 purpurea vel violaceo micantibus. Lo7ig. 5' 5-6' 5 millim. S 5- 



Mas, capitis basi profunde excavato-eroso, erosione ima lota 

 7tigra : fronte elevata, in medio profunde sidcata. Antennis 

 aciite serratis, articido quinto triangulari apice nigro. 



Femina, antennis brevioribus, leviter serratis.

The head in the male is deeply excavated ; the surrounding parts 

 are yellow and elevated, bvit very differently from either of the 

 lledybii described by me in the 'Annals and Mag.' for Jan. 

 1900*. The deep notch in the front part of this elevated edge 

 of the crater is of itself sufficient to prevent its being confused 

 with them. The base of the crater in the male and the base of 

 the head in the female are black. The antennfe ai-e more acutely 

 serrate than in any other species I have seen. They vary in the 

 degree to which they are marked with black. Their second joint 

 is very short, the third as long as the basal, the fourth and fifth 

 triangular, the last in the male always black in its apical half 

 and more acutely produced inwards ; the following joints are 

 longer, acutely serrate, and more or less dark, in the females I 

 have seen always dark. 



The thorax is of the same shape as in H. amce^ius, H. ancejjs, &c., 

 but the disk is nearly all suffused with blue-black, two dark points 

 project on the base, and it is sometimes indented on each side in 

 front. 



The scutellum is black ; the elytra are blue and often have a 

 beautiful metallic-violet reflection, they are finely coriaceous. 

 The legs are yellow but tinged with black, and the hind pair are 

 altogether dark, in which respect this insect also differs from any 

 of the Hedybii of this group described. 



Three males and two females of this species were sent me by 

 Dr. H. Brauns.

 articidis basi tribus rufis usqite ad apicem infascatis. Long. 

 4-4-5 millim. d 5 .

 duplici quasi elevato, cornu anterior e apice ciliato, 2}osteriore 

 hamato apice nigro, sujyra ocidos tuberctdato.

Head, thorax, base of the antennte, margins and apex of the 

 abdomen yellow ; the scutellum and elytra are bluish green. The 

 upper side is finely clothed with a pruinose silky jjubescence, 

 long hairs are absent.
