152 ENTOMOLOGICAL NEWS. [April, '13 



fed on the tender leaves or flowers but required the seeds in 

 the later stadia. This is the method that obtains with argiades 

 and certain others of the Lycaenidae, and it is quite possible 

 to be the habit in more northern localities, where it is not an 

 uncommon species. I am not forgetful of Mr. W. G. Wright's 

 most interesting account of the larvae of this species (Papilio, 

 IV, p. 126). The description of the newly-hatched larva, 

 piercing immediately into the seed pod and then, after a short 

 time, sealing up its entrance and making it water-tight, is of 

 the greatest interest and no doubt applies generally to the Cali- 

 fornian race. He speaks, however, definitely of a later brood 

 hibernating probably as larvae. (This would agree with the 

 habits of our European argiades.) Unfortunately I cannot 

 make out whether there is a real second brood or not, as no 

 dates at all are given. In Canada the general consensus of 

 opinion is quite definite that there is but one brood, though of 

 course it is possible in the more favored climatic conditions of 

 California that there may be a second brood, or at least a 

 partial one. Mr. Wright also definitely states that the larvae 

 are not myrmecophilous and that they actually seemed to 

 shrink from the touch of the ant's antennae. Here we have 

 also a close similarity of habit to our argiades as, though Chap- 

 man notes a honey gland, I have been unable to trace any 

 record of their association with those insects. 



Turning now to the genitalia we find the highest develop- 

 ment in the Californian specimens and this has taken place ir- 

 respective of size. I took several from San Diego and matched 

 them in size with others from Utah, Calgary and Vancouver, 

 all of which are figured. It will at once be seen that the Cali- 

 fornian example has much the largest prehensores, and this 

 obtains generally. Those from Utah are next in dimensions 

 (though much smaller than the San Diego race), but they are 

 run very close by those from Vancouver, whilst the Calgary 

 specimens are well the smallest, and this with insects practically 

 of the same size. 



In the Californian specimens the clasps are very large, with very 

 long hook-like extremities, the apices of which are shagreened very 

 roughly and some way down from the apex itself. This shagreening
