16. GENUS TYLOPELTA FOWLER 



Tylopelta Fowler, B. C. A. II : i5 (1894). 



Characters : Closely related to the preceding genus but differing particularly in having the 

 dorsum strongly sinuate, often actually step-Uke. The body is robust and triangular, the pronotum is 

 angular in front and bears a percurrent median carina and two lateral carinae on each side. A single 

 short, heavy ridge appears on the metopidium above the eyes. The tegmina are short and broad, not 

 at all concealed by the pronotum, and have five apical and three discoidal cells. Fowler described 

 the cells of the tegmina as « less oblong » than in Erechtiahvit this character is not constant throughout 

 the genus. 



Type gibbera Stal.

17. genus LEIOSCYTA FOWLER 



Leioscyta Fowler, B. C. A. II : 14 (1894). 



Characters : Small, narrow-bodied insects which in general facies resemble those of the two 

 preceding genera but which differ from both in having only two discoidal cells in the tegmina and in 

 the metopidium smooth above the eyes. The pronotum is more elongate than in Erechtia or Tylopelta 

 and the dorsal margin is always straight. A percurrent median carina is present but the sides of the 

 pronotum are usually smooth or with not more than one ridge on each side. The tegmina are entirely 

 free, with five apical cells but only two discoidals and with a broad apical limbus. The head is sub- 

 quadrate and flattened with the ocelH very poorly developed. The first two pairs of tibiae are foUaceous. 



Type pallidifrontis Stal.
