Marsh ; and P. obsoleta, M'L., from the Lily Loch. P. striata is 

 a large insect, its nearest ally being the equally common P. grandis, 

 Lin., a species which has not yet been found in the district. 

 P. striata is a smaller and darker insect; and an examination of 

 the abdominal appendices will at once distinguish it. The two 

 species are generally mixed in collections. P. varia and P. obsoleta 

 are exceedingly alike. A good distinction is the darker piceous 

 abdomen of the latter, that portion being more ochreous in 

 varia. P. obsoleta is found in the north of Scotland and England, 

 and is also of northern distribution on the Continent. P. minor, 

 the remaining British species, is found in England, where it is 

 local, but seemingly abundant. 



Mr Binnie also exhibited Stenophylax coenosus, Curtis, from 

 Bishopton, found very rarely in the north of England, and recorded 

 by Curtis for Scotland, It is a very aberrant species, the dis- 

 tinctly truncate wings being suggestive of affinity with the genus 

 Limnophilus, from which the equality of the second and fourth 

 apical cells of the posterior wings separates it. Occasionally, 

 however, according to M'Lachlan, the fourth is narrower than the 

 second. The British exponents of the species are remarkable for 

 their small size as compared with Swiss examples. Stenophylax 

 stellatus, Curtis, from Cambuslang, and S. latiyennis, from Miln- 

 gavie, are two species usually mixed in collections ; the former is 

 generally distributed through Britain, the latter is chie% found 

 in the south-west of England, and has not been previously 

 recorded for Scotland. Plectrocnemia conspersa, Curtis, from Spout 

 of Ballagan, and P. cjeniculata, M'Lachlan, from Braemar. When 

 the "Trichoptera Britannica" was published in 18G5, only one 

 species was known in Europe. In 1871 M'Lachlan published a 

 paper in the Entomologists' Monthly Magazine, in which he 

 characterised two new species, one of which was British. P. con- 

 spersa is probably generally distributed. M'Lachlan mentions 

 only four examples of P. geniculata, three of which are British 

 (localities not known), and one from Switzerland. It may at once be 

 distinguished from its common ally, conspersa, by the. geniculate pro- 

 cess of the inferior appendices of the male ; the female is unknown. 



The Chairman exhibited specimens of Morpho gordartie (Guerin), 

 and M. aurora (Westwood), two fine butterflies from Bolivia, 

 which he believed were the first which had been brought to this 

 country ; also Morpho cypris (Westwood), and M. sidkowshji (Kolf),
