the antennae, palpi, anterior legs (the knees excepted), and the 

 femora and tarsi of the other legs, testaceous or rufo-testaceous ; 

 the entire upper surface densely, minutely punctate. Head large, 

 transverse, broadly truncate behind, the occipital groove very 

 deep; eyes rounded, moderately large, distant; antennae rather 

 short, not very slender, joints 9-11 thickened and elongated, 11 

 nearly as long as 9 and 10 united, 10 a little longer than 9. Pro- 

 thorax long, almost as wide as the head, oval, much narrowed pos- 

 teriorly, the lower basal portion but little dilated laterally, the 

 basal groove fine and placed close to the margin, the surface finely 

 scabrous. Elytra rather broad, long, subparallel in their basal half, 

 confusedly punctulate, substriate on the basal half of the disc, with- 

 out definite series of punctures, the interstices flat. Legs moderately 

 long, the femora strongly clavate; basal joint of anterior tarsi 

 nearly as stout as the tibia.

Hob. Amazons, Ega (H. W. Bates). 



One specimen, injured by pinning. Smaller, less robust, 

 and more finely pubescent than M. fissiceps; the head 

 truncate behind, and with a shorter and deeper occipital 

 sulcus ; the eyes smaller ; the prothorax less convex, and 

 less dilated anteriorly ; the elytra not so shining and much 

 more densely punctate ; the antennae with a longer apical 

 joint. The reddish-brown body, larger head, deeper occi- 

 pital groove, less rounded sides of the prothorax, and the 

 subparallel, less densely punctate, more shining elytra 

 separate M. egaensis from M . scabrida. 



52. Macratria truncata, n. sp. 



Elongate, robust, shining, sparsely clothed with rather long, 

 decumbent, cinereous hairs ; black, the palpi, mouth-parts, and legs 

 (the bases of the femora, the knees, and the posterior tibiae and first 

 tarsal joint excepted) testaceous, the two basal joints of the antennae 

 fusco-testaceous. Head large, subquadrate, broadly truncate at 

 the base, closely, minutely punctate, the occipital impression almost 

 obsolete, the eyes large; antennae slender, moderately long, 

 joints 9-11 elongated and thickened, 11 one-half longer than 10. 

 Prothorax long, broader than the head, oval, widest anteriorly, 

 obliquely compressed on the flanks posteriorly, the basal portion 

 dilated laterally, the basal groove shallow; densely scabroso-punc- 

 tate. Elytra wider than the prothorax, long, rather convex, sub- 

 parallel in their basal half, densely, confluently punctate, without 

 trace of striae (the sutural stria excepted) on the disc. Legs stout,
