Bntish Hymenoptera. 175 



cl3^peus, its more truncate prothorax, with its more 

 prominent lateral angles and narrower pale stripes ; its 

 dark tegulse, sometimes with a citron spot posteriorly, 

 and the linear pale band of the 2nd abdominal segment. 

 Length 10 mm. 



Hab. Bare. Hampstead ; Bristol. Bm-rows in dead 

 bramble stems, from which it may be bred. 



4. Odynerus reniformis, Gmel. 



Gmel., Syst. Nat., i., pt. v., p. 2750. Fig. Herr- 

 Schaff., Faun. Germ. 173, 17 (coxalis). 



The characteristic features of this species are the 

 yellow tegulfe, post-scutellum, and lateral metathoracic 

 spots in both sexes, the long yellow spines on the inter- 

 mediate coxse of the ^ , and the yellow basal transverse 

 spot on the clypeus, and the wide abdominal bands of 

 the ? . Length 12 — 13 mm. 



Hab. Chobham, Surrey. 



Of this very distinct species only one ^ has occurred, 

 which I took myself at Chobham in June, 1876. I have 

 collected frequently in the same neighbourhood since, 

 but have never met with it again. Its yellow post- 

 scutellum and tegulae would distinguish it, even in the 

 net, from its allies. 



5. Odynerus basalis, Smith. 



Smith, Cat. Hym. Brit. Mus., pt. v., Vespidcs, p. 58 ; 

 Fig. Ent. Annual, 1869, fig. 1, front, fig. 



Black ; basal segment of the abdomen with a large 

 red spot on each side in the ^ ; almost entirely red in 

 the ? ; <y with only the last two joints of the antennae 

 recurved. 



<y coarsely punctured ; a spot between the antennae, 

 the clypeus, the scape beneath, a line in the lower part 

 of the sinus of the eye and a small spot behind each eye, 

 the prothorax in front, the tegulae, a double spot at the 

 apex of the scutellum, and an apical band to the first 

 five abdominal segments, pale yellow ; the 2nd abdominal 

 band slightly widened at the sides ; flagellum beneath, 

 1st segment of the abdomen at the sides and beneath, 

 and all the legs, reddish testaceous. Wings dusky. 

 Clypeus rather deeply emarginate at the apex. Legs 

 simple.
