ments are bordered externally with a slender reddish line. Lateral fold 

 marked as a white line. There is a reddish spot on the lateral fold on the 

 side of the fourth segment, and a larger one on the side of the sixth seg- 

 ment. A little reddish dot at the origin of the hindmost of the true legs, 

 and another at the origin of the hindmost abdominal proleg. The anal 

 prolegs are tinged with brownish red on the inside, and they are long and 

 very slender, and apparently without claws. There is a short, brownish, 

 longitudinal line on the top of the anal segment. Head oval, pale brown, 

 mottled with dark. Body green beneath. No tubercles or horns on the 

 head, or on the first segment. Tail not raised in repose. The whitish lat- 

 eral line is slender but very distinct, especially on the last two or three 

 segments, being immediately below the spiracles. 



Eudryas grata Fabr. 



Larva on the grape vine in August and Sept., entirely naked, pale sky 

 blue; the head, a transverse band on each segment, except the last, which 

 has two, anal valve and all the feet orange colored ; head, bands and feet 

 spotted with black, and on each segment six narrow, transverse lines, two of 

 which are contiguous to the band on each side. When at rest this catei'- 

 pillar elevates the third and fourth segments very much, and depresses the 

 head. There is an obtuse prominence or elevation of the anterior part of 

 the eleventh segment, Avhich is visible at all times. Eats the leaves of the 

 grape vine, devouring the whole of the leaf from its tip and edges inwards, 

 veins and all ; commonly lives on the under side of the leaf Found abun- 

 dant Aug. 10, 1838. 



These larva? may be compared with those of CucuUia, which are banded 

 with yellow, and dotted with black on the head as well as on the rings. See 

 the figures of C. Lyclinitis and others .

 . An allied species is figured in the first volume of Dr. Boisduval's Species 

 des Le])idopteres, under the name o^ Eudryas unio of Hiibner; but I do not 

 know by whom the genus was founded. 1 had formerly called it Cyplio- 

 campa. As this report may possibly fall into the hands of European ento- 

 mologists, it may be proper for me to make a few remarks explanatory of 

 my reasons for still following my Catalogue of the Insects of Massachusetts, 

 in placing Eudryas grata among the NolodorJiadic. Fabricius suggested 

 that Bomhyx Venutia (VetiuUa of Cramer) with Bombi/x grata, ought perhaps 

 to constitute a peculiar genus. The former is (lir i\ pe of Latreille's genus 

 jEffocera, one of the Agaristiada;, a flimily belonging to the Sphinx section of 

 the Lepidoptera. The antenna;, both in Agariata and yEgocera, are stated 

 by Latreille and others to be fusiform, that is, thickened in the middle and
