DORATURA STYLATA. 19 



Norfolk ; with times of appearance, July and August. 

 Sahlberg states, however, its occurrence over the 

 greater part of Europe, and, from the number of 

 varieties he notes, it probably is not uncommon in 

 Scandinavia. 



Size, 0-22 to 0*27 inch, or 5*5 inch to 6*0 milH- 

 metres.

Brachelytrous female. Silver-grey. Head obtusely 

 or almost roundly produced. Carina not visible. 

 Three black spots on the vertical apex, the middle spot 

 the largest. Vertex shorter than the pronotum. Eyes 

 prominent. Pronotum and scutellum yellow, with 

 whitish or greyish streaks and spots. Abdomen large 

 and tapering to a bluntish point, ending with two long 

 genital valves, from which the saw-case much pro- 

 trudes. The pygofer is about three times longer than 

 the genital plate above it. This style-like organ fur- 

 nishes the specific name of the insect. Erons broad 

 between the eyes, with a dark wave-like streak con- 

 necting the same, and two spots below. Rostrum very 

 short. Clypeus small and ovate. Antennae fixed 

 within deep fossae. Each segment on the under-side 

 of the abdomen is ornamented with a crescentic spot. 

 Legs yellow, with pale ciliations. Some specimens 

 show a dark inner stripe on the hind tibise. 



Brachelytrous male is much of the same colour as 

 the female, but brighter. The vertex is redder, and 

 the elytra are iridescent, as if burnished with gold.
