64 ENTOMOLOGICAL SOCIETY 



Mr. Howard exhibited specimens of Proticerya rileyi 

 Cockerell, from New Mexico, on mesquite, and also a curious 

 new Coccid collected by Messrs. Townsend and Cockerell, at 

 Apache Agency, New Mexico, on Gutieriza. This insect Mr. 

 Cockerell proposes to call Crypticerya toiunsendi, making 

 Crypticerya a new sub-genus. The speaker called attention to 

 some points of difference between this form and true Icerya and 

 particularly the large genital orifice which is exactly in the mid 

 dle of the body, and said that in his opinion it would form a new 

 genus instead of a subgenus. 



A paper by Mr. Cockerell entitled " Miscellaneous Notes" 

 was read by the Secretary. 



MISCELLANEOUS NOTES. 

 By T. D. A. COCKERELL. 



The following notes are suggested by Proc. Ent. Soc. Wash., 

 IV, No. i, just to hand : 



(i) Mr. Schwarz's notes on semi-tropical Texas interest me 

 very much. I wish Mr. Ashmead would give us some informa 

 tion about the bees of that region. The bee-fauna of southern 

 New Mexico is highly peculiar, with a very large percentage of 

 new species, though it extends somewhat northward along the 

 eastern side of the Rocky Mountains, and also westward and 

 southward in the arid region of Mexico and Arizona. It is 

 characterized by apparently peculiar genera, Protandrena and 

 Phileremulus, and an enormous development of Perdita. 

 There are very few Osmia, or Prosopis, or Nomada. All this 

 contrasts strongly with the mountain region of Colorado, whence 

 Cresson described so many bees. Here Perdita vanishes, and 

 Prosopis becomes abundant, with plenty of Osmia, Nomada, 

 &c. Lately I have examined a collection made by Prof. Town- 

 send in Vera Cruz State, in the tierra caliente. It is totally dif 

 ferent from the arid-region fauna, and resembles in part that of 

 the eastern and southern U. S., and in part that of South Amer 

 ica. There is not a single Perdita. Augochlora, rare in the 

 arid region, is abundantly represented. Megachile presents 

 many forms ; Ceratina has developed a very beautiful species. 

 Now what relation has the bee-fauna of semi-tropical Texas to 

 these ? It is an interesting question. 



Mr. Schwarz refers also to the insect fauna of the mesquite 

 not being uniform throughout the range of the plant. The in-
