This is the Orontes of Mr. "Walker's catalogue, but is quite distinct 

 from the Orontes of Linnaeus and Clerck .

ApJiodiusporcus, a cuckoo parasite on Geotrv/pes stercorarius. — Last autumn, I ex- 

 amined the economy of Geotrupes stercorarius in the matter of oviposition,and in doing 

 so met with the unexpected fact that Aphodius porcus was parasitic upon it. As such 

 a habit must be regarded as a highly abnormal one in a LamelHcorn beetle, and 

 consequently requires a considerable amount of proof to establish it, I have given 

 my observations somewhat fully, and have added an account of the oviposition of 

 Geotrupes stercorarius, both because it is necessary towards understanding the 

 proceedings of Aphodius porcus, and because, though supposed to be known by 

 everyone, no one appears to be acquainted with the details of it, nor have I been
