though visible, so we had to content ourselves by collecting 

 in the immediate viciuit}'. The season was now too far 

 advanced for many of the beetles, though Zonahris, Ccro- 

 coma, Clytanthus trifasciatns, and various Clythrids were 

 to be seen on flowers, and a Thylacitcs abounded under 

 stones, exposed to the full heat of the sun. In the sandy 

 bed of the nearh'-dried-up Eiver Adaja there was, how^- 

 ever, an abundance of interesting insects, including mauy 

 species oi Bcnibidium and Fhilonthus, Aleochara rufiiKnnis, 

 an undescribed Lathrolmm, Tachyv.sa coardata, Pxdcrus 

 ruficollis, Hetcroccrupi, Parnus, Ajyhodius, etc. 



On our homeward journey we spent a day or two at 

 both Burgos and St. Jean de Luz, but the insects noticed 

 at these places do not call for special comment. At San 

 Sebastian, however, on June 23rd, we met with Orina rugu- 

 losa, Suftr., in some numbers, on a species of Ccntaurca, a 

 species that does not appear to have been recorded from 

 Spain. 



The Coleopterous fauna of the Bejar and Piedrahita 

 districts seems, on the whole, to be very similar to that 

 of tlie Guadarrama, yet many genera are represented 

 by one or more diflferent species, as Dorcadion, Xelria, 

 Cmorrliinus, etc. The total absence of Coniferous trees, 

 so abundant at La Grauja, must, however, make a great 

 ditierence, and it is probable therefore that the Guadar- 

 rama is much the richer of the two. Unfortunately, we 

 were unable to work the higher main Gredos range, 

 though rough accommodation could no doubt be obtained 

 at one or other of the small villages lower down in the 

 valleys on its northern or southern slope. The genus 

 Dima, amongst the Elaterid^e, well known from the 

 Guadarrama, was not found by us. The Sierra de Bejar, 

 it may be noted, could be much better Avoi'ked from 

 Candelario, than from the more distant town of Bejar. 

 As regards the Hemiptera-Heteroi'jtera, several of the 

 species have not previously been recorded from Spain, two 

 of the Capsida- being new. 



The following is a list of the species of Coleoptera and 

 Hemiptera-Heteroptera taken, so far as at present identi- 

 fied. To avoid repetition the principal localities are in 

 most cases abbreviated thus: — S. Bej. = SieiTa de Bejar; 

 Bej. = Bejar; Piedr. — Piedrahita; Av. = Avila.
