and markings it followed lines similar to those of the males of the 

 allied species above referred to and hereinafter described, and be- 

 cause I had taken it from the same tree (presumably its food plant) 

 from which I had taken females of what I believe to be the true flava. 

 Other examples of such males have been noted in other collections, 

 either unassigned or manifestly placed erroneously, though never 

 under flava. Since this paper was first drafted there has appeared 

 the review of the genus by Gibson and Wells above referred to, in 

 the course of which the species O. fraterna is described as new, 

 based upon three male specimens in the National Museum collection. 

 No female which might plausibly be assigned to fraterna has yet been 

 discovered so far as I can ascertain. A recent examination of the 

 type material has confirmed by suspicion that the authors of that 

 paper had before them what it is here suggested may prove to be the 

 male of Goding's O. flava. But pending more positive evidence that 

 it is the male of the latter, it may be advisable to retain for it the 

 name fraterna Gibson and Wells. 



It is now in order to describe the green Ophiderma which has been 

 confused with the true flava, and which is represented by a consid- 

 able series of both sexes before me. Inasmuch as the females are 

 most likely to be confounded with flava, I will select that sex for 

 the type. 



Ophiderma evelyna new species. 



Female. — Type: Slender, strongly hairy pubescent on face and pronotum. 

 Face little broader than long; clypeus rounded, but little surpassing line of 

 cheeks, the latter scarcely if at all sinuate. Pronotum long and slender apically. 

 Elytral hook slender, distinctly upturned at apex. Face and pronotum wholly 

 light green, the face paler. Elytra slightly infuscated at base and apex, nerv- 

 ures pale. Abdomen yellowish green above and beneath. Legs wholly yellow- 

 ish green, claws dark brown. Length 6 mm. 



Male. — Allotype: Smaller than female, slender; pubescence and structure 

 as in that sex. Face yellowish green, immaculate ; two minute dots at base of 

 vertex above ocelli. Pronotum comparatively short, not extending more than 

 half way between end of abdomen and apex of elytra; pronotal apex rather 

 broad ; color light reddish brown, darker posteriorly, anteriorly strongly washed 

 with yellowish green, concolorous with face, callosities black ; a broad arcuate 

 vitta from humeral angle to mid-lateral margin, a mid-dorsal spot, and a sub- 

 apical broad transverse vitta, yellow. Elytra hyaline, nervures brown, dark 

 smoky at basal third, broadly so at apex. Abdomen black above, margins of
