This species is evidently very much like A. azureus, Erichs., 

 but appears to have darker antennse, and the tarsi are dark, 

 excepting the first joint and the basal part of the second 

 joint of the anterior tarsi in the male. In the female the 

 same joint is wholly dark,

Mas, capite antice excavato-eroso, erosioue ima et basi nigra ; 

 pone oculos elevato, quasi cornuto ; antennis longioribus, articulis 

 tertio et quarto compressis, intus modice oxpansis, subtus nigro- 

 maculatis, superne linea tenuissima aurea, quinto ad apicalem 

 superne nigro-maculatis ; prothoracc transverso, plaga magna et 

 punctis duobus basalibus nigris. 



Hub. Natal, Estcourt {Marshall). 



The specimens from which this insect was described were 

 two females. I have now the advantage of having several 

 examples of both sexes before me, and I think there are three 

 closely allied species all from Estcourt. The very extra- 

 ordinary structure of the head is not precisely alike in these, 

 and I associate the male described above with //. amoenus 

 from the spotted antennaj, and from the form and amount of 

 the black markings upon the head and the thorax, and from 

 the hind tarsi being blackish in both sexes. 



The front of the head is yellow, slightly more prominent in 

 the male than in the female, the excavated erosion is pubescent 

 at the back, and a spur of golden hairs, with a ridge of hairs 

 connecting it with the sides, is to be seen at the bottom; on each 

 side but in front of the eye a few yellow setse are found ; the 

 elevated portion which forms the back of the eye and supports 

 it is yellow and is not separated from the black temples by 

 a deep sulcus as it is in H. Marshalli ; moreover, the black 

 mark, and indeed the whole disk, is shining and not opaque. 

 These considerations lead me to believe we have here three 

 closely allied but distinct species, and that we cannot assign 

 either of them to A. erosus, Erichs., to which, however, they 

 are obviously also allied. 



Another male differs somewhat, in the coloration of the 

 antennee : the third to the sixth joints Iiave each a black line 

 above, the seventh has only an interrupted line, the apical 

 joints being yellow, and the thorax lacks the two basal dots ; 

 too much reliance therefore must not be placed on the black 

 markings.
