188 THE CANADIAN ENTOMOLOGIST. 



The white female of Philodice may, therefore, be a colour survival of 

 some whitish butterfly from which all the species of Colias were originally 

 derived. Some of them have still altogether white females ; while others, 

 like our Philodice, have the two forms — the older type being the scarcer 

 of the two. Northern Asia seems to be the special liome of the genus, so 

 that the original Philodice may have come to us from north-east Siberia, 

 via Alaska ; and perhaps somewhat resembled the existing Arctic Sulphur 

 (C. nastes). 



There is a small opening in the woods at Fligh Park, where Leonard's 

 Skipper is usually abundant, during the brief period of its existence as a 

 butterfly. A stream runs along one side, and grass and flowers and bits 

 of marshv g-round make it an ideal home for several members of the 

 Skipper family. 



On the 30th of August I found plenty of males there that had 

 recently emerged, but none of the other sex. By the middle of September 

 females were plentiful, but males hard to find. One wet and cloudy 

 afternoon, when all other butterflies had disappeared, two specimens of 

 Leonardus were seen resting on the flowering plants in this opening. I 

 went there on September the 27th, hoping to bring home some live 

 females and secure some eggs, but all had disappeared. So that in this 

 locality, apparently, their butterfly existence lasts for barely one month 

 out of the twelve. Many common butterflies were scarce last summer, 

 owing, I suppose, to the comparatively cold and wet season ; but the 

 Skippers did not seem to be much affected thereby, and were plentiful all 

 through the summer. 



TWELVE-SPOTTED ASPAR.-VGUS BEETLE IN CONNECTICUT. 



Crioceris 12-punctata, Linn., is an introduced species, and has been 

 working northward from Maryland, according to Professor J. B. Smith, 

 who some time ago informed me that it was present in New Jersey, and 

 would in time reach Connecticut. The first specimen recorded from the 

 State was taken by a student assistant June, 16th, 1902, who collected a 

 single specimen on asparagus upon the Station grounds in New Haven. 

 On May 23rd, 1903, I took male and female specimens from the same 

 locality. We may now expect this species to become thoroughly 

 established here as a j^est of asparagus, injuring the plants in the same 

 manner as the common asjiaragus beetle, C. asparagi, Linn. — W. E.
