sinuate from near apex to posterior angles; anterior margin vaguely, trans- 

 versely sinuate, with an indistinct, median lobe ; base strongly, arcuately em- 

 arginate on each side, the median lobe strongly, broadly rounded ; disk uneven, 

 slightly convex, with a vague, longitudinal, median depression ; surface coarsely, 

 deeply, irregularly punctate, more densely, rugosely at sides, intervals feebly 

 granulose. 



E'ytra at base slightly wider than pronotum near apex, twice as long as 

 wide; sides parallel from humeral angles to apical third, then arcuately con- 

 verging to the tips, which are separately broadly rounded ; lateral margins 

 coarsely serrate; basal depressions broad and deep; humeral depressions broad 

 and shallow; surface glabrous, uneven, coarsely, deeply, irregularly punctate, 

 with numerous irregular, smooth spaces. Each elytron with a rather distinct 

 longitudinal costa along sutural margin becoming obsolete basally, the other 

 costae confused and indistinct, and with three large, slightly depressed, incon- 

 spicuous foveae, one at middle and two at apical third. 



Abdomen beneath sparsely, coarsely, irregularly punctate, sparsely, irregularly 

 clothed with short, semierect, white hairs, each sternite with a smooth, elevated 

 callosity on each side near lateral margin ; last visible sternite semicircularly 

 emarginate at apex, without a submarginal ridge, lateral margins serrate ; eighth 

 tergite broadly rounded at apex, coarsely, rather densely punctate, densely gran- 

 ulose, but not longitudinally carinate. Prosternum coarsely, confluently punc- 

 tate, rather densely clothed with long, erect, white hairs, with a distinct, rather 

 short, median lobe in front. Anterior femur with a short, rather acute, tri- 

 angular tooth, which is slightly dentate on outer margin. Anterior tibia strongly 

 arcuate, with a rather broad tooth at apical third ; middle and posterior tibiae 

 straight. 



Length 8 mm., width 3.25 mm. 



Figuke 28. — Anterior tibia of male (A), clypeus (B), and last visible abdominal 

 sternite of male (C) and of female (D) of Gliryso'botliris semisculpta. 



Redescribed from the male type of contigua. No. 2693, in the Museum, 

 of Comparative Zoology, Cambridge, Mass. 



Female. — Differing from the male in having the front of the head uniformly 

 cupreous and more sparsely pubescent, the antenna uniformly cupreous, the last 

 visible sternite more narrowly, arcuately emarginate at apex, the eighth ter- 

 gite densely, confluently punctate, and the anterior tibia unarmed.
