than abdomen, with membrane reduced to a mere border to apex 

 of corinm. Legs short, tibiae and some minute dots on apex of 

 femora green. 



Dextral hook of male genitalia small, nearly circular at apex ; 

 sinistral subtriangular, its inner angle produced in a short tooth. 

 the outer prolonged in an incurved subacute horn. 



Color pale bluish-green, becoming yellowish on head, pronotum 

 before, and on lower surface. Antennae pale, scarcely darker 

 at apex. Sides of pectus and abdomen more or less greeni.sh, 

 perhaps wholly green in life. Tibiae pale, with minute pale hairs 

 and a few longer brownish bristles. Elytral costa paler; mem- 

 brane whitish, with a very faint apical clouding, nervures green. 



The types of this species were from Colorado, and I found it 

 common at Denver, Boulder, Ward, and Sunset, Colorado, in 

 July, 1903. The female has been determined for me as Labopidca 

 chloriza Uhler, but it wants the black markings mentioned in 

 Uhler's description, and for the present I prefer to consider 

 chloriza as a species unknown to me. 



Labopidea atriseta n. sp. 



Closely allied to sericata Uhler, but distinguishable by having 

 infuscated antennae, and tibiae armed with conspicuous black 

 bristles set on black dots, while in sericata these bristles are 

 weaker and fewer and are not inserted in black points. Color as 

 in the preceding form. Length 5 mm. to tip of membrane. 



Head as in sericata, vertex feebly cariuate at base ; front con- 

 vex, clypeus prominent. Antennae a little longer than in allied 

 species; second joint about three times as long as basal; third, 

 three-fourths the length of second, the fourth short. Rostrum 

 a little shorter than in sericata, scarcely attaining apex of inter- 

 mediate coxae. Elytra with membrane developed in all my speci- 

 mens, apex of cuneus attaining tip of abdomen. 



Color a soiled whitish, more or less tinged with dull green 

 below ; disk of pronotum and scutellum and the elytra dull bluish- 

 green, costal margin broadly pale; cuneus pale except its inner 

 angle. iMembrane obviously infuscated, with a deeper shade out- 

 wardly beyond the areoles. Antennae infuscated, basal joint pale. 

 Hind femora distinctly dotted with greenish-brown exteriorly, 

 tibiae armed with stout black bristles much longer than the width 

 of the joint, each springing from a black point. Tarsi and tip 

 of rostrum black. 



Described from four females taken by me at Alpine, ^lussey 's, 

 and Sweetwater Valley, San Diego County, California, in April 

 and June.
