ance of the thorax and the relative positions of the cross-veins, as shown 

 in figure. When viewed under the microscope in some lights there 

 will be ' seen four grey thoracic stripes which are also characteristic, 

 especially when the thorax is rubbed. No males were unfortunately 

 sent. All the specimens were taken from beds of reeds close to the low 

 marshy shore of Lake Simcoe. I should not be surprised if this proved 

 to be Wiedemann's An, ferruginosus from New Orleans." Length of 

 body, 5*5 to 6 inm., with proboscis, 10 mm. ; of wings, 5'5 ; of hind legs, 

 12 mm. 



Habitat. — Lake Simcoe, Ontario, Canada (K. M. Walker).

Plate xi, lig. 3, Wing of ? . 



Wing unspotted, uniformly sooty-scaled. Legs and tarsi 

 unit'ornily black except the cases of the tibiae, \Yhich are dull 

 yellowish-brown. Thorax with a tun-shaped patch of greyish- 

 brown with two bare sub-median lines. Abdomen sooty, nude, 

 but for some brownish hairs. 



Head black, with densely packed yellowish forked scales, and a fairly 

 fuU frontal tuft. Papi and proboscis uniformly' sooty, otherwise is 

 almost indistinguishable from An, bifurcatns, but this is a distinctly 

 darker species, witli the middle of the niesonotum more frosty-cinereous 

 than it, and the wings are more densely scaled. Length. — 4 to 5 mm. 



Habitat. — Nortliern Europe and North America. In England it has 

 been taken at Penzance ; it also occurs in Scotland, and a few were 

 taken by ]\Ir. Theobald in North Wales.

 species have been received from Lieut. Gleu Liston, I. M.S. : —

 Wings, with three small interruptions on the black costa, in addition to a 

 large apical spot, and two basal dots ; bases of the fork-cells, and a spot on 

 III, between them, white, and there is also a largo triangular spot on II, 

 III, IV, and V, opposite the cross veins ; VI, with one long white interrup- 

 tion ; internal friugo dark, with broad white intervals at all but the sixth 

 longitudinal junction. Legs dark brown, with yellowish apical spots on the 

 tibiae aud fimoia, and on all but the last tarsal joints. Thorax dark- 

 grounded, clothed with white scales, so arranged as to show median, and
