I take this opportunity of stating that it is highly desirable a 

 revision of the North American species of Panorpa should be made. 

 The species were mostly described by Klug, "Westwood and Hagen. 

 The types mostly exist in Berlin, London and Cambridge (Mass.), 

 and in each case under circumstances that foi'bid their being " com- 

 municated." When the descriptions were written the crucial specific 

 characters were not fully understood ; neither was the variation from 

 local causes that undoubtedly influence some species.

NOTES ON TRICHOPTERA (INCLUDING AORYPNIA PICTA, Kol.), 

 TAKEN IN UNST (SHETLAND), 1895. 



BY JAMES J. F. X. KING, F.E.S. 



Last season, while in Unst, I picked up, rather than collected, a 

 number of Trichoptera, and as all notes of captures from this northern 

 isle are interesting, I make this my plea for bringing forward this 

 short sketch. 



I recorded 32 species in this Magazine as having been taken by 

 myself in 1889. In these notes I only mention 27 species, but three 

 of these are new to the 1889 list, namely, Agrypnia picta, Limno- 

 philus stigma, and Micropterna sequax. The reason why there is such 

 a difference in the total number of species taken in the two seasons is 

 to be found in the fact, that in the former year I devoted almost all 

 my time to the Triclioptera, and last year to the Lepidoptera. 



The species which so far was the most interesting of the Unst 

 Trichoptera is Mesophylax impunctatus, McL. ; to this I devoted a con- 

 siderable amount of attention, but 1 am sorry to say with but poor 

 result last season. In 1889 this species occurred more or less all over 

 Crussafield, flying at night along the little streamlets which had hollowed 

 out a ditch-like course in the hard ground : by sweeping the herbage 

 which grew along these courses the species might be taken in company 

 with BhyacopTiila dorsalis in the proportion of one to about fifty of 

 the latter. Since my visit in 1889 the aspect of Crussafield has been 

 changed, for where we used to find deep channels, we now have a 

 swamp and no place for the insects to hide, in fact, on this ground 

 where formerly I might have taken hundreds of R. dorsalis, I do not 

 believe I saw over a score, and not one of the rare species. However, 

 when searching for Uepialus himuli a few specimens were caught on 

 the wine: near Loch of Cliff.
