males and females derived from the nymphz of the second form. 
That rather these nymphae remain wingless, and never leave their 
nests in which they develop themselves under conditions into 
males which can beget offspring, and into females which can lay 
eggs. These nymphe, like mature animals, are already observed 
with several species, and have been usually described as 
queens. Joly illustrated a queen of Termes lucifugus, without 
wing-cases, and Lespes reports that Joly assured him also that the 
same had been seen without a trace of wing-cases. Besides, Bur- 
meister described a female of Termes flavipes as a wingless queen, 
and Dr. Hagen, who examined the same animal, found it had 
about the same habit as a queen with the short wing-sheaths of 
anympha. He also considers Bates’ queen of Termes arenarius as 
a nympha with undeveloped wing-sheaths. (Communicated by 
letter of January 2nd, 1872.) 
Further, I take here in consideration a specimen of Calotermes 
flavicollis which is in the British Museum, described by Walker 
among Termes lucifugus, a nympha with short wing-cases, 
deceptively like an imago which has lost the wings. The 
uniform black color, the shining polished head, thorax and body, 
exclude the idea of another moulting. (Dr. Hagen 12, pages 20 
and 59, and at other places.) Therefore the males and females 
of certain species of Termites appear under two different forms. 
The ones arising out of the nymphae of the first form receive 
wings, and leave their birthplace inswarms. Only very few lucky 
ones among them are so successful as to ascend later a vacated 
throne as king and queen. The others, which have become the 
matured nymphz of the second form, never see the light of day; 
they remain wingless, and never leave the nest in which they have 
grown. Of what importance is now the preservation and the suc- 
cess of the species of each one of these two forms? A large 
*Dr. Hagen writes me that all queens (of Termes bellicosus, — obesui, gilvus) 
which he saw, from Asia and Africa, are really imagines with the wing-stumps from 
the wings are broken. On the contrary, all queens (of Termes flavipes, morio(?) 
similis(?) arenarius) which he had seen from Brazil and America were decidedly xou

I have seen here more than a banked ix real queens, more than Dr. Hagen, from Asia 
and Africa, before I found for the first time nympha-like females,
