20 THE CANADIAN ENTOMOLOGIST. 



Zoological Museum, Cambridge, U. S., Dec. 20. 

 Dear Sir, — 



I have commenced to study and arrange the Coleoptera in the 

 Museum, and hope to get help on all sides, and shall be particularly glad 

 to see specimens in the less studied groups. At present I have finished 

 the N. American Phytophaga, and hope to work at the Staphylinid^e ere 

 long. I also want to see all the Dytiscidae that I can, as it is only by a 

 long series that much can be done. I rhall be glad to hear from any one 

 interested in exotic insects, also. Yours truly, 



G. R. Crotch. 



larva of p. brevicauda. 



We extract the following from a letter recently received from Mr. 

 Edwards : — Miss Peart has drawn the larva of brevicauda. It differs from 

 asterias larva in that the black transverse bands are broken, and no yellow 

 spots are between them ; the lowest black spot is triangular, and so to 

 each band. It is more like zolicaon, although that has yellow spots. The 

 point is that it is not astei'ias.
