Vol.1] Van Duzee. — Lake TaJwe Hemiptera 239 



Head impunctate, jiolished, clothed with sparse, short appressed pale 

 pubescence; viewed from above short, transverse, gently swollen before; 

 width about twice its greatest length; when viewed from before five- 

 angled, portion above the antennae almost quadrangular with sides 

 straight and parallel, apex obtuse; base of clypeus but feebly dis- 

 tinguished from the front. Rostrum attaining the base of the inter- 

 mediate coxae. Antennae as in marginata, inserted near lower angle of 

 eye; basal joint scarcely longer than the eye; second joint is as long as 

 vertex and pronotum taken together, flattened horizontally and broadly 

 lanceolate, its width equal to length of first joint, its lower surface 

 feebly convex, the upper deeply sulcate nearly to the apex; third and 

 fourth thin, fusiform, each subequal to the first in length. Pronotum 

 broader and less narrowed anteriorly than in marginata, sides straight, 

 distinctly carinate, attaining the middle of the eyes; posterior lobe 

 deeply closely punctured; anterior lobe nearly smooth, gray-pubescent, 

 transverse impressed line deep, black, bent back in a barb at either 

 side of the median line. Scutellum strongly convex, closely but not 

 deeply punctured. Elytra closely punctured, the eosta bent beyond the 

 middle. Cuneus long, but moderately depressed. Membrane long, sur- 

 passing the abdomen by one-half its length. Basal joint of the tarsi 

 broad and flattened, scooped out below, wider than the apex of the tibiae 

 and as long as slender third joint; second short, slender like third, deeply 

 inserted in upper surface of broad first joint. Oviduct beginning before 

 middle of venter. 



Color dull rufus-brown inclining to wine-red but not as deej) a red as 

 in the allied marginata. Whole surface closely but not conspicuously 

 pale-pubescent; disk of head and much of lower surface blackish; costa 

 l)aler; membrane black, nervures black at base, paler beyond. Antennae 

 reddish. Tarsi and venter blackish. 



Described from a single female example taken on Jeffrey pine 

 on the south slope of ]\ronnt Tallae near Glen Alpine Springs, 

 July 30, at an altitude of about 7000 feet. It is possible that 

 the expanded basal joint of the tarsi and the fact that the secoutl 

 antennal joint is scooped out above instead of below would entitle 

 this form to generic distinction, but it does not seem advisable 

 to separate it until the male has been examined. In the type 

 specimen the thickened apex of the second antennal joint is 

 somewhat bent, making the antennae appear to be five- jointed 

 when viewed from the side. 



Dacerla infiata Uhler. This singular looking ant-mimic was 

 quite abundant after the middle of July at most all locations but 

 especially along the southern slope of ]\Iount Tallae. A few 

 were seen above 8000 feet on Angora Ridge. It was most abun- 

 dant on the lodge-pole pine, but it occurred on other trees and
