PSYCHE. 



[March — April iSqo. 



cattis. Harris in his catalogue (second 

 edition 1835) has first mentioned Say's spe- 

 cies and in his manuscript catalogue records 

 receiving the same from "Doct. Gould, an- 

 other from Dr. Smith." This entry is in- 

 serted between specimens collected in May 

 and June, 1831. Prof. Riley in his third 

 Missouri report (1871 p. 11) states that the 

 species infests the crown of strawberries but 

 does not say where it was observed. Pro- 

 vancher speaks of the species as "tres com- 

 mune." Lintner in his second report (1885 

 p. 51) mentions it as injurious to bulbs and 

 house-plants. I do not find the species re- 

 corded west of Pa. In the European litera- 

 ture it is mentioned everywhere and the early 

 stages are described by Bouch6, Westwood, 

 Lucas and others. H. A. Hageu. 



Notes on Colias elrytheme and C- 

 PHILODICE. — In the vicinity of Charleston. 

 S. C, where most of my observations have 

 been made, Colias eurytheme is the charac- 

 teristic type. I may say, in fact, that it is the 

 only member of the genus that I have ever 

 seen on the seaboard. It is as plentiful there 

 as C. philodice usually is in its proper range, 

 though not seen, as far as I know, in the 

 countless hordes in which the latter is said to 

 congregate at times. In Clarendon County, 

 S. C, where I have collected, oft" and on, for 

 a good many years, C. eurytheme was not as 

 abundant as on the coast, C. philodice not 

 found at all, and C. caesonia taken occasion- 

 ally. In Ashville, N. C, where C. fhilodice 

 is very abundant, I have never seen C. eury- 

 theme; and C. caesonia but once. Spartan- 

 burg County, S. C, is the highest locality in 

 which I have yet found C eurytheme. 



I have never seen C. philodice at all in 

 South Carolina imtil this autumn; at which 

 time I was enabled to do considerable col- 

 lecting in Columbia, a locality where I had 

 never collected before. Here I found C. 

 philodice and C. eurytheme occurring in equal 

 and considerable abundance, and this spring 



I meet C. philodice and C. ariadne in about 

 the same proportion. I have noticed a de- 

 cided difference of manner between the two; 

 C. eurytheme being much swifter in flight, its 

 stop at a flower less prolonged, and its whole 

 manner more decided; and it is also much 

 more wavy and therefore more difticult to 

 catch than C. philodice. In this respect, my 

 experience is, to use an equation, that C. 

 philodice: C. eurytheme :: C. eurytheme : C. 

 caeso?iia. 



Our normal spring form of eurytheme is 

 C. ariadne. I have taken, this past January 

 (i2th to 24th et seq.) a large series of C. 

 ariadne, which are, on the average, identical 

 with forms from Texas, and show no marked 

 variation from a few that I have from Wis- 

 consin. A pretty full series of western C. 

 eurytheme in my collection, consisting of 

 specimens from five states, from Wisconsin 

 to California, present no marked difference 

 from our autumn eurytheme; possibly in one 

 or two cases, the western form may be a trifle 

 more irridescent than our average; but I 

 have one July $ taken in Charleston, that is 

 fully as rich in color, as any that I possess 

 from the west. I notice among these western 

 forms some that appear to me to be unmis- 

 takably C. keeivaydin: this form I have not 

 taken here, though I have a few C. ariadne 

 from Charleston that are very large and yel- 

 low and seem to intergrade with C. keetvay- 

 din. 



The autumn $ ^ o{ C philodice taken in 

 Columbia are much larger than northern 

 forms of the same in my collection from 

 Princeton, N. J. We have a spring form of 

 C. philodice, bearing the same relation as far 

 as size is concerned, to the autumn C. philo- 

 dice, that C «r/rf«e bears to C. eurytheme. 



In the city of Charleston, I have taken the 

 eggs of C. eurvthcme from white clover, as 

 they were laid by the female. 



The white $ $ of both C. eurytheme and 

 philodice I have taken here, in Columbia, in 

 spring and autumn. 



C. caesonia, the only other of the genus 

 found with us, is by no means abundant, 

 though not infrequent last autumn. I cap- 

 tured six in Columbia, in October and No- 

 vember, 1S89. Elisoii A. Smyth. Jr.
