Hub. — Atlantic States; Oregon (Corvallis); Washington Terri- 

 tory (Seattle) ; Texas (Fedora). 



This is one of our well known Tineids. Its resemblance to rusti- 

 cella is superficial ; at once distinguished by the hindwings having 

 all veins free, while veins 5 and 6 are stemmed in rusticella. The 

 type of the species, in excellent condition, is in the Clemens' collec- 

 tion at the Academy of Natural Sciences, Philadelphia. 



M. inargiiiitttrigella Cham. — Dyar's List, 572, No. 6511. — Palpi sordid 

 pale yellowish, labials brownish externally, except the apex of third joint. Head 

 yellowish; antennae dark brown above, fuscous beneath. Thorax dark velvety 

 brown. Forewings dark brown, intermixed with silvery white, and pale yellow- 

 ish white scales; the white scales prevail along the entire costal and free dorsal 

 margin, forming short, transverse strigulations upon the latter; immediately 

 before the middle of costal margin they form a large, ill-defined patch, traversed 

 by an irregular dark brown oblique streak which reaches to the vitreous spot, 

 beyond this patch are. three oblique streaks, and before it one distinct and a num- 

 ber of smaller spots, separated by white; a pale patch at beginning of dorsal cilia 

 containing on the margin a small black dot. Cilia pale yellowish, with three 

 darker dividing lines, three dark bars in the costal and irregularly streaked and 

 spotted in the dorsal portion. Hindwings grayish white, dusted with fuscous 

 towards the apex and having a slight brassy lustre. Abdomen above brown, 

 intermixed with gray. Underside of abdomen and legs silvery white, tinged 

 with yellowish; legs conspicuously spotted with dark brown. 



Exp. 11.0-13.0 mm. ; 0.44-0.52 inch. 



Hab. — Kentucky (Chambers); Pennsylvania (Hazleton) ; New 

 Jersey (Montclair, Kearfott) ; Louisiana (Vowells, Mills) 



The above description varies somewhat from that given by Cham- 

 bers, which, to me at least, made the recognition of this species with 

 a shadow of certainty, very difficult if not impossible, but having 

 carefully studied and compared the type with specimens in my col- 

 lection, the authenticity is fully established. Instead of the white 

 sputs along the entire costal margin, as stated by Chambers, it is 

 the dark oblique streaks which are more conspicuous. The pale 

 lines in the costal cilia extend in some specimens into the wing- 

 proper. 



H. monacliella Hb.— Dyar's List, p. 530, No. 6490. 

 Mr. Meyrick gives the following description : 



"Head and thorax white. Forewings less narrow, dark ferruginous fuscous, 

 with numerous small dark ashy fuscous spots ; an ochreous white trapezoidal 

 blotch, extending along costa from before middle to near apex and reaching half 

 across wing, lower side sinuate; a subhyaline spot in lower anterior angle of this. 

 Hindwings brassy gray, darker posteriorly. Exp. 11-17 mm."
