This is a small, shining species placed by Stal in the genus Pamera. 

 Stal's description of the female only is rather meagre and fails to 

 indicate very common color variations. Though the head, anterior 

 lobe of the pronotum and scutellum as well as the fasciation of the 

 hemielytra may be blackish more commonly these parts with the 

 exception of the scutellum are j^ale castaneous or ferrugineous ; the 

 collar and the posterior lobe of the pronotum pale stramineous, punc- 

 tate with ferrugineous. The anterior femora and preapical part of 

 second and third femora most frequently are also ferrugineous. 

 Other important characters omitted by Stal are : the head is relatively 

 short, much as in Hcrccus, front much inclined, the eyes so placed that 

 the postocular space is al)out equal to the space beween apex of 

 antenniferous tubercles and eyes; head and pronotum sparsely setose; 

 first three segments of antennae pale, fourth uniformly darker; mem- 

 brane slightly embrowned with the apex and some spots toward base 

 pale ; fore tibia of males much curved basally and provided with a 

 stout tooth one third the distance from apex ; fore femora quite setose 

 and armed almost throughout with a single series of scattered un- 

 equal, relatively strong spines, one or two in the middle largest. 

 Length 4 to 4>4 mm.

After a careful study of Mexican material in the collection of 

 Mr. Torre-Bueno, I am fully convinced that my pscudohcrccns is a 

 synonym of Distant's species, as suggested by me in 1918. In the 

 Brownsville, Texas, material I had only females for study and thus 

 was unaware of the character of the fore tibia of the male. Mr.
