hYloicus pinastri. 279 



most is quite narrow and darker in colour than in S. pinastri*. Undersurface 

 uniform brownish-grey, faint traces of a mesial band on secondaries. In 5. pinastri 

 the marginal part of primaries is a little paler and more ashen than the rest of 

 the wing ; in this species there is no perceptible change in the coloration. ? . 

 Expands 3fins. Head and body same as $ . Uppersurface of primaries same 

 colour as J , destitute of all markings save a faint apical line and the obscure 

 streaks in cells between the median nervules near the median nervure. Under- 

 surface uniform dull greyish-brown. Described from one <? and one ? . The 

 former was captured in Canada and was received by me from Mr. Reakirt ; the 



? I took sitting on a fence, near some pine woods a mile from Reading, Pa. 

 I have never seen any others. Both examples are in good condition, though the 



? is a little worn, they seem to me to be an intermediate form between sequoiae 

 and pinastri, though very close to the latter (Strecker). 



Strecker adds that he knows not if this species be a form 

 of H. pinasti-i, as he has "never seen an example of the latter destitute 

 of the broad brown transverse shades of the primaries ; but should 

 this be the case, it is an easy matter to re-anagramize the name 

 back to its original spelling, und alles ist wieder gut." He further 

 adds some rough descriptive notes of two larvae that he considers 

 belonged to this species. These read : " Not quite three inches 

 long, rather slender, head yellow, striped with red ; body reddish, 

 surrounded with many transverse fine black lines ; a brown stripe 

 on back from head to anal horn, this stripe lined with white on 

 both sides ; on the sides alternate bands or lines of green and 

 yellow, green predominating from head to last segment (save one) ; 

 caudal horn dark reddish-brown ; the first few spiracles white, the 

 others ringed with red and black ; from base of anal horn to end 

 of anal segment, a reddish brown dorsal line. Found in October, 

 crawling on the ground, among the dead pine leaves in the same 

 piece of wood as the above 2 was captured. " In our opinion, Strecker's 

 figure and the United States example in the British Museum collection 

 are, without doubt, referable to the grey form of H. pinastri with 

 well-developed lineolae and ill-developed transverse shades. What 

 is more remarkable is that it is exactly the same form as Butler's 

 asiaticus, with the exception that only two of the three normal 

 longitudinal lineolae of the forewings are developed in saniptri.

 the white markings on the body and the lateral black spots on the abdomen 

 wanting, the transverse bands on the primaries and the secondaries smoky-brown, 

 the two longitudinal black dashes on the primaries shorter and more linear.

Staudinger diagnoses this form (Cat., 3rded., p. 101) as "abdomine 

 fere non maculate" Leech unites \Proc. Zool. Soc. Lond., p. 588 (1888)] 

 Butler's caligineus with pinastri, observing : " In his identification 

 of the dark Japanese form of this species, Butler refers to the 

 absence of ' white markings on the body,' and ' lateral black spots 

 on the abdomen ' ; in my series of H. pinastri from Japan I find 

 that almost every specimen has the body paler where the white 

 markings should be, and dark patches along the sides are distinctly 



* In a specimen in the British Museum collection labelled " United States " 

 both these transverse shades are indicated, so that the absence of these bands cannot 

 be considered as characteristic of American examples.
