114 INSECTA, 
have entitled them to the common appellation of Golden Wasps, or 
Guépes dorées. They are seen walking about in a continued state of 
agitation, and with hasty motions, on walls and fences exposed to 
the Lurning ardour of the sun. They are also found on flowers. 
Their body is elongated and covered with a firm tegument. Their 
antenne are filiform, geniculate, vibratile, and composed of thirteen 
joints in both sexes. The mandibles are narrow, arcuated, and 
pointed. The maxillary palpi are filiform, usually longer than those 
of the labium, and composed of five unequal joints; the latter consist 
of three. The ligula is most frequently emarginated. The thorax 
is semi-cylindrical, and presents several sutures or impressed and 
transverse lines. The abdomen of the greater number forms a 
semi-ova! truncated at base, and at the first glance seems suspended 
to the thorax by its whole width; the last ring is frequently marked 
by large punctures and terminates by dentations. 
The Chrysides deposit their ova in the nests of the solitary Mason 
Bees, or in those of other Hymenoptera. Their larve devour those 
of the latter. 
In some the maxille and labium are very long, forming a false 
proboscis that is bent underneath, and the very small palpi are bi- 
articulated.

The others are destitute of this false proboscis; their maxillary 
palpi are moderate or elongated and composed of five joints; those 
of the labium have three. 
Sometimes the thorax is not narrowed anteriorly; the abdomen is 
semi-oval, concave, and presents externally but three segments, as 
in Chrysis proper or. 
Curysis, Fab. 
Those, in which the four palpi are equal, and where the ligula is 
profoundly emarginate, form the genus
