196 Mr. E. Saunders' Si/tiopsts of 



5. Coelioxys acuminata, Nyl. (PL VIIL, fig. 5). 



Nyl., (Kevisio) Not. Sails. Faun. Flor. Fenn., Forh., 

 ii., p. 279. 



Differs from elongata in the following particulars : — 



(^ . Has the apical teeth of the 5th segment rather more spini- 

 form, the upper apical spines of the 6th segment more divergent, 

 the 4th segment beneath as largely and remotely punctured as the 

 3rd (for genitalia see PL VIII., fig. 5). 



5 . Has the 5th abdominal segment without an apical fringe, 

 and the 6th rather longer and more pointed, the bands of the other 

 segments more widely interrupted; beneath the 4th segment is 

 largely and clearly punctured, although less coarsely than the 3rd; 

 the 6th segment is rather longer, the constriction less marked, and 

 nearer the apex in proportion to the entire length of the segment. 

 Length, 12 mm. 



Hab. Hastings, Deal, Norwich, and Colchester, and 

 probably common, but mixed with elongata. 



N.B. Mandihularis, Nyl., which F. Smith refers to 

 elongata, is a distinct species, with black calcaria and 

 geniculated mandibles ; but I do not know of its occur- 

 rence in this country. 



Megachile, Lair. 

 Latr., Hist. Nat. Ins., xiv., p. 51. 



Eyes not hairy ; ^ with the mandibles angularly produced at 

 the base ; anterior coxae generally with a long blunt spine on each. 

 Wings with two submarginal ceUs ; maxillary palpi 2-jointed ; 

 labial palpi 4-jointed. 



^ . "With the 6th dorsal segment terminating the abdomen like 

 a sort of cap, and bearing a well-marked apical crest, its posterior 

 margin inferior ; 7th dorsal segment inferior, and 8th dorsal in- 

 closed in the 7th ; four ventral segments only visible ; 5th with 

 an apical, central, more or less rugose, patch ; 6th very narrow, 

 and clothed across the middle with spine-like hairs, often recurved, 

 or widened at the apex ; apex of the segment often produced into 

 a membranous wing ; 7th so fragile and membranous that I have 

 been unable to extract it entire ; 8th narrow and tongue-like ; 

 genital armature very largo at the base, the stipites more or less 

 divergent, the sagittae narrow and pointed (for figures of armature, 

 see PI. IX). Anterior coxae each with a long, thick, blunt spine.
