 tudinally subquadrate or somewhat longer than broad (male) or trans-

 in J/. pacificus. Tegmina a little or considerably shorter than the prono- 

 tum, broad or very broad oval, attingent or subattiugent, well rounded 

 apically, usually half as long again as broad but sometimes little longer

 very obliquely bifasciate with blackish fuscous, the proximal fasciation 

 usually narrow, the distal broad, sometimes more or less suffused on 

 the outer face, the genicular arc black, the lower surface sanguineous, 

 though the outer half is sometimes flavous; hind tibiae very dark 

 bluish purple, sometimes dull dark glaucous and then with a broad, 

 subbasal, pallid annulation, the spines long, pallid at base, the apical 

 half or more black, ten to eleven, rarely nine, in number in the outer 

 series. Extremity of male abdomen clavate, strongly recurved, the 

 supraaual plate precisely as in M . pacificus ; furcula as there, but slightly 

 more prominent; cerci broad, somewhat rounded and tumid at base, 

 in the middle third tapering rapidly, the apical third subequal, very 

 slender, incurved and a little arcuate as seen from the side, the tip 

 bluntly pointed and almost attaining the tip of the supraanal plate,
