288 MODERN CLASSIFICATION OF INSECTS. 
garded as the most anomalous annulose animals with which we are 
acquainted ; and which, either as respects their anatomical characters, 
or the many obscure points connected with their economy, may justly 
be considered to merit the epithet bestowed upon one of them by 
Latreille : ‘‘ Systemata entomologica perturbare videtur cum ex ordi- 
nibus omnibus repellatur —animalculum—animum excrucians. Tempus 
ducamus, et dies alteri lucem afferrent.” (Gen. Crust. &e. tom. iv. 
p. 388.) 
The insects of which this order is composed are of small size, the 
largest not reaching a quarter of an inch in Jength. (Frontispiece,

1 No account is given in the text of this work as to the locality of the species 
here figured and dissected. I am enabled, however, to state, that it was obtained by 
Mr. G. B. Sowerby from the abdomen of a bee, forming part of a collection 
received by him from Nova Scotia.
