NOTES ON BRITISH GEODEPHAGA. 59 



the rule applies. It is B. guttula, Fab., which Stephens 

 describes, and my reference is given to his Works, though 

 the supposed types in his cabinet for the most part equal 

 biguttatum. Again P, maritimus is Rudd's species, and 

 described by Stephens as such, and I refer it to B. femo- 

 ratum, because (as I stated) I had seen Rudd's type, and 

 found that it belonged to that species. But M. Jacquelin 

 Duval assigns it to B. concinnum, after the types collect- 

 ively (and quotes Dr. Schaum's authority, who, however, 

 speaks of but one specimen as concinnum). For the sake of 

 consistency, our author ought likewise (with me) to have 

 referred it as a synonym to B.femoratum — as a synonym to 

 B. littorale, according to the types, because the Stephensian 

 representatives comprise these species also. 



Again, I refer P. decorus, Steph. Mand., to B. decorum, 

 on the same principle ; it is correctly recorded by Stephens 

 as British, though the representatives in his cabinet consist 

 of several species besides. Our author, on the contrary, re- 

 el's P. decorus to B. rvjipes, Dufts., always after these 

 delusive types collectively. But to be consistent again, he 

 ought likewise to have referred it as a synonym, in part to 

 B. nitidulum — to B. affine (species or variety) — to B. Sto- 

 moides (species or variety), and (with me) to B. decorum; 

 because the supposed types in the Stephensian cabinet do in 

 fact — 1 decorum (the first in the row, and therefore pro- 

 bably the true type), 1 Stomoides, 1 affine, and 3 nitidu- 

 lum ! ! ! Into what a jolly mess of confusion and repetition 

 would a synonymy founded consistently upon the types in- 

 volve us. 



Again, our author objects, that I refer P. agilis to B. mon- 

 ticulum, and, herein, that I am again in opposition to Dr. 

 Schaum, who refers it to decorum. I reply, that I so as- 

 signed it for the reason stated at the time — because P. agilis,
