Two specimens, assumed to be sexes, one having a longer 

 apical joint to the antennae than the other. Closely related 

 to S. agraeformis, Champ., from Panama (figured in 

 B.C.-Am., Coleopt. IV, 2, pi. 1, fig. 7), the head not so broad, 

 the eleventh aatennal joint in ^ shorter, the elytra with 

 narrower, smaller tubercles (and the striae, in consequence, 

 less sinuous), the legs infuscate, etc. S. agroides, S. gcm- 

 mifer, and S. catenata are somewhat similar forms, all of 

 them superficially resembling the Carabid-genus Agra^ 

 which is numerous in species in the same regions. 



11. Statira mucronata, n. sp. 



Elongate, widened posteriorly, shining; varying in colour from 

 nigro-piceous to castaneous, the antennae more or less infuscate and 

 with at least the apical joint ferruginous, the elytra in the darker 

 examples brassy or greenish -aeneous ; the elytra with numerous 

 bristly hairs. Head rather closely punctate, deeply, broadly 

 foveate between the eyes, the latter very large, somewhat narrowly 

 separated; antennae stout, moderately long in (J, shorter in $, 

 joint 11 in cj equalling 6-10, in $ 8-10, united. Prothorax longer 

 than broad, slightly narrower than the head, feebly rounded at the 

 sides, constricted before the prominent basal margin; closely, 

 conspicuously punctate, the interspaces polished, the disc trans- 

 versely depressed on each side anteriorly and also excavate in the 

 centre at the base. Elytra long, widening to beyond the middle, 

 more than twice the width of the prothorax, mucronate at the tip ; 

 finely, deeply puncta to -striate, the striae strongly undulate towards 

 the sides and apex, the interstices convex, 3, 5, 7, and 9 throughout 

 their length, and 1 at the apex, with a scattered series of setigerous 

 impressions, the spaces between them longitudinally tuberculate, 

 the tubercles on 7 and 9, and those towards the apex on 1, 3, 5, 

 shorter and more closely placed than those on the disc. Femora 

 moderately thickened. 



Length 10-12, breadth 3|-4L mm. ((^$.) 



Hah. Brazil, Ceara {GouneUe). 



Three males and three females, two only with metallic 

 elytra. Very like S. nigrocaerulea, but with the alternate 

 elytral interstices 3, 5, 7 and 9 here and there tuberculate 

 throughout their length, the tubercles on 7 and 9 shorter 

 and more numerous, much as in S. tuberculata, Makl. ; the 

 prothorax longer and a little more finely pimctate; the 

 antennae slightly stouter.
