226 CALIFORNIA ACADEMY OF SCIENCES. 



Bembidium jucundum n. sp. San Jose del Cabo, Si- 

 erra San Lazaro. 



Pristonychus complanatus Dej. More decidedly 

 black than the specimens from California. Probably in- 

 troduced through commerce. Europe, California. San 

 Jose del Cabo. 



EuPHORTicus PUBESCENS Dej. The unique example 

 is of the Central American type mentioned by Bates in 

 which the surface is decidedly brassy and the thorax 

 slightly broader with more arcuate sides. Occurs from 

 North Carolina southward through Mexico to Santa Cath- 

 arina, Brazil. San Jose del Cabo. 



Tetragonoderus pallidus Horn. San Diego, Cal., 

 Tucson, Ariz. Sierra El Taste. 



Tetragonoderus fasciatus Hald. Eastern United 

 States from Michigan southward, Texas, Arizona, south- 

 ern California. San Jose del Cabo. 



Apenes LUCIDUI.A Dej. The specimen referred to 

 this name is duller than usual and the surface sculpture 

 better marked. From the method of variation of the 

 species it seems unwise to describe the unique as a dis- 

 tinct species. There are no Mexican forms allied to it. 

 Eastern United States. Sierra San Lazaro. 



DYTISCID^E. 



Celina angustata Aube. Atlantic region and Flor- 

 ida to Texas. San Jose del Cabo. 



HYDROPHILID^.
