nigris. (Long, coi-p. 5 — 6 lin.)

maculata. Steph. Catal. 206. JVo. 2093. 



Black, clothed with a griseous pubescence^ most densely on the thorax : coleoptra 

 testaceous with eight black spots, ianr upon each elytron, placed two obliquely at 

 the base, the outer one largest, the next large, marginal, and about the middle, 

 and the fourth at the apex itself: the two basal spots are frequently united, 

 and sometimes the outer one is divided into two or three black streaks : legs 

 and antennte, black. 



Not uncommon on flowers in Colney-hatcli-wood in June, but 

 rather scarce in other parts within the metropolitan district. " Gib-

SECTION V. 



Tarsi tetraraerous, or trimerous : head not produced anteriorly into a rostrum : 

 antennw ^Vdoxvo., or slightly incrassated at the apex, sometimes moniliform ; 

 in the trimera clavate : articulations generally ] 1 : labium subquadrate, and 

 rather thickened : body oblong, with the thorax usually narrow, or subovate 

 or orbiculate: posterior femora frequently much incrassated. 



This section, which requires subdivisions as -hereunder, contains 

 the most splendid of the indigenous coleoptra : the larvse are chiefly 

 external feeders, and are considerably diversified: those of the 

 typical groups are, however, furnished with short legs ; the latter 

 are phytophagous, but those of the trimerous division are all, or

Black, slightly glossy, clothed with a griseous pubescence : antennae rather short: 

 elytra entirely rugose-punctate, livid, with an oblique black vitta at the 

 shoulder, and a spot of the same colour near the apex. 



Donovan mentions that he found a specimen of this insect in Drury's English 

 Cabinet, but as several of the insects in that collection have not been authenticated, 

 I have included them among the doubtful natives, until they be proved indi- 

 genous.
