COLEOPTERA, 
CERAPTERUS MACLEAII. 
GENERIC CHARACTER. 
Antennae compreffed, pinnated, with the firfl; joint concave, and placed tranfverfely, and that at the 
extremity large, and rounded at the apex ; head very fmall, with the eyes prominent : thorax flat, 
fomewhat heart-fliaped, truncated, and narrower than the elytra: wing-cafes length of the abdomen, 
and embracing it at the fides : body oblong. 
SPECIFIC CHARACTER. 
Entirely brown, with the legs Ample. 
Cerapterus Macleaii : totus brunneus, pedibus fimplicibus. 
A nondefcript fpecies of this Angular genus has been received by our kind friend Mr. Francillon 
from New Holland. This is a diminutive, but moft curious creature, and is efpecially remarkable for 
the ftrufture of the antennae, which latter appear to conflderable advantage under the lens of the opake 
microfcope. The fmalleft figure in the plate denotes the natural fize, and the two larger ones are de- 
figned to ftiew its magnified appearance. 
In its general habit this infedt approaches the Paufus genusj with which the juvenile Entomologift, 
attentive only to the magnitude and club-like form of the antennae, might eafily confound it. The 
difference between thofe infedts is, indeed, obvious on more clofe infpedlion; the Paufus having only two 
joints in the antennae, of which that at the extremity is by far the largefl: j while the antennae of the true 
Cerapterus are furniflied with feveral joints, all which are of a compreflTed form, pinnated, and termi- 
nated at both extremities with one larger than the reft. 
The genus Cerapterus is defcribed by Swederus, in the Tranfadtions of the Swedilh Academy for 
the year 1788,* but does not appear to have been noticed by any other author. The defcription given 
by Swederus is taken from an infedt which he names Cerapterus Latipes, in the colledtion of General 
* Kongl Vetenskaps Academiens nya Handlingar. T. IX. for ar 17S8. p. 203 .
