apex), and the ninth with four or five (towards the apex), fine setiferous punctures, the apices obtuse ; 
legs piceo-testaceous or testaceous. 
Length 64 millim.; breadth 13 millim. (¢-) 
Hab. Mexico, Ventanas in Durango (Hoge). 
Two examples. A small, narrow, unicolorous species, not very closely allied to any 
other known to me. It resembles S. angustula in size and shape; but the thorax is 
relatively longer, and the elytra have more finely punctured striz, and more numerous 
setiferous impressions on the third, fifth, and seventh interstices. 
17. Statira metallica. (Tab. I. fig. 13, ¢ .) 
Elongate, reddish-castaneous or brownish-piceous, shining, the elytra eneous or greenish-geneous and some- 
times cupreous in tint at the sides towards the apex. Head rather sparsely and irregularly but quite 
distinctly (subrugulosely at the sides in one or two examples) punctured between the eyes and posteriorly, 
the latter large; antenne moderately long and rather slender, ferruginous—the apical joint in the male 
very elongate, nearly equalling joints 6-10 united, in the female shorter and about equalling 7-10 united ; 
prothorax rather longer than broad, the sides much rounded anteriorly, very strongly constricted behind, 
and obsoletely margined at the extreme base, the hind angles sharp and very prominent, the base broadly 
margined and the margin raised, the surface closely but exceedingly minutely punctured ; elytra with 
shallow intrahumeral depression, long, widest behind the middle, subparallel towards the base, finely and 
shallowly punctate-striate, the punctures very closely placed, the interstices flat or very feebly convex, 
the third with five (all placed beyond the middle), the fifth with about six (scattered between the base 
and apex), the seventh sometimes with one (close to the apex), and the ninth with about three (towards 
the apex), moderately coarse setiferous punctures, and the first deeply impressed within the sutural angles, 
the latter obtuse; beneath brownish-piceous, very shining ; legs piceous or ferruginous, rather slender. 
Length 113-122 millim. ; breadth (at shoulders) 33 millim. (¢ 9.) 
Hab. Nicaragua, Chontales (Belt); Costa Rica, Irazu (Rogers). 
Three female examples from Nicaragua and a male from Costa Rica. 
Var. The seventh elytral interstice with three setiferous punctures near the apex; the antenne fusco- 
ferruginous. 
Hab. Panama, Bugaba (Champion). A single male example. 
This species is chiefly distinguished amongst its allies by the distinctly and irregularly 
punctured head and the closely and very minutely punctured thorax. The simple 
anterior tibize and femora separate it from S. glabrata &c. The presence of a setiferous 
puncture on the seventh elytral interstice at the apex is a variable character, it being 
altogether obsolete in one example; the variety only differs from the type in having 
two additional punctures on the seventh interstice. The apical joint of the antenne in 
the male is very elongate. The cedeagus of the male is of peculiar form :—the apical 
portion of the central sheath is spoon-shaped, and on either side of this, and just 
behind it, is a stout hook curved upwards; in S. glabrata the sheath is gradually 
narrowed to the end and unarmed, and the apical portion is much more elongate. 
18. Statira inconstans. (Tab. I. fig. 14, @ var.) 
Elongate, brownish-piceous, the elytra greenish-aneous, shining. Head sparsely and minutely punctured or
