biseriate subcostal area and clearly marked moniliform costal 

 area, which is continued about the apex of the elytra, will dis- 

 tinguish this species.

Our California species of Teleonemia may be distinguished 

 by the following key : 



Subcostal area biseriate 1 



Subcostal area uniseriate 2 



1. Subcostal area conspicuously biseriate; pronotal carinse conspicuous; 



large brown species nionile, new species 



-. Subcostal area narrow, Obscurely biseriate ; pronotal carinas incon- 

 spicuous; smaller cinereous species schwarzi Drake. 



2. Antennae stouter; third segment about twice the length of the 



fourth ; costal area conspicuously areolate ; color fuscous varied 



with cinereous nigrina Champ. 



-. Antennae more slender ; third segment nearly three times the length 

 of fourth ; costal area very narrow, obscurely areolate ; color 

 brown, nearly uniform, with the head black. . .z/Jdwa, new species 



10. Oncerometopus calif ornicus, new species 



Larger and darker than nigriclavus ; sanguineous, antennae, 

 legs, callosities, clavus, inner field of corium, membrane and 

 genital segment black; disk of pronotum more or less infus- 

 cated either side of the pale median line. Length to tip of 

 membrane 63^ mm. 



Vertex and tylus rather more convex than in nigriclavus. Antennae with 

 the second segment distinctly longer than in nigriclavus , a little longer than 

 the pronotum ; third and fourth together a fourth shorter than second, in 

 nigriclavus nearly a fourth longer. Pronotum proportionately longer, its 

 length two fifths its basal width, in nigriclavus scarcely more than one 

 half; sides nearly rectilinear, a little expanded at the humeral angles; col- 

 lum as long as the thickness of first antennal segment; callosities prominent, 

 distinguished by a deep incision which is especially distinct behind the 

 median bridge connecting them anteriorly. In nigriclavus this incised line 

 is not conspicuous and behind the median bridge is represented by two 

 impressed punctures ; surface transversely rugose with scattering shallow 

 punctures and an obvious obtuse median carina ; hind margin almost trun- 

 cate. Elytra nearly parallel, a little expanded at the middle, the embolium 

 narrowly linear, distinct; surface polished, distinctly uniformly shagreened, 

 in nigriclavus more opaque and but obscurely shagreened. Apex of abdo- 

 men in both sexes reaching midway between the tip of the cuneus and that 

 of the membrane. Tibiae short-setose. Tarsi ; basal segment scarcely ex- 

 panded, second a little shorter than median length of first, in nigriclavus 

 hardly half that length. Male genital characters rather obscure, the dextral 

 hook lunate, a little narrowed posteriorly and lying against the excavated 

 margfin of the segment.
