from females of devius in being less robust, with narrower vertex 

 of the fastigium and narrower ovipositor jaws, and in having the 

 lateral lobes of the pronotum less deep and the post-ocular fuscous 

 stripe there pronounced, narrow and sharply defined from the pale 

 ventral portion of the lateral lobes. 



The males and young recorded above from Georgia could not be 

 assigned to this species were it not quite certain that M. devius is 

 found in Georgia only at the highest elevations in the Appalachians. 



Specimens before us from New York, New Jersey and Pennsylvania 

 are rather small and the males have the subgenital plate and preceding- 

 ventral abdominal segments wholly immaculate; this coloration is 

 found in but a single southern male which is from Clayton, Georgia. 



The northernmost specimens here recorded were taken along the 

 edge of a deciduous forest adjacent to a barren serpentine outcrop 

 (Pink Hill) and among low bushes on sandy soil (Beltsville). In 

 Georgia the species was found very locally in the undergrowth of 

 forests composed chiefly of deciduous trees, particularly on hillsides. 



The species was previously known from Staten Island, New York, 

 Stafford's Forge, New Jersey, and Sharptop Mountain, Georgia.

H.), 3 <?, 13 juv. cf, 13 juv. 9 . VIII, 22, 1913, (J. C. Bradley), 1 9 . 



The difficulty of separating males of this species from those of 

 M . tribulus is remarkable, considering that the females of the two 

 are very different, in devius being more robust, with broader fastigium 

 of the vertex and broader ovipositor jaws, with lateral lobes of the 

 pronotum deeper and the post-ocular fuscous stripe not sharply 

 outlined there, the lateral lobes being wholly infuscated with the 

 dorsal portion broadly darkened. 



The series from Charlotte and Spartanburg were found by careful 

 search in local areas of the rather scant undergrowth of the heavy 

 deciduous forest. The species was previously known from Wythe- 

 ville, Virginia, and Topton, Asheville and Mount Pisgah, North 

 Carolina.

The present insect may be readily separated from its allies by the 

 very peculiar subgenital plate of the male, which has a greatly devel-
