1. Xylocoris umbrinus, new species 

 Allied to cursitans Fallen, but proportionately broader as 

 in discalis Van D.; deep polished black, antennae rostrum, 

 corium and tibiae brown or piceous. Length 3 mm. 



Head a little shorter and broader than in sordidus, about as long 

 as wide including the eyes, polished. Antennal seg. I scarcely attaining 

 apex of head; III and IV equal, each but little shorter than II. Rostrum 

 long, apparently nearly attaining intermediate coxae. Pronotum as in discalis, 

 hiehly polished, the lobes scarcely distinguished, the posterior minutely acicu- 

 late, not transversely impressed; sides straight, rounded to anterior angles, 

 obtusely carinate, this carina reaching to middle of collum. Scute Hum nearly 

 flat, highly polished, feebly rugose posteriorly. Elytra uniformly P? llshe d> 

 behind the fracture narrower than abdomen ; costa feebly arcuate behind the 

 middle of corium, surface with scattering minute pale hairs. Ostiolar canal 

 shorter than in discalis and the sordidus group of species bent toward, but 

 not quite attaining, the anterior margin of the metapleura, the angle rounded, 

 apex subacute. Hind tibiae pale-pubescent, without longer soft hairs. _ 



Color deep shining black, basal two antennal segments and femora piceous- 

 black- apical two segments of antennae, rostrum and tibiae pale piceous or 

 brownish ; elytra piceous-brown, clavus, or at least its inner margin, and the 

 cuneus darker; membrane hyaline-white. 



Described from one male taken by me at Bryson, Monte-

 under the bark of an old fir log near Cayton, Shasta Co., 

 Calif., July 14, 1918.
