354 FAMILY XI. — LYG>EID>£. 



margins of cultivated fields. In spring and summer taken by 

 sweeping weeds and grasses in meadows and waste places, all 

 stages having been found in Marion County as early as May 5. 

 In Florida it is very scarce, but has been taken by me at Dun- 

 edin, Sanford and Caxambus and is recorded by Barber from 

 Miami. Ranges from Ontario and New England west to Da- 

 kota, Colorado and British Columbia, and south and west to 

 Florida, Texas and California. The majority of the U. S. 

 records have been made under the name of A . angustatus Uhler 

 (1872, 406), a synonym. It often occurs in numbers sufficient 

 to cause much damage to field and garden crops. Riley (1873, 

 113) described it as N. destructor and gave it the common name 

 "false chinch-bug" by which it is usually known in the central 

 west. He recorded it as injurious to potatoes, turnips, beets, 

 radishes and cabbages ; also to strawberry and grape vines. In 

 some specimens the black of head and pronotum so predomi- 

 nates that the paler parts are scarcely visible, while in others, 

 especially the females, the hind lobe of pronotum is almost 

 wholly pale. Stal does not list the species in his Enumeratio 

 but mentions it under N. grcenlandicus. Milliken & Wadley 

 (1922) state that in Kansas N. erica- is extensively preyed upon 

 by a closely allied Lygseid, Gcocoris pattens decoratus Uhl. Parsh- 

 ley (1919, 15) records the appearance of criccc near Vernon, B. 

 C, in "great numbers, swarming over the trails and entering 

 houses. For a few days the walls of the houses, inside and 

 out, were covered with the insects, and complaints were made 

 that they bit children — altogether a most unusual occurrence."

 brownish-yellow; two short stripes on occiput, four vague ones on pro- 

 notum, extreme base of scutellum and a small spot on tip of corium, fus- 

 cous ; under surface dull yellow, the middle of all the sterna and the first 

 two ventrals blackish; antenna? reddish-brown, the second joint darker; 

 legs dull yellow, the femora with purplish-brown dots. Bucculae and beak 

 as in ericx. Head and pronotum closely and evenly punctate. Clavus 

 and corium finely, thickly and shallowly punctate. Expansion of costal

 3.5 mm. 



Miami, Fla., March 12 ; one specimen beaten from vegetation 

 on the grounds of the U. S. Entomological Station. A species of 

 western distribution, originally described from California. This 

 is the first record from east of the Mississippi, but Barber 

 (Ms.) says that he has seen it from Florida.
