 Glossy dark glowing red, or like burnished copper, old speci- 

 mens almost black, with pale green scale markings. Rostrum 

 in basal half with an oblong shallow depression reaching to 

 front and beset with an elongate scale spot. Sides of head and 

 rostrum with another scale patch. Prothorax slightly longer 

 than broad, very finely punctate. Dorsally in the middle two 

 longitudinal scale stripes, convergent toward and confluent near 

 anterior margin, forming a narrow or broad arrow-shaped 

 figure. The lateral margins circumscribed by a scale band form- 

 ing a large oval figure. Elytra short ovate, striate-punctate. 

 Each elytron in basal third with a transverse oval figure cir- 

 cumscribed by a narrow scale band reaching from first puncture 

 row to lateral margin. In the middle two narrow parallel trans- 

 verse bands which are confluent at margin with a marginal 

 stripe, the latter of which circumscribes in apical third a trian- 

 gular figure. Prosternum, mesosternum, and metasternum 

 beset with scales, first and second abdominal sternites with a 

 large scale patch laterally. Femora with a scale spot near apex. 

 Male, length, 10.5 millimeters (without rostrum) ; width, 5.2.

In this species the dorsal arrow-shaped marking on prothorax 

 is variable, in some specimens (from Siargao) rather broad, in 

 others (from Cotabato) very slender, forming almost a straight 

 confluent, anteriorly pointed stripe.
