witli an iuteiTupted dark dorsal liue. Le^s yellow, anterior and middle 

 tibia and tarsi dusky outwardly. Primaries brownish black. A series 

 of four large white spots below the costal marjiin, the tirst basal, the 

 fourth apical. Below the second spot is another of usually smaller size. 

 Close to outer margin, and usually touching the aual angle, is a large, 

 somewhat triangular spot, which is interrupted b^'the nervures superi- 

 orly. This is the maculation of a dark, fully-marked specimen. It 

 varies in the spots becoming more or less confluent, and the course of 

 the dark bands then becomes evident ; described in the same manner 

 as are the preceding species ; the costal margin is dark nearly to the 

 apex. The internal margin is dark to the anal angle. The outer margin 

 is dark from the apex nearly to the anal angle. Both apex and anal 

 angle are usually left white. From the internal margin near the anal 

 angle a broad, quadrate, dark spot extends to the middle of the wing, 

 in the lower portion of which is usually a white spot. From the middle 

 of this runs a spur to the costa, and in slenderly marked specimens this 

 becomes the representative of the cross-band as found in contif/ua. 

 From the outer upper angle proceeds a band to the outer margin below 

 the apex, and thus the marginal white patch is inclosed and a long sub- 

 costal white patch reaching to the apex. This is divided by a spur 

 from the costa to the oblique band. The white disk is divided into two 

 patches by an oblique, slightly augulated band from inner margin to 

 costa, and this band is peculiar to the species and always present 

 though not always complete. An inward spur from the quadrate half 

 band along the median vein usually constricts the second spot, and 

 sometimes divides it. All these marks are indicated in all the speci- 

 mens, even in those m which the spots are most completely confluent. 

 Secondaries immaculate white, rarely with a blackish dot near aual 

 angle. Beneath white, with the maculation of primaries faintly repro- 

 duced.

This species, to a certain extent, combines the two types of markings 

 of lecontei and militaris ; both oblique bauds are present though some- 

 what modified, and the militaris band is most markqd. The basal band 

 is the specific peculiarity of the species. 



I have taken this species rather abundantly in the Catskills, and of 

 the specimens taken then all were of the one type. I have retained 

 enough to make a fine series combined with the Museum specimens. 



In this series of maculate forms the insects in my own collections very 

 fortunately supply the deficiencies in the Museum material, and together 

 these two form a very complete series. 



Lintner, in the Ent. Contr., iii, 1-13, described under the name lecontei 

 some specimens of this form, in which the secondaries of the male have 

 four brown submarginal spots in the 9 antl three in the $ . He also 

 describes a larva in the following terms: "Larva feeding on spearmint
