452 M. Louis Péringuey on descriptions of 
M. invicta, sp. n. 
/Eneo-nigra, supra-subnitida ; capite strigoso, labro nigro medio 
albo-vittato ; prothorace quadrato, antice posticeque constricto, 
disco utrinque elevato, transverse plicato ; elytris elongato-ovatis, 
quinque-costatis, interstitiis reticulatis linea basali medium disci 
haud attingente, plagaque supra-apicali lata in singulo elytro albis. 
Bronze-black, moderately shining on the upper side, underside 
and legs cyaneous-black; head strigose ; labrum black, with a 
median yellowish-white longitudinal band in both sexes ; prothorax 
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 acute spines, 
long in the male, short in the female, each elytron with five cost 
reaching from the base to two-thirds of the length, with the first 
and second a little shorter than the other three, and the intervals 
reticulate ; on the second costa runs a narrow white line, running 
from near the base to about one-third of the length, and behind, 
edging the dorsal costz and extending more or less diagonally 
from the outer margin to the inner costa, isa sinuate silvery patch ; 
this patch is generally broader in the ¢ than in the ¢?, and I have 
seen a g¢ example where it had disappeared altogether. Length, 
15-20 ; width, 5-6 mm. 
A near ally to M. mauchi, Bates, but half the size; the 
sculpture of the elytra is identical, but the costz are 
better defined ; the inner one is shorter than the others, 
the fourth and fifth unite towards the apex in the male, 
but seldom in the female, while in the ¢ of M. mauchi the 
first and fifth costee are the longest, and unite below the 
others, and the posterior patch in the last-named species 
is triangular, short, not transverse, nearer the apex, and 
below the fifth costa.

C. dolosa, sp. n. 
Elongata, nea, elytrorum lateribus cyaneis; capite strigoso, 
antennis subcompressis, foliatis; prothorace cylindrico, postice 
constricto, transverse plicato; elytris elongatis, postice leviter 
ampliatis, crebre profundeque punctatis, convexis, ad apicem 
utrinque bi-mucronatis, puncto humerali maculisque rotundatis 
supra marginem positis albis.
