A species not much resembling the preceding ones; 

 somewhat like a broad flat H. elongatula, but readily dis- 

 tinguished by the antennge being furnished with long pro- 

 jecting hairs, more distinctly than is usual m the genus. 

 The antennfe are moderately stout, gently thickened to- 

 wards the apex, the basal three joints rather elongate, 

 lighter in colour than the following ones; joint three 

 longer than two, four to ten each a little broader than its 

 predecessor, four to six about as long as broad, seven to 

 ten transverse ; eleventh joint about half as long again as 

 the tenth. Head rather broad and short, narrower than the 

 thorax, somewhat narrowed behind, rather shining, finely 

 and sparingly punctured, sometimes with an impression 

 or channel on the disc. Thorax a little narrower than 

 the elytra, rather flat, more than one-third broader than 

 long, a little narrowed behind, finely and not densely 

 punctured. The elytra are rather longer than the thorax, 

 brownish, not densely but distinctly punctured, and fine- 

 ly alutaceous. The abdomen is black and shining, red- 

 dish-yellow at the extremity, segments two to four finely 

 and not densely punctured, fifth segment more sparingly 

 punctured, sixth almost impunctate ; the sides and apex 

 distinctly furnished with long exserted hairs. Legs clear 

 yellow. 



In the male, the dorsal plate of the seventh abdominal 

 segment has the apex truncate, but with the posterior 

 margin not quite straight; this margin is distinctly 

 thickened, and indistinctly crenulate. The under plate 

 of the seventh segment has the hind margin gently 

 rounded. 



In the female, the seventh segment above has the 

 posterior margin broadly but shallowly emarginate, and 

 terminates on each side in a small sharp projection ; on 

 the under side the same segment has the posterior mar- 

 gin emarginate, and furnished densely with short parallel 

 cilia. 



Rare. Rannoch ; and Hampstead, near London. 



Obs. — This species is, I think, best placed here; though, 

 in some respects, it is allied to H. xantJioptera.
