IDENTIFICATION OF 



THE NOTODOXTIAN GENUS SCHIZURA 

 OF DOUBLEDAY. 



BY ALPHEUS SPRING PACKARD, PROVIDENCE, R. I. 



In The entomologisl for Feb. 1S41, 

 Edward Doubleday, in an article en- 

 titled, ''Characters of three new genera 

 oi 7iotodotitidae from North America," 

 describes and figures Schizura ipom- 

 eae giving the generic and specific char- 

 acters in some detail, and illustrating, 

 in a plate facing p. 60, the larva and 

 pupa from manuscript drawings by 

 John Abbot. 



When preparing the manuscript of a 

 monograph of the bombycldae, which 

 was published in abstract under the 

 name, "Synopsis of the bofjibycidae of 

 the United States" (Proc. Entom. soc. 

 Phil., J864, V. 3, p. 97-130, 331-396), 

 I was unable with certainty to identify 

 the genus (the species not then being 

 known to occur north of Florida), but 

 placed it next to my genus Coelodasys. 

 In 1S55 Walker referred it to Hetcro- 

 cainpa ; but neither Mr. Grote nor Mr. 

 H. Edwards have been able to identify 

 it. While looking over, during tiie 

 past winter, the volume of manuscript 

 colored drawings by John Abbot, in 

 the library of the Boston society of 

 natural history, I found the original 

 colored drawing, copied by Doubleday 

 and described b}' him as the larva of 

 Schizitra ipomeae. The larva figured 

 by Abbot I recognized as that of Coe- 

 lodasys bigitttatzis Pack, which I reared 

 last summer in all its stages from eggs 



kindly sent me by Miss Emily A. Mor- 

 ton, of New burgh, N. Y. 



On comparing my specimen of C. 

 biguttattis v/ith Doubleday's descrip- 

 tion both of the generic and specific 

 characters, it agrees exactly, and leaves 

 no doubt but that my genus Coelodasys 

 is a synonym of Doubleday's Schizura. 

 Hence the former name should be 

 dropped and that of Schiztira retained, 

 and C. biguttatus should, with little 

 doubt, be regarded as a synonym of S. 

 ipo7neae. Of Coelodasys I described 

 also C. edmafzdsii and C. harrisii^ 

 besides referring Notodonta unicornis 

 to it. My C. cinereofrons^ as previous- 

 ly shown by Grote, is a melanitic 

 variety of C. biguttatus. All these 

 species which are valid should, then, 

 be referred to Schizura. 



I tnay also add that I have identified 

 Doubleday's Heterccai)ipa astarte^ as 

 Grote had previously done : the larva 

 is represented by Doubleday's fig. i, 

 the pupa by his fig. 3. His Lochmaeus 

 ?na?tteo I have also readily identified ; 

 Grote's Heterocampa subalbicans is a 

 synonym of it. Doubleday's unnamed 

 larva, figs. 3 and 5, is that of Walker's 

 Cecrita gtittivitta^ referred by Grote 

 so Heterocainpa., and which I have 

 teen in its early and imago stages in 

 Prof. Riley's collection, having also 

 collected the caterpillar mjself either 

 in Rhode Island or Maine.
