84 Cy M: EF. von HAYEK 
Mai 1916. Vitalis de Salvaza; Adelocera tonkinensis Fleut., type [Fleut.]; type 
de la fig. (MNHN, Paris). 
Paralectotype: I ex., Tonkin, Chapa. 4.v.1918. Jeanvoine, without Fleutiaux’s 
determination label (MNHN, Paris). 
Lacon tumulosus (Candéze) 
Adeloceva tumulosa Candéze, 1888 : 668. 
Lacon tumulosus (Candéze) Fleutiaux, 1926 : 93. 
Holotype. Burma: Plapoo, Tenasserim, aprile 1887, legit L. Fea. (MCZN, 
Genoa, according to Binaghi, 1941c : 120.) Not confirmed. 
The generic attribution is based on the description. 
Lacon unicolor (Candéze) 
Adelocera unicoloy Candéze, 1874 : 21. 
Lacon unicoloy (Candéze) Fleutiaux, 1926 : 93. 
LECTOTYPE (present designation). IRAN: 9, Persia; unicolor Cdz. [Cand.]; 
Adelocera unicolor Cand., type [Gahan] (BMNH). 
Lacon vicinus Candéze 
Adelocera vicina Candéze, 1891Ic : 772. 
Lacon vicinus (Candéze) Binaghi, 1941c : 119. 
The description is based on two specimens from BurRMA: Palon (Pégou) collected 
ix.1888 by Fea. 
Type-material. Burma: 1 4, Palon (Pegu) agosto-settembre 1877 [sic], legit 
L. Fea (MCSN, Genoa according to Binaghi, 1941c : 120). Binaghi refers to this 
specimen as the holotype but as the description is based on two specimens it must 
be regarded as a syntype until a lectotype has been designated. The second 
specimen may also be in the MCSN, Genoa or in the IRSNB, Brussels. 
Candéze remarks that this species is probably a variety or subspecies of A. modesta 
[Boisduval]. Fleutiaux (1926: 93) lists it as a synonym of Lacon modestus 
(Boisduval), but Binaghi considers that it should be treated as a valid species. 
The generic attribution is based on Binaghi’s redescription of the syntype.

Ecole normale supérieure, Paris).
