and it has been reported from Maryland and Hudson's Bay 

 {prasina). In this species the vertex and anterior part of 

 pronotum are pale yellow, the lines on vertex obscure 

 while the spots are distinct, while in the preceding species 

 the vertex and anterior part of pronotum are washed with 

 greenish and the lines are all dark and distinct. 



<? Draeculacephala floridana n. sp. Plate VI, Fig. 6. 



Resemhling DiollijJes in size and length of head, the ver- 

 tex slightly longer, the margin thicker, the apex acute 

 conical, upturned. Front and vertex mottled with brown. 

 Length of male, 6.5-7 mm.. 



Vertex acute conical, the lateral margins thick, one-fourth 

 longer than the pronotum, disc concave anteriorly, front in profile 

 broadly convex, the clypeus small, in the same curve. Pronotum as 

 in viollipes, elytra similar to reticulata, but with fewer reticula- 

 tions. 



Color; front and vertex mottled with light brown and pale, a 

 minute polished dot of light at the apex slightly margined with dark 

 brown, a light median line ending in an irregular spot in front of 

 the middle, the inner margin of the ocelli broadly white, frontal 

 sutures with black lines to the ocelli. Pronotum pale the disc, 

 omitting a median line, green. Elytra green, the margins and 

 nervures pale. 



Genitalia; male, ultimate segment nearly square, valve almost 

 concealed, plates a little longer than the segment, attenuately 

 pointed. 



Described from two males from Charlotte Harbor, Flor- 

 ida, from the Iowa State College collection (Van. D. Coll.), 

 through the kindness of Professor Summers. 



The long, brown mottled, upturned vertex will at once 

 distinguish this species.

Intermediate in form and size between floridana and'

 the pronotum. Color grayish cinereous, a dark wedge on 

 vertex. Length, 9 6 mm., 5.25 ^ mm.; width, L5 mm. 



Vertex broad, slightly convex, apex blnnt, not quite as long as 

 the pronotum, lateral margins rouudiug to the convex front. Front

 curve of the front. Pronotum broad, slightly angularly emarginate
