Observations on the various Insects 
had been bred from them. The horns of the larvae appear fur- 
cated at the second joint, from the bristle being incrassated, and, I 
believe, jointed : the jaws are strong, curved, and acute (y) ; there 
are five minute eyes on each side of the head, which is reddish- 
brown, with a semicircular line of the same colour on the first 
thoracic segment. The body is white, shaded with ochre, the in- 
testines shining through the back behind : at the tail is a thickish 
foot, and above it two jointed tapering tails, all ochreous : the 
six pectoral legs are of the same colour : length, 2 lines (k). The 
beetles of which these are the larva? are Coleopterous, of the 
Family Staphylinidte, and this group forms the Genus 
OxYTELUS of Gravenhorst ; the species is named by the same 
author 
8. O. sculpturatus, the Sculptured rove-beetle, from the deep 
channels upon the thorax : it is depressed, pitchy black, and 
shining, excessively, thickly, and minutely punctured, and stri- 
ated, with large points scattered over the surface : horns remote, 
short, hairy, thickened considerably at the extremity, eleven- 
jointed, basal joint long, forming an angle with the second, which 
is small and pear-shaped ; third and fourth minute globose, 
the remainder broader than long, being somewhat cup-shaped, 
excepting the terminal joint, which is the largest and ovate-conic; 
mouth brown ; jaws strong, arcuated, pointed, with a tooth on the 
inside : feelers visible, maxillary four-jointed, labial three-jointed, 
the terminal joint slender and often ferruginous : head frequently 
as broad as the thorax, transverse-ovate, flattened between the 
eyes, with an elevated ridge near each, and two short channels on 
the nose, with an obscure one at the base : thorax transverse, the 
lateral margins smooth, three broad channels down the back, the 
central one deepest ; scutel invisible ; elytra nearly quadrate, often 
pitchy or brown, and rarely testaceous ; wings very ample, trans- 
parent, and folded under the wing-cases in repose : body very 
glossy, rather short, linear, the sides margined, apex pointed ; six 
legs, short and ochreous ; the thighs stoutish ; shanks spiny out- 
side : the first pair notched externally at the apex ; feet rather 
long, slender, and triarticulate ; basal joints minute, third long 
and clavate ; claws long, slender, and acute: length from 1^ to 
If line ; expanse of wings, from i of an inch to 4 lines (fig. 29). 
It is impossible to turn over any dung which has been dropped 
only a few hours without finding it taken possession of by insects, 
and amongst them the O. sculpturatus and O. rugosiis* will 
generally be recognised : when such deposits are a few days old 
they often swarm with these and other Coleoptera. They are able 
* Numbers of this species were discovered in the clubbed roots of bro- 
coli, in the middle of September, in a garden in Surrey.
