88 THE kntomoi^ogist's rkcord. 



that must have been <). antiqua, though it may have been one of the 

 (). crirac group, with whose larvRP I have no acquaintance; whatever it 

 was, it seemed odd to get one, and one only. Larva of Thcda ilicis 

 (and iipini .'), and of Orneria rnbea, were also fairly common on the 

 oak-scrub, as well as of Malaco.^oina neiistria, whilst those of Malaeosoma 

 franconica was often met with in odd examples on low growing 

 plants. A very handsome larva (possibly Lachncis raia.r) also 

 occurred on the oak, and a lai'va and a cocoon of Pharodi'siua jiustiilata 

 were taken. 



The oak also afforded several larvse, none of which were reared, 

 which were most probably Tricldura (/) iUcifi. 



The most interesting species on the Oem'sta scnrpias. was the Hetero- 

 !l!/)iis, which has characters so far distinguishing it from the two 

 recognised species of the genus, as to justify its claim to separate 

 specific rank, though it is in many respects very close to //. penclla. T 

 propose to call it ranah'nais from its habitat. It is larger than H.pcnella, 

 has shorter cilia, a different tint on upper and lower wings, and is 

 especially different in the peculiar elaboration of the female cocoon, 

 with a corresponding difference of habits. [See Trans. Knt. Sac. 

 Lorn}., 1904.] 



Although we reached Canales from the west, we found that the 

 more regular way of approach is from the northeast, dz., by the valley 

 of the Najerilla, in the upper valley of which Canales is. There is, in 

 fact, a diligence service along this valley from Canales to Logrono, on 

 the main railway line to Saragossa. This service is of a rather 

 primitive and limited character from Canales to Mansilla, the first 

 stage, and traverses a country very similar to that around Canales. 

 Departing by this diligence, we were able the first day to reach 

 Aguiano. Between Mansilla and Aguiano, the valley of the Najarilla, 

 is one of the most picturesque defiles I have ever visited. The deep 

 cutting the river has made serpentines interminably, and one often sees 

 no way out in front, the banks are steep and broken by high and bold 

 precipices, and varied by hanging woods, the dominant colour was 

 derived from the great masses of the Gem'sta (like jiorida) seen at 

 Canales, which here abounded in great masses, but the colouring was 

 very varied by the rocks and trees, and the yellow never became 

 monotonous. 



Aguiano is situated at a point where steep sharp ridges of rock 

 nearly meet on each side of the stream, and with the high precipices 

 they fall back into, and which follow the stream above and below, 

 make a passage practically impassable till engineered, and no doubt 

 most easily defended in times when that was a primary consideration. 



Below Aguiano, whence we proceeded the following morning, the 

 valley is more open, but still very picturesque at very many points. 

 At Aguiano we saw LiuriuKs rern(s somewhat freely on the wing, it 

 seemed a spot where good collecting could be done, especially somewhat 

 earlier in the season. The diligence left Aguiano at 4 a.m., and we 

 had the pleasure of starting Avithout breakfast. We got on the same 

 day by train from Logrono to Tudela and Tarazona.
