to ihe lateral mavgins; elytra somewhat flattened, enürely 

 impunctate, tlieir cpipleurae broad; below of rathev lighter colour, 

 sparingly clothed with yellowish pubescenee, tibiae unarmed, the 

 tirst Joint of the posterior tarsi as long as the following two 

 joints together, claws appendiculate. 



From the nearly similarh^ coloiired species of this genus 

 known from Africa, the present insect differs in the coloration 

 of the antennae and the entirely impunctate elytra; the above 

 description is that of the male, in which the last segment of 

 the abdomen has the usual dividcd median lobe, which is of 

 transverse and flattened shape. 



Platyxantha facialis Jae. 

 The description of this species (Proc. Zool. Soc. 1899) 

 was drawn iip fröm a single female specimen. I have now 

 received from the Stettin Museum the male which ditfers con- 

 siderably in the structure of the head from the other sex; this 

 part is produced anteriorlj- to au extraordinary degree and has 

 a deep cavity placed immediately below the antennae, extending 

 as far as the eyes, the lateral margins of this cavity forme 

 highly raised ridgcs below the eres, the lower portion of the 

 face is flattened and narrowed in front; the penis is long, slender 

 and pointed; in other respects there is little difterence between 

 the two sexes. 



Platyxantha Clavareaui sp. n. 



Elongate, fulvous, the antennae (the basal joints excepted) 

 and the abdomen black, thorax sulcate, impunctate, elytra finely 

 and closely punctured, dark blue. 



Mas. The head moderately deeply excavated at the lower 

 portion. 



Length 6 mill. 



Mas. Head broad, impunctate, fulvous, the lower portion 

 flavous, excavated at the middle, antennae closely approached 

 at the base, extending to two thirds the length of the elytra.
