HEMIPTERA OF LOWER CALIFORNIA. 2^5 



lion was kindly sent to me from Los Angeles by Mr. D.W. 

 Coquillett. 



Neurocolpus nubilus Say. Syn. jV. mcxicanus Dist 

 One specimen was taken at Cape St. Lucas by Mr. 

 John Xanthus. A single specimen in the collection of 

 the California Academy of Sciences is marked "Cal. 9." 



This species is one of the most variable of the incon- 

 stant Phytocoraria. It is distributed all over the North 

 American continent from Quebec to Panama, and it seems 

 to be about as variable in Mexico as it is in Maine or 

 Maryland. As I have compared specimens with Mr. 

 Distant's types, I find them to be precisely like varieties 

 of N. nubilus Say, which I have collected with my own 

 hands, and some of which I have raised from the newly 

 excluded condition to the fully matured state. A per- 

 manent variety has the posterior femora dark gray, with 

 a small pale spot on the upper side. The other extreme 

 of color has the hind femora yellowish or fulvous, with 

 the apex broadly black. The basal joint of the antennae 

 is also variable in thickness. In some specimens the tip 

 of this joint is knobbed and smooth. 



Calocoris superbus Uhler. 



This common species occurs near Cape St. Lucas, as 

 well as in Mexico and the western United States. 



Calocoris rubrinerve Dist. This is a common spe- 

 cies in Mexico, southern Florida, Texas and the Lesser 

 Antilles.- Specimens were found at Lower Purisima in 

 April, and on Margarita Island in March, by Mr. CD. 

 Haines. 



Calocoris vigens n. sp. 



Clear green, opaque, more robust than C . rubrinerve, 

 minutely pubescent. Head greenish-yellow, almost ver- 

 tical in front, the eyes moderately prominent, dark brown.
