African Phytophagous Coleoptera. 227 



This species cannot be mistaken for any of those 

 described by Lacordaire from South Africa, on account 

 of the deeply emarginate epistome in connection with 

 the scarcely perceptibly elytral punctuation ; their lobed 

 epipleurse will separate the species from any similarly 

 coloured Gynandrophthalma, and the subquadrate thorax 

 which has all the angles distinct from Diapromorpha. 



Barybama humcralis, sp. n. 



Black, the basal joints of the antennae flavous, thorax fulvous with 

 some piceous spots, impunctate, elytra finely and closely punctured, 

 flavous, the shoulders with a small black spot, the suture posteriorly 

 extremely narrowly black. 



Mas. Thorax strongly transverse, broader than the elytra, the 

 anterior legs elongate, the femora strongly incrassate, the tibiae 

 mucronate, the first joint of the tarsi slender. 



Fern. Thorax not wider than the elytra, strongly punctured 

 anteriorly, legs and tarsi scarcely elongate. 



Length 3 millim. 



Mas. Head strongly and closely punctured, black, shining, the 

 anterior margin of the epistome nearly straight, mandibles large, 

 more or less fulvous, antennae black, the lower four joints flavous, 

 the fifth and following joints transverse, triangularly widened ; 

 thorax twice as broad as long, the sides strongly rounded, the posterior 

 angles obsolete, the surface impunctate, with the exception of a 

 small number of punctures at the middle of the anterior margin, 

 the disc pale fulvous, with six more or less distinct elongate piceous 

 spots, placed transversely, scutellum pointed, black, elytra finely 

 punctured in closely approached very irregular rows, the extreme 

 apex nearly impunctate, the posterior portion of the suture extremely 

 narrowly and a spot on the shoulders black, below and the legs black. 



Hob. Natal, Malvern (C. Barker). 



This little species, of which I received both sexes from 

 Mr. Barker, agrees in everything with the other ones 

 described by Lacordaire as regards structural characters, 

 but is of small size, and differs in the black shoulder 

 spot and similar coloured posterior portion of the suture ; 

 the female might easily be mistaken for another species 

 since the thorax is remotely but strongly punctured, but 

 both sexes were taken by Mr. Barker " in cop."
