49. Macratria scabrida, n. sp. (Plate LXIV, figs. 21, $, 

 genital armature; 21a, ditto, in profile.) 



cj. Elongate, robust, subopaque, thickly clothed with fine, ad- 

 pressed, brownish-cinereous pubescence, with numerous pallid erect 

 hairs intermixed ; nigro-piceous, brownish on the disc of each elytron, 

 anteriorly, the palpi, mouth-parts, antennae, and legs (a patch on 

 the femora, and the tibiae in part, of the posterior pair excepted) 

 ferruginous or rufo-testaceous ; the entire upper surface very 

 densely, finely punctate. Head short, transversely subquadrate, 

 broadly truncate at the base, the occipital impression broad, shallow ; 

 eyes moderately large, rounded, prominent ; antennae rather slender, 

 joints 9-11 thickened and elongated, 9 nearly twice as long as 8, 

 1 1 much longer than 10. Prothorax long, subcordate, broader than 

 the head, widest before the middle, obliquely compressed on the 

 flanks posteriorly, the basal portion rather prominent laterally, the 

 basal groove shallow. Elytra much wider than the prothorax, 

 long, narrowed from the base, without definite imjjressed lines (the 

 sutural stria excepted) on the disc, the minute punctures confluent, 

 the surface appearing uniformly scabrous. Legs stout ; basal joint 

 of the anterior tarsi broad, that of the posterior pair not very elon- 

 gate. Penis-sheath with the dilated outer portion oblong, broad, 

 spoon-shaped, and furnished with a slender, hook-like process at 

 the tip ; the lateral lobes of the aedeagus long, hook-like, angularly 

 dilated basally. 

 Length 5 mm. 



Hab. Brazil, Rio de Janeiro (Fry). 



One male, with the remarkable genital armature exposed. 

 Recognisable by the very dense, fine sculpture, the fine 

 pubescence intermixed with long, erect hairs, the reddish 

 limbs, the transversely subquadrate head, the rather promi- 

 nent eyes, the long, simple, subcordate prothorax, and the 

 posteriorly narrowed, non-striate elytra, the usual sub- 

 marginal stria being almost obsolete. Compared with the 

 somewhat similar M. cahescens, Champ., from Mexico, the 

 present species may be separated by the smaller, shorter, 

 more truncate head, with broader occipital impression, the 

 non-seriato-punctate elytra, and the shallower basal groove 

 of the prothorax.
