scrobes and the adjacent portions of the eyes. The lateral lobes of 

 the pronotum have the general pattern of coloration 

 found in Atlanticus very pronounced, being shining 

 black, bordered on the ventral margin with ivory- 

 white, this border being wide cephalad, but narrowing 

 sharply caudad; the entire cephalic portion of the 



lobes suffused with olive-grav. The sides of the Fi f: 22- ^ 'Allan-

abdomen are marked on the first seven segments sp. Outline of 

 with triangular shining black maculations, these are Txfil cercus ' 

 large cephalad, but rapidly decrease in size ventrad 

 and terminate dorsad at the lateral carinse and ventrad at the margin 

 of the abdominal segment. The median carina of the abdomen is 

 necked with the same color, noticeably cephalad and gradually 

 disappearing caudad until absent on the ninth abdominal segment. 

 In coloration the female is very like the male except that the dorsal 

 portion of the head, pronotum and abdomen is faintly streaked with 

 bistre.

In addition to the type and allotype we have the following speci- 

 mens before us which may be considered paratypic: 



Homestead, Fla., March 19, 1910; one nymph probably in the 

 next to last nymphal stage. 



Miami, Fla., March 28, 1910; one nymph in the same stage. 



The specimens in the one-fourth grown condition taken at Miami, 

 February 6-9, 1904, and the still more immature individual taken 

 there on January 17, 1904, and recorded by the present authors as 

 Atlanticus sp., 47 are nymphs of the species here described. 



All of the specimens of this species, with the exception of the male 

 type, were taken in the low undergrowth of the pine woods, and there 

 is every reason to believe that this environment is the favorite 

 habitat of the species; the male type was captured while crossing
