THE ENTOMOLOGIST. 



Sialis, and had a very short pedestal at the thicker end on which 

 they stood. Mr. Williams calls attention to the fact that the 

 " pedestal " which he describes as a " globular appendage " is 

 at the head end, and thinks that I must be mistaken in saying 

 that the eggs stood on this end. He has had the advantage of 

 seeing the ova when laid more naturally than was the case with 

 the few I figured and described, which were deposited in a chip- 

 box under anything but natural conditions. My ova were in a 

 batch (five or six) as mentioned, and certainly rested on the 

 thicker end, but, judging from the additional evidence we now 

 have, this may have been an accident. Both R. notata and 

 R. maculicollis in the imaginal state were particularly plentiful 

 with us in 1912. On May 18th in Irons Hill Enclosure they 

 could be beaten in numbers from the small oaks growing under 

 the pines, as many as five or six from a single tree. Placing 

 two dozen or so in three large pill-boxes, I was surprised on my 

 return home an hour or two later to find the great majority 

 dead or dying, the bottoms of the boxes being strewn with debris 

 of legs, antenme, &c. The few mutilated survivors were still 

 fighting, the superior size of R. notata apparently not giving it 

 any advantage over its smaller relative.
