fused, whereby the distinct spots and blotches of the typical 

 form become more or less obliterated. Discal spot and two 

 at end of cell distinct, a small spot of the pale yellow ground 

 color immediately before the lower spot at end of cell. Two 

 of the specimens — Mr. Kearfott's — have the dusting less dif- 

 fused, in fact are lighter than typical specimens. The wings 

 in this variety appears to be relatively narrower than in the 

 former. It may prove a distinct species. Expansion 13.0- 

 15.0 mm., 0.52-0.6 inch. 



Var. fumerella. 



Differs from the typical form by its general dark colora- 

 tion. Head, basal joint of antennae, palpi and thorax sordid, 

 grayish-ochreous, dusted and speckled more or less densely 

 with fuscous. Forewings grayish-fuscous ; markings as in 

 the typical form. The ground color in some specimens has 

 a slight ochreous tinge. Expanse 17.0-18.5 mm., 0.68-0.74 

 inch. 



Have bred this form likewise from the fruit racems of 

 sumach. It is distinctly larger in size than the typical form, 

 wings relatively broader. Rubbed or flown specimens might 

 be confounded with H. purpurocomella, but in the latter 

 species, aside from the absence of markings of forewings, 

 the head, thorax, antennas and palpi are grayish-fuscous. 



Var. quisquiliella Zell. 



Differs from the typical form by its more elongate and 

 pointed forewings, its relatively narrower hindwings ; dust- 

 ing of forewings the same, but more suffused ; appearance 

 of insect more gray with a pale yellowish tinge — possibly 

 due to fading : From minorella by its larger size, different 

 wing form and less diffused fuscous dusting. From fumer- 

 ella by its decidedly narrower wings, smaller size and paler 

 coloration. Expanse 17.0-18.0 mm., 0.68-0.72 inch. 



Hab— Tex. (Dallas). 



I have examined the type specimens in Cambridge Museum. 

 Three of these bear Zeller's green labels, number 1712 : — 

 Dallas, Texas Boll. In all of these veins 3 + 4 are stemmed, 

 5 arising out of the stem.
