446 PROCEEDINGS OF THE NATIONAL MUSEUM vol. m 



Pronotum: Length about half width, 0.78:1.62; anterior margin 

 moderately singly emarginate ; lateral margin slightly converging from 

 base, more strongly rounded anteriorly, with submarginal row of five 

 setigerous punctures; transverse impression obsolete, absent medially, 

 not marked by a row of special punctures; anterior lobe, except for 

 most of calli and oblique strip in anterior angles, with a broad band of 

 punctures anteriorly, laterally and posteriorly; calli with a few minute 

 punctures; transverse impression, posterior lobe and extreme hind 

 margin with a mixture of coarse and fine punctures. 



Scutellum: Length-width ratio, 1.20:0.88; shining, surface, except 

 basal angles, with irregularly scattered moderate and fine punctures 

 intermLxed and becoming finer and more uniform toward apex. 



Hemelytron: Polished, clavus with one complete and one partial 

 row of punctures; mesocorium with numerous well-separated punc- 

 tures, the discal ones, like those in the two rows paralleling the claval 

 suture, becoming coarser toward base; exocorium with fewer and finer 

 punctures than mesocorium; costa thin, slightly reflexed, with a 

 single subbasal setigerous puncture dorsally; membranal suture feebly 

 sinuate, lateral angles not projecting; membrane about as long as 

 basal width, just reaching tip of abdomen. 



Propleuron: Anterior convexity, except dorsally and posteriorly, 

 with numerous net-like rugae; fewer punctures in the depression; 

 prosternal carinae about as high as labial II, gradually terminated 

 posteriorly. 



Mesopleuron: Evaporatorium reachmg almost to posterolateral 

 angle; with few punctures anteriorly. 



Metapleuron: Terminal modification of peritreme moderate, ex- 

 tending about two-thu-ds of way across supporting plate; lateral area 

 with a few moderate to fine punctures near lateral margin of evapora- 

 torium, 



Sternites: Polished, punctuate and/or horizontally rugose laterally. 



Length of body: 3.19. 



Type data. — Signoret gave the locality of the type as "Sitka." 

 This agrees with the specimen in the Signoret Collection which also 

 bears the name "Kolenati." This must be the type female (Wien). 



Discussion. — ^Examination of type specimen made possible the 

 recognition of this species, which the author at first considered to be 

 a synonym of subglaber. The elongate form does suggest that it is 

 close to subglaber but the lack of a strong transverse impression and the 

 two sizes of punctures on the posterior pronotal lobe and site of the 

 transverse impression will separate the two. Signoret's illustration in 

 his monograph is misleading in not showing the calli as being polished 

 with only a patch of minute punctures medially and in indicating the
