212 Mr. W. L. Distant on Ilomoptt 



Allied to Taipinga, but differing principally by the venatioa 

 of the wings, which possess only Tour apical areas. 



Type, M. pulchella, Stal (Cicada). 



In this genus I include the T/Z>/ce/i [Quintilia) ahdominalis, 

 Stal, of which by the kindness of Dr. Aurivillius I have had 

 the opportunity to examine a co-type which possesses four 

 apical areas to the wings. Stal (Hem. Afr. iv. p. 37) writes 

 of this species : " Alee areis apicalibus numero varialibus, 

 tribus ; quattuor vel quinque '' ; but he appears to have been 

 misled by the striking similarity in colour and markings of 

 several African species belonging to different genera. These 

 I hope to figure in my ' Insecta Transvaaliensia.' 



Genus Peunasis. 



Prunasis, Stal, Rio Jan. Hem. ii. p. 22 (1858). 



Type, P. viridula, Walk. (Cicada). 



Stal, in his synopsis of the genera of Cicadid^e (Hem. Afr. 

 iv. p. 9, 1866), gives as a distinguishing character of 

 Prunasis : '* Alis areis apicalibus sex." This is erroneous, and 

 he had previously {supra) correctly given in his diagnosis 

 " Alee areolis apicalibus quattuor." 



Division Chlorocystakia. 



In this division the abdomen in the males is always more 

 or less inflated or dilated, with a central longitudinal dorsal 

 ridge, and longer than the space between the apex of head 

 and base of cruciform elevation ; the head (including eyes) is 

 a little narrower than base of mesonotum; tegmina always 

 longer than body, their greatest width only about a third of 

 their length. 



Synopsis of Genera. 



A. Tegmina with eight apical areas. 

 a. Wings with six apical areas. 



b. Opercula in male of ordinary structure. 



c. Lateral margins of pronotum obliquely 



straigbt, posterior angles very slightly 



ampliate. 



d. Head with front not produced aud 



much broader than long, margins of 



front and vertex continuous Stagira. 



dd. Head with front much subconically 

 produced, as long as broad at base.
