which are removed from the eyes by a space distinctly less than a 

 transverse ocellar width, will separate mirabilis from the other mem- 

 bers of the subgenus. 



Description. — Male : 



Head: Length more than half width, 1.55(1.40-1.69) : 2.28(2. 12- 

 2.40); interocular width, 1.36(1.30-1.43); anterior margin fully semi- 

 circular, broadly reflexed juga surpassing clypeus and convergent or 

 contiguous in front of it; surface polished, with numerous strong, 

 radiating rugae and scattered minute punctures; ocelli very large, 

 separated from eye by space distinctly less than transverse ocellar 

 width; jugum ventrally shining, in large part finely punctulate; 

 maxUlary plate alutaceous, with scattered, vague punctures. Anten- 

 nal segments: I, 0.43(0.30-0.49); II, 0.30(0.26-0.34); III, 0.54(0.52- 

 0.56); IV, 0.52(0.50-0.56); V, 0.52(0.50-0.56). Bucculae less than 

 half as high as labial II; labium reaching bases of posterior coxae. 

 Labial segments: I, 0.94(0.91-1.00); II, 1.29(1.26-1.33); III, 1.16(1.10- 

 1.24); IV, 1.05(0.97-1.11). 



Pronotum : Length more than half width, 3.09(2.96-3.40) :5. 13(4.67- 

 5.42); lateral margin straight or slightly concave on basal two-thirds; 

 with 8 to 18 submarginal setigerous punctures; transverse impression 

 moderate, usually obsolete medially, marked by irregular, medially 

 interrupted row of coarse punctures; anterior lobe with broad, shal- 

 low, subapical impression, punctation restricted to broad, subapical 

 band and irregular lateral patch of few to many punctures ; posterior 

 lobe with few widely scattered punctures, especially in middle third. 



Scutellum: Length subequal to width, 3.30(2.93-3.61) :3.30(2.91- 

 3.60) ; disc polished, with widely scattered, coarse, sunken punctures. 



Hemelytron: Clavus and corium polished; clavus with one sub- 

 median row of punctures; mesocorium rather uniformly and closely 

 punctate except in smooth space along radial vein and in two rows of 

 close-set punctm^es paralleling claval suture; exocorium irregularly 

 and less densely punctate than mesocorium; costa with four to eight 

 setigerous punctures; membrane distinctly surpassing apex of ab- 

 domen. 



Propleuron: Alutaceous, with few punctures in depression. 



Mesopleuron: Lateral area shining, impunctate with few obsolete 

 rugulae. 



Metaplem-on: Lateral margin of evaporatorium straight or slightly 

 concave; lateral area polished, mipunctate. 



Legs: Anterior tibia dorsally with seven or eight stout, flattened, 

 blunt spines arising from blackened elevations; posterior tibia moder- 

 ately widened apically, greatest diameter less than that of anterior 

 tibia.
