Plectes and Cechenn,s founded on the relative proportions of the 
head and thorax. The nature of the surface of the elytra furnishes 
the other secondary characters of these divisions, and such Avas the 
method of Messrs. Clairville and Bonelli. 
The greater number of these species inhabit Europe, Caucasus, 
Siberia, Asia Minor, Syria, and the north of Africa to the thirtieth 
degree of north latitude. Some fcAV are also found at the tAVO extre- 
mities of America, and it is probable that others may be found in 
the intermediate mountains (a). 
Of those Avith a convex and oblong body, the most common 
is the C. auratus,\-t.-, Panz. Faun, Insect. Germ., LXXXI, 4, 
commonly called the J ardinier . It is about an inch long, golden 
green aboA^e, black underneath ; the first joints of the antennae 
and the legs fulvous; elytra sulcated, unidentated on the exterior 
margin near their extremity, particularly in the female, Avith 
three smooth ribs on each. 
This Insect disappears in the south of Europe, or is only 
found there in the mountains f . 
Those are most generally furnished Avith Avings. Their mandi- 
bles are transA^ersely striated, and Avithout any visible teeth on the 
internal side. The thorax is transversal, dilated equally, rounded 
laterally, and Avithout any prolongation at the posterior angles. The 
abdomen is almost square. Their exterior palpi are less dilated at 
the extremity. The maxillae are suddenly curved at the extremity.

(a) Of the species that inhabit North America, we have as yet only discovered 
the C. Beauvoisi, carinatus, Lberminier ? lineal opunc tut us (serratus, Say), and syh’osi/s 
and vinctus. The mountains of New Hampshire, and JIaine particularly, probably 
contain several others, and it is to be hoped that some friend of the science, within 
reach of those localities, Avill soon enable us to enlarge our catalogue of this interest- 
ing genus. — E ng. Ed.
