Massila Walker. 



Massi/a Walker i(S62, journ. Ent. 1, 314. 



Allied to Ajiidora Mel., but with differently ftjrmed tegmina, 

 etc. 



Vertex very short, transverse, apically subtruncate, scarcely 

 extending beyond the eyes. Frons vertical, laterally rounded, 

 medianly carinate, width and length about equal, lateral keels 

 strongly elevated. Clypeus set somewhat deeply into the frons, 

 medianly carinate. Antennae very short. Ocelli distinct. Pro 

 notum simple, wider than head and eyes, anteriorly truncate in 

 the middle, posterior margin roundly excavate. Mesonotum 

 longer than head and pronotum together. Tegmina elongate, 

 more than twice as long as broad, irregularly reticulate ; interior 

 margin of clavus strongly arched, basal f of costal margin arch-- 

 ed, the apical third straight and subparallel with opposite mar- 

 gin of tegmina. apical margin subtruncate ; no subapical line.

There are two species very closely allied. 



T. Cubital clearly forked near the middle, subradial also 

 clearly forked a little nearer the apex sidnico, sp. nov. 



I a. Subradial indistinctly forked zva!kcn\ sp. nov. 



T. walkcri, sp. nov. 



Agrees fairly well with the description of M. sicca, except that 

 the transverse veins in the tegmina. specks in the reticulations.
