This is one of the most common, widely distributed, and variable species of the 

 genus ; on account of the variation of the elytral spots, it has been described under 

 several different names. To judge from the immense amount of material before me 

 from the above different localities, it is evident that the size of the spots and the 

 ground-colour of the elytra are extremely variable ; a small, narrow shoulder-spot is 

 generally, though not always, present. Three specimens of a variety from Teapa have 

 the elytral spots greatly enlarged so as to leave but very narrow dark bands between 

 them ; the underside, with the exception of the fulvous abdomen, black ; this form 

 seems to be rare. 



(Edionychis 8-maculata, Crotch, from Texas, is, according to the description, identical 

 with the present species.

The white frontal patch, shape of the thorax, and the but moderately swollen claw- 

 joint show that this species must be placed in Homophceta. The elytra in several 

 specimens before me are of a yellowish-white colour, with a narrow black sutural and 

 lateral margin, and with or without a similarly coloured shoulder-spot ; anteriorly the 

 sutural black line shows generally a slight dilatation before the middle (which may 

 assume a cruciform-shape, according to Chevrolat) ; the thorax is either of a reddish- 

 fulvous or yellowish colour.

The short metatarsus of the hind legs, the very strongly swollen or subglobular claw- 

 joint, and the flattened sides of the thorax constitute a number of characters which make 

 it comparatively easy to recognize the present genus. Now and then, however, forms are 

 met with which can only be doubtfully placed in Asphcera or (Edionychis, on account of
