The American alpine insect fauna is regarded as a fragment of that 
which survived the geological changes occurring at the close of the Ter- 
tiary and beginning of the Quartenary epoch. Observations are made 
upon the hypsometrical distribution, &c., of the insects observed.

The author endeavours to prove that insects did not first appear as 
larval forms, but fully developed, in the shape of a hypothetical Proten- 
tomon, derived from the worms, not from the Crustacea. In discussing 
the ancestry of the orders of insects, he commences with the Hymeno- 
ptera and ends with the Neuroptera, placing the Coleoptera near the, 
Hemiptera and Orthoptera. For an able review, see A. S. Packard, Am. 
Nat. X. pp. 688-691. No new facts, according to the latter (who is 
assuredly a competent judge on such a point), are adduced by the author.
