THE YOUNG 



yellow; striae punctured to beyond the 

 middle. 



B. quadHpustulatum, — Length, if lines. 

 Antennae entirely dark ; legs with the 

 ! femora black. 



The latter of these species is very scarce. 

 : The former two are common, especially in 

 clayey cliffs, where they inhabit the cracks 

 | of the clay. 



4. Elytra yellow, with darker bands. 



B articulatum. — Lenth, i£ lines. Head 

 and thorax green ; elytra with two brown 

 bands behind the middle. 



B.pallidipenne. — Length, 2\ lines. Head 

 and thorax green ; elytra with one dark, 

 toothed band at middle, and a dark patch 

 at the scutellum. 



B fumigatum — Length, if lines. Head 

 and thorax dull bronze ; elytra with three 

 dark, irregular bands. 



B. articulatum is tolerably common ; B. 

 fumigatum more local ; and B pallidipenne 

 is very local, occurring only, I believe, on 

 sandy sea-shores. 



5. Elytra bronze. 



B. bipunetatum — Length, 2 lines. Eyes 

 very prominent ; elytra with two deep 

 depressions on each. 



B. lampros — Length, i\ lines. Antennae 

 black, with two basal joints more or less 

 red. 



B nigricorne. — Size of lampros. Antennae 

 entirely black ; thorax wider at base than 

 that species. 



B. lampros is very common everywhere ; 

 B. bipunetatum is somewhat local ; and B. 

 nigricome occurs, I believe, only sparingly 

 in heathy places. 



A variety of lampros (velox) is not un- 

 common, with a larger thorax and with 

 seven striae {lampros has only six) on each 

 elytron. 



6. Elytra entirely green or blue- green. 

 Legs entirely yellow. 



B decorum. — Length, 2} lines. Upper 



NATURALIST. 43 



side green ; eyes prominent ; elytra parallel- 

 sided. 



B. monticola. — Length, 2\ lines. Upper 

 side green; eyes prominent ; elytra rounded 

 at the sides. 



B. Stephensi. — Length, 2f lines. Upper 

 side green ; elytra with a red blotch before 

 the apex. 



Legs yellow, with the femora rather 

 pitchy. 



B. brunnipes. — Thorax short ; upper side 

 green. 



Legs brown yellow or pitchy. 



B. tibiale. — Length, 2^ lines. 



B. atroc&ruleum. — Length, 2 lines. 



Both these species are dark blue-green 

 above ; in the former the thorax is not 

 much narrowed behind and the elytra are 

 ovate ; in the latter the thorax is narrowed 

 behind and the elytra are elongate. Atro- 

 caruleum is also a darker insect. 



The commonest of these somewhat diffi- 

 cult insects is undoubtedly brunnipes, which 

 seems to occur plentifully everywhere ; 

 monticola, tibiale, and atrocceruleum are 

 tolerably common among shingle in river 

 beds; decorum and stephensi are more 

 local. 



There is another green insect of this 

 genus, stomoides, which differs from all the 

 others in having the antennae entirely 

 yellow-red, the legs also being yellow. This 

 species is not so common as some of the 

 others, and is separated on account of a 

 difference in the length of the eighth stria, 

 which is not entire in this insect, but want- 

 ing towards the base. Length, 2\ lines. 



7. Elytra green, with yellow markings, 

 B. lunatum, the largest species of the 

 genus, measuring about 3 lines in length, is 

 dark green on the upper side, with a curved 

 crescent-shaped mark before the apex of 

 each elytron. 



B. testaceiim. — Elytra green, with very 

 large yellow spots, so that only the suture
