126 Twenty- FOURTH Report on tee State Museum. 



upon whicli it is placed ; the lamimse bear on theii' two sides two rows of 

 fine cilia, extending from a common point on the middle of their base 

 to the two outer angles, regularly increasing in length as thej recede 

 from the originating and divei'ging point, the rows sliglitly curving 

 toward one another and uniting at their tips. As seen from above, 

 the connivent cilia fringing the antennal stem, are alone visible, in 

 their greatest length nearly equaling the pectinations oi S. geTuinatus. 

 In this latter species, from the middle of each antennal joint, are 

 given out two broadly diverging, slender, curved, cylindrical, apically 

 rounded pectinations which are margined with short and fine cilia ; 

 the pectinations are thirty-nine or fort}^ in number. 



The apex of the primaries is acute in S. ojothalmifms as in 8. ocellatus 

 (excavated in S. geminatus), but less curved apically on the anterior 

 margin ; it is without the white-bordered semioval brown patch which 

 is a feature in gemmatus. The excavations of the hind margin 

 approach nearer to ocellatus than to geminatus. The posterior wings 

 are less developed costally than in either of the above two species. 

 The ocellated spot is quite ^ small, having a diameter between the 

 crescents of about one-half that of the thoracic spot (in the other two 

 the diameter exceeds that of the thoracic spot) ; it rests anteriorly on 

 the second median nervule, centers on the first, extends to midway 

 betw^een the latter and the submedian nervure, and is removed one- 

 half its longest diameter from the outer margin. It consists of a 

 black spot and two slender, subequal crescents almost uniting at their 

 tips, of which the anterior one is placed just within the anterior mar- 

 gin of the spot which is lost beneath tlie long, rose-colored basal hairs, 

 and the posterior one forms its posterior margin — the whole present- 

 ing a well defined ellipse, having its transverse diameter on the sub- 

 median nervure. From opposite the center of the spot interiorly, 

 disconnected from it by a brownish line, a short black dash points 

 toward the anal angle, but is merged in an ochreous-brow^n shade 

 running to the angle, and thence acutely reflected toward the base. 

 The thoracic spot is ochraceous-brown, straight in front, covering all 

 of the thorax except a white bordering to the gray tegulse. The colors 

 of the abdomen and wdngs diifer material^ from those of the two 

 species with which it is compared, for while they are characterized by 

 shades of deep brown, in this, the colors are fawn or pale ochraceous- 

 brown. Its expanse is two and six-tenths inches; length of body 

 one inch.
