antenngB in both sexes, but Phragmatohia^ Spilosoma Isabella 

 and IIyphcmb'ia.f etc., have. The maxillaa of Eiidryas are not 

 much longer than the thorax, and the palpi are rather small 

 and short. The eyes, especially in the males, are large, as in 

 Callimor'plia^ etc. 



The posture of the larva of Eudryas when ai rest, is like 

 that of some of the Arctice^ e. g., Euclicetesegle^ and still more 

 apparently like that of Ayarista, which it resembles strikingly 

 in form and colorino;. 



In looking over Stephens' catalogue, and also that of Mr. 

 Curtis, some queries and doubts have occurred to me respect- 

 ing the arrangement of certain genera in these works. Why 

 are not G-astropacIia and Odonestis placed immediately after 

 Saturnia, rather than Lasiocampa and Uriogaster? Their 

 larvae are certainly more S])hinx-like, and therefore nearer to 

 Bomhyx mori than Clisocampa, etc. On the other hand why 

 do not Poecilocampa pojyuU and Cnethocampa lead to the Lipa- 

 ridce by their larvce ? Compare the caterpillar of P. pojndi with 

 Hypogymna dispar, and of 0. pUyocampa with Clidia geograph- 

 ical and see the close resemblance. These gentlemen seem to 

 have mistaken the place oi Pentliophera and Limacodes. P. 

 morio and detrita are clearly Liparidm ; the antennee, venation 

 'of their wings, and general appearance indicate it, and, more- 

 over, their caterpillars are described by Denis and SchiflPer- 

 miiller as having only six tubercles on each ring, whereas they 

 have ten or more. If Mr. Stephens had known our American 

 Limacodes (not all of them true Limacodes^ but allied to it), he 

 would not have hesitated to put this genus among the Notodon- 

 tians, and near Cerura. By thus settling the place of Lima- 

 codes^ we of course decide that of Psyche. P. graminella^ $ , 

 the only foreign species in my collection, resembles Limacodes 

 cippus closely in the venation and form of the wings ; but I 

 must also admit that in this respect it comes near to Penthop)hera 

 and Orgyia. However this may be, if Oiketicus and Psyche 

 stand together in one group, then this group must come between
