A good many specimens of this species have been received ; 

 but as it comes in some consignments and does not occur at all in 

 others, it is obviously an insect found at particular seasons only. 

 What these seasons are we have yet to discover.

Very similar to T. Megerlei, Dej., but a narrower insect; the 

 thorax more particularly is narrower and proportionately more 

 elongate. It is at once distinguished from Megerlei by the 

 sculpture on its head. T. Megerlei has two deep fovese on 

 each side of the head between the eyes, and the space between 

 is raised into a height or bump ; a deep transverse depression, 

 widest and deepest in the centre, separates the head from the 

 clypeus, which has a couple of longitudinal grooves on its sur- 

 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
