90 THE CANADIAN ENTOMOLOGIST. 
The following species differ from the true Zizea as follows: the an- 
tennae are shorter and thicker, with the joints shorter and arranged like a. 
series of cups placed in each other, and microscopically ciliated (or rather 
pubescent.) I have not thought it necessary to erect a new genus how- 
ever, as in other respects they agree with the true Zzvea. 
15. T. auropulvella. WN. sp. 
Snowy white ; outer surface of the second joint of the labial palpi 
brown ; antennae yellowish white; primaries very sparsely dusted with 
pale reddish or brownish golden, except in the apical portion, where the 
dusting is rather dense; it is also thicker near the base of the dorsal 
margin. A dark brown spot on the costa at the extreme base ; another 
larger one on the costa near the base; a smaller costal one just before 
the middle ; a large one just behind the middle reaching to the fold ; 
another small one before the ciliae and five or six other small ones 
extending around the apex at the beginning of the ciliae ; in some lights: 
these spots are distinctly golden brown. Alar ex. #3 inch. Kentucky. 
Taken in July resting upon the trunks of trees in forests. It is rather 
sluggish and does not easily take flight. 
16. T. fuscopulvella. N. sp. 
Snowy white; outer surface of the labial palpi dark brown; antennae 
sordid yellowish white ; thorax and primaries dusted irregularly with dark 
brown scales, the dusting sparse in some portions, but in others aggre- 
gated into small spots or patches, a small one of which is on the fold not 
far from the base ; two other larger ones about the middle and others in 
the apical half of the wing ; it also assumes the form of more or less 
distinct costal and dorsal streaks. Alar ex. 34 inch. Kentucky. 
17. TL. maculabella. WN. sp. 
Snowy white; maxillary and labial palpi brown, except the inner sur- 
face of the labial pair, which is white; antennae sordid yellowish white ; 
thorax and primaries snowy white, with large distinct dark brown spots 
which in some lights are golden brown; one of these spots is on the 
anterior margin of the thorax and one on each side before the apex ; 
primaries sparsely dusted with dark brown ; a dark brown costal spot at 
the extreme base and a larger one near the base ; another within the one 
last named on the fold; before the middle is an oblique irregular streak
