 were taken near Cape St. Lucas by Mr. John Xanthus. 



SALDID^. 



Salda interstitialis Say. Specimens were collect- 

 ed at Cape St. Lucas by Mr. John Xanthus. 



Salda pallipes Fab. One specimen is in the bottle 

 from San Jose del Cabo; and there are others in the col- 

 lection labeled "Cal. 2." 



Salda explanata Uhler. I have examined specimens 

 from Lower California, kindly sent to me by Mr. Henry 

 Edwards. In the collection there are a few specimens 

 labeled "Cal. 2." 



GALGULID^. 



Galgulus oculatus Fab. Numerous specimens have 

 been brought from Cape St. Lucas; and the insect is in 

 one of the bottles from San Jose del Cabo, collected by 

 Dr. Gustav Eisen. This insect inhabits nearly the whole 

 continent of North America. How such a clumsy and 

 merely leaping insect could become distributed so gen- 

 erally, beyond mountain ranges and at various altitudes, 

 from the tropics to the Laurentian hills, is a mystery not 

 easy to solve. 



Galgulus variegatus Guerin. A few species of this 

 silver-spangled form are included with the others from 

 Lower California. This does not seem to me as a good 

 species. It is more clearly marked and a cleaner insect 

 than the other, but there are varieties which very nearly 

 connect the extremes of color and marking. 



MoNONYX STYGicus Say. One specimen was taken 

 near Cape St. Lucas by Mr. John Xanthus; others were 

 secured at San Jose del Cabo by Dr. Gustav Eisen, also 

 at El Paraiso. On the eastern side of the continent its
