TWO SPIDER HUNTERS. 57 



hatched. The larva developed rapidly retaining its hold at the 

 ^spot to which the mother had attached it. The spider remained 

 alive for six days, and the larva continued to grow for two days 

 longer when it died also, being at the time about two-thirds 

 .grown. We had great trouble in protecting our growing larvae 

 from the inroads of fungi and this was one of the many that 

 perished from that cause. 



The next example of fasciatus that came under our notice was 

 .a remarkable contrast to the one that we have just described, 

 being as slow and dignified as the other was nervous and hurried. 

 >She chose a place and kept to it, her steady labor being only 

 interrupted by occasional visits to the spider, but it took her 

 fifty minutes to complete the nest. When finished it was a 

 small gallery running down obliquely for an inch and a half 

 into the ground. 



The three spiders taken from fasciatus were all Attidae but 

 represented three different genera, Phidippus, Attus, and 

 Maewa. 



The one habit that this species can claim as peculiar to itself 

 is that of filling up the partly made nests that it is about to 

 abandon. We have never seen the sense of order carried to so 

 high a point in any other wasp. 



Our observations on fasciatus were made between July 

 thirtieth and August twenty-fifth.
