CHRYSOMELID^. 



ORSODACNA, Latreille. 

 In the Ent. Mo. Mag. xxxiv. (2 Ser. ix.) 1898, 175, Mr. Champion 

 adds a European variety of 0. cerasi, L., to the British list, and, having 

 taken a considerable number at Ashtead, Surrey, gives the following- 

 table of forms of this species and 0. lineola, Panz., which are represented 

 in his British collection : 



0. lineola, Panz. 



1. Testaceous, with a dorsal vitta on the thorax, the head and breast, 



and sometimes the suture of the elytra, black. — 0. lineola, Panz. 

 (Ashtead, Surrey, female.) 



2. Entirely testaceous above, the breast sometimes infuscate (Ashtead, 



male ; Paisley, female). 

 8. Testaceous, the head and breast infuscate oriblack. — 0. nigrice2)s, Latr., 

 0. mespili, Lac. (Ashtead, Gravesend, Paisley, female.) 



4. Bluish -green, the shoulders of the elytra, and sometimes the sides 



of the thorax rufescent or fulvous. — 0. hiimeralis, Latr. (Ashtead 

 and Paisley, male.) 



5. Bluish-green, the sides of the thorax broadly, the base of the femora, 



and the tibiae, fulvous (Ashtead, male). 



6. Entirely bluish-green above. — 0. coei-ulescens, Duft., and 0. nema- 



todes, Lac. (Ashtead and Paisley, male.) 



Eight varieties are enumerated by Weise, one only of which, his 

 form C, is not known to Mr. Champion as British. It is black, with the 

 elytra testaceous, the lateral margins excepted, or entirely piceous 

 (0. nigricollis, 01., and 0. marginella, Duft ). Weisc does not appear to 

 have noticed that some of the forms are restricted to one sex only. 



0. cerasi, L. 



1. Upper and under side testaceous. — 0. chlorotica, 01., 0. fulvicollis, 



Panz. (Male; no definite locality.) 



2. Testaceous, the suture of the elytra at the base, and the under 



surface, infuscate or black. — 0. lineola, Lac. (Colefoi-d and Matlock, 

 male and female.) 



3. Testaceous, the apex of the elytra and the under surface blackish. — 



0. melanura, F. (Male ; no definite locality.) 



4. Black, the thorax and the front of the head rufo-piceous ; the legs 



obscure ferruginous. — 0. glabrata, F. (Matlock, Garneys, female.) 



0. cerasi may be easil)- distinguished from 0. lineola by the almost 

 glabrous and more sparsely punctuied upper surface ; as both species
