202 THE CANADIAN ENTOMOLOGIST. 



Colour. — Grayish white, with a definite tawny tinge, vertex with the 

 ivory apex broadly black margined, four large quadrate fuscous spots 

 between the eyes and a triangular one between them and the apex, 

 fuscous. Pronotum with six or eight angular and usually transverse spots. 

 Elytra gray, with most of the nervures light, the cross nervures and reflex 

 veinlets broadly light and mostly heavily fuscous margined. Face varying 

 from black with a few pale arcs to black above and tawny brown below, 

 but in any case the fuscous markings extend the entire length of the front 

 on the sides. 



Genitalia. — Female segment short and broad, the lateral angles pro- 

 duced into large, triangular, slightly depressed ears, posterior margin 

 between the ears slightly convex, with a narrow median slit halfway to 

 base, the margins of which are usually produced into minute teeth, whole 

 posterior disc of segment shining, black. Male valve long, triangular, 

 stout, shining, the apex acutely pointed and slightly upturned, plates 

 smaller, polished, narrow, only appearing as ridges outside the long valve 

 and terminating as two finger-like projections fitting down into the inflated 

 pygofers. 



Described from one female from Jacksonville, Florida (Mrs. Slosson), 

 in the author's collection, and three males and six females from St. 

 Petersburg, Sanford, and Oaks, Florida, received from Mr. Van Duzee. 

 The long vertex, with definite quadrate fuscous markings and the three 

 small cells in the anteapical like the "three links," renders this a striking 

 and easily recognized species. 



Deltocephalus fratermis^ var. mejidosus, n. var. 



Smaller and paler than fraternus, with the fuscous spots on vertex 

 only faintly indicated in pale brown. Length, 3,5 mm. 



Vertex shorter than in the species slightly variable, but with the same 



form at apex and with the black margin around the ivory tip, reat of marks 



on vertex and pronotum reduced to pale brownish traces. Elytra as in 



fraternus or slightly shorter, venation the same except that in the shorter 



forms one of the "three links" may be obscure. 



Colour. — Grayish, washed with tawny, usually three black spots in 

 a line on the elytra still remain, one against the cross nervure to claval 

 suture, one against the "first" cross nervure and one against the apex of 

 the third apical cell. Face black above, with light arcs, shading out to 

 tawny below.
