f. major, Black. This species is very closely allied to D. Bou- 
cardi, Crotch; but I believe it to be a distinct species. I do not 
find any difference in the sexual characters. I have before me 
an example of &. Boucardi (female) which differs from &. major 
of the same sex as follows:—The general form is much more 
ashy-coloured instead of being clear bright fulvous, the general 
form is much more convex, and not so wide, the elytra are more 
nitid, and evidently less closely punctured, and the elevated 
middle space of the prosternum is differently shaped, being 
dilated immediately behind its front margin, and theu distinctly 
narrowed again hindward, while the same piece in A. major is 
uniformly narrowed from the coxze to the front margin.

Very distinct by the sharply defined and conspicuous black 
markings on the elytra, which consist of a number of longitu- 
dinal lines forming (in the example before me) a strong vitta on 
either side the scutellum reaching nearly the middle of the ely- 
tra and dilated at its base, and several other vitte which are 
dilated and run into each other here and there in such fashion 
as to form anirregular and very strongly zigzagged fascia near the 
apex not touching the lateral margin, and on each elytron a discal 
fragment of a fascia reaching neither the suture nor the lateral 
margin, and connected at its external side with the hinder 
fascia.
