Parasitic. Branches shorter and thicker than in the pre- 

 ceding species. In the shape of the area they are very 

 much ahke, but in S. bicornis, in. some cells, and occa- 

 sionally throughout the greater part of the intemode, the 

 area differs widely from the more usual form. It is much 

 expanded, and presents a wide arch above. In this case 

 there is usually a considerable-sized perforation above the
