528 PHTTOPHAGA. 



Hal. Mexico, Presidio (Forrer). 



The design of the elytra in this species greatly resembles that of D. adelpha and 

 D. tibialis, except that the transverse bands in B. variegata are of more angular or 

 dentate shape ; the green colour of the elytra will further assist in the recognition of 

 the species. 



60. Diabrotica selecta. (Tab. xxix. fig. 21, var.) 



Pieeous, the first joint of the antennae green ; thorax green, bifoveolate ; elytra minutely punctured, green, each 

 with an elongate oblique spot at the base, a short transverse band below the middle, and the apex, fiavous ; 

 femora green ; abdomen fiavous. 



Var. Head fiavous ; elytra green, with a small spot at the shoulder, and a narrow obsolete band below the 

 middle, fiavous. 



Length 3 lines. 



Hob. Guatemala, Cerro Zunil, Panajachel, Volcan de Agua (Champion). 



D. selecta differs from B. sex-maculata principally in the shape and position of the 

 fulvous spots on the elytra : the basal spot is of a narrow elongate shape and extends 

 in an oblique direction nearly to the middle ; the second one does not extend to either 

 margin, and is followed by a large ovate spot occupying the entire apex. In the variety 

 the head is nearly fiavous, and the elytra are entirely green and have the basal and 

 postmedian spots only indicated ; in other respects this form does not differ from the 

 type. The antennee have the second and third joints very short and equal ; the basal 

 joint is green, the others pieeous or dark fulvous. The thorax is shining, and has 

 two deep fovese. In the female the elytra show traces of longitudinal costae.

This is such a variable insect that it has been described under three different names ; 

 but the very large amount of material before me enables me to say without doubt that 

 the above forms merely represent varieties of B. fusco-maculata. In the type the elytra 

 are of a bright green, with three pieeous or reddish-fulvous spots or bands ; these spots
