 siones occupantibus), maculis quattuor ad marginem apicalem 

 lineisque transversis medio late Interruptis frontis castaneis 

 notatum, vertice paullo plus quam duplo latiore quam longiore. 

 Pronotum dense castaneo-conspersum, limbo apicali excepto 

 transversim subtiliter impresso-striolatum. Mesonotum stra-

 lobi genitales segmento genitali aeque longi, conjunctim

 setarum retro versarum pallidarum instructi. 



Whether a ny of the African species referred by Stål 

 to Thamnotettix belong to Ällophleps is impossible to know 

 from the descriptions, as Stål paid but little attention to the 

 tegminal venation in the Jassidae. At all events Ä. inspersa 

 can not be identical with any of Stål's species. 



Ällophleps seems also to be alhed to the Indian genus 

 Äliturus Dist., but the juga are differently constructed; the 

 tegminal venation is neither described nor does it appear 

 from the figure. The name Äliturus being preoccupied (Fair- 

 MAiRE, Coleoptera, 1902), I propose the name Bothrognathus 

 for the jassid genus. An other similar but less alhed genus is 

 Goniognaihus Fieb. (usually but incorrectly written »Gonia- 

 gnathus»). Also this name being preoccupied (Agassiz, Pisces), 

 I substitute the name Goniozygiim for it. The African jassid 

 genus Titia Stål (preoccupied by Meigen, Diptera, 1800) 

 may be called Titiella.
