he had but one male before him, he did not venture to give it a 

 name. I propose for our species the name (Gypsochroa) e men- 

 data and for the males with female antennae, form gynandrata. 

 The accompanying figures of the ^ genitalia illustrate the differ- 

 ences I have mentioned. 



It must not be assumed that my endeavor is to detach every one 

 of our American species from its old name. If genitalic dif- 

 ferences led to such conclusion, I should be ready to doubt their 

 availability. But they do not. As a case in point I may cite 

 Hydria nndulata Linn. I have examples of it from England and 

 from Bohemia, and there is absolutely no difference between 

 these and American specimens in form, venation, markings, color 

 variation, or in genitalia ! To the systematist there is a real satis- 

 faction, but where the parent stock of the species sprang, why its 

 wide distribution has not changed it in the least, as appears to 

 have resulted in so many other forms, are problems for the evo- 

 lutionist to solve. 



NEW NEOTROPICAL HETEROPTERA. 



By J. R. DE LA ToRRE-BuENo, White Plains, N. Y. 



Rutuba* gen. nov. : 



Head shorter than thorax, anteocular part seen from the side 

 equal to the postocular; antenniferous tubercles apically spined. 

 First joint of the antenrias more than twice as long as the ante- 

 ocular part of the head, beneath unarmed; first joint half as 

 long as the second. Thorax longer than broad at the base, 

 narrowing sensibly anteriorly, anterior angles armed with a long 

 spine. Anterior femora armed exteriorly (beneath with four 

 long spines, the three shorter ones furcate and the longest simple, 

 long, at apex of femora, and a number of smaller spines ; in- 

 teriorly toward the apex armed with a. very long spine. Anterior 

 tibiae one fourth shorter than femora, beneath interiorly with two 

 long spines and exteriorly with three. Last abdominal segment 

 in the males produced into two laterally diverging long spines. 



This genus is near Pnirontis Stal. 



* A gladiator of that name.
