the proventrieulus with the diagonal teeth 

 feebly developed; episterna scaly. 



Scierus Lee. Page 73. 



HH Antennal club distinctly but not strongly com- 

 pressed, 1st segment much shorter than 2nd 

 and 3rd united. 



I Antennal club with first suture alone strongly 

 chitinized, distinct; each of first and second 

 segments longer than the third and fourth 

 united (PL 10, fig. 14) ; the proventrieulus with 

 a short diagonal band of small costal teeth 

 backwards from base of bristles, almost obso- 

 lete on disc which is not finely granulate; 

 ligula widened distally and truncate at tip; 

 the distance from the front of the eyes to base 

 of mandibles much greater than width of 

 eyes; antennal scrobes distinctly separated 

 from the front of the eyes; meso- and 

 metepisterna scaly. 



Hylastinus Bedel. Page 73. 



II Antennal club with first two sutures strongly 

 chitinized and distinct/ the two apical seg- 

 ments together longer than the second; the 

 disc of the proventrieulus finely granulate; 

 the ligula rounded at the tip; the distance 

 between the front of the eyes and base . of the 

 mandibles hardly greater than the width of 

 the eyes, which are narrow and elongate, 

 passing the base 'of the mandibles on the 

 ventral side of the head. 



J Segments of the club indistinctly subdivided 

 by a constriction and a row of hairs, third 

 and fourth segments very rapidly narrowed, 

 segments of funicle more strongly widened 

 distally (PL 10, fig. 2); meso- and met- 

 episternum scaly; 9th elytral interspace 

 strongly carinate; scutellum oblique.

JJ Segments of the club not so subdivided, third 

 and fourth segments longer, segments of 

 funicle not much widened distally; metepis- 

 ternum not scaly; scutellum not depressed, 

 (PL 10, fig. 1). '

FF Fore coxae narrowly separated; the disc of the proventri- 

 eulus with diagonal lines of teeth usually strongly 

 developed (PL 18, fig. 10). 



G Elytra with bases very strongly arcuate, slightly ele- 

 vated and finely evenly serrulate; 1st, 2nd, and 5th 

 ventral segments subequal in length (PL 9, fig. 25) ; 

 ligula wide, from a convex chitinized base, narrowed 

 distally; antennal hairs dense, stout and plumose; 

 the metasternum somewhat inflated, (PL 10, fig. 3).
