The following notes relate to various insects: 



Dione vanillce. 

 Some years ago I took a brightly-coloured form of this butterfly at 

 San Diego, California. As it was obviously different from the insect of 

 our Southern States, I took occasion to look it up in the British museum. 

 I found that the Californian insect was the true vanillce, as found in 

 Mexico and the West Indies ; while the darker and somewhat differently 

 marked insect familiar in the United States is a very good sub-species, to 

 which the x^zxsxt passiflorce, Abb.-Sm., is applicable. 



Hemileuca sororia, Hy. Edw. 

 I recently saw the type of this in the American Museum of Natural 

 History. It is remarkably large and dark, with roseate hind wings. I do 

 not think the New Mexico insect (olivice) is conspecific. 



Lasioptera ephedrce, Ckll. 

 Dr. D. T. MacDougal showed me galls of this species on Ephedra 

 trifurca, which he collected on the sand dunes at San Felipe Bay, Lower 

 California. 



Lecaiiium capefise, Walker. 

 The type in the British Museum shows that this is a Diaspid. I do 

 not recognize the species, but it resembles a Pseudaonidia. 



Orthezia Americana, Walker. 

 Tne type is missing from the British Museum, and a note where it 

 should be states that it has been missing since Aug. 1874. Under these 

 circumstances it will be quite imi)Ossible to recognize the species. 

 Pogonoviyrviex occidentalism Cresson. 

 Going west I first noticed the nests of this ant at Ruleton, Kansas. 

 They probably are as indicative of the beginning of the arid region as any- 

 ^ thing one could mention,
