from, but I believe it to have been from one of them. I am therefore 

 disposed to regard melinellus and dispersellus as varieties of the same 

 species. 



S. dispersellus, Robs. 



I have forty-seven females including the types, and three males of 

 this type before me. I was disposed to think at first that I had several 

 species but now conclude that they all belong to one very variable 

 species. The following description will cover the varieties before me. 

 Expanse of wings, 22 to 26 mm. in tlie males ; 25 to 38 mm. in the females. 

 Head, palpi, thorax and forewings testaceous in some spi-cimens and tawny in 

 others, more or less sprinkled with minute fuscous scales in some. A dark brown 

 discal dot rests on the lower angle of the cell and there is a terminal row of the same 

 color scarcely visible in some of the specimens. An oblique stripe of dark brown ex- 

 tends from near the apex down to or in the direction of a dot on the outer third of the 

 fold. A more or less prominent dark bnjwn stripe extends from the base of the wing 

 along the cell to the outer margin near the apex. Tins marking has every degree of 

 prominence, from a heavy stripe to complete obliteration. In some specimens the 

 costal portion of the wing above this stripe is yellowish white, much lighter than the 

 rest of the wing. This variety may be called albicostt'lhis. There is another dark 

 brown dot resting on the fold below the middle of the cirll. 



The hind wings are white, somewhat sordid or yellowish in some of the speci- 

 mens and there is a row of dark points quite prominent m some, scarcely visil)le in 

 others and entirely wanting in others. 



The abdomen and anal tuft are white, more or less sordid. The underside of the 

 hind wings is of the same color as above, and the fore wings are nearly of the same 

 color and showing to some extent the markings of the upperside. 



The males have the fore wings somewhat suffused with fuscous and tlie terminal 

 points are more pronounced on both the fore and hind wings. 

 The synonomy will be as follows : 

 SchcEnobius melinellus. 



Chilo Dielinelliis^ Clem. Proc. Phil. Ac. Sc. (i860). 

 Schcenobius melinellus, Robs. Lyo. N. H. of N. Y. (1870). 

 var. dispersellus. 



Schcenobius dispersellus, Robs. Lye. N. H. of N. Y. (1S70). 

 var. albicostellus. Fern. 



S. clemensellus, Robs. 



Robinson gave this name to the species called Chilo aquileUus by 

 Clemens, because the latter name was pre-occupied, and states that he 

 has recognized the insect and therefore appends the original description 

 which is as follows : 



" Dark fuscous. Fore wings with an ochreous streak along the sub-median 

 nervure and its nervules, and those beneath likewise touched with the same hue. 

 Hind wings yellowish fuscous." 



I have before me, belonging to the collection of the Am. Ent. Soc. , 

 a specimen on a short pin with a small label marked Chilo n, sp. .^ in 

 Dr. Clemens" hand-writing and also a large label in Robinson's hand-
