rest ; fore wings light fuscous gray, basal space blackish followed by an indeter- 

 minate broad cross-line somewhat angulated, which is followed by an indistinct 

 dark band often showing only on the outer edges, this band being wavy sinuous 

 and of the same width across the wing, and on its outer side almost touching the 

 black discal spot; an outer sinuous whitish line, often clear white on costal half, 

 angulated outward at vein 6, then an irregular inner sinus running outward to 

 an angle at vein 4, this angle almost reaching the edge of wing, thence the line 

 is wavy angulate, subparallel with edge of wing to inner margin ; this line is 

 edged within with a broad dark band which generally is evident only on lines 

 limiting edge and is sometimes faint and indeterminate, sometimes with black 

 dashes on veins 2, 3 and 4 ; outer space clouded below apex and a marginal line 

 of black dashes hardly broken ; hind wings light gray, darker towards base with 

 black discal spot: beneath lighter than above, the outer lines showing, the white 

 line much broader with whiiish apical spot; hind wings color as above with two 

 fine cross-lines, the inner straight across the wings, the outer rounded, scalloped. 



Havilah, Cal., two males, two females. From Hy. Edwards, No.

There is much difference in the two sexes, the males being much 

 more distinctly marked and lined, and especially with the outer white 

 line. 



H. cnrvilinea. n. sp. — Expands 28 mm. Palpi short, somewhat long scaled, 

 black and gray intermixed ; clypeus and thorax gray. Abdomen ochreous ; fore 

 wings dull clay white, a blackish even basal cross-baud scarcely curved, another 

 corresponding band on middle field evenly curved across wing, edged within by 

 a faint light tinge; outer field with a band distinct at costa, broken and indeter- 

 minate across wings, showing mostly as dark dashes on veins ; outer space dai'ker, 

 more broad apically, showing an included dentate line parallel with outer margin ; 

 marginal line black ; hind wings light clay fuscous with faint double median 

 cross-line; beneath much as above, but much fainter. 



Vancouver Island, British Columbia. 



H. COStiguttata n. sp. — Expands 25 mm. Palpi blackish gray ; front gray, 

 black below ; thorax light gray on extreme front, collar and posteriorly, with a 

 black band across between anterior half of base of fore wings. Abdomen white, 

 stained somewhat on antei'ior part of segments with fuscous. Wings white, 

 somewhat stained with fuscous ; fore wings with two subtriangular black spots 

 along costa, followed in each case by fine geminate wavy black lines limiting the 

 middle field, the course being much as in X. abrasnria H.-Sch., the veins on the 

 course of these lines somewhat marked with black dashes; outer field clouded, 

 faintly showing submarginal lighter scalhiped line; marginal line black, broken, 

 two spots between each of the veins; hind wings with faint median line, mar- 

 ginal line as on fore wings; beneath slightly darker, costal .spots indistinct, lines 

 indistinct, almost obsolete. 



California, from Hy. Edwards. In a2:)pearance very much like 

 Thamnonoma subcessuria Walk.
