238 University of California PuUications. [Entomology 



nigrita, much narrowed anteriorly, where it is a little wider than the 

 base of the vertex; surface convex in both diameters, strongly punctured; 

 callosities large, highly polished, impunctate, scarcely elevated and poorly 

 defined; sides nearly straight or slightly concave. Scutellum more finely 

 punctured. Elytra coarsely punctured, long, narrowed from the middle. 

 Membrane long and narrow, nervure dividing the areoles obsolete or 

 nearly so. Prosternal xyplius depressed with a carinate margin. Basal 

 joint of hind tarsi stouter, as long as second and third together. Arolia 

 as in Camptobrocltis, wanting or very minute and connate with the claws, 

 between which are two slender parallel setae. Male uncus formed about 

 as in CamptohrocJiis nitens with a sharp curved hook at distal end wliich 

 almost attains the line of the proximal extremity. 



Color a uniform deep coal-black, brilliant; membrane a dead blackish- 

 fuscous, scarcely lighter next the point of the cuueus; base of vertex and 

 knees touched with fulvous. Second antennal joint nearly to its apex 

 and the tarsi piceous, verging toward castaneous. Osteolar margin white. 



Described from nine examples representing both sexes, all 

 beaten from Jeffrey pines along the south slope of ]\Iount Tallac 

 above Glen Alpine Creek during late July. This is one of our 

 largest capsids, and it seems strange that it should have remained 

 unlaiown for so long unless it be restricted to the Jeffrey pine, 

 which has a range in the Sierras and northwardly where little 

 work on Hemiptera has been done. Dr. Poppius has recently 

 sunk Camptohrochis as a s^aionym of Deraeocoris, but I think 

 it better to restrict the latter genus to those species having a 

 clavate second antennal joint. 



Deraeocoris fraternus, new s]iecies 



This form seems to differ from iiigciis principally in being smaller 

 (6 mm.) and in having the basal one-half of the second antennal joint 

 and the legs pale or even bright rufus, with the apex of the tibiae darker 

 and the tarsi black. Generally there is a pale auuulus beyond the middle 

 of the tibiae and the margins of the pleural j)ieces are whitish, usually 

 broadly so. 



Described from ten examples representing both sexes taken 

 with the preceding. I would consider this but a color variety of 

 iiujfiis were it not for its much smaller size and the constancy 

 of its characters. 



Largidea grossa, new species 



Form nearly that of marginata, but larger; dull rufus-brown, whole 

 upper surface closely and coarsely punctured. Length to tip of membrane 

 6 mm.
