New Species of Lopidea from Arizona (Hemip. 



Miridae).* 

 By HARRY H. KNIGHT, Ithaca, New York. 



( Plate X.) 



The writer did considerable collecting in Arizona, while 

 with the Cornell Biological Expedition, and in the present 

 paper gives the results of his studies on the species of Lopidea 

 taken in that region. This interesting genus presents a num- 

 ber of species having great similarity of coloration and gen- 

 eral form but with very distinct genital structures, characters 

 which must be used if we are to determine the species con- 

 sistently. 

 Lopidea arizonae new species (Plate X, Fig. 1). 



Suggestive of marginata but much larger and with bright 

 red on the basal half of the pronotum : genital claspers dis- 

 tinctive of the species. 



$ . Length 7 mm., width 2.3 mm. Head white, the sutures, sides 

 of tylus, heavy bar each side of the median line of the front and the 

 base of the head black; rostrum blackish with pale on the first seg- 

 ment, eyes brownish to black ; antennae black, second segment linear. 

 Pronotum with the basal half bright red, shining, narrow basal margin 

 fuscous, anterior margin white, calli black. Scutellum fuscous, pale 

 median stripe on the apical half. Hemelytra dark red shaded with 

 fuscous, more red bordering the embolium and on the inner half of 

 the cuneus ; embolium and outer margin of the cuneus ivory white ; 

 fine pale pubescence with short black bristles on the white embolium ; 

 membrane fuscous. Coxae and femora more or less pale and marked 

 with fuscous and black ; femora fuscous on the front margin with a 

 row of black dots beneath and usually two rows on the upper side, 

 tibiae and tarsi black. Venter marked transversely with alternating 

 bands of fuscous, reddish and pale. 



9 . Very similar to the male in coloration, only more robust, the 

 pale color more extended on the venter. 



This species was taken by the writer on Robinia ncomc.vi- 

 cana in Post Creek canyon near Bonita, Arizona. It occurs 

 apparently in several mountain ranges of Arizona at altitudes 

 of 6000 to 7500 feet.
