SMYNTHURUS. 109 



teeth are four and five in number ; those of the male 

 and female are alike. 



The claws are simple ; the inner one is small ; there 

 are two tenent hairs on the upperside ; and the inner 

 claw, which is elongated, appears to terminate in a 

 small globular expansion, which has probably the same 

 function. The feet are alike in both sexes. 



Caudal appendage (PL LXIII, fig. 7). The basal 

 segment tapers slightly ; it bears scattered set?e, but 

 no tenent hairs. The terminal lamellae are elliptical, 

 without seta3 or teeth. At the end of the abdomen 

 are two setge much stronger than the rest. The 

 caudal appendage of the male resembles that of the 

 female. 



Some specimens have on each side two longitudinal 

 bands of rather darker yellow. These, I believe, only 

 form a variety. These specimens have three dark 

 spots on each side in the paler portion ; each of these 

 bears a hair. 



It is very amusing to see these little creatures 

 coquetting together. The male, which is much smaller 

 than the female, runs round her, and they butt one 

 another, standing face to face, and moving backwards 

 and forwards like two playful lambs. Then the female 

 pretends to run away and the male runs after her, 

 with a queer appearance of anger ; gets in front and 

 stands facing her again ; then she turns coyly round, 

 but he, quicker and more active, scuttles round too, 

 and seems to whip her with his antennae ; then for a 

 bit they stand face to face, play with their antennge, 

 and seem to be all in all to one another;
