in :ipi(jil half, ten to eleven in iiumbci in the outer series. Kxtreniity 

 of iiuile abdcinen a little chivate, a little upturned, the siipraanal plate 

 h)nj; trianjrular, the sides bent a little beyond the nii<ldle, before whi<'h 

 they are broadly elevated a little, the apex aeutanj^ulate, the surface 

 nu)re than usually plane, the median sulcus slifjht and hardly i)ercepti 

 ble except apically; furculaconaistinjr of a pairot lar{;e, broad, j;reatly 

 tlatteneil, parallel, strongly and rather rejjjularly taperinp: an<l acuniin 

 site linjjers, reaching nioie than halfway across the supraanal plate; 

 <*erci elonpite, conipresse*!, rather slender, subequal laminae, a little 

 ol)li(|uely vertical .it X\w base, in the mid<ile bent abruptly inward and 

 then at once again backwjud, but here complet*'Iy vertical by a slight 

 twist in the bend, the «i/ex i ♦uiidly truncate, tne basal half gradually 

 tapering 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, 

 Haring, the apical margin scarcely elevated, thicke^ied, entire, as viewed 

 from above strongly rounded.

This species is certainly very closely allied in stru(;ture to the next, 

 M. cinercus, and may i)rove to be a variety of it, found in different sta- 

 tions. It wholly lacks, however, the cinereous si)eckliiig so characteris- 

 tic of typical exam])les of the latter species, with the rusty hue of the 

 pnmotum. 



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. / .
