Melsheimer’s collection is in the MCZ Harvard but up to the present time the 
specimens have not been located. 
The interpretation of the species is based on a specimen determined by LeConte: 
I g, yellow disk (= Western States); A. impressicollis (Say) LeC. lepturus Say, 
senilis Germar [LeConte]; Adelocera impressicollis Say (MCZ, Harvard). 
Adelocera senilis Germar. LECTOTYPE (present designation). U.S.A.: g, H 
fon green triangular label, ? = Hertz, see below]; North America; Janson coll. 
ex Schaum, 1903.130; senilis m. lepturus Say. Amer. bor. 879? [Germar] (BMNH). 
Germar received the material from Virginia, on which he based his description, 
from Zimmerman and Hertz. The appearance of the name ‘lepturus Say’ on the 
label is puzzling. The explanation may be that Germar learned of LeConte’s 
(1859a ; 620) synonymy and altered or replaced his original determination label. 
LeConte (1859a@ : 182) states that E. lepturus Say (1836: 128) does not differ 
from wmpressicollis. The description of Elater lepturus is based on an unrecorded 
number of specimens from ‘Pennsylvania, Indiana and North Carolina. Harris’. 
As the material cannot be found in the Say collection (see p. 279) in the ANS, 
Philadelphia or the Harris collection (see p. 276) in the MCZ, Harvard, the type 
material must be presumed to be lost. The synonymy cannot therefore be con- 
firmed. 
Lacon inaequalis (Candéze) 
Adeloceva inaequalis Candéze, 1857 : 67. 
Lacon (Aulacon) inaequalis (Candéze); Golbach, 19696 : 157. 
LECTOTYPE (present designation). CoLomBiaA: 9, Columb. [sic] Dup. 29; 
Collection Chevrolat; inaequalis Cand., type [Fleut.]; Adelocera inaequalis (Chev.) 
Cand., type Mon.1. 1857 p. 67. 21 Nova Grenada. D. Dupont [Chevrolat] (MNHN, 
Paris). 
The published locality is ‘Nouvelle Grenade’ the name by which Colombia was 
known between 1831 and 1861. 
Lacon incommodus Fleutiaux 
Lacon incommodus Fleutiaux, 1934é : 364. 
LECTOTYPE (present designation). PHILIPPINES: 3, Davao, Mindanao, Baker; 
Lacon incommodus Fleut., type ex Adelocera [Fleut.] (MNHN, Paris). 
This species has never been included in the genus A delocera. 
Lacon incomptus (Kraatz) 
Adeloceva incompta Kraatz, 1832 : 319. 
Lacon incomptus (Kraatz) Fleutiaux, 1926 : 93. 
The description is based on an unrecorded number of specimens collected by 
Haberhauser near Samarkand [UZBEck S.S.R.]. 
Type-material: ? Kraatz collection, DEI, Eberswalde (Horn, 1935 : 141).
