Easily recognised by its ssinudgy black-lead appearance, caused by 

 the colour shining through the elytra from the black abdomen, and 

 the two more or less distinct patches on the elytra. 



Exceedingly common from June to October. 



Pale testaceous. Eh/tra longer than the abdomen, nerves white ; 

 in a line with the apex of the clavus a more or less distinct, broad, 

 w^hite, transverse band terminating at the claval suture ; disc, almost 

 in the middle with a black spot ; anterior margin above and below the 

 white band with a black patch, the lower one always largest. 



Head — crown testaceous, convex ; anterior margin with three black spots on each 

 side of the centre, one or other of them frequently united ; a little more in- 

 teriorly, two semi-circular black lines, and adjoining the posterior margin of 

 each eye two black spots ; frequently these characters are reddish- brown, and 

 more or less oblitei-ated. Face black, with or without a yellow central longi- 

 tudinal line ; on each side about four transverse yellow lines ; apical margin 

 yellow. Clt/peus yellow, broadly black down the middle. Cheeks brown ; 

 lorce yellow, margins black. AntenncB : 1st joint white, 2nd black ; setcB brown. 



Thorax — pronotiim somewhat greyish-testaceous, with two black spots on each, 

 placed trans vei'sely, and in a line with the posterior margin of the eyes. Scu- 

 tellum pale testaceous, with two small black punctures above the transverse 

 channel ; basal angles with a red or orange-red triangidar spot. 'Elytra longer 

 than the abdomen ; nerves white ; in a line witli the apex of the clavus a more 

 or less distinct, broad, white, transverse band, terminatuig at the claval suture ; 

 disc almost in the middle with a black spot ; anterior margin above and below 

 the white band witli a black patch, the lower one always largest and con- 

 spicuous ; apical areas fuscous. Legs yellowish ; thighs : 1st and 2nd pairs at 

 the base broadly black, beyond the middle a narrow black ring, and at the apex 

 generally a black spot ; 3rd yellowish, lower margin black ; inner side at the 

 apex with e black spot. TibicB yellowish ; 2nd pair at the base with a black 

 spot interiorly ; 3rd, down the inner margin black ; spines yellowish set in 

 black punctures. 

 Abdomen black; $ , beneath ; 3rd, -Itli, and 5th segments with a yellow triangle on 

 each side ; last segment yellow, posterior margin slightly concave. 



Length, li line.

Slightly larger, always clearer, and the characters on the elytra 

 more sharply defined than in D. puliearis, from which also it differs in 

 having a white band on the corium and the posterior margin of the 

 last abdominal segment of the ? of an entirely different shape. 

 Eieber has described a species {D.fasciatiis) which must be extremely 

 like the above, and it will be well to examine the markings on the 

 crown, and the shape of the posterior margin of the last segment of 

 the abdomen of females. 



Seemingly not uncommon, as I have met with specimens in nearly 

 all the collections I have examined.
