suture and vanishing before the apex, the third interstice with 

 two impressions, near the outer margin behind is a testaceous 

 spot, more or less distinct and large, the apex being likewise 

 sometimes livid testaceous ; body beneath black, legs testaceous 

 red. Length 1^ line. 



Notaphus castanopterus, Steph., is a pale and immature variety 

 of this insect, from which Lopha Spensii and Doris of the Ste- 

 phensian cabinet do not differ. 



It is an abundant species in marshy places and is widely dis- 

 tributed : Whittlesea Mere and the fens of Cambridgeshire, 

 Huntingdonshire and Lincolnshire, in profusion ; and in the 

 London district. It is included likewise among the Irish Bem- 

 bidia.

 longo-ovatis, fortiter punctato-striatis, macula obsoleta 

 ante apicem antennarum basi pedibusque runs. (PI. III.

Above pitchy black, occasionally obscure greenish brass. Head 

 with a deep slightly flexuous furrow on each side, somewhat 

 approximating in front, enclosing a strongly elevated ridge on 

 the crown ; mandibles pitchy red, palpi and antennae pitchy 

 black, basal joint of the latter wholly and base of some of the 

 following joints red. Thorax subquadrate, sides dilated and 

 rounded before the middle, rather narrowed behind, but the 

 base still wider than in the preceding species, posterior angles 

 right angles or slightly prominent, disk convex, the dorsal furrow 

 met in front by a semicircular impression, and behind also by a 

 slightly rugose depression, the base with a large bistriated fovea 

 on each side. Elytra oblong-ovate, rather broad, convex, deeply 

 punctate-striated, the punctured striae abbreviated before the 

 apex which is smooth, the striae nearest the suture very deep, 

 the exterior ones much more slender, the third interstice with 

 two impressions, near the outer margin behind is a more or less 

 obsolete round red spot; underside black, legs entirely red. 

 Length If line. 



In its general structure and in the deep striae and punctuation 

 of the elytra, this species is allied both to assimile and gilvipes, 

 but it is a more robust insect, the thorax especially is larger and
