Closely allied to L. foveatus, presenting scarcely any difference i \ 
the elytra, but the thorax is not alutaceous and sub-opaque as in tha \ 
species, and the legs are of a different colour. By 
St. Paulo & Pebas, Upper Amazons. In my own collection and 
that of Mr. Ed. Brown.

The most common and generally distributed species throughout the 
Amazons region, in moist, muddy places. It is likely to be the same 
as Gory’s bipunctatus, if we may assume the description of that author 
to be inaccurate in several essential points. According to that de- 
scription, the legs would be black and the three basal joints only of the 
antenne reddish; but in none of my specimens is there any approach 
to blackness in the colour of the legs ; they are always (trochanters in- 
cluded) of a pallid-brown hue or reddish testaceous with the base and 
apex of tibiw slightly darker. The small anterior pale spot of elytra 
might readily be overlooked, as it is often reduced to two specks on ad- 
joining interstices, and in one of my specimens disappears altogether. 
It is just possible that this may be the Anchoderus (sic) submaculatus, 
Motsch., Bull. Mosc., 1864, p. 334.
