 smaller, and easily recognised by the following cha- 

 racters : — 



^. Face clothed with yellow hairs ; 3rd joint of the flagellum 

 more than half the length of the 2nd ; cheeks not one-third of the 

 length of the eyes ; genital armature with the sagittse not serrate 

 beneath, each terminating in a sickle-like hook ; the squama and 

 lacinia very short and simple (the figure of the armature of 

 pratorum will serve equally for this species). Tibiae and tarsi 

 clothed with reddish hairs.

 the length of the eyes, the tongue not reaching beyond the basal 

 segment of the abdomen, and the hairs on the posterior tibiae 

 red instead of black. Length, ^ and $ 15 — 18 mm., 5 10 — 12 mm.
