132 THE entomologist's recokd. 



extent and vividness ; some specimens have no eye-spots on the hind 

 wing ; the eye-spots are usually white in black rings, but in three 

 specimens the white eye-spots appear without rings, and in others 

 there is a black eye-spot only. In addition to these more or less 

 typical forms, seven specimens are of the Swiss form filarialis, with 

 mahogany bands but no eye -spots ; there are two ab. pliito (as at 

 Karersee) ; and two without mahogany, but with white spots in black 

 rings, not, however, as prominent as at Campiglio. Of the five $ s, 

 three are typical, one with white eye-spots minus the black rings, and 

 one of the form iilacialia. Many of these butterflies are very beautiful, 

 but the most striking are those taken at Madonna di Campiglio. 



E. vianto. — Swarming at Brenner. The specimens shew con- 

 siderable variation ; the eye-spots are sometimes absent on the upper- 

 side ; and in some cases the red-brown patches have also almost 

 entirely disappeared, these specimens approaching closely to the 

 Pyrenean form caecilia, = <javarniemis, Warren. 



E. ceto. — This species was in very good condition on the Mendel 

 Pass on June 29th, 1911, but was quite over a fortnight later. 



E. medum var. hippomediisa. — This insect was swarming at Karersee. 

 In both sexes the specimens shew variation in the number of eyespots, 

 both on the front and on the hindwing. 



E. nerine. — In both years ^ s Avere very plentiful on the Mendel 

 Pass in the middle of July. 5 s were not yet out in any numbers, 

 though we took a few. In the large majority of specimens examined 

 (and -vve captured far more than we kept) the tawny bands on the 

 upperside are very conspicuous ; but in a few instances they become 

 inconspicuous and then on the upperside the insect bears a decided 

 resemblance to the redder forms of E, lefehvrei, though less ocellated. 

 Most of these instances differ from the type in the underside of the 

 hindwing also, the toothed band, which is very conspicuous in typical 

 specimens, being entirely wanting. In 1911 my wife took an extreme 

 form in which the insect is of an almost uniform black on the upper- 

 side, but with white ocelli on all four wings. On the upperside this 

 specimen closely resembles E. nielas, the black form of E. lefehvrei, 

 and the form of E. alectu var. nicholli. 



E. euryale. — Generally distributed. It is worth noting that while 

 in 1911 this insect was swarming on the Mendel Pass in the middle of 

 July, scarcely any were observed there at the same period in the 

 following year. 



E. %ga.— Mendel Pass. 



E. gorge. — The type was taken at Brenner and Karersee, including 

 in the latter locality a fine example of ab. erinmjs, with no sign of 

 apical eyes on the upperside. At Trafoi we took only var. triopes ; and 

 the same was the case at Sulden, except that amongst the ? s taken 

 there were two specimens of the type. 



E. tyndarus. — Generally distributed, but specially in evidence at 

 Sulden. One of the specimens taken at Brenner and one at Karersee 

 approached closely to ab. droDtiis of the Pyrenees. At Sulden we took 

 specimens of ab. caecodromns, both ^ and ? . 



E. lappona. — Generally distributed.
