OF WASHINGTON. 459 



1.6 mm. Body cylindrical, thick and smooth, normal. Green finely ob 

 scurely lined longitudinally with whitish green; a broad, diffuse subven- 

 tral red shade. Dorsal round black spots on joints 6 to 8 anteriorly. 

 Ends faintly tinted with reddish mottlings. /Tubercles minute, setae 

 short, dark. Venter slightly whitish. The reddish suffusion at the ends 

 increases with age, especially subventrally. The larva is exactly the color 

 of the young Ardisia stem. 



To this list Mrs. Slosson adds Diastictis particolor Hulst 

 and Paly as auriferaria Hulst. 



PYRALID^E. 



Margaronia infimalis Guen. The larvae were bred in 1890 

 on Melothriagrendula; none seen in 1900. (Description, Journ. 

 N. Y. Ent. Soc., March, 1901.) 



Margaronia quadristigmalis Guen. The larvae were not 

 uncommon on the Forestiera porulolsa, slightly webbing the 

 leaves together. (See also Howard and Lugger, Ins. Life, I, 

 22, 1888.) The egg shells were found on the backs of the leaves, 

 elliptical, flat, with very slight thickness, 9x4 mm., finely 

 roundedly reticulate. The earliest larvae observed were mining 

 in the leaves, the mine linear, wide but short, not over twice 

 the length of the larva and with a hole for the ejection of the 

 frass. Later they live between the leaves. The last four stages 

 were observed with very little change. Head broad, outstretched, 

 flatly, the lobes rounded, paraclypeal pieces reaching vertex ; 

 colorless, shaded with brown over the lobes ; mouth brown, 

 occelli black; width 1.5 mm. Cervical shield large, colorless. 

 Segments slightly moniliform, the thorax narrower than trie ab 

 domen, joint 5 wider, joints 12 and 13 tapering a little, last half 

 of joint 13 smaller. Anal feet outstretched, divergent ; the others 

 small, slender. Whitish and translucent, shining with a green 

 tint ; joints 12 and 13 faintly brownish reticulate to match the head. 

 A small black dot on joints 3 and 4 on the front side of tubercle 

 iib. Tubercles large, transparent ; i and ii in line, iv and v united, 

 normal. On thorax ia + ib, iia + iib, iv-f- v, the subventral ones 

 smaller. The mature larva varies from translucent green to 

 whitish with faint brown reticulations on the head. 



Margaronia flegia Cram. Mr. Kinzel sent me moths and 

 larvae that he had found on a cultivated bush of Thervetia. The 

 species is common at Key West. (See Can. Ent., XXXII, 117, 

 1900.) 



Margaronia sibillalis Walk. This larva was rather destruc 

 tive to the mulberry, though somewhat rare in the winter season ; 

 the mulberry trees having lost their leaves. The last three stages 

 only were observed with widths of head .9, 1.2 and 1.7 mm., and 

 no marked changes. (See Journ. N. Y. Ent. Soc., March, 1901.)
