A typical Mexican specimen in the Stockholm Museum is here figured. This species 
also varies in the colour of the corium, which in some varietal forms is red. Its only 
distinctive character from L. convivus is the more elongate form of the pronotum and 
abdomen. Stal1, in his “ Differentia Specifica,” wrote “ pectore pedibusque immacu- 
latis;” but this, when a series of Mexican specimens are examined, proves to be 
incorrect, as it resembles L. convivus in these respects, being either totally without 
these markings, or having even the bases of the femora red, as in extreme forms of the 
other species.

I have been quite unable to separate Z. cinctus, H.-S., in all its varietal phases 
from L. varians, Stal, with its number of varietal forms described by that author. 
There is little doubt that had Stal been able to examine the long series of Central- 
American specimens now before me, he would not have described his Colombian speci- 
mens as a distinct species. The four specimens figured, of which figs. 16, 17, and 19 
are from Panama and fig. 18 from Guatemala, show the varietal extremes; but even 
here it is evident that some of the Panama specimens approximate more closely to the 
Mexican type than do those from Guatemala. Stal put considerable reliance on the 
colour of the membrane of his LZ varians, “ venis concoloribus;” but in some Bogota 
specimens in my own collection the veins are dark, and this character is uncertain 
throughout the whole series from various habitats.
