HEMIPTERA OF LOWER CALIFORNIA. 23 1 



it has been able to hold its own in the province of Quebec, 

 as readily as on the torrid sands of the region of Cape 

 St. Lucas. It is almost everywhere to be found on the 

 American continent where weeds can grow and low 

 plants can secure a hold in the soil. 



Thyanta rugulosa Say. Several specimens of this 

 small form were secured at Cape St. Lucas by Mr. John 

 Xanthus. It seems to be local, as it has not been reported 

 from many localities in California which are similar to 

 others from which it has been taken. 



Thyanta casta Stal. This species is common in Mex- 

 ico, California, Arizona and New Mexico. It was taken 

 at San Jose del Cabo by Dr. Gustav Eisen, and likewise 

 from the vicinity of Cape St. Lucas by Mr. John Xan- 

 thus. 



Thyanta pallido-virens Stal. This is a Mexican 

 insect, which was collected at Cape St. Lucas by Mr. John 

 Xanthus. 



Chlorocoris depressus Fab. One specimen was se- 

 cured at San Jose del Cabo by Dr. Gustav Eisen. 



Chlorocoris rufispinus Stal. Afew specimens were 

 collected near Cape St. Lucas by Mr. John Xanthus. 



MuRGANTiA HisTRioNiCA Hahn. This extremelv com- 

 mon insect has spread into vegetable gardens, and maybe 

 expected to occur on most parts of the peninsula where 

 man has settled. I have examined specimens from Cape 

 St. Lucas, San Jose del Cabo, the island of Santa Cruz, 

 of Guadaloupe, etc., and from many parts of Central 

 America, Mexico, California, and from the western and 

 southern States generally. 



Nezara viridula Linn. This ubiquitous species 

 occurs likewise at Cape St. Lucas, San Jose del Cabo, 

 and on the islands of Santa Cruz and Guadaloupe.
