most nearly like laticmerea ; but in brightness of maculation it 

 equals tepid a. 



The antennae of the male are practically like those of antennata. 

 The thoracic vestiture is mostly flattened hairs, the anterior crest 

 low, but in perfect specimens a little divided. Abdomen without 

 obvious dorsal tufts in any of fhe examples before me. 



Xylina tepida Grote.

Head, thorax and primaries bright, pale bluish gray. Head with a whitish 

 admixture in most cases, and with a smoky frontal line. Collar usually paler 

 below, a black line just below the tip, surmounting a vague reddish shading. 

 Thoracic vestiture flattened hair and scales, anterior crest very obscure, not 

 divided in any example before me. Abdomen mouse-gray, with a reddish tinge, 

 without obvious dorsal tuftings. Primaries with the markings brightly defined. 

 A distinct black basal mark, curved to meet the geminate basal line, sujieriorly 

 margined by reddish scales, above which is a white line from whi(!h a whitish 

 shade tends to fill the included space to costa. T. a. line geminate, blackflh, 

 inner portion a little diffuse, nearly upright, a little outcurved in the interspaces, 

 sometimes considerably below the internal vein. T. p. line geminate, broken, 

 lunulate or crenulate, incomplete and obscurely marked, outcurved over the cell, 

 abruptly drawn in so as to almost touch the inferior part of the reniforra, then 

 straight or nearly so to the inner margin. S. t. line pale, broken, a little irregu- 

 lar, preceded by contiguous blackish spots. A series of distinct, lunate, black 

 terminal spots. Median shade blackish, broad, a little diffuse, obvious in all 

 and prominent in most specimens, a little outwardly oblique, direct from costa 

 close to reniform and the t. p. line below it to the inner margin. Claviform 

 broad, concolorous, outlined in blackish, varying in length, but never extending 

 to the centre of the median space. Orbicular complete, narrow, irregularly 

 lunate, with the convexity inward, narrowly defined by black scales, broadly 

 annulate in white, the centre narrowly gray. Reniform large, almost as broad 

 as long, almost rectangular, with the corners rounded, narrowly defined by black 

 and black scales, inwardly obscured by the median shade, centrally flushed with 

 reddish. Secondaries smoky, with a carmine flush, the fringes a little paler. 

 Beneath reddish gray, powdery, primaries with disc smoky, secondaries with an 

 exterior dusky line, all wings with a dark di.scal spot. 



Expands 36-42 mm. = 1.44-1.68 inches. 



Hab. — Canada ; New England States ; New York ; Northern 

 Pennsylvania. 



Eiglit examples, six of them males, are at present before me. 

 These is a little difference in the relative brightness of the macula- 

 tion, but nothing else of note. The form of the orbicular here is 

 constant and characteristic, the broad white annulus forming one 

 of the most obviously contrasting marks. The antenuie in the 

 male are not much thicker or more lengthily ciliated than in the 

 female.
