238 HYMEA'OPTERA ACULEATA. 



spring, and generally distributed. The form with the 

 spinose cheeks in the ^ , and red spotted abdomen in the 2 

 {spinigera) is rarer, and occurs with it ; it has been taken 

 at Reigate; Hastings; Ventnor ; Tunbridge Wells; 

 Canterbury. Barhara ; (Kirby). Exeter ; Highgate ; 

 Esher; [Smith). Land's End; (Marquand). Maidstone; 

 {Frisby). The autumn brood (rosai) frequents briars, &e., 

 and has occurred at Hastings ; Bournemouth ; Reigate. 

 Shirley; [Bothney). Ilf racombe ; Sidmouth ; {Smith). 

 Colchester; {Harwood). Land's End ; [Marquand). 



I have no doubt of the identity of these three forms. 

 The comparative lengths of the antennal joints are alike 

 in them all, and different from all our other species. I 

 used to think that rosx was distinct from the spring form 

 by the entire apical ventral valve of the ^ , and the im- 

 punctate dorsal valve of the ? , but on examination of 

 many specimens I find that these characters vary, as I 

 have autumn rosie ^ with emarginate valve, and ? with 

 the dorsal valve distinctly punctured, therefore I unite 

 them without fear. From Panzer's figure and description 

 of amtriaca it is clear that he cannot have meant to 

 represent rosse, as he both figures and describes the 

 posterior segments ^as fringed apically with white hairs. 

 The spring form is frequently stylopized. 



A. florea, Fah. — Black. Head and thorax clothed in 

 the (J with ochreous, in the ? with brown hairs, antennte 

 in the ^ short, not reaching to the scutellum, fourth joint 

 not more than half so long as the third, and the vertex of 

 the head I'ather quadrate ; mesonotum dull, finely punc- 

 tured, puncturation closer in the ? , wings slightly dusky, 

 propodeum finely rugose ; abdomen shining, first segment 

 scarcely punctured, the rest clearly so, more finely and 

 closely in the ? , first and second segments in both sexes 

 more or less widely red at the apex, the remainder nar- 

 rowly testaceous at the apex, third and fourth in the ? 

 with an apical line of golden hairs, apical fimbria dark
