NOTES ON BRITISH GEODEPHAGA. 61 



"well as myself pronounced it, without the shadow of a doubt, 

 to be pusillum ; and though Dr. Schaum and myself at any 

 rate agree, that L. assimilis and hamorrhoidalis, Steph., are 

 one species, and certainly not JB. assimile, our author de- 

 termines that they are two different species, and that hcemorr- 

 hoidalis shall be assimile, and the other doris : and, lastly, our 

 author " persists" in assigning P. viridiameus, Steph., to 

 JB. tibiale, though I confidently affirmed that it is a veritable 

 decorum. ; and such it as certainly is, as that JB. impressum, 

 Steph., is not the Fabrician species of that name, but, as Dr. 

 Schaum correctly stated, " an ill preserved specimen of B. 

 flavipes. 



The persistency with which our author adheres to his 

 preconceived opinions respecting these Stephensian types 

 would be beyond all praise, if those opinions were equally 

 correct ; but as the matter stands, I may perhaps be per- 

 mitted to express my surprise that, since Dr. Schaum and 

 -I differ, in some few instances, as to the identity of the said 

 types, after a careful examination and consideration of them. 

 -—that (I say) the possibility— just the mere possibility — did 

 not suggest itself to our author, that he himself might be in 

 .error, when, for the second time, he pronounced so decided an 

 opinion (antagonistic to one or both of us) as to what they 

 are — without ever having seen them at all.
