Very like the two species already described, and often confounded with 

 them. Head black ; cheeks and temples somewhat deeply punctate, but 

 the former are smooth apically ; frontal orbits only of ? , c^ with palpi, 

 angles of clypeus, facial and marks at vertical orbits, white. Antennae 

 compresso-dilated, attenuate and white-banded in both sexes. Thorax of $ 

 entirely black, scutellum white ; of c^ with pronotum, and rarely callosities 

 at radix, white ; areola broadly semilunar. Scutellum punctate, with erect 

 pale pubescence, that of <? rarely black. Abdomen sub-parallel-sided ; 

 with distinct ventral fold ; cyanescent or purpurascent ; first segment nearly 

 always immaculate ; second to third or fourth always with lateral trans- 

 verse white marks ; post-petiole finely aciculate, apical angles rounded ; 

 gastrocaeli large and deep, with the intervening space closely striate. Legs 

 black ; anterior tibiae in part pale flavous ; hind coxae finely punctate, of 

 $ with scopulae smaller than in the last described species. Wings some- 

 what clouded ; tegulae often white ; stigma piceous ; areolet sub-deltoid. 

 Length, 12-16 mm. 



If the first segment be immaculate, the insect may with confidence be 

 referred to the present species, which is usually smaller than siigi/hiiorius, 

 with which it was for long intermingled. The abdomen, especially towards 

 the apex, is more brightly cyaneous, its first segment nearly always immacu- 

 late, which, with the smooth apex of the cheeks and smaller coxal tufts of 

 the $ , render it sufficiently distinct. 



Bignell once bred it in South Devon, on June 17th, from pupae of 

 Odontopera bidentata ; and I have seen a $ taken by Mr. R. C. Bradley, 

 at Llanbedr, in Carnarvon, on August 22nd, 1895 ; and others by Col. 

 Yerbury and him at Barmouth, in August and June. It is not uncommon 

 on the Continent, but does not appear to have been there bred.

The present and followmg species are distinguished from their congeners 

 at once by the broad, clear white band on the hind tibiae in both sexes. 

 Head black ; cheeks and temples somewhat inflated and sparingly 

 punctate ; orbits more or less white ; $ with palpi, a mark in centre of each 

 mandible, clypeus laterally and often the whole face, white. Antennae 

 setaceous, conspicuously dilated, first joint of flagellum twice longer than 

 broad, the seventh quadrate ; white-banded in $ only, scape white beneath 

 inc?. Markings at radix, and the apex of the somewhat flat scutellum, 

 white ; upper metathoracic areae complete, areola sub-quadrate, not longer 

 than broad, posteriorly emarginate. Abdomen bluish, especially in $ , 

 towards the apex; post-petiole aciculate in $, aciculate-punctate with 

 strong carinae in S ; second segment rather longer than broad ; gastrocaeli 

 large and deep, the intervening space rugose. Legs black ; anterior femora
