Lacon funebris (Solsky) 
Adelocera funebris Solsky, 1881 : 231. 
Lacon funebris (Solsky) Fleutiaux, 1926 : 3. 
The description is based on an unrecorded number of specimens from ‘valle 
Sarafschan’ [= Zeravshan, TADZHIKSTAN S.S.R]. 
The type-material is probably in the ZMV, Moscow (E. B. Britton in litt.). 
The generic attribution is based on the following specimen: TURKESTAN, 
Q-15.vii.1960, determined by Skopin (BMNH). 
Schenkling (1925: 9) records the date of publication of this species as 1882, 
apparently referring to a separate with pagination 1 —. The separate is unknown 
to me. There seems to be no reason why the date on the title-page of the Hovae 
Soc. ent. ross. '? should not be accepted.
