the terminal three joints Ijlaclvish, tlie intermediate joints slightly 

 triangularly widened, of equal length, the second one short, thorax 

 one-half broader than long or rather broader, the sides feebly 

 rounded, the anterior angles more distinct than the posterior ones, 

 the surface with a very short and obsolete depression anteriorly and 

 a slightly more distinct one at each side, entirely impunctate, 

 fulvous ; scutellum of tlie latter colour ; elytra with a distinct

 extremely finely granulate, under-side and the legs fulvous. 



Rah. Salisbur}^ Mashonaland (G. Marshall). 



The above description applies to what seems to be the 

 male insect ; in the female, the thorax has a deep, trans-

 somewhat thinner, otherwise there is no difference. 



Eunjcycla, gen. n. 



Body elongate, glabrous, anteun;e filiform ; thorax transverse, 

 broader than the head and as broad as the elytra, narrowed anferiorl}^ 

 elytra metallic, irregularly lanictured, epipleurpo prolonged^ pos- 

 teriorly, tibife unarmed, the metatarsus of the posterior legs as long 

 as the following joints together, claws ajipendiculate, anterior coxal 

 cavities open. 



Type. E. halyi, Jac. (sub Megalognatha). 



It is impossible to leave this species in Ilegalognaiha, as 

 the thorax is of totally different shape without any

Heniicantha fiavicornis, sp. n. 



Black below, upper-side testaceous, the antennse very long, flavou-^, 

 thorax subquadrately transverse, impunctate, elytra subcylindrical, 

 extremely minutely punctured, tibite unarmed. 



Length 4^ millim. 



Elongate and parallel, the head impunctate, the frontal elevations 

 strongly raised, transverse, clypeus triangularly convex, antenn;ic 

 nearly as long as the body, flavous, the apical joint stained with fuscous, 

 the third twice as long as the second, but shorter than the fourth 

 joint ; thorax one-half broader than long, the sides rather strongly 

 rounded at the middle, the anterior angles obliquely thickened and 

 slightly j)roduced, posterit^r margin sinuate, oblique at the angles, 

 the disc with some minute punctures, only visible under a strong
