22 HETEROMERA. 
26. Statira sobrina, 
Elongate, narrow, rather convex, moderately shining, fusco-testaceous, the head and the basal and apical 
margins of the prothorax reddish-testaceous. Head broad, with exceedingly minute scattered punctures 
(only visible under a strong lens), the eyes moderately large ; antenne( d ) reddish-testaceous, long, mode- 
rately slender, the apical joint about as long as joints 5-7 united; prothorax subcylindrical, about as broad 
as long, the sides obsoletely margined at the base and apex, moderately rounded anteriorly, and strongly 
constricted behind, the hind angles acute and very prominent, the basal margin raised, the surface 
sparsely and very minutely punctured ; elytra with rather deep intrahumeral depression, long, subparallel 
in their basal half, very finely punctate-striate, the striae becoming deeper towards the apex, the interstices 
flat, feebly convex towards the apex, the third with about eight (two or three towards the base and the 
rest between the middle and apex), the fifth with one or two (near the apex), the seventh with one (at 
the shoulder), and the ninth with two (at the apex), fine setiferous punctures, the apices obtuse ; beneath 
reddish-castaneous ; legs rather long, moderately slender, reddish-testaceous, the femora smooth and 
glabrous. 
Length 7 millim.; breadth 2 millim. (¢.) 
Hab. Mexico (coll. &. Bates). 
A single male example only of this inconspicuous species, without more definite 
locality, is contained in Mr. F. Bates’s collection. S. sobrina is chiefly characterized by 
its narrow elongate shape, fusco-testaceous colour, very minutely punctured head and 
thorax, and reddish-testaceous limbs; the third elytral interstice has about eight 
setiferous impressions (scattered between the base and apex), and the fifth and ninth 
have each one or two near the apex.. S. sobrina closely resembles S. trazuensis, but 
differs in its much broader head, stouter antenne and legs, and distinctly (but very 
finely) punctured thorax, and in the elytral interstices being rather convex towards the 
apex, the third having more numerous setiferous impressions. From pallid forms of 
S. limbata and 8S. vilis its more parallel shape and other characters sufficiently 
distinguish it. 
27. Statira ivazuensis. 
Elongate, subopaque, obscure testaceous. Head narrow, almost smooth, the cyes small; antenna» testaceous, 
stender, the apical joint ( ¢ ) a little longer than joints 9 and 10 united ; prothorax narrow, convex, the 
sides finely margined at the base and apex, much rounded about the middle, slightly oblique in front, 
and strongly constricted behind, the anterior angles a little prominent, the hind angles acute, the basal 
margin moderately raised and at the sides grooved within, the surface almost smooth; elytra with shallow 
intrahumeral depression, long, subparallel, finely punctate-striate, the striz becoming shallower towards 
the apex, the interstices flat throughout, the third and ninth each with two or three fine setiferous 
punctures near the apex, the apices obtuse ; legs testaceous, slender. 
Length 8 millim.; breadth 2 millim. ( 9.) 
Hab. Costa Rica, Volcan de Irazu 6000 feet (Logers). 
A single female example only. 8S. drazuensis resembles the pallid unicolorous form 
of S. limbata; it differs from it, however, in its proportionately narrower head and 
thorax (the latter with less rounded anterior angles), more slender antenne, and more 
parallel and longer elytra, the latter only having two or three setiferous impressions on 
the third and ninth interstices,
