strongly widened towards apex. J . Posterior femora furnished at apex with 

 a small ]>lunt tooth ; posterior tibise very feebly ])isinnate, rather strongly 

 curved inwards at apex. Length, 2'3 — 3 mm. 



In A. dubia the thorax is distinctly narrowed before the base ; 

 the scntelhini is much smaller than in A davidiana, and the first stria 

 reaches the base of the elytra at some distance from the scntellum. 

 The third stria is sometimes very slightly sinuate. In the shape of 

 the thorax A. davidiana resembles A. scita and A. ovalis. A. scita has 

 longer antenna?, a smaller scutellum, much less closely punctured striae, 

 and the 3rd-5th strioe strongly sinuate. A. ovalis is rather more 

 elongate, and has much longer antennse, the third stria of the elytra 

 straight, and the interstices more finely punctured. It, however, agrees 

 with A. davidiana in having a large scutellum, and the first stria 

 ending at its side. 



A. davidiana is probably fairly generally distributed in England. 

 I have seen it from Southport, Deal, and near Llancillo. It is curioxis 

 that such a very distinct species should have so long been confoiuided 

 with A. dubia. Some species of Coleoptera get a reputation for being 

 " very variable," and so no one seriously tries to separate the various 

 forms, several of which may be perfectly good species. It may be 

 that A. davidiana is identical with the var. bicolor, Scliaum, of 

 A. dnbia, but it is impossible from the description of this form to 

 decide if this is the case.

Antennae white, with distinct black annulations. Palpi white, with two 

 black rings on the terminal joint, one at the base the other before the apex. 

 Head and Thorax white, the latter sprinkli>d with black scales. Forewings 

 white, sprinkled with black scales which are assembled in a redujjlicated sjjot 

 close to the base, a spot on the fold a little beyond it, a costal spot at one- 

 fourth attenuated downward to the fold, an indistinct shade-band across the 

 middle, not reaching the dorsum, and beyond this a profuse sprinkling along 

 the costa and around the apex and termen, also through the hoary white cilia ;
