white spot, both with a crooked blue line in the center and both edged 

 with dark metallic blue. On the apical part of the wing -'ire two costal 

 white spots and one white fascia, separated and surrounded by metallic 

 blue lines. Extreme apical tip golden yellow. Hind wings semitrans- 

 parent, light fuscous with dark veins. Abdomen black with a conspicuous 

 yellowish-white spot on the underside of each segment. Legs black, 

 with narrow yellowish-white annulation at the joints. 

 Alar expanse, 21 mm. 



Habitat: Mobano, Coahuila, Mexico, August. R. Miiller, 

 collector. 



Type; No. 14528, U. S. National Museum. 



This species belongs to the anrea group, but differs consider- 

 ably from any described species in the pattern of the fore 

 wing as well as in the white color of the spots. One of (lie 

 specimens, it should however be noted, has a straw-bellow 

 tint over the outer white spots. 



Mr. A. G. Hammar presented a paper on certain habits of 

 the codling moth larva, relating to the reconstruction of the 

 winter cocoon in the spring, the number of molts of the larvse, 

 cannibalism among larva?, temperature control, an un- 

 usual occurrence of two larvae passing the second winter in 

 hibernation, and the ability of some larvae to subsist upon 

 foliage. A brief account was also given on some of the main 

 results of the codling moth investigation in Michigan, and the 

 practical application of these findings. The full account of 

 this investigation will be published as Bulletin 115 of the 

 Bureau of Entomology, U. S. Department of Agriculture. 



At the conclusion of Mr. Harnmar's paper Mr. Rohwer 

 asked if, in breeding the moths, the larvae of the sawfly which 

 lives in apple had been noticed. Mr. Hammar stated that he 

 had not observed them. Mr. Rohwer said that larvae are rather 

 common in Europe and larvae with similar habits have been 

 found in Washington State. In the same genus there are 

 also larva 1 which live in plums and cherries. 



In Mr. Hammar's paper were several allusions to tempera- 

 ture control on the codling moth. These allusions led Mr. 

 Pierce to remark on the fact that although temperature has 

 a definite effect upon development, it will be found that for 

 any degree of temperature the development will vary with the 

 humidity, this variation sometimes being of considerable degree.
