400 Mr. J. Walton on the genus Apion. 



tate, the interstices broad, flat and coriaceous : varieties occur with 

 the interstices more or less convex and transversely rugulose. 



Specimens of Ap. suhsulcatum of Marsham and Kirby sent to 

 Schonherr and Gcrmar were determined by them to be Ap. 

 j^thiops of Herbst. Gyllenhal and Schonherr's having adopted 

 the latter name upon the authority of Germar, has induced me 

 to follow them. 



Occasionally found in plenty in many parts of England ; near 

 Dover upon Vicia Sepium in June. 



68. A. livescerumS, Schonh.

Plumbeous black, glossy, sparingly clothed with fine cinereous 

 hairs. Head subquadi'ate, the vertex adjoining the thorax smooth, 

 the frons posteriorly slightly convex, closely punctured, between 

 the eyes commonly flat, sometimes depressed, longitudinally ru- 

 gose-punctate, with one to two impunctate strise more or less di- 

 stinct ; eyes prominent ; rostrum moderately stout, nearly as long 

 as the head and thorax together, cm'ved, a little attenuated in 

 front, rather thickly punctulated throughout, black and slightly 

 glossy. Antennae medial, rather longer than the rostrum, totally 

 black. Thorax very little longer than broad, subcylindrical, broader 

 behind than before, the anterior margin elevated, laterally scarcely 

 dilated, convex above, coarsely and thickly punctured, posteriorly 

 with a deep dorsal channel more or less abbre\aated in front, 

 plumbeous black and shining. Scutellum triangular, black. 

 Elytra long-obovate, the shoulders nearly rectangular, the hu- 

 meral callus elevated, convex above, deeply punctate-sulcate, the 

 interstices flat, transversely rugulose, sometimes coriaceous, green- 

 ish blue, rarely blue or blue-black. Legs moderately long, black.

The female differs in having the head narrower ; the rostrum 

 longer, slender, filiform and shining ; the antennre inserted be- 

 hind the middle of the rostrum. 



Dr. Germar sent me six insects ( c? ? ) with the name of Ap. 

 translaticium of Schonh., remarking that he had received this 

 species from M. Schuppel under that name, and from M. Aube 

 for Ap. livescerum of Schonh. ; and that Ap. Hedysari of Walton 

 likewise agreed \xiih them. I received a tyjiical specimen of Ap. 

 livescerum of Schonh. from M. Chevrolat, who informed me that 

 Ap. t7'anslaticium w?is synonymous. I have closely examined the 

 above-named foreign specimens, and I am convinced they are 

 identical with the British species Ap. Hedysari. 



Found in abundance in the chalk counties on the common 

 saintfoin {Hedysarum Onobrychis) from June to October.
