94 BEITISH CICADA. , 



mental spots. Pronotum acute-semicircular, with a 

 nearly straight posterior edge, slightly emarginate. 

 An irregular brown streak on each side. Three reddish 

 yellow parallel streaks pass from the upper edge of the 

 crown, and these are continued down one-half of the 

 pronotum. Scutellum whitish, with three red streaks 

 above and tv/o below. Elytron hyaline at the tip, with 

 a brown spot at the point of the clavus. Four or more 

 spots cross the corium, and sometimes these tend to 

 make an oblique bar. Limbus rather wide. Apical 

 cells four, large and irregular in form and size. Dis- 

 coidal cells two, and unequal in length. Wings large, 

 with a peripheral border ; the first nervure not forked 

 to this border. Abdomen cylindrical, brown, with 

 yellow-bordered segments and side edges. Genital 

 valves of the male small, and obtusely rounded at their 

 apices. Legs pale yellow or greyish. Hind tibiae with 

 brownish tarsal points. Hind femora with black knees 

 and greyish in tint. Setae yellow. Face pale yellowish. 

 Frons grey, and marked by eight obscure spots. Ocelli 

 distinct, and placed at the upper margin of the frons. 

 Antennae rise from shallow fove^, below greyish 

 patches. Genae semicircular, and bordered with 

 brown streaks. Clypeus oval. Eostral sheath short. 



The above synonyms are those given by Dr. Sahl- 

 berg, who notes two varieties the characters of which 

 mostly relate to colour-differences and markings. 



This insect appears to be the sole European species of 

 the genus as yet described. How far it differs generic- 

 ally from Limotettix I am unable to say. The figures of 

 the wings in Sahlberg's * Ofversigt ' do not show any very 

 clear departure from that genus ; but as he has not given 

 a lettered nomenclature to the nervures of the wings he 

 engraves, his descriptions are not very easy to follow. 



As to the habitat of this insect, Mr. Edwards says, 

 " Obtained by sweeping in summer, and beating firs in 

 winter and spring ; and not very common." 



As before noted, this insect at first sight appears to 

 be very like to Limotettix variata.
