52 { August, 
tibiale. Hudroporus griseo-striatus in the loch on Ben Chearan, by no 
means rare in June. H. 9-lineatus scarce, and incognitus, Sharp, two 
specimens. Colymbetes bistriatus, Agabus arcticus and Sturmii, not rare. 
Agabus Solieri, one G and one 9 on Mam Suil; possibly the first 
occasion on which the ¢ has been taken in Britain. Dytiseus lappo- 
nicus in the loch on Ben Chearan, not common. Of the dozen or 
fourteen specimens that I took by repeated visits to the loch, only three 
were females. The loch is very rocky and free from vegetation, but 
in one corner it is muddy, and has a patch of large sedges, and two or 
three large loose rocks close to the shore. Beside and under these 
rocks I found the Dytiscus. Haploglossa pulla, one specimen. Quedius 
levigatus under bark, and Hydrocyphon deflexicollis common on sallows. 
Trichius fasciatus common on thistle flowers, and Cetonia enea at sugar. 
Pyrrochroa pectinicornis, one sitting on a stump. Telephorus abdomi- 
nalis and elongatus, Elater nigrinus and balteatus, and Diacanthus 
impressus, all scarce. Astinomus edilis, one specimen brought to me. 
Otiorhynchus maurus, Magdalinus carbonarius, and Celiodes ruber, var., 
also scarce. Zeugophora Turneri, not uncommon on aspens close to the 
house. Clythra 4-punctata, one specimen. Phratora cavifrons, two or 
three, and of Cryptocephalus iabiatus, one. Donacia aquatica, not 
common; &e. 
Hemiptera in Strathglass.—In this order I was tolerably successful, 
being lucky enough to take several new species, and a few local or rare 
ones. Nysius thymi was common, but local, upon Erica cinerea. Miris 
holsatus, as usual in the Highlands, swarmed. Phytocoris popult, not 
common, upon aspen. A‘torhinus bilineatus, abounding on aspens. 
Psallus querceti, not rare on sallows; Ps. Whitei, rare, only taken at 
Rannoch before. Ps. distinctus, not common; and three specimens of a 
Psallus that Mr. Douglas considers may be P. argyrotrichus, Fieb., and 
consequently new to Britain. Unfortunately the specimens are too 
immature to admit of perfect assurance as to the species. Agalliastes 
pulicarius, not rare, and along with it Agall. Wilkinsoni. This species 
was supposed to be attached to Maianthemum bifolium, but neither 
that (which is not a Scottish species) nor any allied plant grew in the 
locality of the Agalliastes. Lygus Spinole among MMyrica. Zygonotus 
pselaphiformis, g and 9, on birch trunks, not common. Salda ortho- 
chila, not rare, on dry banks, and S. stellata, littoralis, and riparia, at 
the edge of lochs and streams. Nabis flavomarginatus, not common. 
Hydrometra odontogaster, abundant, and Coste, not common. 
Of the genus Coriva, many species were abundant. Corixa Sharpi
