I. Thorax with the entire base finely margined ; form less 



convex A. OBLITERATA, L. 



II. Thorax with the base only margined near angles ; form 



more convex. 

 i. Claws short, scarcely visibly toothed ; form seuiiglobose ; 



colour yellow and black A. BOTHNICA, PayJc. 



ii. Claws long, distinctly toothed ; form slightly ovate ; 



colour red and black A. BIPTTNCTATA, L. 



A. obliterata, L. (M-nigrum, Gyll. ; livida, Muls.). Of a dirty 

 testaceous colour, with the thorax furnished with markings towards base, 

 which usually coalesce and form an M ; elytra lighter at sides, darker at 

 suture, and usually with two more or less defined dark bands at sides 

 which are often obsolete ; legs testaceous ; the elytra are occasionally 

 dark brown ; the upper surface is not very convex, and somewhat finely 

 punctured, and the thorax is very transverse and widest behind middle. 

 L. 3|-5 mm. 



Male with the fifth ventral segment of abdomen broadly emarginate 

 at apex. 



On fir-trees ; not uncommon and generally distributed throughout England and 

 probably Ireland ; Scotland, not common, Soiway, Tweed, Forth and Dee districts. 



V. fenestrata, Weise. This very distinct variety is quite black 

 with the apex of the elytra and a few more or less distinct spots at 

 margins, and on disc of the same yellowish or yellowish-red, and the 

 anterior angles of thorax somewhat broadly whitish. 



Two specimens were taken by the Rev. Hamlet Clark, on ling, at Northampton, and 

 I have found it in Sherwood Forest. 



A. bothnica, Payk. Almost circular, hemispherical, of an orange- 

 yellow colour with black markings, under-side black, legs yellow or dark 

 with tarsi lighter ; head black with a broad central spot yellow ; thorax 

 yellow with various markings ; elytra with suture black and other black 

 markings which differ in various specimens; punctuation fine. L. 

 3|-4 mm. 



V. crucifora, Weise. In this variety the margins of the elytra are 

 black and two large spots meet the suture at centre of disc, forming a 

 rough figure of a cross ; besides these there is a common spot at base of 

 suture, a spot on each elytron reaching base, two on each meeting sides, 

 and two free, one in middle and one towards apex. 



The variety only has occurred in Britain, Dr. Power having taken one specimen at 

 Moss Morran, Scotland. 



A. bipunctata, L. Oval, convex ; thorax black, with more or less 

 broad white borders at sides, or with anterior angles only white, or 

 entirely black, often with a double white spot in middle of base ; elytra 

 in the commonest form red, with one large round spot on each, but very 

 variably coloured, in some specimens the red colour prevailing, while
