shield. The usually decisive character of the position of tubercle iv. is 

 here as indifferent as it could possibly be made. I explain the larva as 

 follows : It is at the bottom of the Bombycids, and tubercle iv. has not 

 yet taken up its definite position. The other Tineid anomalies are 

 explained by a comparison with the Drepanidai, with which this larva 

 bears affinity in the setos, although there is no hypertrophy of the anal 

 plate. In Drepaiia arcuata the thoracic tubercles ii.a and ii.b are united, 

 the epicranial seta viii. is high up, above the level of the eyes, and abdom- 

 inal tubercle vi. is doubled, all as in Callidapteryx. Drepana is then also 

 a low form, but here abdominal tubercle iv. is in the characteristic 

 Bombycid position. 



The Epipleraidae, then, stand at the bottom of the Bombyces, throw- 

 ing off on one side the Drepanid», on the other (judging from the moths) 

 the Geometrida3. Near them the Notodontian stem has arisen, giving 

 rise to the other Bombycid families. (See Proc. Boston Soc. Nat. Hist., 

 XXVII. , 146, for a geneological tree. The Epiplemidse may be added at 

 the point where the stem of the Drepanidfe joins that of the Geometrise.) 



Callidapteryx dryopterata, Grote. 



The larvpe were found abundantly at the end of July on Viburmiin 

 nudum. Moths emerged August i6th, and eggs and young larvae were 

 found immediately after. Pupaj by September 6th between leaves. 

 Evidently two-brooded. No description accompanies these notes in the 

 books of the Department of Agriculture, and I do not think an adequate 

 one can be made from the blown Jarvfe. They may have been green or 

 whitish with broken brown lines, tubercles i. and iii. large and dark, the 

 rest pale. Head spotted, 1.4 mm. wide. There is no record of whether 

 the larvse were exposed or concealed feeders. Stage I. is preserved 

 mounted on a slide labelled 3/4/92, No. 2826, but so badly shrunken that 

 I cannot see the arrangement of seta^. Feet slender, the crotchets nearly 

 bordering the planta, anal plate prominent but not produced ; setse large. 



The Toronto Branch of the Entomological Society of Ontario 



held its second annual meeting on the ist of April last. The following 



officers were elected for the ensuing year : President, Mr. R. J. Crew ; 



Vice-President, Mr. C. T. Hills; Secretary-Treasurer, Mr. Arthur Gibson; 

 Librarian-Curator, Mr. H. D. Chipman ; Members of Council, Messrs. 

 H. C. Tyers and E. M. Fenwick. The Department of Education for 

 Ontario has granted to the Society the free use of a room in which to hold 

 its meetings and place its library and collections.
