( 37 ) IV. Another Entomological .Excursion to Spain. By GEORGE Charles Champion, F.Z.S., and Dr. Thomas Algernon Chapman, M.D., F.Z.S. ; with descrip-tions of two new species of Hemipteta, by Prof. O. M. Reuter. [Read February 1st, 1905.] Plate VII. The Puerto de Pajares is by no means unknown to naturalists, and even entomologists have visited the district, but so far as we know no lepidopterists have examined it. Herr Lucas von Heyden gives a rather full note on it in the account of his journey in Spain in 1805, in company with other entomologists (all coleopterists), which was published in 1870 by the Berlin Entomological Society. He especially dwells on the amenities of his quarters at Arbas, which was his pied-d-terre for the region, which reads very humorously. He found adequate quarters in the muleteers' cabin opposite the priest's residence, where men and beasts shared the lodging, and, the door being open, sudden charges of cats, fowls, and pigs were matters of course throughout the night. Arbas, Albas, Arvas, Abbas, seem to be varied spellings, of which Arbas is probably most correct and Arvas would give in English nearly the correct pronunciation. This place is about a mile to the south of the Puerto by the roadside, and consists of an old church or chapel with a priest's residence, a variety of cowsheds, of which one long row has living-rooms over and looks like a row in a colliery district. The Puerto de Pajares is at an elevation of about 4500 ft. and we selected it for our excursion, hoping to get lodgings at Arbas or at Busdongo (the town and railway station to the south of the Pass is at about 4200 ft.), or perchance at Pajares (the station to the north side of the Pass, the town being, however, below the station and rather below 4000 ft.). On arrival at Busdongo, we heard we might perhaps be put up at the " tienda " of Senor Francisco Alonzo, at the Puerto itself, and it turned out that this establishment possessed three bedrooms for travellers, and though small and over the stables and piggeries, they served our purpose, TRANS.
