Sermyloides tjnieasciata, sp. n. 



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

 thorax transverse, narrowed auteriorly, extremely finely punctured : 

 elytra very closely and distinctly punctured, flavous, the margins, 

 a triangular spot surrounding the scutellum, and a transverse band 

 below tbe middle black. 



Length 5-6 millim. 



Head impunctate, frontal elevations broadly transverse, labrum 

 flavous, palpi piceous ; antenna? long and slender, extending to 

 about the middle of the elytra, black, the basal three joints fulvous, 

 second joint small, the third, one-half longer, oblique at the apex, 

 the following joints somewhat thickened, the terminal ones more 

 slender ; thorax transverse, the sides obliquely narrowed in front, 

 nearly straight, the surface microscopically punctured, fulvous ; 

 scutellum fulvous, triangular ; elytra convex, nearly parallel, very 

 closely punctured, flavous, the lateral, sutural, and apical margins 

 black, a triangular sutural black spot surrounds the scutellum, 

 below the middle is a transverse band, widened at ihe suture and 

 at the sides and connected with the black margins, this band 

 encloses a round spot near the apex, of the ground colour ; below 

 and the legs flavous, all the tibiae mucronate ; anterior coxal cavities 

 closed. 



Hob. Salisbury, Mashonaland, on Zizyplius (G. Marshall). 



This is the second African representative of this genus, the other 

 species, S. maculata Jac, having been provisionally placed by me in 

 the genus Sermyla (Trans. Ent. Soc. London, 1895, p. 333). The 

 present species has lately been sent by Mr. Marshall, and another 

 careful examination proves the two insects with far more right to be 

 placed in Sermylokles, which is distinguished by filiform antennas, 

 incrassate penultimate joint of the palpi, a transverse non-impressed 

 and anteriorly narrowed thorax, in having prolonged elytral epi- 

 pleurae, mucronate tibiae, and an elongate posterior metatarsus, also 

 by a very narrow and convex prosternum and closed anterior 

 cavities ; all these characters are present in the two African species, 

 but the antennae have no incrassate and elongate third joint as is 

 the case with the male in the typical form #. basalis. This is, 

 however, a sexual character only, and of no value in classification 

 used by itself. All the species of the genus known until now 

 are inhabitants of the Malayan islands. 



MONOLEPTA STRIATIPENNIS, Sp. n. 



Oblong, very convex ; below piceous, above testaceous, the antennae 

 (the basal joints excepted) black ; thorax very short, remotely 

 punctured ; elytra with extremely close rows of deep punctures, 

 the interstices slightly convex : legs testaceous. 



Length 2| millim. 



Head impunctate, the frontal elevations transverse ; antennae 

 rather long and .slender, black, the lower four joints more or less
