seeds of Ficus Sycomorus and Carica. 53 



made by the camera and reduced to a scale. The fore 

 legs are represented m fig. 19, the middle ones in fig. 20, 

 and the hind ones in fig. 21. 



The coxae in all these legs are very large, flattened, 

 and oval in form, the trochanters very small, the femora 

 large, flattened, and ovate ; the tibiae are about the 

 length of the femora, armed beyond the middle and at 

 the extremity with a number of short strong spines ; the 

 tarsi are five-jointed, the four basal joints very short, 

 the fifth longer, subclavate, and the ungues are strong, 

 the base of each on the inner edge being dilated and 

 flattened. A minute pulvillus exists between the ungues, 

 but is concealed by the dilated bases of the latter. The 

 abdomen is elongated, flattened, very movable, the 

 joints having the posterior margin produced on each 

 side into an acute point, allowing much lateral motion 

 in this part of the body. It is composed of seven joints, 

 the first of which is small in consequence of the dilata- 

 tion of the posterior coxse. The terminal segment has 

 the middle of its hind margin rounded, slightly pro- 

 duced backwards and entire (figs. 8 and 15), and is armed 

 with two elongated villose cerci destitute of articulations, 

 each terminating in an acute point. The base of each of 

 these cerci is internally in communication with a gigantic 

 trachea, which, in transparently mounted specimens, 

 may be traced backwards as far as the prothorax. The 

 male organs of generation are generally retracted within 

 the extremity of the abdomen, as shown in figs. 1, 8, and 

 15, in which they are represented as seen in trans- 

 parently mounted individuals ; in figs. 16 and 17 these 

 organs are exserted, and are seen to consist of a very 

 slender tube, which is armed with two very minute 

 genital claspers or oblong flattened appendages, having 

 three or four exceedingly small curved teeth at their 

 extremity; (fig. 18 represents the extremity of one of 

 these claspers with three of its little teeth). 



Description of the female. — The female Sycophaga is 

 represented in fig. 2, drawn by camera from a living 

 specimen sitting quietly on the under side of the glass 

 cover of the little box in which it was placed. Its various 

 parts are therefore represented in their proper relative 

 proportions, which is desirable to be borne in mind 

 whilst comparing this figure with the original repre- 

 sentation of the upper side of the female in Trans. Ent.
