4. ANDREKA. 31 



Var. /3. The margins only of the first and second segments narrowly 

 red. 



Dr. Nylander has compared specimens of this species with the 

 type in the Museum at Kiel ; the name given by Fabricius is there- 

 fore adopted. The species appears usually about the beginning of 

 June : it frequents by preference the wild briony ; it has been 

 taken frequently near Highgate ; it is also found at Weybridge, and 

 near Blackwater, Hants, at Bideford and Ilfracombe, JNorth Devon. 

 The male resembles that of A. rosce, but may be known from it 

 by having the joints of the antennae simple ; in A. rosce they are 

 arcuate.
