Tbe following generic description is mainly after Carl and 

 Lebedinsky, witb a few modifications : — 



Antennae sbort, 4-segmented, tbe last segment with sense- 

 bristles. Ant. iii. and iv. not ringed. Postantennal organ 

 externally present or absent. Eyes absent. Protborax rudi- 

 mentary, not seen from above. Mesothorax large, not pro- 

 duced over the bead, rounded in front. Abdomen iii. and iv. 

 subequal. Furcula strongly developed. Denies 1-segmented, 



* Axelson, in 1906, assumed the name Linnaniemi, but, to avoid con- 

 fusion between bis earlier and more recent publications, he suggests tliat 

 both names should appear in reference to his works published since 1906. 



t The specific name elongata having been used by MacGillivray (1896), 

 Axelson renamed the species producta in 1906.
