 T. canicularis (Harris). (PL v, 5.) 



Rept. Ins. Mass., 175, 1841. 



This is the most common species of cicada in Connecticut and in 

 the New England States generally. It is found in pine woods and 

 in the deciduous forest. It most closely resembles Tibicen linnei, 

 but is generally much smaller with less prominent eyes and with 

 the tergum less shining black. The costal margins of the fore 

 wings are not as suddenly bent near the middle as in that species, 

 but present a more even curve. Also its song is different from 

 that of linnei, being much more shrill.

T. linnei (Smith and Grossbeck). (PL v, 4.) 



Ent. News, xviii, 127, 1907. 



This species has so far been reported only from the southern 

 part of Connecticut, and does not appear to be generally distributed 

 in the New England States, though occurring in some of the 

 counties of New York State immediately west of Massachusetts. 

 Its generally larger size, more prominent eyes and shining surface 

 of the dorsum of the abdomen, and above all the bent costal 

 margins of the fore wings, will serve to distinguish it from 

 canicularis.

T. lyricen (Degeer). (PI. v, 3.) 



Memoires iii, 212, 1773. 



Next to canicularis this is the most plentiful species of cicada in 

 Connecticut and has a considerable distribution in the New 

 England States. It may be separated from its allies found in New 

 England by its black collar (hind margin of pronotum), and the 

 tawny colors of the fore part of the pronotum and on the mesono- 

 tum. The legs are also tawny in color and the opercula are 

 proportionately longer (usually about 7 mm.) than in either linnei 

 or canicularis.
