Mybmecopteka limbata, BertoL, 

 Catal., p. 65. 



Having been able to examine several examples of this species 

 collected in Mozambique, I am led to the conclusion that M. 

 Saundersi, Chaud., is the male of M. limhata ; in some of the males 

 the subhumeral lateral dot on the elytra is slightly noticeable, while 

 it has become quite obliterated in others ; in the female this spot is 

 not quite obliterated, and in many cases it is very conspicuous ; the 

 dorsal patch is also smaller and rounder in the male than in the 

 female. 



Hah. Mozambique (Tembe). 



Myrmecopteka umfuliana. 



Black, with a slight geneous tinge on the upper part ; very dark 

 blue underneath ; elytra a little more opaque than the head and 

 prothorax ; labrum with a median longitudinal whitish band in the 

 male, totally black in the female ; head strigose ; prothorax sub- 

 cylindrical, longer than broad by one-fourth, deeply constricted 

 behind, thus making the discoidal part look much raised, plicate 

 transversely, broadly and deeply grooved longitudinally in the 

 middle, and with the groove filled with a dense white pubescence ; 

 elytra elongate and very little ampliate past the median part in the 

 male, and with a long sharp apical spine on each side of the suture, 

 elongato-ovate in the female, and with the apical part of the suture 

 nearly blunt ; they have on each side five raised, very slightly wavy 

 lines, the two discoidal ones of which reach to about two-thirds of 

 the length, while the juxta-sutural and the two outer ones are 

 produced a little further ; the intervals are foveate, the fovese deep 

 but narrow, and the apical part is roughly shagreened ; on each side 

 there is a narrow yellowish band running on the second costa from 

 the base to about fifth of the total length of the elytra, and an apical 

 marginal one, not broader than the dorsal one, and ascending from 

 the suture to about one-third of the length. 



In the female the alveolae of the intervals of the elytra are not so 

 deep as in the male. 



Allied to M. costata and M. Bcrtolonii ; it differs from the former 

 in the shape of the prothorax, which is much broader and also more 

 roughly plicate, while the intervals of the elytra are much less 

 deeply foveate than in the latter ; it is easily differentiated from both 

 by the basal dorsal white line. Length 20-21 mm. ; width 5-7 mm. 



Hah. Zambezia (Umfuli Eiver). 



Myrmecopteka dissepta. 

 Black with a faint a3neous tinge ; elytra shining ; under side and 

 legs very dark blue ; labrum entirely black in the female ; head
