Determined as Coreus ordinatus by Mr. Say. 



This is the ordinary squash bug, so well known to farmers and 

 gardeners. It is now found over the whole length and breadth of the 

 United States, extending into Mexico, the West India Islands, Cen- 

 tral America and Brazil. In California and Arizona it sustains the

 the most persistent pest of the melon and squash grower, swarming 

 both upon the fruit and the vines, sucking their juices, and causing 

 them to shrivel and die.

 Mr. Say was induced to redescribe this species because of the un- 

 certainty produced by the Fabrician description, which reads — "An- 

 tenna? . . . articulo sec undo scabro, tertio apice dilatato, membrana- 

 ceo, atro, ultimo claviformi." The manner in which the antennae are 

 attached to the front of the head causes the lateral produced lobes to 

 appear like basal joints. Hence, Fabricius describes the second 

 joint to be scabrous, instead of the basal one. The apical, or ulti 

 mate, joint would appear distinctly club-shaped but for the dilata-
