THE CANADIAN ENTOMOLOGIST. 



Metrobates hesperius Uhl. Muskoka Lake. On pleasant afternoons, 

 when the surface of the water was smooth, these insects would con- 

 gregate in immense numbers, closely covering an area of several 

 yards in extent. A breeze, sufficient to slightly ruffle the surface, 

 would quickly disperse them, but whither I failed to discover, as I 

 was unable to detect any along the shore. The majority of the 

 specimens taken were immature ; they differ from the adult in having 

 five, pale yellow spots in addition to the pronotal— one on the centre 

 of the metanolum, one above each anterior, and another before each 

 posterior co.xa. 



Salididce. 



Salda inicrstitialis Say. Common along the shores of the river and lake . 



HOMOPTERA. 



dead idee. 



Cicada canicular is Harris. The familiar shrilling of this species was 

 frequently heard in the heat of the day among the tree tops. 



Membracidce. 



Enchenopa bi/iotata Say. Apparently rare. 



Ccresa biibalus Fab. Common, but mostly of the small dark coloured 

 variety, with blunt thoracic horns. 



Ccresa diceros Say. Occasional. 



Telamona coryli Fitch. Abundant on the hazelnut. TJie females are 

 frequently of an almost uniform brownish-ferrugineous, with but slight 

 indications of the pale bands, thus approaching closely the next, from 

 which it probably is not distinct. 



Telamona iristis Fitch. Common with the preceding. 



Telamona fagi Filch. One example. 



Telamona reclivata Fitch. Three examples. Variable both in colour and 

 form of the crest ; this being sometimes sharply angled behind, or 

 again obtusely rounded ; and the posterior edge may be either slop- 

 ing or almost vertical. The present examples are very dark in colour, 

 the pale areas being much obscured by fuscous punctures. 



Carynota marmorata Say. Numbers taken from a small poplar bush 

 (probably F. grandidentata), on the uplands south of Bracebridge.
