T. lyricen var. engelhardti (Davis). 



Ent. News, xxi, 458, 1910. 



The pronotum and mesonotum are entirely black except a tawny 

 spot in the central portion of the former. This variety is the form 

 found in the mountains of Virginia, North Carolina, and Georgia, 

 which in the northern part of the range of the species is to be 

 occasionally met with near the coast.

 T. chloromera (Walker) sayi (Smith and Grossbeck). (PI. 

 v,6.) 



List. Homop., 143, 1850. 



This is not a common species in Connecticut, but is more 

 southern in its distribution, being the most plentiful species about 

 the city of New York. It is without the median shining longi- 

 tudinal band on the underside of the abdomen, present in lyricen, 

 linnei, and canicularis, and the opercula are very long, usually 

 about 10 mm. The eyes are less prominent than in the three 

 species mentioned, and the collar is usually black, with an olive- 

 green irregular spot near each humeral angle.

Tibicina Kolenati. 



The periodical cicada or "seventeen-year locust" is the sole 

 representative of this genus to be found in Connecticut. In addi- 

 tion to the characters given in the key to genera it may be added 

 that the first and second cross-veins of the fore wings are infus- 

 cated and that the first cross vein usually joins radius 3 quite far 

 back, that is, nearer the base of the wing than in the next genus. 

 The basal cell of the fore wing is very small, usually about 

 2.5 mm. in length.

 locust. (PI. V, I and 2; ^gg scars, PI. xix, 2.) 



Syst. Nat, Edn. 10, 436, 1758. 



In addition to being called ''periodical cicada" and "seventeen- 

 year locust," this species is sometimes known as the "red-eyed 

 cicada," or "red-eyed locust," because in life the eyes are conspicu- 

 ously red. The dorsum of the abdomen is black ; the membranes 

 at the base of all of the wings are deep orange, as are the costal 

 margins of the fore wings. The veins are more smoky or clouded 

 than in any other Connecticut cicada and there is often a clouded
