 occurs in Texas, and probably in northern South America. Both

Twenty-seven specimens from Bindloe, June; Tower, June; Chat- 

 ham, May, and Charles, May. Described from the Galapagos. It is 

 very much like our common L. itiactans Koch. Does not appear to 

 have been found on Albemarle, though collecting was extensive there 

 at the proper time. 



Theridium caroliniDU Butl. ibid, is, I think, without doubt, a 

 young specimen of Lathrodectes.
