ferred to E. Irevipennis Say by Dr. Dohrn, LinnaBa Ent., vol. xiv. 

 p. 220, No. 3, is not the true type. Mr. Say's species was collected 

 in Philadelphia, and his description agrees with the common form 

 from that locality. The species of Dr. Dohrn is as yet unknown to 

 me, and will probably prove to be distinct from the preceding. 



The figure of Mr. Gray no doubt represents a male, while that of 

 Herrich-Schaffer is an obese female, full of maturing eggs. Speci- 

 mens in the latter condition are common late in summer, and present 

 a very gross appearanee, and seem very different from the clearly 

 colored virgin types found earlier in the season.

" Ploiaria simplicipes Say, MSS.," determined by himself. 



Clay-yellow, or dull ashy-fuscous; moderately stout. Head broad, 

 above almost flat, minutely granulated ; the lobes almost equal, the 

 posterior one subtruncated at base, each side of which there is a 

 group of more elevated granules ; the middle line grooved from the 

 base to a little before the transverse impressed line, the under surface 

 pale yellowish. Sides of the head infuscated, more coarsely granu- 

 lated, the eyes black, composed of few facets; process of the tylus 

 long, slender, acute at tip, projecting considerably in advance of the 

 labrum; rostrum reaching to the anterior legs, pale-yellowish, the 

 basal and second joints subequal, the apical one much longer, very 

 slender. Antennas very slender, the basal joint hardly thicker but 

 much longer than the second, third joint exceedingly short. Prono- 

 tum wider than the head, a little narrowed behind, emarginated on 

 the posterior middle, obsoletely roughened, pubescent, longer than 

 the mesonotum; pectus distinctly granulated; postpectus longitudi- 

 nally carinated. Meso- and metanotum each widened behind, both 

 shagreened and with a common ridge each side extending behind the 

 end of the scutellum. Scutellum trapezoidal, the narrow end behind. 

 Anterior legs robust, the femora compressed, pale testaceous, faintly 

 clouded with brown, almost white beneath, the teeth extending over 

 two-thirds the length from the tip, the posterior spine much the long- 

 est, white, tipped with black, three or four others not so long, and 

 with numerous short ones between ; the tibiae less than one-half the 

 length of the femora, faintly banded with whitish. Intermediate and 

 posterior coxa? conical, the trochanters knob-like; the intermediate 

 femora not as long as the abdomen, notapparently banded; the pos-
