in apical half, ten to eleven in number in the outer series. Extremity 

 of male abdomen a little clavate, a little upturned, the supraanal plate 

 long triangular, the sides bent a little beyond the middle, before which 

 they are broadly elevated a little, the apex acutangulate, the surface 

 more than usually plane, the median sulcus slight and hardly percepti- 

 ble except apically; furcula consisting of a pair of large, broad, greatly 

 flattened, parallel, strongly and rather regularly tapering and acumin- 

 ate fingers, reaching more than halfway across the supraanal plate; 

 cerci elongate, compressed, rather slender, subequal laminae, a little 

 obliquely vertical at the base, in the middle bent abruptly inward and 

 then at once again backward, but here completely vertical by a slight 

 twist in the bend, the apex roundly truncate, the basal half gradually 

 tnpering and beyond again enlarging to somewhat less than the basal 

 width, the whole extending to the tip of the supraanal plate; infracer- 

 cal plates broad and subtruncate apically, just shorter than the supra- 

 anal plate; subgenital plate broad, but a little longer than broad, 

 flaring, the apical margin scarcely elevated, thickened, entire, as viewed 

 from above strongly rounded. 



Length of body, male, 21.5 mm., female, 23.5 mm.; antennae, male, 

 9.5 mm., female, 9 mm.; tegrnina, male, 17 mm., female, 19 mm.; hind 

 femora, male, 11.5 mm., female, 14.5 mm.

 This species is certainly very closely allied in structure to the next, 

 M. cinereus, and may prove to be a variety of it, found in different sta- 

 tions. It wholly lacks, however, the cinereous speckling so characteris- 

 tic of typical examples of the latter species, with the rusty hue of the 

 pronotum. 



Some individuals are much smaller than, hardly more than half as 

 large as, others; the measurements are taken from the larger and appar- 

 ently commoner forms.
