Cleveland Neuroptera and Trichoptera.—In connec- 
tion with the recent meeting of the Yorkshire Naturalists’ 
Union at Great Ayton, Mr. T. A. Lofthouse, Mr. Samuel 
Walker and I spent the week-end, August 2nd to 5th at Kildale- 
in-Cleveland. My own work was almost entirely among the 
Neuroptera and Trichoptera, and I was greatly assisted by Mr. 
Lofthouse. Of the twenty-one species taken, eight belonged 
to the genus Hemerobius out of eighteen recognized as British, 
showing that these insects must be well represented in the dis- 
trict. The interesting Hemerobius orotypus was abundant 
among conifers, and the pretty H. marginatus was also common 
among other trees, but away from the pines and firs. 4. 
atrifrons was secured by Mr. Lofthouse, singly as usual. It is 
curious that this species seems to be always taken singly—or 
at most a couple. I only remember, indeed, one occasion on 
which I took a couple of specimens on the same day, and they 
both came out of the same bush in Wharncliffe Woods; and 
such is apparently the experience of neuropterists throughout 
the country. Most of the other species of the genus can usually 
be found in numbers when they occur at all. The most inter- 
esting Trichopteron was the neat Leptecerus bilineaius which 
was fairly common both at Kildale and Great Ayton. The 
list 1s as follows :— 
NEUROPTERA. TRICHOPTERA. 
Chrysopa flava. Glyphotelius pellucidus. 
50 flavifrons. Limnophilus centralis. 
Hemevobius ovotypus. #9 auricula., 
AM marginatus. BY gviseus. 
Bs quadvifasciatus. 5% sparsus. 
ia subnebulosus. Silo pallipes. 
9 micans. Leptocerus bilineatus.

5: stigma (limbatus). Polycentvopus flavomaculatus. 
x atvifrons. The last at Great Ayton only.
