70 ENTOMOLOGICAL SOCIETY 
noticed as yet is Dilophogaster, in which the male antennae are 
nine-jointed and the female ten-jointed. Following the funicle 
proper comes the club. This is normally three-jointed, but the 
joints often coalesce, so that they cannot be distinguished. It may 
be conical {Leucaspis} or obconical ( Cercobelus) ; it may be 
squarely truncate at tip ( Sphegigaster) , or obliquely truncate 
(Copidosoma), or it may be laterally flattened (many genera). 
The second joint may have a tooth-like projection (JVotanisus} , 
or the tip may be prolonged into a filamentary process ( Chryso- 
charis) . It may equal in length the whole funicle, or it may be 
shorter than the last funicle joint. At the tip of the scape the 
antenna is always abruptly elbowed, and this was formerly con- 
sidered one of the most important of the family characters ; but, 
as we have already indicated, it is sometimes found with the 
Proctotrupidas, notably in the sub-family Scelionince. 
The Thorax. 
The prothorax. This segment is composed almost entirely of 
notum, which extends ventrally below the latero-ventral angle, and 
is nearly continuous ventrally, with the sub-family Chalcidince 
in particular. It is usually quite short, although assuming con- 
siderable size in the Eurytomince, Aximince, and Torymince. 
Occasionally, when seen from above, it appears conical (Eu- 
lopkincz], again transverse quadrate (Chalcidince}. The pro- 
sternum is usually narrow and transverse, but is occasionally tri- 
angular, with its apex directed anteriorly. The proepisterna are 
usually narrow and situated in an oblique cephalo- ventral plane. 
In Smicra they are one-half as broad as long. 
The mesot/iorax.-^With the Chalcididae the scutum, scutel- 
lum and postscutellum of the mesonotum are distinguishable. 
The so-called postscutellum of Forster is, however, believed by 
Thomson to belong to the metanotum, and would hence be meta- 
prcescutum. The diversity in certain points of the mesonotum 
has afforded good classificatory characters. The mesoscutum may 
be either entire or its lateral portions may be separated from the 
dorsum by deep sutures, forming the so-called parapsidce (Mac- 
L,eay),ptag-<zscap2itares(Ha\iday), or scapulce (Thomson). These 
sutures, known ordinarily as parapsidal sutures, usually approach 
posteriorly and sometimes almost meet at the scuto-scuteilar su-
