106 MONOÖBAPflICAL ESSAT ON THE 



between the two portions is bright coppery. Elytra cyaneous-black , 

 each with a yellow spot just at the base, two spots before the 

 middle placed abreast, the exterior one below the shoulder, the 

 other one near the suture, a small band below the middle , touching 

 the outer margin only and a spot close to the apex. Beneath green 

 with blue and violaceous tinges; legs entirely testaceous, the last 

 tarsal joints blackish. 



Head very closely punctured, with a rather strong longitudinal 

 ridge in front; hairy. Antennae very long, chiefly in the male 

 sex. Prothorax convex , sides rounded and rather strongly narrowed 

 towards the top, slightly margined along the front and the sides; 

 deeply and regularly punctured, with a feebly impressed dorsal 

 line; hairy. Elytra gradually narrowed towards the top, apices 

 moderately divergent, suturai and marginal spines strong and acute , 

 the humeral fold middle-sized, acutely produced ; costate, interstices 

 plain, slightly transversely wrinkled, with a row of closely set 

 small punctures on each. Undersurface coarsely punctured , the 

 abdomen more thickly and finely; clothed with a minute silvery 

 pubescence. 



This species is very closely allied to the next following A. 

 Samouelli Saund. , and in my former paper on the genus, when 

 having but a single specimen at my disposal, I only considered it 

 a variety of Samouelli with entirely testaceous legs. Disposing now 

 of a larger material, I find the following principal differences, 

 viz. the general shape is more slender; the distribution of the 

 colors on the thorax in the male is quite different; the humeral 

 spot is not composed of two confluent spots ; there is no punctiform 

 yellow spot at the base in the shoulder edge. 



Variability. The humeral and the second suturai spots have 

 a tendency to become confluent , but even in the specimen , where 

 they are almost united , there is no trace of the third spot , which 

 is always present in Samouelli. The thighs, chiefly of the hinder 

 legs, are sometimes partly bluish. 



Number of specimens examined: four, in coll. Oberthür and
