Rhithroijena semicolorata , Curt., very common. R. sp. 1, R. sp. ?, 



R. sp. ?, these three forms may only be varieties of semicolorata, but they differ 



very considerably from that species, but owing to not having specimens preserved in 

 fluid, they cannot satisfactorily be made out. 



Ileplagenia elegans, Curt., common. II. longicauda, Stc., everywhere. S. late- 

 ralis, Curt., a few were taken. 



Odonata. , 



Leucorrhinia dubia, Van d. Lind., one specimen was taken in Glen Cannich. 



Sympetrum striolatiim, Charp., common. S. scoticum, Don., abundant in Grlen 

 Cannich. 



Libellula quadrimacnlata, L., near most of the Lochs. 



Cordulla metaUica, Van d. Lind. ; a few specimens were taken after much hard 

 work. C. arctica, Zett. ; I have a specimen of this species in my cabinet taken by 

 Dr. Buchanan White, many years ago in Strathglass, but I was not fortunate in ob- 

 serving the species myself, although Dr. White gave me all the assistance he could. 



Cordulegaster anntdatus, Latr., in many localities. 



uSSschna juncea, Miill., abundant in all the Grlens. 



Pyrrhosoma minium, Hans., a perfect pest at all the Lochs. 



Agrion cyathigenim, Charp., equally common with the last species. 



This gives as the result of my trip 111 species, or, excluding the 

 four doubtful species of Ephemei-ido', 107, more than half this number 

 being taken up with the Trichoptera, namely, Qo ; the Neuroptera- 

 Flanipennia absorbing 13 ; leaving the remainder for the Pseudo- 

 Neuroptera. 



In conclusion, I have only to acknowledge the kindness with 

 which my friend Mr. McLachlan has unravelled many of the more 

 knotty points among the Trichoptera, and the assistance I have re- 

 ceived from the Ecv. A. E. Eaton when working at the Ephemeridco.

THE TARSAL AND ANTENNAL CHARACTERS OF PSOCIDM. 

 BY PROF. H. A. HAGEN. 



By a mere chance I see that a statement recently published by 

 me concerning the tarsal structure of Psocidw confirms, in a most 

 satisfactory manner, that made by Prof. Westwood in 1857 (Proc- 

 Ent. Soc. Lond., series 2, vol. iv, p|). G3, 04) regarding certain Coleo- 

 ptera. 



Being occupied with the Atropina, I was astonished to find that 

 the young forms have only two-jointed tarsi (instead of three-jointed, 

 as is found iu the imago), but the last joint, internally, in the middle, 

 shows a more or less visible di\ ision, where the 3rd joint (the median)
