mibartir circumflexus, F. Tankin Nursery. Coll. W. Dallimore. 
One of the larger species, occasional in standing water throughout. . 
the London district but not common and restricted in range to the 
south of England. 
A larva of another and commoner species of the genus, D. marg?- 
nalis, Li, has been taken in one of the outside Lily tanks. Coll. 
C. P. Rafiill. 
The presence of both these species in such circumscribed waters 
is explamed by the fact that the perfect insects fly readily and 
frequen and often alight and deposit ova in quite superficial 
pew 
SERRICORNIA. 
Ptilinus pectinicornis, 2. Arboretum. Coll. W. Dallimore. A 
not uncommon species where larvae bore into palings, gate Las 
&c., and very frequently into:the dead timber of standing bee 
haskiisdarii serricorne, F. In small white beans in propoeating 
pits. Coll. H. Green. Like several species which have been taken 
here, this is a cosmopolitan ‘sect whose larvae, feeding as they do on 
various seeds and roots (ginger, tS &c.), are carried about the 
world by commerce. There is no reason to doubt that the species 
was thus imported with seeds of some ind to Kew, and although 
normally a ‘ British beetle’ has no real claim to a place i in the 
British fauna, 
CLAVICORNIAs 
Necrophorus vespillo, 1. Bulb pit. Coll. R. Joyce. One of the 
‘burying beetles’ which deposit their ova in dead animals, and 
whose larvae feed on carrion; generally distributed in Britain. 
HETEROMERA. 
Helops striatus, Foure. Propagating pits. Coll. H. E. Dow 
on British species, often found under bark, hpectally 
of dead fir trees and usually in dry and sandy localities. 
RHYNCOPHORA. 
Scolytus destructor, Ol. Arboretum. Coll. W. Dallimore. One 
of the wood-boring weevils, common and very injurious to elm. 
(Exotic species.) 
_ Exechesops jordani,,W. E. Sharp. Coll. H. Green. This very 
distinct and interesting species was discovered among seeds of a 
Lily imported from Tangany ika, Africa. Previous to its deserip- 
tion the genus Exechesops scnadinale but five eee only, one of 
which (4. monstrosus, Pasc.) was a native of Afric he present 
species is much larg er than any of the others, wey its exceedingly 
prominent eyes give os insect a remarkable aspect. 
The nearest British ally to Exechesops is perhaps Macrocephalus 
albinus, L. A very rare species found socasionally in decaying
