POLYCTESIS IGORROTA, 

 NOVA SPECIES BÜPRESTIDARÜM 



K. M. HELLER. 



Statura habitusque P. rhoidis , cuprea , elytris viridi-cyaneis, 

 maculis flavis ornatis ; una macula oblonga prope scutellum^ 

 una curvata circa angulum liumeralem , una in medio prope 

 suturam , una transversa ante apicem et pars media mar- 

 ginis lateralis Jlava ; elytris punctatO'Striatis , interstitiis pri- 

 mis , secundis et tertiis antice obscure subtiliterque . interstitiis 

 reliquis distincte remote striato-punctatis ; scutello punctiforme 

 subtransverso ; thorace lateribus late flavo-marginato ; seg- 

 mentis abdominis utrinque Jlavo-guttatis. Long. 12 — 14 mm. 



Habitat in insula Luzon. 



Agreeing in size and shape with Polyctesis rhois Mars., 

 but differing in colour and sculpture , and consequently 

 easily distinguishable. 



Coppery, elytra dark blue-green, each of them with the 

 following yellow spots: an oblong spot near the scutellum, 

 a c-shaped one around the shoulder , one about the middle 

 of the length near the suture, and an undulate transverse 

 band at the base of the posterior third. 



The spots seem to be variable in form , as one of my 

 two specimens shows the hinder part of the humeral spot 

 widened out, so as to form a circular blot, and the trans- 

 verse band, which extends over eight interstices, simply 

 curved ; the other specimen has an additional small longi- 

 tudinal stripe inside of the shoulder-protuberance , and the 

 transverse undulate band recurved in front near the suture. 



The sides of the thorax are rather broadly margined 

 with yellow.
