Brachypterous form.^ — Ovate, obovate, or elongate-ovate, dark 

 brown to dark fuscous brown. Antenna brown with first two and 

 fourth segments blackish fuscous, III testaceous, sometimes also 

 fuscous, body beneath stramineous to dark fuscous. Length 2.00- 

 2.35 mm., width (elytra) 1.20-1.40 mm. 



Head short, armed with two, porrect, frontal spines; bucculae 

 closed or open in front; labium extending to end of sternal sulcus, 

 open at base. Pronotum tricarinate, each carina raised anteriorly 

 and composed of a row of fairly large areolae, the lateral carinae 

 slightly divergent posteriorly; paranotum moderately wide, entirely 

 biseriate or with some extra areolae anteriorly, front and lateral 

 margins jointly rounded, thus rounded at anterolateral corner. 

 Elytron with discoidal area long, slightly more than three-fourths as 

 long as elytron, boundary veins raised, longitudinally sulcate; costal 

 area uniseriate, sometimes ^vith a few intercalated areolae at base 

 and a little in front of apex; subcostal area as wide or slightly wider 

 than discoidal area, each three to four areolae deep in widest part. 

 Hypocostal lamina uniseriate. Hind wings absent. 



Macropterous form.^ — Oblong. Pronotum distinctly convex, 

 tricarinate; carinae less elevated than in brachypterous form, each 

 uniseriate, the lateral pair divergent posteriorly. Elytra much longer 

 than abdomen, sutural areas overlapping each other in repose; 

 clavus well developed, concealed under the backward projection of 

 pronotum in repose; discoidal area about five-sevenths as long as 

 elytron. Metathoracic wings long, functional. Other characters 

 similar to those in brachypterous form. Length 3.00-3.12 mm., 

 width 1.25 mm.
