Bolivar's description makes this extremely well 

 defined species easily recognisable, and there can be 

 no doubt whatever as to its identity with the figure 

 by Savigny in which the peculiar shape of the pro- 

 notal keels is very accurately represented. As Krauss 

 described his Duronia Savigny i from that figure the 

 specific name given by him has obviously a priority 

 over syriaciis Bol. 



The male which has not been described yet is 

 much smaller than the female, w^ith the antennae 

 scarcely dilated basally and quite twice as long as 

 the head and pronotum taken together; likq the fe- 

 male, it has got a distinct, though not quite regular 

 discoidal vein which is not unusual for the members 

 of the genus. Measurements of the male are, as fol- 

 lows : Length of body i4.5 mm.; pronotum 3 mm.; 

 elytra 10. 5 mm.; hind femur 9 mm. Females are very 

 variable in size ranging from 16 mm. to 25 mm. in 

 the length of body.
