 bard a Say. It is subject to attack by egg parasites, two species, T e 1 e- 

 nomus podisi Ashm. and T rissole us podisi Ashm., having been 

 reared from its eggs, which have been described by Dr Riley as " bronze- 

 colored caldron-shaped objects, with a convex lid, around which radiate 15 

 or 16 white spines." They are placed side by side in small clusters on 

 leaves or other objects. The young bugs, according to Riley, are ovoid, 

 shiny black, with -some bright crimson about the abdomen, and when fuii 

 grown four yellow spots appear on the thorax and the abdomen is more 

 yellowish. This author also states that the diet of the young is principally 

 vegetarian, though a young b-ug has been observed to destroy a grub of the 

 Colorado potato beetle four or five times its own size. This species has 

 been taken by Mr Bueno, in June, July, September and October, in various 

 localities about New York city, and has been recorded by Dr Smith, from 

 Staten Island. Its distribution has been given by Kirkland, in addition to 

 the above localities, as follows : Canada, Massachusetts, Pennsylvania, 

 Maryland, Virginia, Wisconsin, Illinois, Nebraska, Kansas, Iowa, Missouri 

 Colorado, Indian Territory, Texas and California. He states that it is said 

 to occur generally throughout the south and west, and that It is rare in 

 Massachusetts. Professor Osborn records this species from Williams 

 Ariz,
