tionate in these species to a degree comparable with that of the 
jaws of a Carnivore among Mammals. The higher kinds also 
supply the young with food, either by storing it or by direct feed-

The above characteristics show that the tribe of Hymenopters 
takes the lead among Insects, and therefore stands at the head in 
the subkingdom of Articulates. 
Note on Size under the Insect-type.—If, then, Hymenopters stand 
first among Insects, we may learn from the higher of the species 
the normal size of the Insect-type under its best condition as to 
stru 
archetype, and may be less to any degree; (2) the more inferior 
the group in which large forms occur, the greater the amount of 
Sormis, anthraciformis, musceeformis, &c. In the Diptera we find Bombylius, 
resembling, as its name implies, Bombus; and also iphria, which so closely apes 
the humble-bee in its form, coloration, size and flight, even to the buzz, which is, if

one sub-order to obtain a bizarre form which i

Addition to Note, while in the press.—These, and other observations beyond, for 
which I am indebted to Mr. Packard, are so apposite to my subject as to cpp as 
if prepared for the use here made of them. In fact, however, my with its 
notes was written without any acquaintance with the author beyond what I had 
derived from his valuable pl sbi also without his knowledge. 
Some Hymenopters can with their wings or legs; but none are semiaquatic.
