species are in the hands of all the few American hemipterists, 

 it will be sufficient to state little more than the points in which 

 the new species differs from the others. 



Rheumatobates trulliger n. sp. Color as in Rh. tenuipes 

 Mein., the pale lozenge-shaped spot to the mesonotum of the 

 apterous form being narrower than the pale spot of the pronotum, 

 and the yellow mesosternum being marked with two longitudinal 

 black bands. Mesonotum of the apterous form in both sexes 

 somewhat broader than long. 



Male : The spongy fossa of the third antennal joint occupying 

 somewhat less than the apical half of the joint, being distinctly 

 longer than in Rh. Rileyi, but shorter than in Rh. tenuipes; fourth 

 antennal joint somewhat shorter than third, being conspicuously 

 longer than in Rh. Rileyi, but a little shorter than in Rh. tenuipes, 

 its spine placed in the basal half, but nearer to the middle than 

 to the base. Legs much as in Rh. Rileyi, but with the following 

 dift'erences. 



Rh. trulliger: 



Middle femora perfectly straight, 

 hairless from the base to near the 

 apex, where there are a few hairs 

 on the inner margin. 



Middle tibiae fringed with long 

 straight hairs on the inner side 

 from the base to beyond the middle, 

 then with short straight hairs. 



The curved hind femora scarcely 

 or slightly thicker in the middle 

 than at base and apex, with very 

 short and tiny hairs along the 

 whole inner margin. 



Hind tibise on the outer side be- 

 tween the middle and the apex with 

 a distinct spine and the apex filled 

 with a very thick tuft of rather 

 long hairs. 



Rh. Rileyi: 



Middle femora a little curved, 

 fringed with long hairs along the 

 whole inner margin, the longest 

 hairs being in the middle. 



Middle tibise fringed with short 

 hooked hairs on the inner side 

 from the base to near the middle, 

 slightlj' more than the apical half 

 hairless. 



The curved hind femora conspicu- 

 ously incrassated in the middle, the 

 inner margin of their basal third 

 densely fringed with rather long 

 hairs. 



Hind tibise on the outer side be- 

 tween the middle and the apex with 

 a minute (sometimes indistinct) 

 tubercle, the space between the tu- 

 bercle and the apex with very short 

 hairs, not forming a tuft. 



Female: At once distinguished from the female of RJi. Rileyi 

 by the black-banded mesosternum, but extremely similar to that
