and those in the South Pacific, though small and mostly barren, might 
serve as stepping-stones in its progress. The distances between these 
Islands, though great enough, are nothing like the first great step 
from Aumeriea, “ho the Sandwich Islands, am not more than the heht 
or downy seeds of the Asclepias could be carried by the agency of winds, 
&e. It is significant, too, that the Pacific specimens all agree with 
the North American forms, the larger pale spots in the black apical 
portion of the forewings being tawny, not white as in those from the 
Peruvian coast of South America. The same remarks may apply to 
its dispersal across the Atlantic, but owing to the much more stormy 
character of this ocean, and the less steady winds, the chances of the 
butterfly crossing a given extent of ocean in safety are less favourable. 
Walker concludes his excellent paper (loc. cit., p. 223) with a lst of 
the localities from which the species has been sent or in which it has 
been observed, and which is much too long to be repeated at length here. 
In the history of the distribution of these insects—Anosia archippus, 
Pyrameis cardui, Colias edusa and ('’. hyale—we see, then, a fight 
carried on in nature against climate and other powerful forces, by 
butterflies of strong flight and great activity, with marvellous powers 
of endurance, and with great energy and reproductive ability, in which 
the excess of fecundity is, to a great extent, wasted, and thus we observe 
how it is that such species are prevented from becoming pests, as they 
most certainly would do if the whole of their progeny had to be 
supported within the comparatively narrow limits in which they are 
able to exist throughout the whole year.

THE EGGS oF CtyrHra 4-puncrata.—The eges described (ante., p. 218) 
by Dr. Chapman were laid by a specimen of Clythra 4-punctata I had bred 
from a pupa-case taken in the Blean Woods. I puta male and female 
in a glass-topped box. Soon after copulation the male died. The 
female laid twelve eges and then died. I sent these eges to Mr. Tutt, 
as I was just off to Scotland, and was afraid if I left them at home the 
young larve might hatch and die, and if I took them with me the eggs 
might get damaged. In writing to Mr. Tutt to ask if the eges ihatighe. 
before I had seen Dr. Chapman’ s second note, I suggested that the 
beetle might lay the eggs in nature on, or in, the ant hillock, and that 
all the eggs might then have capsules to serve the young larve as a 
protection till they had had time to make cases for themselves. Dr. 
Chapman evidently takes the same view of the use of the capsule.—

CoLEOPTERA AT CHIDDINGFoLD.—Haying run down to Chiddinefold 
for a night on June 16th, I took the opportunity to visit my Quedius 
kraatzw stream, although it was later than I have taken the beetle 
before. It was evidently nearly over as only one or two specimens 
were seen, I took a fine male, however. Other species were Deinopsis 
erosa and Platambus maculatus, a very variable series of the latter being 
taken. I noticed a specimen of Drusilla canaliculata in the porch of 
the cottage where I stayed, which was running about with something 
in its mouth ; this proved to be the dead body of an ant, and is very 
interesting as pointing out what its food may be and why it often 
occurs with ants.—Ism.
