new Species of il'i&tei'idse. 397 



between the eyes, cljpeus nearly straiglit ia front, both thickly 

 and coarsely punctate ; thorax less coarsely and less densely 

 punctured, lateral stria well marked, especially at the anterior 

 angles, but extremely fine 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 

 propygidiutn 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 part by a transverse semicircular ridge; 

 prosternum, lobe distinctly marginate anteriorly, rather coarsely 

 punctate, posteriorly arched, not incised ; raesosternum 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 

 tibigewith seven denticulations, intermediate with six, the three 

 centre ones being close together and having a common base, 

 posterior 4-spinose. 



The species is less brilliant and more cylindrical than 

 T. festivuvij Lew.

Teretriosoma cingulum^ sp. n. 



Cylindricum, viridum, nitidum ; autennis pedibusque piceis ; meta-

 L. 2 mill. 



Cylindrical, bluish green, shining above, nearly black 

 beneath ; head little convex between the eyes, 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 striae, 

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 passes outwards behind the coxae, the median line is obsolete; 

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



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

 scape of the antenna; 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.
