26 Mr. James Edwards’ Synopsis of 
g. Crown with a wide central stripe, a transverse marking 
before the apex, and one or more curved bands proceeding from 
the middle keel to the side margin, and widening outwardly, dark 
brown or black. Of these markings the transverse one before the 
apex is the most constant. 
@. Paler, the irroration on the elytra almost or eutirely 
wanting, and the markings on the crown reduced to a central 
stripe, and a few spots on the margin round the apex. Length, 
53—74¢ mm. 
At the roots of low plants ; not very common. 
This species is usually divided into three, namely :— 
1, cuspidata, Fab., having the crown broader than 
long, its sides strongly rounded, and the apex somewhat 
cuspidate (in the female with the sides nearly straight). 
2, depressa, Fab., having the crown longer than broad, 
with its sides strongly sinuate. 
3, producta, Germ., a form intermediate between the 
two preceding, having the crown somewhat equilaterally 
triangular, its sides straight or very faintly concave near 
the ocelli. 
All these forms may sometimes be taken in company. 
The characters laid down by authors derived from the 
genitalia are simply differences of degree.
