Hemiptera-heteroptera. 



All of the following species were determined by Dr. P. L. R. Uhler : — 

 Lioderma ligata, Stal. 



In coitu on mesquite (P. julifloi-a), July 14. It was found numerous 

 on Chinese cabbage on college farm July 16. 

 Mozena obtusa, Uhler MS. 



Taken in July on Prosopis juliflora. In coitu July 8. 

 Chelinidea v it tiger a, Uhl. 



Taken in coitu May 24 on a small fruit of Opuntia, Soledad Canon. 

 Hadronema militaris., Uhl, 



Swept from alfalfa May 1 2. 

 Nenrocolpus nubihis, Say. 



This capsid was beaten extensively from flowers and foliage of mes- 

 quite (P. Juliflora) May 10. May 12 to 16 both adults and larv?e were 

 beaten. The adults vary from a light yellowish or greenish to brown and 

 almost black, usually more or less mottled. They doubtless grow darker 

 with age. The larvae are of a clear, light green colour. 

 Calocoris sziperbus, Uhler. 



This capsid is numerous on alfalfa, both adults and larvae, and doubt- 

 less causes considerable injury to the plant. May 8 to 12 both stages 

 were found in abundance. May 28 the adults were numerous, and a few 

 nymphs were found. The adult is blackish, with orange or yellow on the 

 sides. The larvse and nymphs are green, with the extremity of the body 

 brown. Predaceous heteroptera and lady-birds were also swept, which 

 doubtless prey upon the capsid. 

 Calocoris sp. ? 



Beaten from scrub oak (Quercus undulatus var. Wright ii) in Soledad 

 Canon May 24. It is very pale yellowish, with faint brownish markings. 

 Oak determined by Mr. \V. H. Evans. 

 Lygus pratensis, Lin. var. 



Adults and larvae swept from alfalfa May 12. Only adults swept 

 May 28. The adults vary from light green or glassy to a uniform light 

 and dark brown, and one specimen has only the posterior portions 

 brown. The larvae are green with black dots on the thorax, and one 

 black dot in the middle of the first abdorninal segment. This species is 

 also, I believe, injurious to the alfalfa.
