developed, a little longer thaii the terminal hair, testaceous. Surface 

 of the peristome and higher occiput without small black setae. The 

 somewhat short frons has 1 pair of long vertical inner crossed setae, 

 2 ocellary setae diverging in front, and on each side developed ascend- 

 ing frontal, 2 or 3 reduced trausfrontal, and 2 setae under the insertion 

 of the antennae. Thorax ashy yellow with the usual obscure bands : 

 3, sometimes 4 dc. ; st. = 2 + 1 ; pteropleural seta like the anterior 

 sternopleural. Scutellum partly rufous. Abdomen testaceous-yellow, 

 1st segment wholly black above, but only in front on the sides ; a black 

 medio-dorsal band, partly hidden by the light ashy down, runs across 

 the 2nd segment and expands in a triangle on the 4th segment, the 

 rest of the segment and the hypopygium being red. The 2nd segment 

 has no discal seta, the 3rd has a pair. Legs testaceous, marked on the 

 anterior face of the femora with a black spot at their insertion, and 

 with another near the knees assuming often the shape of a small baud ; 

 the tibiae are more or less darkened on the external side, the tarsi are 

 black. Claws and pulvilli hardly elongate. The colour of the legs 

 recalls that of M. affinis Cort.

 sectioned by transverse bauds having a black sheen ; end of last

 dull reddish. Abdomen moderately shining, testaceous red; 1st 

 segment black in the hollow ; 4th black in the two posterior thirds, 

 having a pruinose whitish band on the anterior, or sometimes of the 

 same colour as the other segments and black at the end only. A 

 medio-dorsal band, sometimes entire, sometimes stopping at the end of 

 the 2nd segment, sometimes also almost totally obliterated, unites or 

 tends to unite the two black extremities of the abdomen. Legs black
