Tue natural history of the cognate genus Ascelaphus was given 
at length in a former communication to the Linnean Society : 
the details of Formicaleo will be found equally complete, with 
the exception of the ova, which have not yet been noticed. It 
is remarkable that, after a long-continued search, not a single 
perfect insect has been found by me in a state of liberty, though 
the larvze swarm under every rock or shed calculated to pro- 
tect their pitfalls from the rain and wind; so successfully are 
they secreted from every enemy by their peculiar mode of rest- 
ing, and the favourable colour of their bodies. No true Myr- 
meleon has yet occurred in St. Vincent. Mr. Donovan in his 
Naturalist's Repository, under the article M yrmeleon libelluloides, 
plate 139, has committed a great error in mistaking the larva of 
these insects, which has been so long known, for an apterous 
female. 
The valuable characters of this family which the great French 
entomologist has given in his Genera Crust. et Ins. require some 
little correction. -He should-rather have said, Antenne &c. 
apice post mortem compresse ;—these organs, as in the Asca- 
laphi, shrinking much when dry. Palpi maazillares externi arti- 
culis quinque.&c. . . . ultimo ad apicem acutiusculo vel obscure 
emarginato.
