Trichoptera. 
The Recorder has published (P. L. S. xi. pp. 98-141, pis. ii.-iv.) 
a paper On new forms, &c. of extra-European Trichopterous 
Insects, which he prefaces (pp. 98-101) by some remarks on their 
position in the system, especially with regard to Packard's view 
of them as comparatively degraded forms of the order Neuroptera 
(which he retains nearly in the Linnsean sense), and expressing 
an opinion that they probably form a separate order, manifesting 
considerable affinity with the Lepidopteraj and but little, if any.
