132 Rev. T. A. MarshaH's monograph of 



this species ; it has 18- (i. e., 17-) jointed antennfe, and 

 the abdomen grooved beneath at the apex to receive the 

 point of the terebra. The latter character means very 

 little, and may be seen in many females accidentally. 

 Wesmael, however, states that its absence is the only 

 reason why he did not join the two species. A greater 

 difficulty seems to arise from the silence of Nees respecting 

 the dense pubescence of the face, which distinguishes 

 canesccns from all other species. Thomson doubtfully 

 assigns rctusus, Nees, to his own caudatus. 



Described from one male and three females. A pair 

 is in Cameron's collection, from Clober, Scotland ; Fitch 

 possesses a ? , and another was taken by me in Bradgate 

 Park, Leicestershire.
