FRED. C. BOWDITCH. 329 



tuation sparse except at the sides of the thorax where it is more evident 

 but not crowded, scutel aeneous, elytra strongly and regularly punc- 

 tate striate, aeneous bronzy black, with the third, fifth, seventh and 

 ninth intervals as well as the basal margin flavous, the fifth and 

 seventh joining at the rear of the convexity, the third and ninth 

 joined near the apex and continued to it, body beneath and legs dark 

 shining black green. Length 7-8 mm. 



Two examples, St. Catarina Liiderwaldt, also No. 420 

 marked " n. i. m." by Jacoby. 



Comes n.ea.r polychordia Er. but with one less flavous vitta. 

 The sides of the thorax are nearly straight behind and the 

 surface is noticeably dull, the color of the elytra is brown 

 and the thorax is greenish, the light vittas are wider than the 

 dark spaces, and the ninth noticeably the widest of all, the 

 sutural dark stripe is hardly contracted at the base, but be- 

 comes attenuated at the apex, which is attained by the con- 

 junction of the flavous vittae. 



Desmog'i'aiuiiia buckleyi nov. sp. 



Head black, dull shiny, rather thickly punctate, labrum rufescent, 

 antennse black with basal joints rufous, thorax black shining, punc- 

 tures coarse and crowded at the sides becoming sparse and fine on the 

 disk, scutel black, obsoletely channelled behind, elytra black, sparsely 

 gray sericeous, coarsely and diffusely punctate, punctures crowded at 

 the sides and somewhat obsolete behind, and more sparse on the disk, 

 each elytra with two red spots, one basal median, the other subsutural 

 post median, body beneath and legs black. Length 7\ mm. 



One example, Ecuador (Buckley), unnamed in the first 

 Jacoby coll. 



Nearly allied to rufofasciata Kirsch but the anterior elytral 

 spot in place of being transverse and almost median is 

 small, somewhat elongate longitudinally and strictly basal, 

 the rear spot is smaller and more rounded. The thorax is 

 distinctly foveate depressed in the coarsely punctate area at 

 the sides, the lateral edge is parallel behind, abruptly rounded 

 in front and with sharp pointed anterior angles, the thorax is 

 less punctured than in ridofasciata, and in the latter species 

 the elytral punctures are much more uniformly coarse and 

 crowded, the apex of the elytra is absolutely rufescent.
