Eggs. — Shortly elliptical, nearly spherical, one diameter a little less 

 but no flattening or truncation; about 14 longitudinal ribs, low, dis- 

 tinct, running to the antemicropylar end w^here the}' meet in a slightly

 which represents the edge of the obsolete truncation; end reticulate. 

 Ribs nearly straight, dotted faintly with two rows of pores; cross

 fine adventral line. Joints 2—1 and 10-13 marked over the yellowish 

 with clouded dorsal and subdorsal purple-brown lines. Cervical shield 

 and anal plate darkly sordid shaded. Feet dark, nearly black; the
