and floods produce any marked diminution in those species 

 of insects which pass the winter beneath ground, as com- 

 pared with those which hybernate in sub-aerial retreats. And 

 the comparison will be a fairer one if the winter should pass 

 over without severe frosts. — fV. H. Groser ; 19, Claremont

Papilio Pammon : its alleged Polipnorphism. — Papilio 

 Pammon is very common in the Sewalik range of the Hima- 

 layas, at the point vvhei'e the Ravee enters the plains of the 

 Punjab, not being by any means so abundant farther west. 

 It is double-brooded, and is generally found hovering over 

 Adhatoda Vassica, which I suspect to be the food-plant of 

 its larva, though I have never come across the latter : the 

 first brood appears in April and May ; the second, and by 

 far the less numerous, in October. What has struck me, in 

 connexion with its alleged polymorphism, is that Papilio 

 Polytes, its female form, has never been remarked by me as 

 occurring in company with its second brood, though it is on 

 the wing together with the first brood of P. Pammon. The 

 tailless form of P. Theseus, and its variety P. Romulus, have 

 never been observed by me. In the station of Sealkote, 

 situate in the plains, twenty-six miles south of the Sewalik, 

 I have captured several specimens of P. Polytes, but never 

 one of Pammon. P. Polytes I have also taken at greater 

 altitudes than P. Pammon, and later in the season ; these, 

 however, might have been stragglers. P. Theseus also occurs 

 in the Sewalik, but not in any numbers. The result of three 

 years' observations leads me to believe that P. Polytes, at all 

 events in this part of the Punjab, occurs both farther in the 

 plains and higher up in the Himalayas than P. Pammon. —

Colias Edusa, var. Helice, in Sussex. — On the 9th of June, 

 1865, my brother captured a specimen of Colias Edusa, var. 

 Helice, as it was flying over a piece of wheat in this parish. 

 This is a larger specimen than any of the ievf I have myself 

 seen, measuring in the expanse of the fore wings two inches 

 four lines. Colias Edusa not generally appearing here before 

 the third week in August, the occurrence of this variety so
