The point that strikes me as curious is the making of the 

 pupal burrow in solid wood. The twig was about > inch in 

 diameter and perfectly sound. The burrow extends directly 

 into the wood and turns downward at the center. The larva 

 evidently ate its way into the twig until the burrow was fin- 

 ished, then backed out, turned around and backed in again, then, 

 sealing up the door, pupated. 



I do not know -whether this observation is new to the world, 

 but it was new to me. I should like to know (i) if this habit 

 has been noted for this species before, (2) what the normal 

 pupating habit of the species is, and (3) whether such a habit 

 as here described is known in any other lepidopterous insects. 



The moth, twig and pupa-skin are now in the collection of 

 the North Carolina Department of Agriculture, Raleigh, N. C. 



Oviposition of Tetragoneuria (Odonata). 



BY E. B. WILLIAMSON. 



In 1889 the Toledo, St. Louis and Kansas City R. R. (now 

 the Toledo, St. Louis and Western R. R.) opened a gravel pit 

 on the farm of Peter Frantz, near Bluff ton, Indiana. The 

 excavation, covering an area of about six acres, resulted in a 

 pond without outlet or inlet. For several years I haver 

 watched this bare pit acquire a fauna and flora in some 

 groups surprising in their richness. It is not my purpose here 

 to discuss this subject in any detail, but it may be remarked 

 that this pond furnished my type of Enallagina pisdnarinm, 

 since reported only from two or three stations in the extreme 

 eastern United States, and that at present the species of dragon- 

 flies taken at the pond number forty, a larger number by three 

 than can probably be taken in Great Britain at the present 

 time. 



On May 28, 1905, Tetragoneuria cynosura was found in 

 limited numbers at the pond. Tramca laccrata was a more 

 conspicuous species, many couples of which were flying and 

 ovipositing, the male releasing the female just before she 

 dipped her abdomen, catching her again deftly with his feet 

 and then seizing her head with his long flexible abdominal
