size. The species recalls tlie figr.re of Heminiatia Hcortealla, Jjed. ; 

 but the wings are larger and it does not seem })ossible tliat Lederer 

 should have overlooked the strong generic characters (Lederer had 

 4 specimens of his species before him). The new species recalls in 

 its colors and appearance Mochlocera Zelleri ; it is distinguished at 

 once by the shape of the outer line and the less vivid coloration. 

 Basal field of the jirimaries black before the anterior line, shading to 

 blackish gray at base. This portion of the wing is bounded outwardly 

 by the even, nearly straight, concave anterior line which is, in the 

 male, indented subcostally, intruded upon by the discal pellucid 

 sexual spot. Median space gray, powdered Avith white ; this lighter 

 color extends narrowly beyond the blackish posterior line, which is 

 exserted over the median nervules, slightly irregular and situate 

 rather far from the margin. On the basal field are some raised 

 black scales on median and subcostal veins, and on median space 

 are raised patches of white scales enclosing black ones, not very 

 evident. The median shade is subobsolete, and inferiorl}^ shows a 

 very faint reddish tinge, not observable without attention. The 

 terminal space is dark fuscous, inconspicuously powdered with gray 

 scales. A terminal black interrupted line ; fringes fuscous, with an 

 inconspicuous pale line at base. Hind Avings fuscous, rather dark ; 

 fringes paler, finely interlined. Head and thorax dark gray ; abdo- 

 men fuscous. Beneath blackish fuscous, paler in the 5 ; a faint 

 darker outer transverse line in primaries. Expanse 26 mil. Habitat, 

 New York. Two fresh specimens. In the male the black portion 

 of the primary, before the anterior line, is more strongly contrasted 

 with the dark gray base than in the female, Avhere the wing seems 

 to shade gradually into lighter at the base. 



XOTE OX BLACK KNOT. 



Since the publication of the article on Black Knot, on page 13 

 of this volume. Prof. AV. G. Farlow writes that he has found the 

 Knot on the Beach plum (Prunus maritima) growing in Martha's 

 A^ineyard, and also on the rum-cherry (Fninus serotina). This ex- 

 tends the number of our native wild trees and shrubs upon which 

 the Sphaeria morbosa, the fungus which causes Black Knot, has been 

 observed. 



A new variety of Pseudohazis Eglanterina.
