234 Forty-first Report on the State Museum. 



Dr. LeConte has expressed the opinion that the many relations 

 which we have of spider bites frequently proving fatal, have no doubt 

 arisen from the sting of these insects or others of the same genera. 

 Among the many United States species of Araneidce, he had never 

 seen one capable of inflicting the slightest wound. Ignorant persons 

 might easily mistake one of the ReduviidcB for a spider. A physician 

 had sent to him a fragment of a large ant, supposing it to be a spider 

 that came out of his grandchild's head. 



It would apjDear from the foregoing, that a certain degree of cau- 

 tion should always be exercised in the handling of any of the 

 Beduviidce, as the structural peculiarities which render them so for- 

 midable to many of the insect world, and so admirably adapted to 

 preying upon them, may readily be directed, under the slightest 

 provocation, to the serious annoyance and injury of man.
