Female. Length 3-4 lines. — Head black, pilose, with the vertex 

 and occiput fulvous ; antennae dark fulvous ; mandibles fulvous, 

 their tips black. Thorax fulvous, punctured, with a few scat- 

 tered black hairs ; legs rufous or rufo-fuscous. Abdomen 

 black, the base fulvous, and armed on each side beneath with 

 a fulvous tooth, which is bent obliquely downwards ; the mar- 

 gins of the second and following segments thinly ciliated with 

 white hairs. 



Male. Length 3 lines. — Black ; the head deeply punctured and 

 pubescent; the mandibles piceous, more or less red in the 

 middle. Thorax punctured, shining, and covered with a dense 

 griseous pubescence ; the metathorax rugose, with a smooth 

 space at its base of the form of an isosceles triangle, with the 

 sides a little rounded, and enclosed by an elevated ridge ; the 

 tegulae piceous; wings fuscous, then nervures rufo-piceous. 

 Abdomen with scattered punctures, shining, and covered with 

 long griseous pubescence ; the second and third segments have 

 a band of short grey pubescence on their apical margins. 



The claim of this insect to being indigenous is very doubtful ; 

 it is said to have been taken at Shooter's Hill ; but, unless con- 

 firmed by future captures, its being a British species requires 

 confirmation.
