and am convinced that you and Westwood are correct in ap- 

 proximating it to these insects. Whether it be strictly con- 

 generical with them can only be ascertamed to a certainty by 

 comparing the larvae, when that of Epimenis shall be discovered. 

 The larva of Eudryas grata (^Cyphocampa grata im, from xu^oc, 

 incurvus) were abundant on my grape-vines during the sum- 

 mer of 1836, and I obtained several fine moths from larvae 

 which transformed in pots. They live solitary, and enter the 

 earth to change, without making a cocoon. The position of 

 the larva in repose, with its head depressed, and the third and 

 fourth segments arched upwards, giving it a hunch-backed 

 appearance, suggested the name of Cyphocampa; which, how- 

 ever, must now yield to that of Eudryas^ proposed by Boisduval. 

 The attitude, disposition of the colors, and even the habitat, 

 being similar to those of the larva of Alypia octomacidata (see 

 Smith-Abbot for the latter) probably led Boisduval to place 

 Eudryas among the Sphinges adseitce, in his Histoire Naturelle 

 des Lepidopteres. The simple setaceous antennas, and the 

 double stigmas on the wings of Eudryas, forbid our associating 

 it with these Sphinges. The larva of E. grata exhibits no 

 irregularity in its gait, but creeps with a uniform even motion, 

 its legs being sixteen in number, and the prolegs all of an equal 

 length ; so that in this respect it does not approach any of the 

 half-looping Noctum, although it may possibly find a place near 

 them if it does not belong to the Notodontiadce, where, at pres- 

 ent, I am disposed to leave it, as in my catalogue. The wings 

 of the moth in repose are like those of Orgyia. The palpi are 

 horizontal, not at all compressed, and the joints are nearly cylin- 

 drical, which also remove this insect from the Noctuw. 



Westwood's name recalls to my mind some facts stated in his 

 useful " Introduction," which, as I can confirm them, I will now 

 mention, lest they should again escape my recollection. On 

 page 68, Mr. Westwood says that " Lequien's figure of the 

 larva of Anthia sexguttata does not belong to the Carahidoi^ 

 and that it approaches much nearer to the larvas of the Elate'
