The tenth joint of antennae of the male is rather large, 

 and grooved on one side for the partial reception of the 

 eleventh, from one direction it appears to be divided into 

 two, so that the antennae seem to be twelve- jointed ; the 

 eleventh is about the length of the three preceding combined, 

 fairly stout on the apical half, and strongly narrowed (on 

 one side) to the base, near the base there are two spines, a 

 rather short outer one directed outwards and forwards (from 

 some directions this appears to belong to the tenth joint), 

 and a longer one on the lower side, directed downwards 

 and backwards. The colours are as on many other species, 

 but the armature of the eleventh joint distinguishes from 

 them all.

<3 . Black ; prothorax, scutellum, labrum, parts of 

 under-surface of head, and of three basal joints of antennae, 

 knees and front coxae flavous. With very short pubescence. 



Head shallowly depressed in front. Antennae rather 

 long and not very thin, two apical joints distorted. Protliorax 

 twice as wide as long, margined throughout, wider near 

 apex than at base. Elytra parallel-sided to near apex; with 

 dense and small, rugose punctures, coarser in middle than 

 elsewhere. Subapical segment of abdomen deeply triangularly 

 notched. Length, 6*5 mm.

The tenth joint of antennae is slightly shorter than the 

 ninth, slightly wider at apex, somewhat lopsided, and with 

 a notch at the apex on the under-surface; the eleventh is 

 irregularly curved on one side, appears widest at base, and 

 from another narrower than the tenth, and on its under- 

 surface there is a long irregular groove ; it has also a small 

 basal spine invisible from most directions, and from some 

 appearing to be attached to the tenth. Except for the 

 labrum the upper-surface of the head is entirely black, and 

 this with the pale scutellum associate the species in my table 

 with H. pallipes, and H. laticollis, the former has legs 

 almost entirely pale, and the latter with a greater portion 

 dark, they have also different terminal joints; it is larger 

 than any other species, having the elytra entirely dark and 

 terminal joints distorted.
