band extending along the hind margins of both pairs of wings. 

 It occurs earlier than the species thus far considered, being 

 essentially a June cicada. 



Only two of the seven or eight broods known to occur in the 

 northeastern United States have so far been reported from the 

 State. These are broods ii (1911-1928), which has been reported 

 from Fairfield, Hartford, Litchfield, Middlesex, and New Haven 

 counties, and is the chief seventeen-year cicada brood of the State, 

 and brood xi (1903-1920), which has been recorded from Hart- 

 ford County, also from Rhode Island and Massachusetts. A full 

 account of the occurrence of brood ii in 191 1 may be found in the 

 Report of the Connecticut Agricultural Experiment Station for 

 that year, page 296. 

 T. septendecim var. cassinii (Fisher). 



Proc. Acad. Nat. Sci. Phila., v, 272, 1851. 



A small form or variety of this species, known as cassinii 

 (Fisher), often occurs with the typical septendecim, and is usually 

 not distributed over the entire range of the appearing brood, but 

 is more local. It is generally darker beneath, the w-mark on the 

 fore wings is not so conspicuous and the eyes are more prominent 

 in many of the individuals, otherwise it is only to be distinguished 

 from septendecim by being about one-third smaller. 



Okanagana Distant. 



The head is small in this genus ; both the fore and hind wings 

 are hyaline with the basal cell of the former long and narrow 

 (about 3 mm.) ; the first and second transverse veins of the fore 

 wings are unclouded, the first usually joining radius 3 nearer the 

 middle than in Tibicina. The opercula are small and transverse, 

 and the uncus cannot be withdrawn into the abdomen. 

 O. rimosa (Say). 



Jour. Acad. Nat. Sci. Phila., vi, 235, 1830. 



This is the smallest species of cicada to be found in the New 

 England States and is quite generally distributed. Like the 

 seventeen-year species its first appearance is earlier than that of 

 the other five species, and in the Highlands of the Hudson it 

 emerges during the first part of June. The membranes at the base 

 of both pairs of wings are deep orange or red in color, and there 

 are also red spots on the head, pronotum and mesonotum ; the hind 

 border of the pronotum is red and each abdominal segment is also 

 bordered with red. The song is weak and reminds one of that 

 of some Orthopterous insect, like one of the smaller species of 

 Neoconocephahis, and is quite different from the "Pha-r-r-r-r-ach" 

 and other notes produced by the seventeen-year species. This 

 species has not been recorded from Connecticut, but will probably 

 be found in the hilly portion, as it occurs in both the adjoining 

 States of New York and Massachusetts.
