M. crucicoUis, Lansb., except that I have seen uo specimens with 

 red markings. It is rather larger and broader, and the upper 

 surface is more glossy. The clypetis is rather more deeply notched 

 and less widened anteriorly, and the eyes are less prominent. The

bind angles of the protltorax are a little more prominent and the 

 posterior lobe rather more pronounced. The posterior margins of 

 the ventral segments of the male are decorated laterally with 

 narrow white bands, the inner ends of which expand and become 

 confluent. 



The sexes differ little except in coloration, in which there is no 

 similarity. The male is silky indigo-black with white markings, 

 consisting of two narrow longitudinal lines upon the head ; two 

 sinuous longitudinal lines, continuous from the anterior to the 

 posterior margin, at the middle of the prothorax, and a marginal 

 line on each side not reaching the hind border ; the anterior part 

 of the scutellum ; three or four spots near the lateral edge of each 

 elytron, a large sutural patch, an M-shaped mark behind the last, 

 and a small apical band upon each. The pygidium has a narrow 

 median white line. 



The female has two narrow yellow lines upon the head, and the 

 rest of the upper surface is covered with a tawny earthy matter 

 which is more or less denuded at the shoulders and on the costac of 

 the elytra, and usually leaves also two bare black spots on the 

 pygidium.
