neio Species of \\\?,\.Q,nt\-x'.. 897 



between thcc}-es, clypcus nearly straight in front, both thickly 

 and coarsely punctate ; thorax less coarsely and less densely 

 punctured, lateral stria well marked, especially at the anterior 

 angles, but extremely tine behind the neck ; scutellar spot 

 shallow; elytra punctured similarly to the thorax except in 

 the region of the scutellum, where the points are finer ; the 

 propygidium and pygidium are evenly and closely punctured, 

 punctures finer than those of the sterna; the inferior portion 

 of the pygidium is a little concave and is separated from the 

 upper and convex ])art by a transverse semicircnlar ridge; 

 prosternum, lobe distinctly marginateanteriorly, rather coarsely 

 punctate, posteriorly arched, not incised ; mesosternum punc- 

 tate like the prosternum, and immarginate anteriorly ; meta- 

 sternum with smaller and much less thickly-set punctures, 

 lateral stria oblique, median stria fine but faint ; anterior 

 tibia3with seven dcnticulations, intermediate with six, the tiiree 

 centre ones being close together and having a common base, 

 posterior 4-spinose. 



The species is less brilliant and more cylindrical than 

 T. ftstivum, Lew. 



Hab. Bahia. 



Teretriosoma cingulum^ sp. n. 



Cylindricum, viridiim, nitidum ; antennis pedibusque piceis ; meta- 



sterno stria laterali semicirculari. 

 L. 2 mill. 



Cylindrical, bluish green, shining above, nearly black 

 beneath ; head little convex between the ^y^^, evenly and 

 closely punctured ; thorax, stria complete, moderately strong 

 at the sides, feebly sinuate, and very fine behind the head, 

 punctured like the head, but the punctures are less closely set 

 on the disk in front of the scutellum ; elytra without strije, 

 punctured evenly like the disk of the thorax ; the propygidium 

 and pygidium are closely punctured, the pygidium being 

 moderately convex ; prosternum coarsely punctate, rather 

 deeply incised at the base ; mesosternum somewhat acutely 

 produced in front, with anterior stria complete ; the lateral 

 stria of the metasternum is semicircular, well marked, and 

 passes outwards behind the coxte, the median line is obsolete; 

 anterior tibife 6-7-dentate, intermediate 4-dentate. 



This species is more cylindrical than T. virens^ Mars. ; the 

 scape of the antennae is without hair, and the prosternum and 

 mesosternum are narrower, with the anterior marginal stria 

 of the mesosternum well defined, not obscurely so as in 

 T. virens. 



Ilah. Bahia.
