1900.] FROM SOUTH AND CENTRAL AFRICA. 213 



Hab. Salisbury, Mashonaland (G. Marshall). 



Closely allied to P. humeralis Jac, likewise from Mashonaland, 

 but differing in the black disc of the thorax and in not having a 

 black stripe at the lateral margins of the elytra ; the latter in 

 P. humeralis have the sutural band also extending higher upwards 

 and not ending abruptly truncate as in the present insect. 

 P. schimperi Lefev. and P. abyssinica Lefev. are likewise closely 

 allied ; but the first-named species is described as having the 

 anterior angles of the thorax fulvous only, in having a broad 

 transversa elytral band near the apex, and a subquadrate, not 

 elongate, humeral spot. P. abyssinica has similarly coloured elytra, 

 rufous tarsi, and is smaller. Of the present insect three specimens 

 have been sent by Mr. Marshall, ot which one has the elytral spots 

 widened into a broad band like Lefevre's last-named insect, but 

 the tarsi in all are black ; it may, however, possibly be a variety of 

 that insect. 



GrYNANDROPHTHALMA SUBRUGOSA, Sp. 11. 



Entirely dark metallic blue ; antennas black ; thorax strongly 

 transverse, impunctate ; elytra very strongly and closely punctured, 

 the interstices irregularly rugose. 



Length 5|-6 millim. 



Elongate and parallel, the head nearly impunctate, with a few 

 oblique strigaB between the eyes; the latter large, very slightly 

 indented at their lower portion ; epistome with a few punctures, 

 triangularly emarginate at its anterior margin ; antennas black, the 

 basal joint metallic blue, the second and third very short, obscure 

 fulvous, the others strongly transverse ; thorax twice as broad as 

 long, slightly narrowed in front, the sides rounded, with a distinct 

 but narrow reflexed margin, the median lobe broadly produced, 

 posterior angles rounded, the disc impunctate, with a short 

 transverse depression at each side; scutellum broad, its apex 

 truncate ; elytra feebly lobed below the shoulders, closely and 

 strongly punctured, the interstices transversely rugose, less strongly 

 so towards the apex ; below very sparingly pubescent ; the legs 

 rather elongate, the first joint of the tarsi slightly longer than the 

 second. 



Hab. Cape. (Two specimens in my collection.) 



G. aspaltina Crerst. seems to be a closely allied species, but is 

 described with finely and remotely punclured elytra, which cannot 

 possibly be applied to the present species, in which these parts 

 are distinctly rugose and strongly punctured. 



Gynandrophthalma. marginicollis, sp. n. 



Black, finely pubescent below ; thorax transverse, impunctate, 

 the extreme lateral margin fulvous ; elytra finely punctured, 

 fulvous, a spot on the shoulders, a larger one near the suture at 

 the middle, and a transverse band below the latter, black. 



Length 5 millim. 



Of narrow, elongate and parallel shape ; the head black, very
