times in the length, dorsal surface with a few sharp tubercles, but the 

 number or size not as great as in the male, ventral carinas slightly ele- 

 vated, finely serrate-dentate in the distal half and with an indication of 

 the pregenicular diastema of the male; caudal tibise of female straight, 

 slightly longer than in the male. 



General color, clay color marked more or less with prout's brown. 

 Antennae cinnamon. Pronotum with a narrow median area and the 

 ventral portions of the lateral lobes of the general color, as well as a 

 large irregularly quadrate or rectangular patch on each side. Mesono- 

 tum and metanotum with an irregular system of broad alternating 

 pale and dark bars, the abdomen bearing the type of markings only 

 more numerous, smaller, and more restricted to the caudal margin of 

 the segments. Cephalic and median limbs sometimes clouded with 

 the darker color; caudal femora with the tubercles and serrations dark, 

 in the female the pattern of musculation being more truly scalariform 

 and not with a broad medio-longitudinal interruption as in the male.

This interesting series shows that a considerable amount of variation 

 in size exists in this form. While this feature is very apparent it is not 

 as conspicuous as the variation in color, which latter ranges from a 

 decidedly straw-colored type (the predominating phase) to a blackish 

 brown form with no trace of the usual coloration, except a very narrow 

 pale margin to the ventral portion of the lateral lobes and a few small 

 spots on the vertex and fastigium. In many respects this dark type 

 superficially resembles Mexican specimens of G. assimilis, from which,
