mesothorax. Abdomen slightly shining, finely and 

 rugosely punctured, clothed with pale hairs on the lirst 

 two segments, and with black hairs on the remainder ; 

 each segment to the 5th with an apical band of pale 

 ochreous hairs ; 6th and 7th segments entirely clothed 

 with brown hairs ; beneath clothed with long pale hairs ; 

 apical ventral valve rounded at the apex, and slightly 

 and narrowly emarginate in the centre. Legs clothed 

 with ochreous hairs ; tarsi piceous. 



? . Face clothed with fulvous-brown hairs. Vertex 

 with black-brown ; mesothorax dull, closely punctured, 

 clothed with dusky brown hairs on the disk, and with 

 fulvous-brown hairs round the sides. Scutellum rather 

 shining, and remotely punctured. Metathorax finely 

 rugose, clothed with long fulvous-brown hairs. Abdomen 

 finely and very closety punctured, the puncturation of 

 the basal segment rather less close than that of the 

 following ; the 1st to the 4th segments with an apical 

 band of pale fulvous hairs fading to white, that on the 

 1st often wanting; 5th and 6th with long black hairs; 

 apical valve punctured, its margin very slightly and 

 narrowly reflexed ; segments beneath fringed at the 

 apex with bright fulvous hairs. Legs, especially the 

 posterior tibiae, clothed with bright fulvous hairs. 

 Length 10 — 12 mm. 



Hah. A very common species ; it appears in April, 

 and again sometimes in August. Extricata, Smith, 

 is only a variety with white bands, and is quite distinct 

 from the following, although often regarded as the same 

 by continental authors.

Very like the preceding, but differing in the following 

 particulars : — 



The pubescence of the face in both sexes is white, also 

 that of the under side of the thorax and femora ; the 

 abdomen in the <? is clothed with rather longer pube- 

 scence than in fulvicrus, and the apical bands are formed 

 of longer less decumbent hairs ; the puncturation also is 

 more distinct, and the genitalia lack the notch-like 

 sinuation on the outer margin near the apex observable 

 in fulvicrus. The ? has the abdomen rather more
