Again he danced sidewise before her, strutting and showing off like a 

 peacock, whirling around and around. Professor Peckham at first supposed 

 that this turning around was accidental, but it hap- 

 pened so regularly at a certain stage of 

 courtship, that he concluded that it was an 

 important part of his display, serving the 

 better to show his brilliant abdomen. 1 

 In approaching the female the males of Philseus 

 militaris were very eager and fairly quiv- 

 ered with excitement. The first two legs 

 were raised over the head and curved toward 

 each other, so that the tips nearly met, and the palps 

 were moved up and down. (Fig. 28.) 2 



Astia vittata is peculiar in the fact that it has two well marked male 

 forms, which .shade into each other, but maintain at least one characteristic 



distinction, namely, three tufts of hair which mark 

 the black form, niger. Mrs. Peckham was kind

 courtship dances. This was prior to the 

 receipt of the work from which I have been quot-

succeeded, however, in resuscitating both males by 

 doses of water and good nursing. One of them 

 in a short time seemed quite well. 



I placed the three together in a box, and had 

 the privilege of observing, in some degree, what 

 the Peckhams have so fully described. The most 

 lively male at once began animated movements, 

 which were evidently induced by the presence of 

 the female, who, however, ran away and kept cir-

 any disposition to respond to the advances made. 

 The male threw himself into what may be described as a rampant position 



in the act of vaulting during a 

 love dance. (From Nature.)
