to the same, a little before middle, a broader fascia behind middle, and 
a third before apex (not reaching sides), purplish-blue ; upper surface 
depressed, distinctly but not strongly punctured, with a plain inter- 
mixture of smaller punctures; legs metallic, bluish or greenish, very 
hairy. L. 10-16 mm. 
On flowers, Umbellifere, &c.; doubtfully indigenous ; Manchester; Dorking, 
one specimen taken in June (Waterhouse); there is a specimen in Dr. Power's col- 
lection, without locality, taken by Mr. Buxton; these specimens are probably 
importations, as they might easily be imported in the larval state in foreign bee- 
hives. 
(%. apiarius, L. Very like the preceding, but it may easily be 
distinguished by having two fascie on the elytra and the apex purplish- 
blue, whereas in J. alvearius there are three cyaneous fascie and the 
apex is orange-red; the head and thorax are more finely punctured, and 
the elytra are a little more shiny and less pubescent. L. 10-16 mm. 
On flowers; Coombe Wood, near Dover; Norfolk; Manchester; New Forest; if 
these specimens are authentic, the same remarks probably apply to them as to the 
preceding ; the insects were not considered indigenous by the old authors Marsham 
_and Samouelle. 
CORYNETINA. 
This tribe contains a few genera, of which the most important are 
Necrobia and Corynetes ; they are small, brightly coloured insects with 
strongly clavate antenne, and with the apical joint of all the palpi 
not or comparatively slightly enlarged; in both the perfect and the 
larval state they are found in earcases, old bones, skins and other 
animal matter, on which they feed; the larve do not appear to differ 
materially in structure from those of the preceding tribes ; four genera 
occur in Europe, of which two are found in Britain. 
I. Club of antennz compact, with the penultimate joints 
strongly transverse ; eyes glabrous Et ah ton Tons 
II. Club of antennz loose, with the penultimate joints not, 
or hardly, transverse; eyeshairy. . . . . . . . - Corynetes, Herbst. 
Necrosis, Lafr. 
NECROBIA, Laitreille. 
About a dozen species are contained in this genus, three of which are 
found in Europe, and the remainder oeeur in Africa, India, Ceylon, 
the Australian region, &c.; through their compact round club they 
afford the strongest approach to the Clavicornia. No notice of this 
genus is complete without a reference to the fact that one of the species, 
NV. ruficollis, saved the life of the celebrated Latreille : when imprisoned 
at Bordeaux during the French Revolution, he found a specimen of the 
insect on the walls of his cell, and sent it to M. Bory de St. Vincent, 
whom he knew to be interested in Entomology, and who had influence 
enough to secure his release; as he himself says, ‘“‘ Renfermé dans un
