Lagria.| HETEROMERA. 27 
Female broader, with the last joint of the antenne twice as long as 
the preceding, and the eyes smaller, not or scarcely projecting beyond 
sides of thorax. 
In hedges ; on flowers, &c. ; by beating and sweeping ; rather local, but sometimes 
in profusion, generally distributed throughout the London and Southern districts, and 
not uncommon in the Midlands; rarer further north ; Scotland very local, hitherto 
found only in the Moray district, but it probably occurs in several others ; Ireland, 
Queenstown, Killarney, Waterford, Portmarnock, &c. 
CISTELIDA (Alleculide). 
This family, which has been by some authors included under the 
Tenebrionids, contains several genera, of which Allecula, Cistela, and 
Omophlus are the most important, but it is not of large extent; the 
species are widely distributed, but appear to be mostly attached to tem- 
perate and moderately warm climates ; eight genera occur in Europe, 
containing about one hundred species, of which five genera, represented 
however by only seven species, are found in Britain; they differ from 
the Tenebrionids and Lagriide in having the tarsal claws pectinate, and 
from all the following families in the fact that the anterior coxal cavities 
are closed behind; the antenne are usually long, filiform or more or less 
serrate, and are inserted behind the base of the mandibles; the maxil- 
lary palpi are 4-jointed, rather long and often much dilated at apex ; 
the eyes are kidney-shaped ; the cox are somewhat variable, but the 
posterior pair are usually contiguous, and the anterior pair subglobose ; 
the epimera of the mesosternum reach the coxe ; the legs are usually 
long, the tibia being more slender than the femora and furnished with 
distinct spurs; the posterior tarsi have the first joint elongate, and the 
penultimate often bilobed. 
Our British genera may be distinguished as follows :—- 
I. Abdomen composed of five ventral segments ; mandibles 
emarginate; antenne inserted just behind base of man- 
dibles. 
i. Penultimate joint of tarsi not furnished with a mem- 
branous plate beneath. 
1. Anterior tarsi considerably shorter than the tibia ; 
antennz comparatively short and stout . ee 
2. Anterior tarsi as long or nearly as long as the tibiz ; 
antenne long andslender. . . . . . + . + « CISTELA, F.
