lowish") ; median line on vertex swollen near its apex but terminat- 

 ing in a fine point ("slender") ; scutellum with incised line and two 

 points before it black ("three points black"). 



The female from the Fort Lee district, N. J., is perhaps more 

 nearly typical, although in its length in proportion of the length of 

 vertex to the width across the eyes and in the markings on the scu- 

 tellum, it corresponds to the Texas specimen and it further differed 

 by the face having 12 arcs instead of only 10, but its color and mark- 

 ings were otherwise as described by Van Duzee. 



Female from Staten Island, N. Y. : in this the length of the vertex 

 is equal to that of pronotum and just half the width across the eyes; 

 on the scutellum it has an additional pair of black spots, triangular 

 and protruding from under the hind margin of the pronotum; face 

 with only 9 brown arcs. 



Female from Fort Myers, Florida, is the first one in which the 

 measurements, the proportion of length of vertex to that of the width 

 across the eyes and the length of pronotum is typical ; the color of 

 vertex, anterior pronotum and scutellum is rather bright and clear 

 yellow ; face with only 7 brown arcs. 



To sum up : All the specimens examined show a variation which 

 is not unusual in this group. The arcs of the face, however, are 

 subject to a rather greater variation. The green and yellow colors 

 vary from bright to dark dull. Most striking of all is, that the two 

 characters in which these four females all agree are not typical, 

 namely, the length 8 mm., type is 7 mm., and two points black before 

 the incised line on the scutellum, description mentions three points 

 here. 



As the male has been heretofore unknown it may be well to pre- 

 sent the following description (following somewhat Van Duzee's 

 method in describing the female) : 



Vertex and anterior margin of pronotum heavily marked with 

 black. Length 6 mm. 



Vertex acute, length (.76 mm.) about three fourths the length of 

 pronotum (which measures .98 mm.) ; its length one half the width 

 across the eyes (which is 1.48 mm.) ; surface behind the apex rather 

 well depressed. Clypeus tumid and rather strongly angled when 

 viewed from the side. Last ventral segment of male truncate; valve 

 triangular and plates long, curving inwards.
