92 THE ENTOMOLOGIST. 



E. tithonus was scarce. I saw a few specimens at bramble blossom early 

 in August. E. hyperanthes was distributed about the woods, and was 

 partial as usual to bramble blossom. I took a specimen of the variety 

 arete, with each eye-spot barely indicated on the underside by a white specie. 



Ccenonympha arcanius, occurred from June 20th till the end of July, 

 and was common on all grassy places, and in the more elevated meadows. 

 C. jjamphilus was abundant everywhere. 



Thecla hetulce I saw rarely in the perfect state, flitting on the outskirts 

 of woods. The larvae were abundant on sloe in May and June, from 

 which I bred several imagines. T. ilicis was fairly common but local 

 from June 25tli on the blackberry blossoms, from which they were easily 

 taken. I subsequently saw two or three at the wild thyme. T. quercus 

 was scarce. I netted two or three during July. T. rubi, though supposed 

 to be double-brooded here, did not put in an appearance a second time, but 

 was very abundant in May and first half of June. 



Polyommatus virgaurecB was scarce. They prefer the more highly 

 situated meadows in the woods. I netted about eight females during the 

 first half of August, and only two males. P. chryseis was also not common 

 and decidedly local, preferring the marshy spots in the meadows, where one 

 might meet with one or two specimens by some hours' hunting. I took 

 more males than females of this species, possibly owing to their being so 

 much more conspicuous. Chryseis is single-brooded, and occurred during 

 the latter half of June. P. dorilis was the most abundant of the " Coppers," 

 it being apparently double-brooded, and occurred most commonly during the 

 last half of May and first half of June, and then in greater profusion in 

 August. The great difference between the males and females of this 

 species, both as to markings and outline of the wings is somewhat puzzling 

 at first. The tawny patch in the centre of the forewing of the male, 

 varies very much in extent and brilliancy. P.phlceas occurred at the same 

 times as P. dorilis, but was not nearly so abundant. 



Lyc(B)ia argiades occurred but very sparinglyjin May, in the small form. 

 I netted only two, a male and female of this first brood, and saw one other. 

 The large form, the second brood, was far more abundant, preferring any 

 piece of open rough ground to the meadows in woods, where I did not 

 once observe it. Some disused quarries of limestone produced it most abun- 

 dantly, but one met with it occasionally all over the tracks intersecting 

 the cultivated ground. L. agon was double-brooded and abundant. Large 

 specimens of the second brood seemed to correspond to insects I saw named 

 as L. argus in European collections, but I was unable satisfactorily to 

 distinguish the two, so am not sure whether I met with the true L. argus 

 or not. L. corydon is not supposed to inhabit the Taunus Hills, neverthe- 

 less I met with two odd specimens in different places not on chalk ; one on 

 July 22nd, and the other on August 14th. It is said to be abundant at 

 Mayence, eight miles from Wiesbaden. L. baton, Bgstr. [hylas], occurred 

 in May and July, and was geneially distributed in the meadows in woods. 

 They appeared far more abundant during July than in May. L. astrarche 

 was scarce. I met with one or two on some broken ground during July 

 and August. They were like our southern specimens, but rather larger 

 than usual. L. icarus was very abundant everywhere and triple-brooded ; 

 specimens of the third brood were very diminutive in size. L. hellargus 

 is not supposed to occur at Wiesbaden, but is abundant on the other side 

 of the Rhine opposite. In September of J 887, however, I took several
