As chairman of the committee to arrange for the binding of the unbound num- 

 bers of the Journal, Mr. Schaeffer reported that he had obtained an estimate of 5 1.50 

 per volume for a binding similar to that of the volumes already bound. On motion 

 by Mr. Joutel, seconded by Dr. Wheeler, the report was accepted and the committee 

 instructed to have the binding done. 



The name of Mr. James H. Stebbins, Jr., was proposed for membership. 



Under miscellaneous business Mr. Schaeffer reported that the specimens of Lepi- 

 doptera presented to the societv by Mrs. Slosson, and to be sold for its benefit, had 

 been mounted and identified by Mr. Doll. 



The first paper of the evening was by Mr. Joutel on " Some Curious Results of the 

 Crossingof Cynthiaand Promethea Moths and Some Interesting Variations of Cynthia.'''' 

 He said he had obtained a Dumber of hybrid moths as a result of crossing Cynthia 

 and Promethea and exhibited a series of these. Of the crosses between the male 

 Cynthia and female Promethea only one moth was obtained, while from the reciprocal 

 cross a large series of moths was secured. The caterpillar of the latter cross was very 

 similar to that of Cynthia but that of the other was quite distinct in appearance. The 

 hybrid moths resembled Cynthia very much but when carefully compared showed 

 decided differences. They were uniformly smaller than Cynthia and there was a 

 narrowing of the transverse lines which tended to approach each other at their middle 

 points. These same variations, however, were occasionally found among true Cynthia. 

 Of the two crosses, that obtained by mating male Promethea with female Cynthia was 

 the stronger, and further experiments were being carried on by crossing these among 

 themselves. 



Mr. Schaeffer next spoke on " A Few New and Interesting Cerambycidse." He 

 had recently gone over his collection of Cerambycidre and noted several new and in- 

 teresting forms, some of which he exhibited and briefly discussed. 



Mr. Schaeffer also exhibited a box of insects which he had collected in Arizona 

 illustrating mimicry and protective coloration and spoke concerning them briefly as 

 follows: The grasshopper — Tomattis ferruginosus — a species with red hind wings 

 was observed moving rapidly along the road and was difficult to capture, but when 

 resting on the oak leaves where its color protected it, it made little etlort to get away. 

 He had found that the walking-stick Tarabacillns coloradus dropped to the ground 

 readily and on account of its color was difficult to find. In like manner Stagmomantis 

 limbata was also found to be well protected when resting on the grass. In beating, a 

 few specimens of the Cerambycid, Elytroleptus ignitus, were noted among hundreds 

 of the Lampyrid, Lycostomus loripes, which it very closely resembles. Another species 

 of Cerambycidse, Necydalis cavipennis, was mistaken at first for a common species of 

 Polistes which it closely resembles both in action and general appearance. A fly, 

 Dasyllis fernaldi, closely resembling Bombns ternarius, was also noticed, and the 

 moth, Tiprocris constans, taken in some numbers, could easily be mistaken for the 

 beetle Lycttis ferandezi, which it closely approaches in color, markings and flight. 

 Besides these he had observed many other instances while in Arizona. 



Dr. Wheeler spoke of a species Mantispa resembling Polistes, and Mr. Joutel 

 mentioned Euderces picipes as a Coleopteron resembling an ant. Mr. Davis described
