San Jose del Cabo, October. I have seen three speci- 

 mens of this species, two in the present collection and 

 one in the former lot. In general shape it is much like 

 S . -pacifica and aureola, but the head is smaller. In ap- 

 pearance it resembles magna and erndita, from which it 

 differs by the black spot on second segment.
