emarginate posteriorly, scutellum with a double keel medianly, 

 and a lateral one each side. Pronotum and scutellum feebly 

 carinate. Tegmina subcoriaceous, little longer than wide, pos- 

 teriorly roundly obliquely truncate; reticulate; costal cell gen- 

 erally broader than sub-costal cell, with many simple transverse 

 veins. Wings rudimentary. 



I. citscitticida, sp. nov.

Massila Walker. 



Alassila Walker 1862, Journ. Ent. J, 314. 



Allied to Anidova Mel., but with differently formed 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. 

 Costal cell narrow. Posterior tibiae with one spine. Tvpe sicca

There are two species very closely allied. 



T. Cubital clearly forked near the middle, subradial also 

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



la. Subradial indistinctlv forked zvalkcri, sp. nov. 



I. zvalkeri, sp. nov. 



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

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