wrinkled. Thorax a little longer than wide, widest at middle, base a little nar- 

 rower than apex, sides moderately arcuate, very feebly sinuate in front of the 

 hind angles which are obtuse, almost rounded, margin very narrow, disc slightly 

 convex, median line moderately deeply impressed, surface obsoletely transversely 

 wrinkled, a few obsolete punctures along the apical margin arid sides. Elytra 

 oblong, slightly wider posteriorly, longer than the head and thorax, strife moder- 

 ately deep, finely puhctulate, intervals slightly convex, sparsely obsoletely punctu- 

 late. Body beneath blue, smooth, shining. Length .32 — .40 inch ; 8 — 10 mm. 



Sexual characters as in punctata except that the anal segment of the female 

 is tripunctate. 



This species has some resemblance to viridipennis but is more brightly 

 colored, has a more narrowly margined thorax and with the base not 

 impressed above. 



Occurs in Georgia and Florida. 



C purpurea Say. —Form more robust, as in Philophuga amccna, color deep 

 blue or violet varying to green, moderately shining. Antennre as in fulgida. 

 Head sparsely punctulate, front vaguely impressed each side and rugulose. 

 Thorax as broad as long, base and apex equal, sides arcuate, a very feeble sinua- 

 tion in front of the hind angles which are obtuse, margin narrow, a little wider 

 posteriorly, disc moderately convex, median line impressed, surface transversely 

 wrinkled especially near the sides, a few punctures along the apical margin. 

 Elytra oval, slightly oblong, scarcely longer than the head and thorax, a little 

 wider posteriorly, sides moderately arcuate, disc finely striate, stria? punctured, 

 intervals flat or very slightly convex near the base, sparsely obsoletely punctulate. 

 Bod}' beneath smooth, shining. Length .30 — .36 inch; 7.5 — 9 mm. 



Sexual characters as in fulgida. 



For what reason Say's name purpurea has been heretofore applied to 

 a species now referred to the genus Philophuga, I can not understand. 

 In the Trans. Amer. Philos. Soc. 1823, p. 10, Say describes Cymindis 

 purpurea immediately after viridipennis, and of both he says, " penulti- 

 mate joint of tarsi bilobate," and in comparing the two species says, 

 " in form and magnitude resembles C. viridipennis but is more depressed 

 and wider." I think there can be no doubt that this species is the 

 true purpurea. .It greatly resembles Philophuga amcena in external 

 appearance, but the latter has the fourth tarsal joint emarginate and 

 not bilobed. 



Occurs in Michigan, Georgia, Missouri and Kansas. The specimens 

 from the latter region are darker blue in color, and I at one time referred 

 to them as a probable new species ; they do not differ otherwise. 



PHILOPHUGA Motsch. 



This genus contains those species in our fauna formerly placed in 

 Glycia. It is very closely related to Callida and differs in having the 

 fourth tarsal joint emarginate, not bilobed. An examination of the ligula 

 does not show any reason why Philophuga should be remotely separated
