80 C. M. F. von HAYEK 
Holotype. U.S.A.: 2, blue paper disk [=Washington, see p. 277]; A. rorulenta 
LeC., aurorata LeC. [LeC.]; Type 2375 (MCZ, Harvard). 
The published locality is Steilacoom [Washington]. The inclusion of the name 
aurorata LeC. on the determination label presumably refers to LeConte’s (1857 : 18) 
misidentification of the species. 
Lacon ruber (Perty) 
Elater ruber Perty, 1830 : 20; pl. 5, fig. 1. 
Lacon (Monocyrton) rubra [sic] (Perty); Golbach, 19696 : 157. 
The description is based on an unrecorded number of specimens collected near 
S. Paulo, BRAzIL by Spix and Martius. 
Type-material: Spix and Martius material in ZSBS, Munich according to 
Horn & Kahle (1936 : 208). Not confirmed. 
The generic attribution is based on the following specimen: g, Fry. Rio Jan°; 
Adelocera rubra Perty, brasiliensis Cast., Brasilia [Fry] (BMNH). 
This is the species generally known as rubra. This erroneous spelling was first 
used by Candéze (1857 : 67). 
Germar (1840) placed Adelocera brasiliensis Castelnau (1836: 14), described 
from an unrecorded number of specimens from Brazil, in synonymy with ruber. 
As the type material (?7NMV, Melbourne or IRSNB, Brussels) has not been located 
the synonymy has not been confirmed.

Adeloceva vubida Schwarz, 1902b : 195. 
Lacon (Aulacon) rubida (Schwarz); Golbach, 1969 : 157.

Mona [PUERTO Rico].

The generic attribution is based on the description.
