A REVISION OF THi: DEI/JOII) .M0TFI8 —SMITH. 59 



Ground color a bluisli gray, varyini; townid clay yellow, and with 

 more or less abundant black powdcriuiis. Head an<l thorax concolorous. 

 Primaries vaiyinu' in shade, in the relative amount of powderings and 

 in the distinctness of the nuiculation. Basal line marked on the costa. 

 Transverse anterior line single, blackish, more or less outcurved, irregu- 

 lar, angulatcd or outcurved in the interspaces, rarely complete, aiul 

 often nu'rely traceable. Transverse ]>osterior line single, crcnulated, 

 as a whole <[uite evenly bisinuate, though varying in the direction of a 

 single ontcur\e over the cell, without a corresponding incurve on the 

 subnu'dian interspace. The line varies also in distincti\eness, and is 

 sometimes reduced to a scries of venular dots. Subterminal line always 

 distinct, often prominent, yellowish, even, a little outwardly bent below 

 the middle, preceded by a more or less distinct, often i)r<»minent, l)lack- 

 ish or brown shading and followed by a similar but less prominent, 

 often obsolete, dusky shading which sometimes darkens the entire ter- 

 minal space. 



A series of venular black terminal <lots. A rigid or somewhat sinu- 

 ate, broad, dark or bhudcish median shade band obliquely crosses the 

 outer part of the median space, involving the reniform. Orbicular 

 punctiibrin, small, varying from yellow to blaid^. Reniform varying 

 from a narrow yellow lunule to a prominent bhick kidney-shaped S})ot 

 of moderate size. When the mark is yellow it incloses a small black 

 dot interiorly. Secondaries paler, often a dirty whitish gray or yellow, 

 with a vague dusky lunule, a fairly marked dusky median line, a pale 

 subterminal line often marked by darker preceding or following shades, 

 and a series of more or less evident dark or blackish terminal spots. 

 Beneath, varying from luteous to smoky, more or less powdery, with a 

 dark discal lunule, a dusky median line, and a pale sul)terminal line. 

 All these features are variable; in the pale specimens the median line 

 is best marked and the subteimiiml pale line is often obscure; while in 

 dark specimens the pale, often yellow, subterminal line is prominent, 

 and the median line is wanting on one or both wings. 



Expanse of wings, 2o to 30 mm. =1 to 1.20 inches. 



Habitat. — Canada to British Columbia, to Texas, to Arizona, Xew 

 Mexico, Colorado. Texas, in April, May, June; New York, June and 

 July; Delaware, Kansas, and Colorado, in June. 



The species is as common as it is widely distributed and as variable 

 as it is common. The difllerence in wing form between the sexes has 

 been alluded to, and in addition the females are usually more evenly 

 colored, with the onlinary maculation less evident than in the male. 

 The yellow sul)terminal line is the most prominent feature in most 

 instances and it is often sharply detined by distinct preceding and fol- 

 lowing dark shadings. The median lines are rarely prominent, and 

 not often completely detined. The transverse anterior varies in the 

 direction of obsolescence and in the amount of irregularity. The 

 transverse posterior varies from creiiulate to a series of venular dots.
