Fieberian Catalogue, I have returned, and have left Professor Berg to 

 deal with them as he sees lit in his forthcoming volume of Addenda, 

 with the exception of the following : — 



Family DELPHACID^S. 



ECTDES FUSCO-YITTATA, 11. Sp. 

 $ . Pitchy-brown. Head : crown pale brown, pale straw-yellow at the base ; 

 frons and face pitchy-brown ; keels pale brownish-yellow, lower margin concave, 



omewhat yellow : clypeus brownish -yellow : antennce yellowish or pale brownish- 

 yellow, 2nd joint granulated. Pronotum shining, pale straw-yellow, sides brown 

 from a little way beyond the extremities of the keels. Scutellum shining, pitchy- 

 brown. JElytra clear, transparent ; corium : nerves yellowish, finely granulated, 

 nerves of the apical areas black, finely gi*anulated ; clavus with a longitudinal brown 



treak down the area, enclosed between the anal nerve and suture, apex of the area 

 enclosed between the anal nerve and dorsal margin with a short black streak. Legs 

 yellow. Abdomen above black, three or four terminal segments on the sides broadly 

 yellow. Length, 2£ lines. 



I have only seen a single female example which, by the character 

 on the elytra alone, differs from all the species known to me. 



The insect described by Professor Berg under the name of 

 Liburnia nimhata, has really nothing whatever] to do with the genus, 

 nor, indeed, with any of the other genera of Delphacidce, and I have, 

 therefore, characterized it as follows : — 



BEKGIA, n. g. 



Head : crown barely twice as long as broad, with a longitudinal central, and 

 two short keels, in front, the latter almost joined in the middle of the anterior 

 margin : face nearly equal in length to the breadth between the antennae, with two 

 longitudinal keels slightly widening from the lower margin of the frons to the apex j 

 clypeus about as long as broad, measured across the base, without a central longi- 

 tudinal keel ; antenna : 1st joint about half the length of the 2nd ; eyes somewhat 

 large. Pronotum with a central longitudinal, and two side, keels, posterior margin 

 concave across the scutellum. Scntellum triangular, apex acute, with five longitu- 

 dinal keels, the central one not reaching to the apex, and the side ones vanishing 

 before reaching the side margins. Elytra as in Cixius, Oliarus, &c, but the furcate 

 apical areas are longer than in these genera. Legs : tibia, 3rd pair with three spines 

 on the outer margin, nearly equidistant from each other, placed, one at the base, 

 another before, and the 3rd beyond, the middle j tarsi : 3rd pair, 1st joint almost 

 twice as long as the 2nd. 



This genus appears to be one of the connecting links between the 

 Delphacidce and the Cixiidce. The head is somewhat similar to Euides, 

 as viewed from above, but the broad face with its two keels completely 

 shuts out any relationship with that genus. The scutellum with five 

 keels brings it near to Oliarus, but the face here is also totally different
