tinct species in those countries. The most prominent difference was 

 found in tlie length of the antennvl pectinations in the same sex. The 

 Xeraeophihi rufula Boi'.-id., foiuiJe 1 on a single individual in indiffer- 

 ent conservation, is now referred (ib. p 70) to the genus Arctia. We 

 suspect that this specimen will prove to belong to .\ntarctia punctata 

 Park. Under its synonym, PhocjjDptern., Dr. Boisduval describes three 

 Californian species of Halisidota. Of these P. quercus, p. 81, is 

 Halisidota Edwardsii Pack., P. scdicis, id. is Halisidota californica, 

 Wil/cr, and P. cinnan^mea, p. 83, is not improbably, H. roseata 

 Wal/c, or at least an allied species. Under the genus Bombi/x, Dr. 

 Boisduval enumerates the American species of Glisiocampa. Bomhi/x 

 //•uteforam, p. 82, is a fresh synonym of C. americaua Harris. We 

 had not previously heard that it occured in California. Bomhi/x 

 drupacearum is again a fresh synonym of C. disstria ; and again the 

 habitat of California, where the species is said suspiciously to be 

 '•beaucoup plus rare," is new and doubtful. Finally B tmbijx ps^oiul- 

 one^tstria, p. 82, is C. californica Pack. As Lasiocampa carprinifulia 

 p. 83, Dr. Boisduval describes a species of Grastropacha from California ; 

 but we doubt that to this new species the Phalaena iUcifolia of Smith 

 should be cited. Dr. Packard has shown that Smith may have in- 

 tended under his erroneous determination either Gr. americaua Harris., 

 or G. ferruginea, Pack., from our Atlantic District. The figures of 

 Abbot& Smith, whatever may be said of their fidelity, are not to be re- 

 lied on to distinguish such closely allied species. " Saturnia ceannthi, 

 Behr," is Platysamia californica, and it appears also to be the species 

 "mentionne" by the name o( •^Eari/aius" by Dr. Boisduval in 1855. 

 We have as yet seen no description of this species prior to H65. 

 Pseudohazis eglanterina is cited under Hiibner's genus Telea, of 

 which our T. polyphenius is typical. Two species of Hepialus, FI . 

 hectoides, p. 85, and H. californicus ib., afford the first evidence of the 

 existence of this genus in California we have yet met with. As 

 Dicramira scolopendriaa, Dr. Bjisduval describes wh it is apparently 

 an interesting Western representative of the genus Cerura. A new 

 species of Ichthyura is described as Clostera incarcerata p. 80 ; but 

 from the text it is not certain that it is from (lilif »rnia. (Iluphisia 

 trilineata Park., is considered as the same as the European G. crenata 

 on p. 87, and additionally registered from California. As Alastor 

 gibhosa our Nadata gibbosa is registered from California. Dr. Pack- 

 ard has shown the existence of two closely allied species of the genus 

 from our Atlantic District. Should a species occur in California it
