Species o/Curculionidse/wm Africa. 



379 



the hind pair with four ; the tarsi with joint 2 transverse 

 and not longer than 3. 



Length 7-9 mm., breadth 2 , 5-3*5 mm. 



Cape Province : Willowmore {Dr. H. Brauns). 



Described from ten specimens. 



The genotype, E. thoracicus, Per., is readily distinguished 

 by the two remarkable tufted prominences on the pronotnm 

 (especially developed in the (J), the angular lateral dilatation 

 near the apex of the rostrum in the $ , and by the elongate 

 2nd tarsal joint, which is longer than the 3rd *. 



The very brief description of Timus simplex, Per. {loc. cit.), 

 would almost apply to E. latifrons, but the former species 

 is stated to have a small orbital ridge above the eye and a 

 lateral stripe of dense white scales on the elytra. 



Fiff. 1. 



Enicoderus latifrons, sp. n. 



The male genitalia of E. latifrons are shown in text-fig. 1, 

 with the accessory parts, in the position of rest. On the 

 extreme right is the divided 6th ventrite, corresponding to 

 the 8th tergite ; behind and above this is the irregular bifid 

 plate from which arises the spiculum, a stout chitinised 

 invagination of the membrane which lies beneath the genital 

 tube, but with its free end curved round on to the dorsal 

 surface, thus forming an effective support for the tube. 

 The strongly chitinised median lobe, with its bluntly pointed 

 apical spatula and two long curved posterior struts, is quite 

 of the normal Brachyderine type, forming a closed tube ; 

 the sac projects a short distance behind the tube and is lined 

 almost throughout with minute, closely set asperities ; the 

 tegmen forms a very narrow circular ring, the dorsal portion 

 of which is produced forwards into a very slightly chitinised 

 bifid process. 



* It may be noted that in this species tlie rostrum was described as 

 bearing - five carina?, but the supposed median carina is really a furrow.
