Smaller than M.formicarius, browuisli; front entirely blackish- 

 brown ; occiput fawn coloured, spotted with brown, viz., two median 

 geminated linear spots in front, two quadrangular spots on each side 

 near the eyes, and two median linear geminated spots behind ; anten- 

 nae rather short, obscure reddish, paler at the base, the apex moderately 

 thickened ; mouth yellowish fawn coloured ; labial palpi longer than the 

 ]iiaxillary, the third joint strongly thickened, but slender at the tip ; 

 pro-thorax short, traversed by two channels, rounded in front, slightly 

 excised in the middle, yellowish fawn coloured, the middle broadly 

 brownish, with a brown line on the sides ; meso-thorax dark brown, 

 with a yellowish line on each side, and a point near the base of the 

 wings ; abdomen long, thin, dark brown, the basal half of each seg- 

 ment pale yellow, the yellow extending slightly on the apical margin of 

 the preceding segment ; the body scarcely hairy ; legs short, slender, 

 fawn coloured ; anterior tibiae faintly spotted with brown, the spurs on 

 these tibia? a little shorter than the first joint of the tarsi ; wings rather 

 long, narrow, slightly acute at the apex, hyaline, slightly greyish, the

Madeira. 



This species agrees, in its neuration and legs, with the group of 

 M. capensis of Eambur. This latter species is synonymous with M. 

 fasciatus of Burmeister, and perhaps also with M. alternans. The dif- 

 ference consists solely in the darker and more varied coloration of 

 M. capensis ; in the place of browTi there is black, with the palpi and 

 legs spotted with the same colour, and less yellow on the abdomen. It 

 is possible that these differences may be owing to the type of capensis 

 being more mature. It is not at all impossible that M. caninus, F., 

 from Guinea, may be identical with alternans.
