from above of moderate length (3.5 mm.) ; strongly shouldered, 

 beyond the slioiilders serrate, the apical spine narrow; from a 

 side view the dorsal surface is flat, the ventral surface tapering 

 to the tip, except just beyond the anus two or three large ser- 

 rations cause a slight widening; ovipositor extending less than 



3 mm. beyond the tip of the cornus. 



Length of thorax including basal jilates 9 mm. ; of abdomen 

 14.5 mm. ; expanse of wings 54 mm. ; antennae 18 mm. ; front 

 wing l24.5 mm. ; posterior leg '20 mm. ; tibia 8 mm. ; metatarsus 



4 mm.; ovipositor 7 mm.; total length to tip of cornus 28 mm. 



This may be the female of apicalin. 

 Habitat : Arizona. 



T^^:)e : ■ A unique female in the collection of the American 

 Entomological Society.

This species is known with certainty only from the male. 

 Female specimens from the same locality were recorded by 

 Kirby as S. edwardsti, with the remarks that they were per- 

 haps the females of abbotii. Konow is wrong in assigning this 

 species to cyaneus, which does not occur south of New York, 

 and is different in coloration. I have not seen specimens. 



Distribution: Georgia. 



Sirex arcolatus (Cresson) Kirby 

 The alxlomen of the female is a more metallic and shining 



blue than in the foregoing species. 

 Konow considers apicalis as a synonym of this species, but 



the male described by him for areolatus is not what I consider 



to be the male of areolatus, described below. 



Westwood's figure, by the shape of the abdomen and cornus 



leaves no doubt but that his gracilis belongs here.
