of Floscularia, now sent me by Mr. Pilate, has the antennae pec- 

 tinate. Two specimens of Glomeraria have the wings much 

 darker, and an inner band on primaries not noticeable in my type. 

 Three specimens of Septemfluaria have only the three ochre lines 

 on fore wings and two on hind wings visible. The external line 

 and blotches are obsolete. — AUG. R. Grote. 



Fans on the Forelegs of Catoc. Fraxini. In the En- 

 tomologists' Annual for 1871, p. 75, Dr. Knaggs writes: " Catoc- 

 ala Fraxini has visited the Regent's Park, and this reminds me 

 that the sight I had of this specimen (alive) taught me something 

 of which I was previously entirely ignorant, viz.: that the crea- 

 ture is endowed, for some inscrutable reason, with large fans 

 (or rather in this particular instance with a large fan) on its fore- 

 legs, after the fashion of some Geovietridce and PyralidcB." I 

 may add that the structures are very common among the NoctiicB 

 QuadrifidcB, though they are frequently retracted, and therefore 

 liable to escape observation. Lepidopterists believe them to be 

 organs connected with the production of a peculiar odor, differ- 

 ing possibly in each species. Tufts of hair, probably homolo- 

 gous in function, occur on the antennae, or at the base or ex- 

 tremity of the abdomen, of many Lepidoptera, but the present 

 subject is one that has only recently attracted the attention of 

 Entomologists. — W. F. Kirby. British Museum.
