MONOGRAPH OF THE COLEOPTEROUS FAMILY PAUSSIDiE. 
PART I. 
[Having acquired, since the publication of my various memoirs 
on the family Paussidse, which have appeared in the Transactions 
of the Linnman Society, vols. 16, 18, and 19 ; the 2nd volume of 
the Transactions of the Entomological Society, and the Entomo¬ 
logical Magazine, vol. 5, much additional matter relating to these 
singular insects, as well as a considei'able number of new species, 
of which no figures have yet been published, I have thought that 
a complete series of coloured figures of the entire family most 
of them redrawn with care for the purpose of this work, would be 
received with interest by entomologists.] 
The family Paussidse comprises a small assemblage of exotic 
coleopterous insects, varying from a quarter to rather more than 
half an inch in length, the species of which are of extreme rarity 
in collections (single individuals only of the greater portion being 
known); and at the same time so remarkable in their structure, 
that Latreille observed, “ vainement chercherions nous dans tout 
fordre des Coleopteres un genre qui nous olfre des caracteres aussi 
bizarres, et aussi insolites que les Paussus.”—Nouv. Diet, d H. N. 
V. 25, p. 57. 
* The figures accompanying my monograph in tlic Linnacan Transactions, published fnelve 
years ago, were uncoloured.
