t)ELTOCEPHALUS PlCTURATUS. 69 



edgings. Legs pale, sparsely spotted with brown. 

 Some specimens show the pronotum furnished with 

 seven or more ferruginous vertical dashes. 



My figures are from insects in Mr. Edwards' col- 

 lection. He notes it " scarce," but that he has taken 

 the insect singly in three localities in Norfolk. 



Size, 0*13 inch, or 3*50 millimetres.

This insect appears greatly to resemble that last 

 described, but the vertex appears to have the sides less 

 arcuate, and there is a difference in the form of the 

 rusty red spots thereon. The pronotum also is spot- 

 less. The elytra are marked much as in B. repletus. 

 Legs perhaps are rather darker in the tint, and the 

 black inner streak on the hind tibia is more decided 

 than in D. repletus. 



" Scarce. Pitlochry, Perthshire. Dunston Common, 

 near Norwich." From Mr. Edwards' cabinet. 



Size, 0-13 inch, or 3*50 millimetres. 



Mr. J. Scott has placed D. picturatus amongst the 

 synonyms of D. Flori, Fieb., but he gives no special 

 reasons for so doing. Dr. Paul Low, however, remarks 

 that these insects are clearly distinct. He admits that 

 the colouring is very similar in both kinds, but that 

 there are differences in the genitalia of the two males. 

 The form of the side plates (seitenlajjpen) of D. Flori is 

 not that of D. picturatus, and he remarks that the 

 figured details given by Fieber are true to Nature. 



He also describes their differences of habitat. D.
