from decumbent hairs next the eyes ; antennae yellowish with a darker

FAMILY MUSCIDiE. 



444. MuscA CADAVERUM Kivby. — Length of body 4^ lines. A 

 single specimen taken in Lat. 65°. 



Body black, with black hairs and bristles. Antennae plumate ; eyes 

 brown ; the cheeks and front in certain lights appear hoary or silvery from 

 inconspicuous down, in others black ; feelers subferruginous ; trunk and 

 abdomen black-blue with a greenish tint ; wings hyahne ; intermediate 

 areolet obtusangular ; winglets white, bordered with a testaceous nervure. 



This species approaches very near to M. cadaverina, but the front, 

 winglets and palpi are of a different color.

[317.] Body black, with black hairs and bristles. Eyes brown ; • 

 cheek and front ferruginous, in certain lights exhibiting something of a

 with three very indistinct black dorsal stripes ; wings hyaline, with the 

 intermediate areolet projecting internally into an acute angle ; winglets 

 white terminated by a white nervure ; abdomen heart-shaped, glossy, blue 

 with a slight tint of green.

 which it differs chiefly in having three obsolete black stripes between the 

 wings \ in the anterior spiracles not being of a different color from the 

 rest of the trunk ; in having white winglets and not black edged with
