strigose ; prothorax subcylindrical, broad, plicate transversely, and 

 having a median longitudinal glabrous groove more brassy than the 

 sides ; elytra elongato-ovate, convex, and ending in a short apical 

 sutural tooth on each side (female) ; they have on each side five 

 slightly wavy raised lines reaching from the base to three-fourths of 

 the length ; the intervals are deeply foveate, the fovea3 transverse 

 and reticulate ; the apical part is roughly shagreened ; on each side 

 there is on the basal part of the third interval a short, narrow, 

 yellowish band, and a posterior marginal white line running parallel 

 to the apical shagreened part, but not reaching the suture. 



Less elongate than M. Bcrtolonii, and with the prothorax a little 

 broader and more roughly plicate ; it is distinguished from it by the 

 reticulate fovese in the intervals of the elytra ; the posterior marginal 

 white band is similar, but M-. Bertolonii has no trace of the basal 

 dorsal yellowish white band, which is not, however, very distinctly 

 defined in M. dissepta. Male unknown. Length 21 mm. ; width 

 6 mm.

Black, moderately shining, with a bluish tinge on the head and 

 prothorax, elytra dark bronze; labrum black, with a median yellowish 

 white patch in the male, this patch being hardly distinct in the female ; 

 head conspicuously plicate ; prothorax cylindrical, longer than broad, 

 distinctly constricted in front and behind, and transversely plicate ; 

 elytra elongated, gradually ampliated from the base to about two- 

 thirds of the length, convex, the male with two long sutural spines, 

 the female without any and having on each side five long raised 

 lines, the outer two reaching from the base to about three-fourths 

 of the length, the three discoidal ones somewhat shorter, apical 

 part shagreened, intervals broadly foveate, the fovese with a golden 

 sheen, no supra-marginal white spot or band ; as a rule under 

 side and legs very dark blue. Length 17-19 mm. ; width 

 4^6 mm. 



Very closely allied to M. polyhirmoides, Bates ; the shape and size 

 are similar, but the elytra have no white markings. I have seen a 

 male caught in copula with a female of polyhirmoides, which my 

 correspondent informs me is very much rarer, but is found in the 

 same locality ; it is, however, possible that the said female may have 

 been a polyhirmoides without any white markings, for I have seen 

 a male of that species without the apical sutural patch, and with 

 the dorsal white line partly obliterated.
