face ; another transverse depression separates the clypeus from 

 the labrum. In the present species these depressions and ele- 

 vations are, with the following exceptions, not visible. The 

 head looks as if a heavy roller had passed over it, smoothing or 

 crushing down all inequalities. The whole head is a flat opake 

 surface, with the exception of the transverse division separating 

 the labrum from the clypeus, and the clypeus from the rest of 

 the head, and of a couple of oblique lines (they can scarcely be 

 called grooves) tending inwards from the side of the eye. An- 

 other difference is observable in the sulcation of the elytra ; but 

 as this may be variable, I do not insist so much upon it. In 

 my specimens of T. Megerlei the sulcation is as follows : — the 

 first sulcus next the suture comes down to the apex alone ; the 

 second is joined before it reaches the apex by the fourth, and 

 encloses the third ; the fourth again joins the sixth, enclosing 

 the fifth ; and the seventh comes down alone. 



In the present species, on the other hand, the first, as in Me- 

 gerlei, comes down alone ; but the second, instead of joining the 

 fourth and enclosing the third, joins the sixth ; then within these 

 the third and fifth join, and enclose the foui'th. Trifling varia- 

 tions in the decidedness with which these junctions take place 

 may be seen even on different elytra of the same insect ; but I 

 think the above is the normal character of these two species. 



I have received two specimens of planifrons. On receiving 

 the first, I was disposed to look upon it as a variety or distortion 

 o^ Megerlei; but as I found the same characters occurring in 

 the second, I am satisfied that it is a good species. These cha- 

 racters, more particularly the levelling of the head, which is very 

 marked in both of my specimens, enable us at once to distin- 

 guish them from Megerlei.

The colour above is a decided green, without the blue tinge of 

 emarginata, Fab. The labrum, mandibles, palpi and antennce are 

 rufous, the tips of the mandibles and the end of the first joint 

 of the antennae becoming fuscescent or blackish. There is no 

 blackish ring on the second and third joints, as in emarginata. 

 The under side is of the same colour as the upper, with the ex- 

 ception of the breast [mesothorax and metathorax), which is ru- 

 fous. The head is oblong-square, extending two-thirds of its 

 length before the eyes, which are not very prominent ; it is
