new Cicindelidee from Mashunaland, 451 
to be more ovate and more convex, with the labrum 
nearly totally black. 
In general facies, this species approximates to M. poly- 
hirmoides, but the markings are different from those of 
any other Myrmecoptera known up to date.

M. formosa, sp. n. 
/Eneo-nigra, supra subnitida, capite strigoso, labro nigro, in 
medio albo-vittato ; prothorace subquadrato, antice posticeque 
constricto, disco utrinque elevato, transverse plicato ; elytris elon- 
gato-ovatis, uirinque quinque-costatis, costis undulatis, interstitiis 
secundo quartoque profunde-alveolatis, vitta basali alba medium 
disci utriusque attingente plagaque triangulari ad apicem posita 
albis. 
Bronze-black, moderately shining on the upper part, dark 
metallic-blue underneath ; head conspicuously strigose; labrum 
black, with a median whitish longitudinal band in both sexes ; pro- 
thorax nearly quadrate, narrowed in front and behind, with the 
disk raised on each side and plicate ; elytra gradually ampliated 
from the base to about. two-thirds of the length, convex, ending in 
two moderately long apical spines, longer and sharper in the male 
than in the female, each elytron with five coste, the first and second 
near the suture very wavy, and reaching from the base to two- 
thirds of the length, the third costa equally long, while the fourth 
and fifth extend further, reaching to three-fourths of the length ; 
the intervals between the suture and the first costa and those 
between the second and fifth are broadly plicate, that between the 
first and second costs divided into six or seven broad, deep fovez, 
and the space between the fifth costa and the outer margin also 
broadly foveate ; in the fourth interval runs a basal yellowish-white 
band, reaching about the median part of the disk, and there is a 
supra-apical, more or less triangular, broad patch of the same 
colour, placed below the fourth and fifth costs; legs very dark 
blue. Length, 18-20; width, 5-7 mm. 
Allied to M. mauchi, Bates, but differentiated by the 
broad and deep fovezw in the second interval on the 
elytra; the dorsal longitudinal white band is longer in 
proportion, and the apical one more broadly triangular,
