PUPA OF ELEODES CLAVICORNIS. 

 (Plate 13, figs. 1, 2, and 3.) 



Length, 10.5 mm.; Avidth of body, 4.5 mm.; greatest width from 

 knee to knee, T nnn. C)l)l()ng-oval, moderately arcuate, head flexed 

 against the prosternum ; abdomen moderately depressed ; color yellow- 

 ish white, appendages semitranslucent. 



Head exposed, vertex visible from above, clypeal region convex, 

 frons somewhat transversely impressed, vertex rather more promi- 

 nent ; antennae curving backward against the sides of the prothorax, 

 over the profemora, at which point they are not visible when viewed 

 from below. 



Pronotuni evenly convex ; base almost truncate, basal angles rather 

 broadly rounded, sides arcuate, apex feebly and broadly emarginate, 

 with angles somewhat narroAvly rounded. 



Mesonotum short., transverse, and moderately convex; elytral j)ads 

 passing obliquely backward and ventrally above the pro- and meso- 

 crura, apical fourth between the meso- and metacrura, visible ven- 

 trally only at this point. Ej:)ipleural margins apically contiguous to 

 basal half of the mesotarsi. 



Mctanotuiii a little longer than the mesonotum, moderately convex, 

 and broadly sinuate behind, 



LegH prominent laterally, not appressed against body, distinctly 

 compressed and comparatively broad; tarsi distant from each other 

 in median line, except the metatarsi, which are in contact in apical 

 half; coxa? and sterna visible in the median line. 



Ahdoniinal segments convex dorsally, less so ventrally; pleural 

 region of segments one to seven produced laterally into subquadrate 

 laminiform processes; last two segments without lateral processes 

 and more evenly convex from side to side. Fourth ventral segment 

 deeply and broadly emarginate at apex; fifth smaller, rather arcuate 

 at apex and within the emargination of the fourth: third segment 

 broadly and less deeply emarginate. 



Abdomen at apex terminating in two elongate processes, each grad- 

 ually tapering from base to apex, the latter chitinous; beneath the 

 bases of these cerci there is a small segment which is deeply emar- 

 ginate, with angles j^rominent j)osteriorly. 



The lateral processes of segments one to seA'en are limited at base 

 dorsally by a longitudinal impression on either side of the dorsum; 

 the impression begins on segment one and ends on base of the seventh; 

 ventrally the imjiressions are less strongly marked. 



In the sjiecimen at hand the processes of segments two to six are 

 deeply and semicircularly cnuirginate at middle thii'd. each anterior 

 and posterior third is sfiuarely truncate at apex, with angles sub- 

 acute, those at the emargination are chitinous and denticulate, each
