a similar band is placed below tbe middle ; below and the femora 

 more or less rufous, tibise and tarsi pale. 



Hah. Estcourt, Natal (G. Marshall). 



This well-marked species agrees in all structural characters with 

 the other species of the genus, but differs in the amount of rufous 

 of the thorax and the underside. 



MoNociDA, gen. n. 



Body elongate ; antennae filiform, the third joint shorter than 

 the fourth ; thorax subquadrate, without depression ; elytra much 

 wider at the base than the thorax, their epipleurse indistinct below 

 the middle ; legs slender, all the tibise mucronate, the first joint of 

 the posterior tarsi as long as the following two joints together ; 

 claws appendiculate, pi'osternuui very narrow and convex ; the 

 anterior coxal cavities closed. 



Amongst the genera with closed coxal cavities, Monocida will 

 find its place near Monolepia and Pseudocrania ; it diifers from the 

 first in its general narrowly elongate shape and the subquadrate 

 thorax, which is much narrower at the base than the elytra, also 

 in the much less elongate metatarsus of the posterior legs ; from 

 Pseudocrnnia the totally different structure of the head and of 

 the antennae separates the genus. 



Monocida sutukata, sp. n. 



Elongate, black, the head anteriorly, the basal joints of the an- 

 teunse, and the anterior legs flavous ; thorax minutely punctate, 

 flavous ; elytra finely and closely punctured, flavous, the suture 

 and the sides black. 



Length 4 millim. 



Head black posteriorly, the vertex very finely granulate and 

 punctured, the frontal tubercles very strongly raised, the anterior 

 portion and the palpi flavous ; antennae extending nearly to the 

 apex of the elytra, slender and filifoi*m, the second joint short, the 

 third twice as long but shorter than the fourth joint, the lower 

 four or five joints more or less flavous, the apical ones fuscous ; 

 thorax subquadrate, scarcely broader than long, the sides slightly 

 constricted at the base, the anterior angles in shape of a small 

 tubercle, the surface minutely granulate and finely punctured, 

 flavous ; scutellum broader than long, black ; elytra broader at the 

 base than the thorax and sculptured similarly, flavous, a sutural 

 rather broad band, narrowed posteriorly, and the sides more 

 narrowly, black or piceous ; underside and the four posterior legs 

 black, liie others flavous.

Platyxantha facialis, sp. n. 



Elongate, testaceous, the terminal joints of the antennae black, 

 the face very elongate ; thorax subquadrate, foveolate and im-
