joints densely short golden-yellow pilose. Wings hyaline, small cross- 

 vein at middle of discal cell, base of third submarginal cell at last fifth of 

 distance between small cross-vein and apex of discal cell ; costa not en- 

 larged. On the anterior part of the second abdominal segment are many 

 rather large, transversely-elliptical punctures, and similar punctures also 

 occur on some of the other segments. Antennae similar in structure to 

 those of pern ids. 



$ same as the $ , except that the pollen of the abdomen is darker, 

 and the pile is shorter and sparser ; ovipositor as long as the fifth, sixth 

 and seventh abdominal segments taken together. 



Length, 20 to 25 mm. Los Angeles County, Cal. Six males and 

 four females. 



NOTES ON COLLECTING SOME OF THE SMALLER SESIIAD^E 

 IN THE LONDON (ENGLAND) DISTRICT. 



The one most commonly met with is 5. tipuliformis, and is to be 

 found sunning itself on the leaves of the currant bushes at the time when 

 the fruit is about two-thirds grown, and on a bright sunny morning about 

 10 o'clock, or afternoon about 4 o'clock, one can easily take from six to 

 twelve in one or two hours. Once I found them assembling, and took 

 some thirty or forty in a very short time. It is a little difficult to procure 

 the larvae, as they feed in the two-year-old wood, and, as this is the fruit- 

 producing part, it is better not to cut it while the owner is about, and when 

 you can cut, I have found so many blanks that the bushes have suffered 

 more than the gain warranted. 



The next species commonly met with is our red-banded one, 

 S. myopaeformis, feeding in the bark of apple trees (about six feet from 

 the ground), and can generally be found in gardens where Tipuliformis 

 is found. I have never seen this moth at rest, and though one can gener- 

 ally count on taking several in a morning, one must watch the trunks of 

 the trees and find them flying round and round, evidently for depositing 

 eggs ; cutting out the larvae without doing much damage to the tree is 

 hard, as they feed just under the bark. 



Our next commonest one is 6". culiciformis. For this we must go 

 to the woods where birch is common ; so, taking the train down to 

 Croydon, ten miles (about the end of April), a two-mile walk brings us to 

 West Wickham Wood, one of our best in the South London district. We 

 go through it till we find a part which was cut down two winters back ;
