Subfamily Leptopin^. 

 Genus Enicoderus, Per."^ 



This genus was placed by Dr. L. Peiiiiguey in tlic sub- 

 family Tanymt'ciiKe^ near Siderodactylus ; but, despite a 

 certain superficial resemblance, it has no real affinity with 

 that genus, its nearest ally being LeptostethuSj Waterh., in 

 the Li'plopiiKe. 



To the original description the followaug generic charac- 

 ters may be added : — Head with the eyes entirely lateral, 

 the forehead very broad. Rostrum in a different plane from 

 the head, but not separated from it by a furrow ; scrobes 

 curved downwards and ending far in front of the eyes ; 

 mandibles squaniose at the sides and multi-setose^ with a 

 strong median tooth ; mentum transverse, trapeziform, with 

 two erect setpe. Prothorax with well-developed postocular 

 lobes bearing a fringe of setje. Scutellum small, but distinct, 

 circular. Elytra with ten complete stria?, the b.isal margin 

 carinate, the lateral margin not excised near the base. 

 Wings entirely absent. Legs : front coxae contiguous or 

 very narrowly separated, hind coxae meeting the elytra ; 

 tibiffi mucronate at the apex, the corbels of the hind pair 

 terminal, squamose, and enclosed ; the third tarsal joint 

 broadly lobate, the claws free and squamose at the base. 

 Sternum with the gular margin deeply sinuate, the coxae 

 nearer the front margin of the prosternum ; the mes- 

 episterna meeting the elytra, the mese|nmera very much 

 reduced ; the metepisterna comparatively narrow' and 

 scarcely dilated at the base, the bounding suture distinct 

 throughout ; the metasternum between the coxae as long as 

 or longer than the mid-coxae. Venter with the intercoxal 

 process nearly as broad as the coxa? ; ventrite 2 separated 

 from 1 by a sinuate incision, and as long as 3-f 4. 



The genus Timus, Per. (Trans. S. Afr. Phil. Soc. 189:2, 

 J). 128), which is unknown to me, must be extremely closely 

 related to Enicoderus ; the only distinction given that may 

 be significant is that the eyes are slightly pi-ominent and 

 have a small orbital ridge. 



Enicoderus latifrons, sp. n. (PI. XIII. ligs. [), 10.) 



J ? . Colour black, densely elotlud with indefinitely 

 variegated greyish-white, pale fawn, and brown scaling.
