Hydriomena speciosata Pack. 



(a) Agassizi, nov. var. 

 Expanse, 38 mm. 



Packard, in his original description (Proc. Boston Soc. Nat. Hist., 

 XVI, p. 22, 1874), had two males of different colour and markings. Tlie 

 one from which most of his description was drawn was a pale pea green 

 form, wholly different from the black margined form, which I shall 

 call the variety, limiting the other as type. In Agassizi the palpi are long 

 and slender. Fore wings : basal band black, then a whitish-green space to 

 first line of mesial band, which is narrow, black and angulated on median 

 vein, followed by a narrow whitish-green band and then a wide dark 

 band or y band, which is twice as broad as in speciosata^ almost 3 mm. 

 I'hird line broken just below costa, where it is whitish-green, then begins 

 black on median vein, below which are two whitish-green spots. Extra 

 discal line black and same as in speciosata^ mesial space so narrow as to be 

 practically absent. Beyond extradiscal line is a broad irregular greenish- 

 white band running to inner margin; beyond this the wing is entirely black 

 except at apex, where there is a green apical streak and two yellow-green 

 spots at centre of outer border. 



Beneath fore wings brown and yellow, the bands of above showing 

 through, but broader than in speciosata, in which also the black outer 

 border is absent. 



This variety was noted by Packard in the original description in the 

 last three lines, and again in the monograph. It is very distinct, and can 

 be recognized by the broad mesial y band and the black outer margin, which 

 is pea green in speciosata. It is a colour variety of speciosata, and I shall 

 explain its position in my revision, which I cannot complete as yet, as I 

 have to return at once some of the types, which were kindly loaned me, and 

 do not permit of delay. I shall explain all other varieties to follow in my 

 revision.
