282 Mr. E. Saunders' Synojpsis of 



5 . Face short, transverse, clothed with pale fulvous 

 hairs. Mesothorax clothed with fulvous-brown hairs, 

 very finely rugulose and punctured. Scutellum rather 

 more shining than the mesothorax, punctured. Meta- 

 thorax finely rugose, clothed with pale fulvous hairs, 

 especially at the sides. Abdomen short, ovate, dull, very 

 finely rugulose and finely j)unctured ; basal segment with 

 a few pale hairs on each side at the apex, 2nd segment 

 with a widely interrupted apical band, 3rd and 4th seg- 

 ments with entire apical bands of short pale fulvous, or 

 sometimes nearly white, hairs, 5tli segment, except at 

 the base, and the 6th densel}' clothed with dark brown 

 hairs ; segments beneath narrowl}^ testaceous at the 

 apex, and fringed with pale hairs. Legs clothed with 

 pale hairs, intermediate tibiae with brown ; posterior 

 tibise and tarsi generally pale testaceous, but sometimes 

 dark ; scops golden. Length 8 — 10 mm. 



Hah. Common and generally distributed. Occurs in 

 April, and also often in the autumn. 



I regard couvexiuscula, Kirby, as only a stylopized 

 variety of this species.

This species is very closely allied to Afzeliella, but is, 

 I believe, clearly distinct by the following characters : — 



(? . Hairs of the face below the antennae silvery white ; 

 Brd joint of antennae longer than the 4th, or at least as 

 long. Mesothorax clothed with bright fulvous hairs, with 

 a larger, deeper puncturation. Abdomen without trans- 

 verse bands, deep black, with a very fine short white 

 pubescence, and only slight indications of apical bands 

 at the extreme sides of the 2nd and Brd segments ; apical 

 ventral valve somewhat truncate ; apex of posterior tibiae 

 and the tarsi testaceous. 



? . Larger than Afzeliella ; the face less transverse, 

 and clothed below the antennae with silvery white hairs. 

 Mesothorax and post-scutellum clothed with very bright 

 rich fulvous hairs. Wings rather dusky. Abdomen 

 more elongate, 1st segment less transverse, apical fasciae 

 of the 2nd and 3rd segments interrupted, and composed 

 of rather longer hairs ; apical fimbria bright golden ;
