twice as long as the penuhimate, inwardly rounded on the posterior 

 margin, and slightly produced on the middle; ovipositor large, longer 

 than the py gofers. 



Habitat: Rondebosch, C. P. (Stal: Mally). 



Penthimia vinula Stal. (?) 



Penthimia vinula Stal. Hem. Afr. IV. 108. (1866). 

 Penthimia vinula Stal. Afr. Vet. Ak. Forb. 98. 2. (1855). 

 Penthimia vinula Distant. Ins. Transi. 



Form and appearance of P. bella Stal. Color shiny black mingled in 

 parts with brown and white. Length 4 mm. Breadth 1.75 mm. 

 Vertex white but with black markings which are symmetrical along 

 a median line; length not equal to the width between the eyes; convex 

 anteriorly, the margin obtuse. Eyes large, chocolate colored, ocelli 

 black. Face strong, the frons prominent, about three times as long as 

 the clypeus; lorse about as wide as the clypeus; cheeks large; two large 

 prominent white spots on the face above the region between the eyes. 

 Pronotum black with many small white spots; a little longer than the 

 vertex. Pronotum and vertex transversely striated. Scutellum black 

 over the major part, with a few white spots at the base, a white spot at 

 the apex, and two large brown marks on the middle. Elytra fuscous 

 black; claval area with few white spots; corium with a clear area near 

 the base of the costal margin, a circular clear space at the apex of the 

 claval suture and three distinct clear spaces on the area of the ante- 

 apical cells. Abdomen brownish black above, black on the venter, the 

 edges of the segments showing as white hnes and the margin a little 

 lighter than the remainder. Male genitalia : last ventral segment black 

 on the middle, yellow at the borders, about equal to the penultimate in 

 length; valve yellowish brown, not as long as the ultimate ventral seg- 

 ment; plates black, longer than the valve, the tips sharp; pygofer longer 

 than the plates, black. 



Habitat: Cape Town (Mally), Transvaal, Pretoria (Dis- 

 tant), German East Africa: Amani, Bomole (Melichar). 



This species varies from the P. vinula figured by Distant, in 

 having white on the vertex, pronotum and middle of the 

 elytral disk. 



FAMILY JASSID^. 



The true Jassids are characterized by the position of the 

 ocelli, which are located on the anterior margin of the vertex 

 where it merges into the frons. The appended synopsis of 

 tribes, taken from Van Duzee, best illustrates the main 

 characters. 



The family is perhaps better known than any other of the 

 Jassoid division and the number of described species is far in 

 excess of the Bythoscopidse and TyphlocybidcC.
