fluently punctate a little below the apex a short transverse impressed line ; metasternum 

 longitudinally impressed at middle, coarsely punctate at sides, finer and sparser at 

 middle ; abdomen coarsely punctate at sides, sparser at middle, first segment some- 

 what depressed at base with a faint longitudinal median impression, reaching to the 

 middle of the segment ; last ventral segment truncate, a small, more or less prominent 

 apical tooth on each side. Legs, metallic green or aeneous. Length, 12-16 mm. 



Four specimens in the Museum of the Brooklyn Institute taken at 

 Esperanza Ranch, Brownsville, Texas. Of the same form as gracilipes, 

 from which it differs by the larger size, smoother, hardly impressed 

 prothorax, elytra very much more feebly sculptured, the more promi- 

 nent elytral spines, the remarkable smooth shining nearly unpunctured 

 prosternum at middle, very coarsely and closely punctured m gracilipes, 

 and the broadly emarginate clypeus which is in gracilipes triangularly 

 emarginate. 



Chrysobothris purpureoplagiata, new species. 



Elongate, feebly depressed, color bright green, elytra with more or less distinct 

 purple blotches at apical third, like Incana Horn, surface subopaque, very feebly 

 shining. Head densely punctured, an irregular arcuate smooth space at top of a 

 bright metallic red color; clypeus semicircularly emarginate, antennae cupreous, 

 slightly more slender to tip, third joint a little longer than fourth. Thorax about one 

 and a half times as wide as long, sides straight, slightly convergent to base, anterior 

 angles rounded, disk moderately convex, surface regular without any inequalities, 

 punctuation denser at sides than at middle, slightly strigose, at each apical angle a 

 more or less distinct cupreous spot. Elytra a little wider than thorax, parallel, very 

 slightly wider behind the middle, becoming narrower to apex at apical third where the 

 margin is coarsely serrate, apices obtuse, disk at about basal third with a faint rounded 

 fovea at middle, basal and infra-humeral foveae distinct ; surface somewhat coarsely 

 and asperately punctured at base, gradually finer towards apex. Body beneath simi- 

 lar in color but more shining, sparsely punctate, ventral segments without callosities, 

 margins of the last distinctly serrulate-prosternum lobed in front, coarsely and densely 

 punctate; anterior femur with a small, acute tooth, and a few denticulations exter- 

 nally. Length, 6-7 mm. 



Male. — Prosternum convex, coarsely and closely punctured, anterior tibiee slightly 

 arcuate, a short dilation near apex ; middle and posterior tibite straight ; last ventral 

 segment, semicircularly emarginate ; last dorsal slightly notched at middle. 



Florence, Arizona, 3 specimens received from Mr. G. Franck as 

 C. prasina Horn from which it is abundantly distinct. 



The even thorax and the serrulate last ventral segment place this 

 species in Dr. Horn's Group I, Titd,x purpureovittata, from which it is 

 distinguished by the somewhat subopaque surface, the semcircularly 

 emarginate clypeus and the slight median foveae of elytra. The 

 purple blotches are variable in size, they may extend to the base or
