 Under Cramer's later specific name, Br. Boisduval records Deilephila 

 lineata Fahr. spec, as a habitant of California. In our " Sphingidae" 

 (1865), will be found the full synonymy of the species, with the ex- 

 planation that Fabricus' first description (1775 and therefore earlier 

 than Cramer's Vol. 2 — 1779) applies to our Amjrican species and n tt 

 to the European Deilephila livornica. Further on Boisduval records 

 the European Deilephila galii as found in California, and considers 

 our Deilephila chamoenerii Harris^ as the same species. Sphinx se- 

 quoiae Boisd. and Sphinx strobi Boisd. (the latter possibly not cor- 

 rectly attributed to California) are then described. These appear to 

 belong to Hiibner's genus Hyloicus. In the Castniiuae six species are 

 described under the genus Agarisfa. For all of these species known 

 to us the generic term Alypia should be used. The first — Alypia 

 octomaculata — our common species from the Ath^ntic District, is un- 

 known to us from Califjrnia, and from analogy we are led to regard 

 Dr. Boisduval's habitat as an error. All the species of this genus 

 from the Western District of our Continent have the spots on both 

 pairs of wiug.s above yellow or yellowish, while A. octomaculata, A. 

 langtonii, etc., have the spots on the secondaries white. This is a 

 very interesting fact, pertinent to a study of the relationships between 

 coloration and geographical distribution in insects. Dr. Boisduval de- 

 scribes Alypia dipsaci G. & /?., Alypia lorquinii G. & R., and Alypia 

 mariposa, G. and R., previously illustrated by us under the same 

 specific names. Under the genus Ctenucha Dr. Boisduval describes 

 two species, C. robinsonii and C. harrisii, apparently belonging to the 

 second section of the genus. '' 0. rubrnscapus" is C. multifaria* 

 Walk, spec; while 0. corvina Boisd. p. 71, is a synonym of C. 

 ochroscapsus, G. tt R.. described by us from specimens in the Ber- 

 lin Museum. Dr. Boisduval credits Ecpantheria scribjnia to Califor- 

 nia and describes four species under the genus Ckcltmid, of which C 

 achaia, is Arctia achaia, previously illustrated in these pages. Arctia 

 sciurus Boisd. ib. p. 79, is not improbibly Lcucarctia californiea 

 Packard. Of L. acraea, Dr. Boisduval remarks that it is found as 

 far south as Central America. The specimens we have seen from 

 Mexico and Central America, seem to indicate the existence of a dis-
