264 Mr. E. Saunders' further notes on the 



also by Professor Perez, ' Contr. a la Faune des Apiares 

 de France,' p. 89. 



Anthidium. — Apical segments very variable in form ; 

 8th sometimes with a narrow apical process, sometimes 

 tongue-like, as in MegacJiile ; 7th sometimes rounded at 

 the apex, with long recurrent basal angles, sometimes 

 merely a transverse band with short recurrent angles. 

 In strigatnm, Pz. = contractum, Latr,, the 6th segment 

 is produced into a strong central spine, and in fiavilahre, 

 &c., has lateral comb-like processes (see PI. XIII., fig. 

 15 rt) ; armature with the stipites short and curved in- 

 wards at the apex in some species ; in laterale, on the 

 other hand, they are slightly divergent, and approach 

 more to MegacJiile in form ; in strigatnm they are 

 foliaceous ; and in flavilahre widely triangular. These 

 segments evidently exhibit strong specific characters in 

 this genus, and would probably serve well to divide it 

 into subgenera (see PL X., figs. 3-3 a ; PI. XIII., figs. 

 15—15 a). 



Stelis. — 7th and 8th ventral segments simple, the 8th 

 being very slighily produced and rounded in the centre ; 

 armature with the stij^ites each suddenly thickened at 

 the apex into an angular, four-sided, truncate club, bent 

 inwards towards each other ; sagittae simple, slightly 

 convergent (see PI. X., fig. 2). 



Chelostoma florisomne. — 7th ventral segment bilobed ; 

 8th triangularly elongate ; armature with the stipites 

 long and straight, enlarged at the apex of each into a 

 pointed club, hairy on its sides ; sagittas straight, con- 

 vergent at the apex, with a central membrane extending 

 to their apex ; 5th segment fringed with curved spirally 

 twisted or knotted hairs (see PI. X., figs. 4 — 4 a). 



C. campanularum. — This s^Decies, in the terminal seg- 

 ments, shows very distinct characters ; the 7th segment 

 has a slight pilose production on each side, united by a 

 thin membrane ; the 8th is short and subtruncate ; the 

 armature has the stipites very narrow and curved, not 

 thickened at the apex ; the sagittae wide at the base (see 

 PI. X., figs. 5—5 h). 



Heriacles. — Very like C. campanidarum in the form of 

 the armature, but the 8th ventral segment is narrow and 

 pointed ; the 7th I have not been able to extract satis- 

 factorily ; 5th segment with a row of six or seven teeth 

 on each side set on a square projection (see PI. X., 

 figs. 1,1a)-
