Exhibitions, dc. 



Mr. F. P. Pascoe exhibited some remarkable insects' nests from Delagoa 

 Bay. They varied from half an inch to an inch and quarter in length, and 

 in shape from globular to ovate. They were semitransparent, yellowish, 

 and the surface, under a lens, had a reticulate appearance ; on one side, 

 from the base to the apex was a stout suture, to which was attached a 

 septum extending about two-thirds across the interior; on each side of this 

 septum, but away from the suture, were placed in an erect position about 



120 cylindrical eggs. These nests had much the appearance of the dried 

 pods of the " bladder senna ; " they were retained by a movable loop to the 

 slender twigs of a shrub which Sir Joseph Hooker had pronounced to be a 

 Rhammis. 



Mr. R. M'Lachlan considered that these curious bladder-like egg-cases 

 belonged to one of the Mantida. 



Mr. Wood-Mason did not think they should be attributed to the 

 Mantidce, although possibly it might be so ; he pointed out that the eggs 

 were arranged in quite a different manner to those of any Mantis he had 

 seen. He also suggested that the large vacant space existing between the 

 egg mass and the outside of the capsule would probably be protective 

 against parasitic insects. 



Mr. T. 11. Billups exhibited specimens of Pachylarthrus smaragdimis, 

 Curt., bred on December 1st from the pupa of Acidia heraclei, Linn. — the 

 celery fly.
