EULEPTUS ALBICORNIS. 



Head and prothorax dark green, not shining ; labrum, palpi, and 

 the four basal joints of antennas deeply infuscate, almost black, the 

 other joints white ; prothorax cordiform, longer than broad, not 

 aculeate • laterally in the middle and slightly sinuate above the 

 posterior angle, which is very sharp, and the posterior margin much 

 recurved ; elytra oblong, deeply sinuate behind, plane, narrowly 

 striate, opaque black, and less silky than the other species ; under 

 side piceous ; legs flavescent ; femora with a broad apical infuscate 

 band. Length 10 mm. ; width 3J- mm. 



Hah. Mozambique (Rikatla). 



EuLEPTUS GRACILIS. 



Head, prothorax, and elytra bottle-green ; subopaque ; labrum 

 nearly black ; palpi infuscate ; antennae very long, reaching beyond 

 the median part of the elytra, the three basal joints rufescent, the 

 others deeply infuscate ; prothorax elongate, cordiform, a little 

 aculeate laterally in the median part, sinuate behind with the 

 posterior angle moderately sharp, and the posterior outer margin not 

 much recurved, disk plicate transversely ; elytra elongato-ovate, finely 

 striate, with the intervals less plane than in the other species, very 

 finely aciculate and faintly silky ; under side piceous ; legs 

 flavescent, femora broadly infuscate at the tip. Length T-J mm. ; 

 width 2-J mm. 



Hah. Mozambique (Rikatla). 



Gen. ENOICUS. 



Mentum with a long median tooth slightly truncate at the tip ; 

 ligula dilated at tip and nearly truncate ; paraglossae as broad as the 

 ligula, disunited from near the tip only and a little longer ; palpi, 

 antennas, and head of Platyiius ; prothorax attenuated laterally in 

 the anterior and posterior part ; elytra elongato-ovate, third interval 

 without any puncture ; first and second joints of anterior tarsi 

 slightly grooved, intermediate and posterior ones distinctly so ; the 

 anterior tarsi of the male as in Platynus, fourth joint deeply incised, 

 almost bilobate. 



The distinctive characters of this genus consist in the peculiar 

 shape of the prothorax very different from that of any South 

 African Platynus, and in the absence of punctures on the third interval 

 of the elytra. As iridescent as Melanodes of the tribe Chlcenides, 

 and with a ligula and paraglossae nearly similar in shape, it is at 

 once differentiated by the more slender antennae as well as by the 

 groove on the intermediate and posterior tarsi ; the general facies is 

 also less massive.
