NEUROPTERA. 
Catharina, Brazil) that many of the popular and scientific ideas on 
important points are pure misconceptions, and, in the main, upholding 
the assertions of Lespes, many of which had been called in question. 
Taking as a type a colony of a species of Terines, he arrives at the 
following conclusions : — from very young larvte, the future states of 
which are not determinable, there are produced two main larval condi- 
tions ; first, larval forms not fitted for reproduction, developing respectively 
into soldiers and workers ; secondly, larvae of forms fitted for repro- 
duction in different degrees. These larvae develop into nymphs of two 
forms ; from the first are produced winged individuals, the greater part 
of which appear to die without performing the sexual function, but some 
of which become ' Kings ' and ' Queens ' ; from the second form there pro- 
ceed nymphs that in turn become ' surrogate ' or ' complementary ' males 
and females that never leave the termitarium, but are nevertheless capable 
of reproduction, the abdomen of the female never swelling to the enor- 
mous size of that of the queen, and the ovaries containing but few eggs. 
One small nest opened by the author contained a large chamber, but in 
it, instead of a queen, he found 31 complementary females and a single 
true fully developed king, the females depositing eggs, and thus, as he 
expresses it, instead of a royal palace with queen of royal birth, he had 
before him simply a harem, in which was the king with a multitude of 
paramours. The popular idea of pairing taking place in the air he also 
doubts. According to observations on several species of Calotermes, he 
found that the worker-form did not exist with them, and he proves that 
the soldiers are apparently arrested developmental forms, for even the 
external sexual characteristics were present, and dissection proved that 
the testes of the males existed, although in an aborted condition, and 
that the female internal organs were developed, with the exception of 
the seminal receptacles. Several new species are indicated, but diag- 
nostic characters of the perfect insects are only given in two instances, 
viz. : — Calotermes canellce (p. 334) and Termes lespesii (p. 349). A new 
genus — Anoplotermes (p. 347) — differs from all others in a point of 
internal structure, and includes a species indicated as A. pacificus, and 
probably also Termen ater^ Hagen, and T. cingulatus, Burm. The papers 
are illustrated by many woodcuts showing the structure of the nests ; 
the plates are devoted to matters of internal anatomy.
