side at base, and the posterior angles not acute; the chief character, 
however, lies in the anal spine, which is short and blunt and more or 
less truncate at apex; the posterior tibie, moreover, are marked with 
four oblique strigosities instead of with three only as in M. pumila. L. 
3-4 mm. 
On flowers, &c.; especially in chalky districts ; very local, but occasionally common 
where found; Mickleham, Reigate, Caterham, Maidstone, Chatham ; Folkestone ; 
Eastbourne ; it appears to be confined to the London and South-eastern counties. 
M. parvula, Gyll.; v. inequalis, Muls. Smaller than the two pre- 
ceding, which it resembles in colour and general appearance ; it is easily 
distinguished from both by its plainer and coarser pubescence and the 
very slight sinuation at each side of base of thorax, the space between 
the sinuations being much broader and shorter; in the type form the 
posterior angles of the thorax are obtusely rounded, and the anal process 
is thick, conical and acuminate, about half as long again as the anus or 
hypopygidium ; the var. inequalis, however, appears to be the only 
variety of the species that occurs in Britain, and this has the anal process 
twice as long as the hypopygidium, and the posterior angles of the 
thorax scarcely rounded, the size also being a little larger; the posterior 
tibie are furnished with three strongly oblique strigosities, the first 
being very large and traversing almost the whole side of the tibia. L. 
25-3 mm. 
On Artemisia maritima, and probably on A. vulgaris; rarely on flowers; very 
local, but occasionally taken in numbers; Weybridge; Thames Ditton; Bushey ; 
Sheerness (in abundance, Champion and Walker); Deal; Folkestone; Sandown; 
Hants; Glanvilles Wootton. 
It is worthy of note that not a single species of the Mordellida, 
except those belonging to the genus Aznaspis, has been recorded from 
further north than the midland counties, and the majority are confined 
to the southern districts. 
ANASPINA. 
The species belonging to this tribe are small and delicate insects, 
without an anal style ; the body is rather fusiform than cuneiform or 
wedge-shaped as in the Mordellina ; the hind coxe are not very large; 
the posterior tibiz are armed with strong spurs ; the thorax has the sides 
not margined in front; the eyes are slightly emarginate and coarsely 
granulated, and the elytra have the epipleure, which in the preceding 
tribe are absent, narrow but evident; three genera, Pentaria, Cyrta- 
naspis, and Anaspis, are found in Europe, the latter of which is repre- 
sented in Britain by several species. 
ANASPIS, Geoffroy. 
About seventy species are comprised in this genus, of which thirty- 
nine or forty are found in Europe, and nearly all the remainder in North 
America and Northern Asia; the Australian region has furnished one 
species ; the characters given for the tribe will serve to distinguish the
