454 THE DISTRIBUTION OF CALIFORNIAN MOTHS. ' 
such as Hypsipetes, Cidara, Coremia; Eupithecia, Scotosia, Acid- 
alia and Boarmia 
(4) There are cite species common to both the Pacific and At- 
lantic states, viz., Larentia cumatilis, Camptogramma gemmata, 
Tephrosia Cnsadavis and Azelina Hibneraria. 
In the brief introductory remarks to the first part of this Cata- 
logue (these Proceedings vol. xiii, 381) we briefly alluded to the 
fact that some Californian Lepidoptera repeat certain features pe- 
culiar to the fauna of Europe. I find that there are but two forms 
strikingly European among the Phalenide, viz., Numeria Califor- 
niaria Pack. (wrongly described by me as Ellopia Californiaria 
xiii, p. 384) which is very near the European Numeria pulveraria, 
and quite different from the Atlantic states N. obfirmaria, and 
the genus Chesias which does not, so far as yet known, occur in 
the Atlantic region.* 
But if we find a very few species which recall the European fauna, 
there are on the other hand many peculiar European genera which 
do not occur in the Pacific region. In other groups of Lepidopters 
there are some species that recall European types ; such, especially, 
are Papilio Zolicaon Boisd., representing the European P. Machaon, 
and the genus Parnassius, which does not occur in the Atlantic 
region. 
Going out of the Phalenide, we find a few European types of 
Bombycide which occur in California and are not found in the 
Atlantic states, such as the genera Epicallia and Callarctia. 
On the other hand we find in California no such development of 
the genus Lithosia as in Europe, no species of Zygæna, no Psychi- 
de (except Phryganidia, an aberrant form); no such develop- 
ment of Hepialus, while Xyleutes robinic, as in the Atlantic states, 
represents the European Cossus ligniperda; moreover the various 
forms of Lasiocampa and other allied genera are far less numerous 
if not (L. Carpinifolia Boisd. is, according to Grote, a species of 
Gastropacha) quite wanting in the Pacific region. 
We miss again in the Pacific states any species of Telea or- 
Tropea, forms linking the Atlantic or northeastern American ento- 
mological fauna with that of northeastern Asia (Telea being — 
Topreepnted by the closely allied Anthærea and Tropæa Luna
