PSYCHE. 



213 



inches in lengtli. Tlie granules had dis- 

 appeared, leaving only minute spots of 

 brown paler than the body. Tlie tliird and 

 fourth segments were still so little enlarged 

 as to be noticed only by an entomologist. 

 All the other marks were as before. 



July i2th. — The larvae grew to look dusty 

 on the back, and stopped eating. 



yuly iji/i. — Pupated. Pupa one and one- 

 half inches long, neither .stout nor slender; 

 very dark brown, and coffee-colored between 

 the abdominal segments. Segments honey- 

 combed ; wing covers slightly rough ; eye 

 covers well defined. There was a slight 

 pointed tubercle at the base of each antenna, 

 close to the eye. Anal hook long, slender, 

 with a bifid tip. 



The second larva differed from this de- 

 scription in having much clearer and darker 

 markings, and in being a trifle sinaller. In 

 the last moult it was at fiist bright green 

 with dark green markings, but became 

 brown twenty-four hours later. This one 

 also spun a few threads fastening a leaf to the 

 tin, while the first one did not spin at all. 

 The pupa was a trifle smaller than the first 

 one, and on January 14th, 1895, at 2 p.m., 

 gave a fine $ Amfhion nessus. 



RHOPALOMERA XANTHOPS, sp. nov. 



BY S. W. WILLISTON, LAWRENCE, KANS. 



(J, 9. Face wholly liglit yellow, with 

 a small rounded tubercle near the middle. 

 Palpi yellow, blackisli at the proxiinal 

 extremity. Antennae reddish yellow, the 

 first two joints largely, and the third on 

 the upper border, blackish. Front yellow, 

 black or blackish on the anterior margin; 

 no lateral frontal bristles; a pair of minute 

 proclinate ocellar bristles present. Meso- 

 notum reddish brown; when seen from in 

 front with two distinct stripes reaching from 

 the anterior border to about midway on the 

 scutellum; a less distinct, median stripe, 

 a narrow stripe on either side behind the 



suture, and the lateral margins in front, 

 all opaque light yellow. Pleurae pitchy 

 brown, mostly shining; a single meso- 

 pleural bristle present. Scutellum gently 

 sulcate above, the distal half shining 

 mahogany-colored. Abdomen black or deep 

 reddish black; second, third, fourth and 

 fifth segments each with the sides silvery 

 white; between these spots there are two 

 rows of similarly colored spots, becoming 

 successively smaller, those of the second 

 segment more or less coalescent with the 

 lateral ones. Hypopygium black or pitchy 

 black, shining. Legs pitchy black, the 

 upper part of the femora more reddish ; 

 the immediate base of all the tibiae and 

 the first two joints of all the tarsi light 

 yellow; hind tibiae dilated and ciliated, 

 the row of bristles not verv stiong and not 

 implanted on tubercles. Wings strongly 

 tinged with brown, which is more intense 

 distally in front and about the cross-veins. 

 Length lo-ii mm. 



Ten specimens, Yucatan, G. F. Gaumerf 

 Coll. Univ. of Kans. It is possible that 

 this species may be identical with the 

 insufficiently described R. Jiaviceps of 

 Macquart, from New Grenada, but not 

 probable, as there are positive discrepancies 

 in the description of the head, thorax and 

 abdomen. In several specimens the face 

 is for the greater part blackish, probably 

 the result of desiccation. 



Entomological Notes. 



In a paper read to the K. bohm. gesell- 

 schaft der wissenschaften on November 23d 

 last, Dr. Anton Fritsch, of Prag, announced 

 the discovery in the Permian beds of Bohemia 

 of the larval cases of a caddis-fly. This is 

 the first indication of the existence of insects 

 with a complete metamorphosis in paleozoic 

 times, unless the doubtful fragments found 

 by Dathe in Silesian culm are to be regarded 

 as shards of beetles, or the passages found in 

 certain carbonilerous woods are to be credited
