 the brown-ferruginous blotch on each side of this segment large and irregular, 

 enclosing near lateral margin a small yellow spot. Length .50 inch. 



One specimen. (Coll. G. W. Belfrage.) Very near to evechis, 

 from which it may be distinguished by the reflexed posterior margin 

 of second abdominal segment.
