GARDEN FLEA-HOPPER IX ALFALFA. 3 



P. R. Uliler (o)^ recorded the garden flea-hopper as having been 

 found at the experiment station at Logan, Utah, which point has 

 an approximate altitude of 4,700 feet above sea level. 



SYNONYMY. 



- The garden flea-hopper was first named and described by Ash- 

 mead (1) as Khinocloa citri. E. A. Popenoe (2) in 1890 called it 

 " Halticus minutus Uhler MS." During the same year Giard (3) re- 

 named the species uhleri, since there was already a Halticus minutus 

 Renter. Distant (4, p. 430) in 1893 redescribed the species as Calo- 

 coris canus, not recognizing its true affinities. 



Reuter (12) in 1909 first pointed out that Rhinocloa citri Ashmead 

 and Halticus uhleri Giard were the same, but he left the species un- 

 der the latter name until 1914, when H. G. Barber {15) used the 

 combination '^Halticus citri (Ashm.)" in print. 



The synonymy, therefore, is as follows: 



Halticus citri (Ashmead) Barber. 



Rhinocloa citri Ashmead (Z). 



Halticus minutus (Uhler MS) Popenoe {2). 



Halticus uhleri Giard {3). 



Calocoris canus Distant (4). 



Halticus citri Barber (15). 



fflSTORY OF THE SPECIES AND ITS INJURIES. 



Halticus citri seems first to have received economic mention in 1887, 

 by W. H. Ashmead (/), who found it on orange trees in Florida. 



In 1892 A. Giard (3) recorded it as being destructive to peanut and 

 rice crops of French Cochin China and Singapore, Straits Settlements. 



This species, with Agalliastes bractatus Say, was reported from 

 Kansas in 1890 (2) as follows: 



We have the past season observed two species of Capsidse, or plant-bugs, living in 

 great numbers on the undei'side of the leaves of the garden bean, puncturing the 

 tissues and sucking the sap, and by these jninctures causing the death of the tissues 

 in small, irregular patches, that appear iqion the upper surface of the leaf as white 

 spots. 



It was found by J. B. Smith (6', p. 133) in New Jersey during 1900 

 injuring truck crops at the following places: New Brunswick, James- 

 burg, Swcdesboro, Madison, Camden County, and A'ineland. 



In 1900 F. M. Webster (7) reported it from Wooster, Ohio. F. H. 

 Chittenden (<S') states: 



In May and June, 1900, tliis insect was observed in some numbers on beans in dif- 

 ferent localities, and some leaves were found to have been killed by its attacks. 

 Beets and cabbage were also affected, Imt injury was loss noticeable to these crops. 

 In 1001 the writer noticed severe injur\- to ornamental morning-glory in the city of 

 Washington.
