Bombycidae, in imaginal structure; the larva of Oeratomia quadricor- 

 nis influenced by the near approach of the latter family simulates that 

 of Citheronia. 



Among the Noctuidae are Raphia /rater Grote, Eurois latex Gruenee, 

 sp., Gallopistria monetifera Guen. sp., Noctua O.-nigrum L., N. bicar- 

 nea Gruenee. Philogophora iris Guen.. Zj/lophasia lignicolora Guen., 

 Alaria gaurse A. & S. sp., Anthoecia Spraguei Grote, Heliothis um- 

 brosus Grote; (I am still uncertain that the latter is identical with the 

 European IT. armigera Hub., the Chicago specimen being quite stout 

 and large and more distinctly marked than my single European speci- 

 men, and I shall be glad to discover and compare the history of our 

 American species with its foreign representative). Catocala palseogama 

 Guen. and C. amatrlx Hiib. (= C '. selecta Walk.), the latter repre- 

 sented by an apparent variety which I have observed in both % and 9 , 

 in which on the basal space, and again over the reniform spot across the 

 terminal spaces to external margin, the anterior wings are strongly suf- 

 fused with dark brownish shades. This form has the appearance of a 

 distinct species. There is also a specimen of 0. desperata Guen., a 

 near ally of C. vidua A. & S. sp., but a quite distinct, less robust, purely 

 mixed greyish species, and which is more common in the Eastern and 

 .Middle States than C. vidua, of which latter I have a specimen accord- 

 ing with M. Gueuee's identification from New Orleans. I have seen 

 in Collections specimens of C. desperata frequently labelled C. vidua, — 

 the material in the Collection of the Entomological Society assures me 

 however that these species are perfectly distinct. Specimens of 

 Arctia virgo Linn, sp., Arctia arge Drury, sp., Spilosoma virgin ira 

 Fabr. sp., Spilosoma nov. sp.. Halisidota cart/se Harris, sp., Nadata 

 gibbosa Abb. & Sm. sp.. Tolype velleda Stoll. sp.. Limacodes scapJia 

 Harris, and Grluphtsia trilineata Pack., are among the Bombycids. 



CIRIS, Grote. 

 Ciris Wilsonii, Grote. 



I have as yet seen merely the typical specimen of this beautiful spe- 

 cies which I described in 1863, dedicated to the late learned Dr. Thos. 

 T5. Wilson. It would appear that the specimen is a male, though T cannot 

 be certain of the fact. As Eudryas Wilsonii, it would disturb the 

 homogenity of the genus since it differs from E. grata and E. unio in 

 the •' ultimate structure" of some of its parts. I regret that T have 

 not sufficient material to determine its position with more certainty than 

 at present. The strongly pectinated antenna?, which are also stouter 

 and shorter, are very distinct from the nearly simple slender antennae
