None of these belong to the true coast fauna, and with the 

 exception of subangulata none have occurred west of the 

 Sierras.

Further collecting is almost sure to add to the lists of almost 

 any of the above western localities, but little or no increase 

 can be expected in the Atlantic district. Thirty-four species 

 are given in the "Biologia" as inhabiting Mexico and Central 

 America, but this is surely only a fraction of the species oc- 

 curring there. Whether any of the species described from our 

 southwestern region are identical with the Mexican ones is 

 not possible to say with certainty, but the probability is not 

 very great. 



In concluding these preliminary remarks I wish to thank- 

 fully acknowledge the very ready and generous response from 

 all correspondents to requests for specimens or information. 

 The very large material of the National Museum and Horn 

 collections have been loaned for study, and there has also 

 been placed in my hands the material contained in most 

 of the larger private collections of this country, viz. : that 

 of Messrs. Blanchard, Bowditch, Leng, Beyer, Schaeffer, 

 Liebeck, Dury, Wickham, Knaus, Fenyes, Blaisdell and Van 

 Dyke. Finally, to Mr. Samuel Henshaw I am under renewed 

 obligations for permission to study the LeConte types at the 

 Cambridge Museum, without which anything like satisfactory 

 progress would have been impossible.
