behind the obtuse anterior angles. In one of the specimens from Pinos Altos the 
entire upper surface is mottled with reddish-brown. G. rotundatus will almost certainly 
be found to inhabit the Southern United States. A spotted example from Guatemala 
city is figured. ;

Found in numbers by myself in Guatemala. In this insect the sides of the pronotum 
are straight and obliquely converging from the prominent, rounded lateral angles. The 
markings are very variable, specimens occasionally occurring with the pronotum broadly 
bordered with ochreous at the. sides (fig. 16), or with the basal margin of that colour. 
The locality given by Herrich-Schaffer 1 is simply “‘ America.” |

This very widely distributed species, described by Prof. Uhler ® as “a variously tinted 
chunk of insect entity,” appears to be the commonest member of the genus. It has 
the pronotum much less constricted at the sides than in G. variegatus ; the lateral 
angles are rounded, moderately dilated, and finely crenulate. The general coloration 
is very variable, specimens (from Texas) occasionally occurring with the sides of the 
pronotum very broadly and the basal half of the elytra whitish.
