Boseri. The typical form, according to Fieber and Flor, has the head, 

 pronotum, antennae, and scutellum black. Dr. Fieber also points out 

 to us in a letter that the Oapsus saliceticola of St^l is a variety of the 

 above with black pronotum and elytra.

Length (^ li, ? I line. 

 Mr. T. Wilkinson, after whom we name the species, has met with 



it in some numbers at Scarborough, amongst moss at the roots of Gon- 



vallaria hifoUa , in May and June. 



It is very closely allied to A. pulicarius, but may at once be sepa- 

 rated from that species by the absence of the black spots on the tibiae. 



It should stand as the first species in the genus in our Volume.
