 manitoba, with which it agrees in size and general appearance, in having 

 the sexual dash on the forewings of the <? , slightly shorter and edged beneath 

 with a brown border as broad as itself, and in having the band on the under surface 

 of the hindwings formed of more closely connected spots. The apical superior tooth 

 of the lateral clasps of the anal appendages is very large, while the subapical tooth 

 is nearly aborted. Captured in California by H. Edwards (Scudder). 



Under the name of sylvanoides (Mem. Bost. Soc. Nat. Hist., 

 ii., p. 352), Scudder says that this insect is most nearly allied to 

 manitoba, smaller than comma, and differs from all the species of this 

 genus in that the discal dash upon the upper surface of the forewings 

 in the $ appears nearly twice as broad as usual, from the presence of 

 a patch of dark brown scales along its inferior surface ; the upper surface 

 of the forewing of the female also differs, he says, from that of any other 

 species in having a quadrate transparent spot in the lower median 

 interspace just below the last divarication of that nervure, and a partially 

 transparent triangular patch at the extreme base of the upper median 

 interspace ; these are not given with sufficient distinctness in the 

 plate ; besides the three little yellowish subapical patches lying one 

 beneath the other next the costal margin, asmientioned by Boisduval, 

 there are two similar but squarer patches in the interspaces beyond 

 the cell and nearer the outer margin. The upper surface of the hind- 

 wmg of the male does not differ from its usual appearance in P. 

 manitoba ; that of the female is mostly dusky, with a tawny patch near 

 the base, and in the middle of the outer half of the wing a broad, 

 tawny, transverse patch double the breadth of the belt of the under 

 surface. Beneath, a silvery white ( $ ) or pale ( £ ) slender belt 

 of small quadrate spots, similar to that of P. comma, bent at a 

 little less than a right angle, the portion at right angles to the 

 inner border straight and continuous, the inner portion sometimes 

 broken, sometimes continuous and straight. Of the genital arma- 

 ture, the upper organ is strongly arched, deeply sulcate above 

 posteriorly; hook about one-third the length of the centrum (but in 

 the only male specimen at hand, broken, doubtless of the comma 

 type) ; lateral arms cylindrical, very slightly tapering, not very widely 

 separated at their base, beyond straight. Clasps about twice as long 

 as broad, not extending so far backward as the upper organ, narrowing 

 pretty regularly, the posterior border well rounded, scarcely extending 

 beyond the apical tooth, which is pretty large, erect, triangular, pointed 

 and separated, not widely ,*by a moderately deep, rounded excision, from 

 the preapical tooth ; this is but a slight, triangular, compressed 

 denticle, removed from the upper edge of the clasp, the height of 

 which it attains by a slight excision ; the lamina supporting the inner 

 anterior edge of the apical tooth is distinctly and sharply serrated, 

 terminating some distance in advance of the preapical tooth by a 

 serration twice as large as the others, and much larger than the pre- 

 apical tooth itself. This species has only been taken, and rarely, in 

 California (Scudder).
