segment, not as broad proportionally as in A. gibbosus; eyes moderate, 

 not prominent; antennae long and slender, basally enlarged. Pro- 

 notum large, elongate, much more so than in any other of the three 

 previously known species of the genus, produced caudad over the 

 base of the tegmina, only the costal portion of the distal margin of 

 the tegmina being visible from above; disk of the pronotum long, 

 narrow, and convex, without transverse sulci, subequal in width, the 

 cephalic margin subtruncate, the caudal margin strongly rotundato- 

 arcuate. Tegmina extending to caudal margin of pronotal disk, 

 the costal portion of the distal margin visible from above. Abdomen 

 not so heavy as in A. gibbosus, distinctly tricarinate above. Cerci 

 of the male short, heavy, subdepressed proximad, becoming strongly 

 so distad, proximal portion subequal in width, distal section bluntly 

 acute-angulate when seen from above; internal tooth placed slightly 

 distad of the middle, short, sharp, slightly recurved. Spination as 

 in A. gibbosus except in the case of the external margin of the posterior

Allotypic 9 . Taken in the low undergrowth of the pine woods; 

 other data the same as the type. 



Very little larger than the male, tegmina wholly concealed, caudal 

 limbs of the same general proportions, but slightly more elongate. 

 Ovipositor over one-quarter shorter than the caudal femora, as 

 heavy as in A. gibbosus, straight. 



General color broccoli-brown, face and antennse very light, broken
