Mr.D. J. Rice exhibited nest and eggs of the Creeper {Certkia 

 faniiliaris, L.) ; and eggs of Wren {Troglodytes parvuliis, 

 Koch.). 



The Secretary, on behalf of Mr. T. D. A. Cockerell, 

 exhibited specimens of Trichodes ornahts, Say., Chrysis 

 pacifica, Say., and Caittharis nuttalli, Say., from Colorado, 

 and read the following note : — 



" CantJiaris nuttalli, Say. This species of Cantharis, kindly 

 named for me by Prof C. V. Riley, is exceedingly abundant 

 in this locality (Custer Co., Colorado), being gregarious on 

 low plants and very conspicuous. W. L. Carpenter has 

 already recorded this species from Colorado (Ann. Rept. U. 

 S. Geol. and Geog. Survey for 1873), and he states that he found 

 it only very locally in South Park, where it was confined to Iris 

 inisso7iriensis, Nuttall (or as he calls it, ^' Iris tenax"), and 

 seemed to be protected by its resemblance to the colour of 

 that plant. I cannot, however, quite agree with this view, 

 because here it is certainly a very conspicuous beetle, and yet 

 does not appear to be eaten by birds — indeed one might well 

 suppose that a species of Cantharis would not be palatable. 

 Neither is C. mittalli always confined to Iris — I have indeed 

 found it in plenty on Iris viissoiiriensis here, but even more 

 abundantly on leguminous plants — particularly Thennopsis 

 and Oxytropis lamberti. 



" The other two species of insects exhibited are Trichodes 

 ornatiis, Say., and Chrysis pacifica. Say., — mentioned in a 

 former note read before the Society as being frequent on the 

 flowers o{ ligiistiann montaninn in this locality. I have also 

 observed both species on Geranium fremontii, but more rarely, 

 and on one occasion I found T. ornatiis on the flower-head of 

 Achillea millefoliiiniy 



The Secretary also read the following notes from Mr. T. 

 D. A. Cockerell :— 



"The genus Eiichloe { = Anthocharis). — Darwin, in the 

 Descent of Man remarks that although the males of certain 

 species of this genus have orange-tips, those of others, like the 

 females, lack them, and suggests that these latter are nearer 

 the original type of the genus. E, ausonides, Bdv., a species 

 found in this locality, and ranging northward to Alaska, is 

 one that lacks the orange tips, and is probably the most
