506 GEOGRAPHICAL DISTRIBUTION OF INSECTS. 
polis. I say as to latitude, because these groups have often 
an extensive one as to longitude. Thus, Mr. W. S. Mac- 
Leay has remarked to me, that Goliathus appears to 
belt the globe, but not under one form. The types of the 
genus are the vast African Goliaths (G. giganteus, &c.), 
which, as well as G. Polyphemus, and another brought 
from Java by Dr. Horsfield, have, like Cetonia 3 -, the sca- 
pulars interposed between the posterior angles of the 
prothorax and the shoulders of the elytra b : while the 
South American species (G. mi cans, &c.) have not this 
projection of the scapulars ; in this resembling Trichius. 
Mr. MacLeay further observes, that the female of the 
Javanese Goliathus is exactly a Cetonia, while that of the 
Brazilian is a Trichius. But quiescent groups have not 
generally this ample longitudinal range. Thus, Eu- 
glossa, in both its types, — one represented by Eu. cor- 
data, and the other by Eu. surinamensis, — is confined to 
the tropical regions of America. Doryphora, likewise 
American, seems equally confined. Asida, though a 
southern genus, is not found to enter the tropics; and 
Manticora and Pneumora are in nearly the same predica- 
ment. 
Under the present head we may consider what may 
perhaps be denominated without much impropriety en- 
demial groups ; by which I mean those groups that are 
regulated, as to their limits, not so much by the tempera- 
ture, or the northing and southing of the latitude, as by 
the general aspect and circumstances of the country. 
Thus, the vast and nearly insular continent of Africa,
