and proportionately broad. In Luxerii there are two small 

 oblique whitish spots, near to and parallel with the angular sides 

 of the scutellum, which are wanting in this species ; a longish 

 tear-shaped white spot alongside of the suture, distant from the 

 base about |^rd of the length of the elytra, is also wanting here. 

 In Luxerii there is an oblique triangular spot near the apex, in 

 some examples connected with the margin by a slender baud, 

 showing that this is merely a part of an interrupted hooked 

 band. In Lowei this spot is confined to a small round or thread- 

 like dot. The white margin is a good deal broader than in 

 Luxerii, and a blackish violet-coloured edging on the outer side 

 of the white margin is a good deal more prominent than in that 

 species. The greater extent of the interior obscure space, arising 

 from the larger size of the insect and the want of the small 

 white] spots in the middle and towards the base of the elytra, 

 readily distinguish this species from Luxerii. 



I have received four specimens, all of which are constant in 

 the above characters. 



I have named this species after my valued friend. Dr. William 

 Henry Lowe of Balgreen, a naturalist of great ability and acquire- 

 ments.

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 foveae 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-
