rope must be regarded as the home of the genus, the number of species in our 
own country far exceeding that of the whole of the other districts put together. 
According to Staudinger’s last catalogue, thirty-four species are found in 
Europe and the adjacent territories, including Siberia, four or five are known 
to exist in Japan, and probably the same number in northern China, while the 
list of North American forms, including those mentioned in the present paper, 
has increased to no less than eighty-three species. In the islands of the 
southern Pacific and Australia are several genera which recall the color- 
ation and structure of Catocala, but are separated from it by well defined 
limits, and it is almost certain that no true example of the genus is to be 
found in the southern hemisphere. Our northern States species have been 
recently admirably figured by Mr. H. Strecker, in his Lepidopt. Rhopaloc. et 
Heterocera, while Mr. A. R. Grote, of Buffalo, has published, in the Trans. 
Am. Ent. Soc., Vol. 4, 1872, descriptions of the whole of those then known to 
him. In Mr. Grote’s valuable paper he has tabulated the genus as follows: 
Section 1. Secondaries black and unbanded above.

It is somewhat remarkable that, with one exception, the whole of the Pa- 
cific Coast species at present’“known belong to the third section, viz., those 
which have the lower wings of various shades of red, sections one, six and 
seven being entirely unrepresented. The late Baron Terloo is said by Dr. 
Behr to have observed at San Jose, in this State, a specimen near to Catocala 
relicta (section 2) of New England, and I myself, last year, observed in San 
Mateo County a very large species, with pale yellow median band, evidently 
nearly allied to Catocala cerogama (section 6). It was sitting on the trunk of 
a large tree of Hsculus californicus, but to my great regret, evaded my attempt 
to capture it. I could not, however, be mistaken in the color of the under 
wings. Itis quite probable that among our oak groves many species un- 
known to science exist, and we may confidently hope that those of our coast 
now enumerated will be at least doubled in the course of afew years. It may 
be well to notice that these insects come readily to sugar, Mr. G. Mathew, of 
H. M.S. Repulse, being so fortunate as to capture no less than 27 specimens 
of C. Aholibah, Streck., in a single night, on some oak trees prepared by him 
at Esquimalt, Vancouver Island. 
The following are the species at present known to inhabit the Pacific Coast:
