the lobe formed by each side of the eniargination gently 

 rounded ; the under plate of the same segment is more 

 produced than in the female, and its posterior margin is 

 gently rounded. 



In the female, the upper plate of the seventh segment 

 of the abdomen has the apex with a distinct triangular 

 notch in the middle ; the posterior margin of the under 

 plate is not rounded, but a little acuminate in the middle. 



I have found this species only in Scotland ; Edinburgh, 

 Rannoch, Strath Cannich. 



Ohs. — This species has the structure of the antennas 

 very much like that of H. fungicola and its allies, but it 

 is certainly in its place here, in the neighbourhood of 

 fvngivora and excellens. Two specimens ( $ and ? ) of 

 H. picipes sent by Kraatz to the British Museum agree 

 entirely with my specimens.

Antennae rather short, black, distinctly but not greatly 

 thickened towards the apex, second and third joints rather 

 short, the third not quite so long as the second, four to 

 ten each distinctly broader than its predecessor, seven to 

 ten distinctly transverse; eleventh joint about half as 

 long again as the tenth. Head considerably narrower 

 than the thorax, black, rather dull, its punctuation indis- 

 tinct, with an impression in the middle, more distinct in 

 the male than in the female. Thorax narrower than the 

 elytra, fully one-third broader than long, a little narrow- 

 ed behind, the disc flattened, sometimes with a large im- 

 pression, sometimes with a fovea in front of the base in 

 the middle, from which proceeds a channel; its sculpture 

 and pubescence moderately fine and not dense. The ab-
