ENTOMOLOGICAL GLEANINGS FROM ALL QUARTERS 

 OF THE GLOBE. 



Observations on Colias interior Scudder (Lepid.). 



For the past two summers I have been on a small island off the 

 Maine coast. It is two miles from Mount Desert, which, in turn is 

 half a mile from the mainland at the nearest point. It is a most de- 

 lightful island, and if it were not for the frequent and sometimes long- 

 lasting fogs, would be an ideal place in every way. 



During the summer of 1913 I caught my first specimen on July 10, 

 and in the past summer of 1914, on July 12. The first to emerge are 

 in most cases unusually large and deeply-colored males. The first 

 specimen had extremely dark yellow wings and very deep black borders. 

 The under sides were deep orange, with one very bright pink ocellus 

 on the secondaries. 



The first few males showed signs of great sluggishness in their 

 flight. They hardly ever flew more than twenty or thirty yards, and 

 then only when they were disturbed, and in a very leisurely manner. 

 About two days later 1 captured the first female of the season. They 

 were also very slow fliers for the first day, but a day later, both males 

 and females flew quite swiftly and made their capture quite a difficult mat- 

 ter, for they would not remain quiet on the approach of the collector. 

 From about July i8th to the 2ist I saw and caught only females. The 

 males seemed to have entirely disappeared. From then to July 26th I 

 caught about an equal number of each sex. Then from the 27th of 

 July they began to diminish in numbers very rapidly, until on the 6th 

 of August I caught my last specimen, a very much battered, light- 

 colored female. The previous summer I captured the last specimen I 

 saw, likewise a female, on the 4th of August. The first females, like 

 the first males, were much darker in color than the average of those I 

 caught. About the end of July I caught an almost entirely white fe- 

 male. 



I was very much interested to notice that of the four small surround- 

 ing islands only two had C. interior (during both summers). And in 

 only certain sections on Mt. Desert Island could I find any specimens 

 at all. Another curious fact I noticed was that at first I captured my 

 specimens in the open meadows, while later on I caught C. interior 

 only in open glades or fields surrovmded by woods. 



The following is a table showing approximately the relative number 

 of males and females of C. interior as observed during the two sum- 

 mers of 1913 and 1914:
