Habitat. S. Braz: Guaruja, Santos, 27. ii. 10, 
several specimens (W. J. Kaye). 
Fig. 7 represents a Correbidia, while fig. 7a is its model 
Calopterum braziliense. Both insects were caught together 
on a very dwarf-growing species of Ageratum with small 
white flowers on 27th Feb. ’10. The specimen figured of 
the Coleopteron is not the specimen that was taken, but is 
a specimen of the same species from Rio Janeiro. The 
species is very variable, and if one had taken a number of 
the insects at Guaruja it is highly probable that one would 
have secured a specimen exactly like the moth. The 
difference in the specimen figured of the Calopterum and 
the single example taken is that the Rio specimen has more 
black on the base of the elytra. It has been figured in 
preference also because it is in a perfectly natural position 
and so corresponds with the Syntomid, which also is in a 
perfectly natural position of rest. 
The similarity of these Lycid beetles with Syntomid moths 
has been noticed by several writers. The heavily pectinated 
antennae with the pectinations carried to the tip strongly 
suggest the stout-jointed antennae of the beetle. The 
abdomen is rather flattened like the beetle, while the shape, 
colour and manner of folding of the wings is most suggestive 
of the beetle, while finally the legs are short and correspond 
with the legs of the Lycid. The habits of these two 
totally different insects are extraordinarily alike. They 
both sit on flowers in the early morning, and both drop off 
if alarmed and draw the legs in. At such times (early
