterwards many other authors hâve pictured it in différent 

 articles. 



The colour is the same as in L. cinerascens L . 



Antennae are I 1/2-2 x as long as the first body segment. 



The suckers measure 1 /5th of the segment latitude.
