112 FAMILY V. — PENTATOMID^E. 



face densely, rugosely irregularly punctate, the elytra more finely and 

 evenly so; thoracic pleura rather coarsely irregularly punctate; abdo- 

 men finely aciculate-punctate, the middle third almost smooth. Head 

 wider across the eyes than long, its apex broadly rounded. Other struc- 

 tural characters as given under generic heading. Length, 11 — 15 mm.; 

 width, 7.5—8.5 mm. (Fig. 23). 



Pine and Millers, Lake Co., Ind., July 5 — Oct. 16; taken on 

 juniper (Gerhard). Long Island, New York and Victoria, Van- 

 couver's Island (Davis). Ranges from Quebec and New Eng- 

 land across the northern United States to British Columbia 

 and Alaska, and south in the western portion to California and 

 Old Mexico, Stal's type being from the latter country. Hart 

 (1919, 183) states that: 



"It is exceedingly abundant in the Illinois Valley sand regions, swarm- 

 ing on the dwarf prickly-pear cactus, Opuntia rafinesquii, and feeding 

 mostly at the tip of the fruits when these are present. I have also taken 

 it in the sand dunes of the Chicago area on dwarf cedar, Juniperus sa- 

 bina L. The dates are April 1 — Nov. 17. Nymphs occurred June 6 — 

 Oct. 30. In the late fall most adults are a dark brownish carmine re- 

 sembling that of the ripe fruit of the Opuntia on which they occur." 



Vestal (1913, 29) says that "This is the characteristic Pen- 

 tatomid of the sands in Illinois. It is a plant feeder and the 

 adults pass the winter in sheltered places. In April they have 

 been taken crawling about on the sand and also under cactus 

 lobes and boards. It is a typical bunch-grass species." About 

 Buffalo, N. Y., Van Duzee (1894, 171), found it "occasional on 

 various trees and bushes, especially willows and junipers, May 

 to October." 



C. ulilcri has been mentioned or treated by the authors of this 

 country under several different names, chief of which are Pcn- 

 tatoma juniperina Linn., a European species, and Chlorochroa pcr- 

 similis Horv., a synonym of uhleri.
