The above synonymy will show at a glance how very numerous 

 the varieties of this insect are, aud, singularly enough, they are nearly 

 all those of the female sex. To describe them at length I believe is 

 unnecessary, and I therefore only point out the principal variations. 



(J . ScufeJlum with a black triangular spot at each basal angle. 

 Elytra pale, almost transparent ; nerves black. 



Head : crown yellow, with or without a transverse black streak, termiuating in a 

 black spot at a little distance from each eye. Face yellow, immediately adjoining 

 the ocelli a black spot, below the latter a more or less large comma-shaped black 

 spot, frequently joined at the base, and forming a horseshoe-shaped patch. 



Thorax : pronotum yellow, transversely wrinkled ; disc more or less grey, and in the 

 interstices more or less sprinkled with minute black atoms ; anterior margin 

 behind each eye with a transverse, irregular-shaped black patch, behind which 

 is a small black spot. Scutellum yellow, with a black or dark brown triangular 

 spot at each basal angle, a dark brown central line slightly widened at the ti-ans- 

 versc channel, and a spot of the same colour on either side of the central line 

 above the channel ; or black, with a yellow triangle on each side next the apex. 

 l£lytra pale, almost transparent ; clavus pale gi-ecnish or yeUowish-white at the 

 base ; central nerve and apical two-thirds of the inner nerve black, the colour 

 slightly spreading on to the disc between their apices. Coriiim — nerves black ; 

 the areas on either side of the second transverse nerves narrowly piccous ; men".- 

 brane areas round the apex more or less broadly piceous or black. Leffs yellow ; 

 thighs generally with a black longitudinal streak on the inside ; tibicB with a 

 black longitudinal streak at the base exteriorly, and another at the apex in- 

 teriorly ; tarsi yellow, 3rd joints and claws generally black. 



Abdomen — above black, base yellow, posterior margin of the last segment entirely, 

 and of the penultimate on the sides, yellow ; beneath yellow, anterior margin of
