ha)mn, from which it is separated by the epipleiirse being dilated 

 beneath the humeri and the superior margin distinctly visible from 

 above, there forming the sharp arcuate margin of the rounded humeri. 

 A Humboldt County specimen is similar, but less strongly develojDed. 



General ohseri^ations. — The mentum, pro- and mesosternum, are 

 as in parvicoUis. 



The metasternum laterally between the coxa? is as long as the width 

 of a mesotibia at the middle. 



The abdominal process is subquadrate and a third (male) to a 

 fourth (female) of its width broader than the metasternal salient. 



In the male the post-coxal part of the first abdominal segment is 

 equal in length to that of the process, also to that of the third ; the 

 second is one-half longer than the fourth. 



In the female the second segment is equal in length to the j^rocess; 

 the third to the post-coxal part of the first and a third longer than the 

 fourth. 



The tarsi are varial)le in thickness, but moderate in length. Usually 

 more slender in the male.

ELEODES PARVICOLLIS var. PRODUCTA Mannerheim. 



Distinctly oblong to oblong-ovate, thorax transverse; eh^tra de- 

 pressed, sides jDarallel, humeri j^rominent and obtusely romided. 



Head twice as wide as long, feebly convex, slightly impressed 

 laterally and along the frontal suture, the latter more or less obsolete, 

 densely, evenly, or irregularly and somewhat coarsely punctate, i)unc- 

 tures denser laterally. Ajitouia^ somewhat long, stout, very feebly 

 compressed and scai'cely dilated in outer four joints, tliird joint about 

 as long as the next two combined, fourth just the least longer and 

 stouter than the fifth, the latter to the eighth, inclusive, equal in 

 length, the eighth not noticeably wider than the preceding two, ninth 

 triangulo-oval, tenth feebly transversely oval,. tenth ovate. 



Pronotum transversely oblong-oval, widest at the middle, a half 

 to three-fifths wider than long; disc moderately convex, feebly im- 

 pressed laterally so as to appear somewhat dilated, rather coarsely 

 and somewhat densely punctate, denser and somewhat finely granu- 

 late laterally on the impressed area ; ajyex more or less feebly and 

 broadl}'^ emarginate, more or less obsoletely beaded; side^ broadly 

 and quite strongly arcuate to basal eighth, thence constricto-sinuate 

 to the angles, at times quite abruptly and tubularly constricted, with 

 sides parallel to the angle, bead thin and reflexed, a mere line on the 

 basal construction ; base truncate or very feebly rounded, and usually
