cleft, dividing it into two lateral spines. The present form 

 differs further by the lateral border of the pronotum being 

 largely green, which may, however, occur in lynccn by the 

 enlargement of the green spot near the head, and by the slightly 

 longer opercula which extend to the end of the third abdominal 

 segment, the border of which is also more strongly reflexed. 

 Otherwise it comes within the range of variation displayed by 

 lynccn. 



Type : One male from Fernandina, Florida, collection U. S. 

 National Museum. 



This may be the species which Professor Osborn regarded 

 as the possible male of his fidvnla, since he speaks of the oper- 

 cula having "a distinct reflexed border," while in the true 

 fith'nla they are not more strongly reflexed than in other 

 species. 



Cicada canicnlaris Harris. 



Length. J 1 , 27-30 mm., to tip of wings 40-44 mm.; ?, 26-27 mm., to 

 tip of wings, 39-45 mm. The head and thoracic markings are much 

 like those described for fruinosa, but the extreme lateral mark of the 

 mesothorax rarely joins the sublateral one posteriorly. As a rule but 

 little variation is shown, though in a few specimens the two central 

 anterior marks combine, forming one large spot and each of the two 

 lateral marks join in a like manner. The posterior and lateral margins 

 of the prothorax are green, as in the entire background of the thorax, 

 and rarely, in heavily marked examples, there is a tendency for the 

 anterior portion to become black. Abdomen above black, with small 

 linear pruinose spots on the first segment in a few of the males only. 

 Beneath, the center is highly polished black, with broad white pruinose 

 borders. In the specimen from which the figure was made the pruinose 

 border was removed, which shows the major portion of the pleura 

 also black. The opercula in typical specimens are considerably 

 broader than long and are usually dark brown or blackish, though 

 variations run toward larger opercula which are also lighter in color. 

 The uncus of the genitalia is slender when viewed from the side, tapers 

 apically and is slightly swollen in the center. 



Habitat. From Nova Scotia and Lake St. George, Quebec, 

 westward to Wisconsin and Iowa and southward to Washing- 

 ton, D. C. ; mid-August to mid-October. 



This form probably occurs throughout the northern United 

 States east of the Mississippi River.
