in closely approached rows ; legs and antennae pale, the apex of the 

 latter and that of the posterior femora, as well as the breast, 

 black. 



Length 2 milliro. 



Head impunctate, obscure dark fulvous, the frontal elevations 

 absent; antennas extending somewhat beyond the middle of the 

 elytra, flavous, the terminal joints more or less fuscous, basal 

 joint long and slender, the second slightly longer than the third, 

 not thickened, terminal joints slightly dilated ; thorax one-half 

 broader than long, the sides straight, distinctly angulate before 

 the middle, the surface closely and strongly punctured, slightly 

 rugose, opaque, dark fulvous ; scutellum piceous ; elytra elongate, 

 slightly widened below the middle, the apex rounded, covering the 

 pygidium, the surface strongly punctured in closely approached 

 rows, which are getting much finer towards the apex, the suture 

 very narrowly inf uscate, the breast black ; legs flavous, the tibiae 

 in the male rather dilated at the apex, the first joint of the anterior 

 tarsi in the same sex greatly widened, the metatarsus of the 

 posterior legs half the length of the tibia ; the penis slender and 

 curved, the sides near the apical portion with a distinct margin, 

 the apex moderately pointed, preceded by an elongate cavity. 



Hah. Salisbury, Mashonaland (G. Marshall). 



This Longitarsus is so extremely closely allied to our £. luridus 

 that I at first identified it with this species, but a close examination 

 reveals some small but distinct and constant differences ; these 

 consist in the much longer basal joints of the antennae in the 

 present insect as well as the equally more elongate terminal 

 joints ; the male organ shows likewise differences in structure, 

 inasmuch as there is no medial constriction as is the case in 

 L. luridus, the sides also have a distinct thickened margin, and the 

 anterior cavity is longer and larger ; in all other respects the 

 species agrees with the last-named species. 



Aphthona ovati^jntstis, sp. n. 



Short and ovate, winged, piceous below, apical joints of the 

 antennae black ; head and thorax fulvous, impunctate ; elytra pale 

 testaceous, the suture blackish, the surface finely punctate-striate, 

 the striae widely placed, indistinct posteriorly. 



Length 1| millim. 



Head impunctate, fulvous, the frontal elevations narrowly 

 transverse, the carina strongly raised ; antennae long and slender, 

 black, the lower three joints flavous, the third joint but slightly 

 longer than the second, terminal joints elongate, scarcely 

 thickened ; thorax subquadrate, one-half broader than long, 

 convex, the sides straight, angulate before the middle, the disc 

 entirely impunctate, fulvous ; scutellum piceous ; elytra wider at 

 the base than the thorax, convex, narrowed towards the apex, the 

 surface very finely punctured in somewhat irregular, rather 

 distantly placed rows, which near the apex become obsolete, 

 the interstices with some still finer punctures, a row of
