202 Mr. E. Saunders' Synopsis of 



5. Megachile ericetorum, Lep. (PI. IX., figs. 6 — 6 a). 



Lep., Hist. Nat. Hym., ii., p. 841 =pyri7ia, Sm. (nee 

 Lep.), Cat. Brit. Hym., 2nd ed. p. 174. 



*' $ . Length, 5 — 6 lines. Black ; tlie face with bright golden 

 yellow pubescence ; on the vertex it is usually inore or less fuscous. 

 Thorax, the pubescence on the disk short and fviscous, on the sides 

 and beneath pale fulvous, frequently inclining to cinereous ; the 

 apical joints of the tarsi ferruginous ; the pubescence beneath the 

 tarsi fulvous ; the calcaria pale rufo-testaceous. Abdomen oblong, 

 the two basal segments with thin pale pubescence, the following 

 with fuscous ; the apical margin of all the segments with entire 

 fasciae of pale fulvous pubescence, and beneath densely clothed 

 with pale fulvous. 



" (^ . Length, 5 lines. The pubescence similar to that of the 



5 , but longer and more dense on the face, the apical segment of 



the abdomen deeply emarginate in the middle, and denticulate at 



the sides ; the 7th segment has a longish spine in the middle ; the 



anterior coxae have a blunt spine." 



I have not seen the British exponents of this species, 

 so have copied Smith's description ; but it is very dis- 

 tinct, and easily recognised by the pale tarsi of the 

 male and the prominent tooth or spine on the 7th seg- 

 ment, and by the long banded abdomen of the ? (for 

 genitalia see PL IX., figs. 6 — 6a). 



Hah. " This species has been captured at and near 

 to Weybridge, Bristol, and Southampton. It must be 

 very local. No one has been ascertained to have taken 

 it for some years past." 



Smith is, I think, clearly wrong in referring this to 

 pyrina, Lep., who says of the latter ^ " les 4 premiers 

 articles des tarses dilates, blancs en dessus." 



6. Megachile centuncularis, Linn. (PI. IX., figs. 5 — 6a)_ 



Linn., Syst. Nat., ed. x., i., p. 575; Smith, Cat. Brit. 

 Hym., 2nd ed., p. 172.

 crest of 6th abdominal segment almost entire ; 7th segment entire, 

 with a slight central tubercle ; J with the scopa bright orange-red.
