Species of African Ralticinm and Gcderucinie. 49 



large triangular patch extending narrowly upwards at the suture, 

 fulvous ; under-side and legs fulvous, clothed with fine yellow 

 pubescence, tibia? unarmed, anterior coxal cavities closed ; last 

 abdominal segment of the male deeply incised at the sides. 



Hah. Zambesi. 



Spilocephalus, Jac. (Trans. Ent. Soc. Lond., 1888), is well 

 distinguished by the structure of the antennae and the shape 

 of the thoracic depression, in connection with the unarmed 

 tibias and closed coxal cavities. S. distanti, Gah., and *S^. 

 metallica, Jac, have filiform antennae and a different thoracic 

 sulcus and are better placed m Platyxantlia. In the female 

 of S. apicalis the antennae have the joints less widened and 

 nearly equal, and the last abdominal segment is simple. 



Aulamorphus pichis, sp. n. 



Oblong, black, sides of the head flavous, thorax closely punctured, 

 deeply transversely sulcate at the sides, elytra stronglj' and closely 

 punctured, black, the shoulders and a strongly dentate and semi- 

 crescent shaped band at the middle, flavous. Length 6 millim. 



Head impunctate, with a deep longitudinal central groove, the 

 sides of the vertex and the frontal elevations flavous, clypeus and 

 labrum black, antenn* slender, extending to the middle of the elytra, 

 black, the third and the following two joints elongate, equal, the 

 terminal joints slightly thickened and shorter, thorax about twice 

 and a half broader than long, the sides straight, the anterior and 

 posterior margins curved, the anterior angles oblique, the surface 

 irregularly punctured with a very deep transverse sulcus at the sides, 

 less deep at the middle, another small depression is placed at the base 

 near the middle, scutellum smooth ; elytra slightly wider at the base 

 than the thorax, with a depression below the base, very strongly and 

 closely punctured, black, the shoulders with a subquadrate flavous 

 spot, another transverse and medially constricted mark is. placed at 

 the middle, not extending to the suture but connected near the lateral 

 margin by a narrow stripe with another transverse dentate band near 

 the apex, forming a semicrescent, under-side and legs black, 

 the abdominal segments narrowly margined with flavous, tibiae 

 imarmed, metatarsus of hind-legs as long as the following joint, 

 together, anterior coxal cavities closed. 



Hcd\ German East Africa. 



Of this, the second species of the genus, I only possess 

 a single female specimen, it is however suflSciently dis- 

 tinguished by its coloration, although the latter is probably 

 subject to variation.
