" Prsecedenti [D-^p/i. SM/^asn'aYoe, Hope,] affinis. Capite 

 inter oculos sulcato, tliorace aurato subtomentoso, 

 elytris roseocupreis et flavo-irroratis. Corpore sub- 

 tus Eeneo albisque capillis obsito." (Hope) . 



Head and thorax coppery golden. Elytra of a redder 

 hue, with two narrow golden pubescent bands ; one, 

 which is sinuated in its middle, situate about two-thirds 

 of the length of the elytra from their base, touching the 

 lateral margin but not the suture ; the other very short, 

 close to the apex ; there are also a few small pubescent 

 spots on the basal half of the elytra. Underside with a 

 fine close gray pubescence, which is longer on the sides 

 of the abdomen than elsewhere. 



Head very deeply channelled between the eyes, pubes- 

 cent, and punctured. Thorax twice as broad as long; 

 anterior margin slightly produced in the centre and at 

 the angles, two-thirds the length of the base; sides 

 rounded ; base with a rounded median lobe ; disk pubes- 

 cent, punctured, the puctures arranged in semicircles and 

 becoming deeper on the sides. Elytra nearly tmce as 

 long as wide, punctate, the punctures arranged in longi- 

 tudinal lines and assuming the form of short slits ; sides 

 sinuate above the middle; apex rounded. Underside and 

 legs punctured and pubescent. 



Length 4| lines ; breadth 2 lines.

E. purpurascens dificrs in having the humeral impres- 

 sions less strongly marked and the posterior angles of the 

 thorax rather more rounded, as well as in the colour, which 

 is purplish-red throughout; these differences however do 

 not appear to me to be of specific value.
