unaware of such a distinction, and his statements here and in the 

 American Naturalist (XVI., p. 173) may refer to either Henrici or irus. 



Holland mentions the rusty suffusion of the upper surface as one 

 point of distinction, and figures a well suffused 9 • This character is 

 thoroughly unreliable because inconstant, relative and balanced by 

 similar suffused individuals of irus. Nevertheless, it has been used as a 

 criterion by many, and there is a specimen in the collection of the late 

 J. A. Lintner labelled T. irus, var. Henrici, which is an undoubted ^ 

 irus. 



The characters, then, separating the two series seem to be of 

 sufficient importance to warrant their recognition as distinct species, at 

 least until the test of breeding can be applied. I have been unable to 

 discover any difference in the genitalia, but this fact hardly militates 

 against the position taken, as one needs a long series and a good 

 imagination to discriminate between the genitalia of any of the recognized 

 species of this genus. 



The earliest record of the capture in this vicinity of /. Henrici which 

 I have is May 28, 1890. 



A NEW SPECIES OF BUCCULATRIX. 



BY MARY E. I\I U R T F E L D T, K I R K W O O D, MO. 



Bucculatrix Ainslielia, n. sp.— Antennte about three fifths the length 

 of the fore wings, annulated in dusky brown and dull yellow. Eye caps 

 golden white, expanded. Apical tuft long, projecting forward, dark brown 

 in centre, shading outwardly to dingy white. Face satiny cream white. 

 Thorax cream white, more or less dusky, overlaid with dark brown scales, 

 with small but distinct dark brown spot on centre of dorsum, two rather 

 narrow marks of same colour forming a triangle or' open V on posterior 

 joint, back of which is a silvery white band. Forewings : ground colour 

 shining cream white, more or less obscured by dark brown scales, which 

 in some lights exhibit purplish reflections. The pattern, which, though less 

 deeply shaded in some specimens than in others, is quite unvarying, con- 

 sists of a dark brown longitudinal band from the base along the costa, 

 gradually broadening and intensifying to the apical third, where it narrows 

 and curves backward, leaving the anterior margin to the apex merely 

 speckled with the dark scales. The inner margin to beyond tiie middle is 

 but sparsely irrorate with brown, but has, just below the cell, a conspicu.
