seeds of Ficus Si/comorua and Caricd. 57 



In figs. 40, 45, and 47 the maxillas (which are repre- 

 sented as detached, and seen in two different positions in 

 figs. 48 and 49), are seen to protect the middle part of 

 the lower mouth organ or labium, which arises from an 

 elongated slender mentum, and is apparently articulated 

 in its middle ; the organs extend backwards almost to 

 the base of the head (fig. 40), and are protected by two 

 auxiliary corresponding pieces, which ordinarily stand 

 upright (vertically), but which are seen in the figure 

 lying flat, the one on the left side being partially hidden 

 by the serrated appendage of the mandible on that side 

 of the head ; these are also seen in fig. 45 extending as 

 far back as the base of the head. I have never met 

 with any similar pieces in any other insect, and cannot 

 conjecture what may be their analogous structure 

 or use, except as defences of the delicate lower parts of 

 the mouth. Fig. 41 represents the upper side of the 

 head of the female, with the antennae and mandibles 

 removed, showing the central deflexed point of the 

 clypeus, the ocelli, and the two black hastate spine-like 

 spots near the insertion of the antennae. Fig. 43 shows 

 part of the front of the head of the female, with the 

 mandibles and antennae removed, exhibiting the notched 

 sockets on each side for the insertion of the base of the 

 mandibles. Fig. 44 shows the deflexed anterior margin 

 of the clypeus. 



The antennae in this sex (fig. 51) are of moderate 

 length, the basal joint being robust and somewhat 

 conical ; the second joint of moderate size, much 

 narrowed at the base ; the third joint very small, as is 

 also the fourth, but this latter is furnished with a 

 subulated lobe on its outer edge ; the eight remaining 

 joints are distinct, and nearly of equal size and thick- 

 ness, the three terminal ones not being soldered into a 

 mass, as in many Chalcidida. 



The fore wings are of large size, with the cubitus 

 rather obliquely deflexed into the disc of the wing (fig. 52). 

 The legs are unequal in size and form ; the fore legs are 

 robust (fig. 54), with a strong femur, very short thickened 

 tibia, and long five-jointed tarsus, with strong curved 

 ungues, and a large pulvillus ; the middle legs (fig. 55) 

 are of the ordinary form, the femora slightly thickened 

 in the middle, the tibiae long and slender, and the tarsus 

 as long as the tibia, with a still larger pulvillus ; the 

 hind legs (fig. 56) have the femur short and much dilated
