new Species of the Coleopterous Family Paussidce. 95 
humeris antice et fere ad marginem posticum loborum thoracis 
productis. Pedes tenues, subcompressi. 
I have dedicated this very interesting insect to M. Hippolyte 
Gory, a distinguished French Entomologist, member of the En- 
tomological Societies of London and Paris, and author of various 
valuable works, who has been so obliging as to forward it to 
me from Paris, although unique in his rich collection, in order 
that I might describe and figure it for the Entomological Society 
of London.

Cerapterus Macleayii, Donovan. 
Plate X. fig. 7. 
This insect is known to Entomologists only by Donovan’s figure 
and description ; and as this author is known not to have paid so 
much attention to the minute details of his figures as are now re- 
quired by Entomologists, I have thought that a figure of an insect 
sent to me from Paris by M. Gory, which, except in a few par- 
ticulars, agrees with the general characters of this species, would 
not he unacceptable to the Members of our Society. It is from 
New Llolland. 
Piceus, antennis pedibusque rufo-piceis ; capite thorace minori, 
obtriangulari, antice rotundato, angulis posticis pone oculos 
acute productis ; postice in collum breve contracto : thorace 
subcordato-truncato, capite majori ; elytris thorace latioribus, 
oblongo-quadratis, angulis posticis tuberculo ordinario in- 
structis ; pedihus magnis, compressis ; tarsisdistincte 5-articu- 
latis. 
Long. lin. 5. 
The characters given above might, perhaps, be considered to 
indicate a species distinct from C. Macleayii ; but I think when 
sufficient allowance is made for Donovan’s inaccuracies in minute 
insects, and his figures and description are compared with those 
which I now offer, it would not he justifiable to give the insect 
above described as a species distinct from that figured by him.

Genus. Trochoideus, JVestm. 
In my Monograph upon the Paussidce I introduced the Paussus 
cruciatus of Dalman into the family, under the generic name of 
Trochoideus, observing that the general habit of the insect, the
