the proventriculus 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 Antenna,l club with first suture alone strongly 

 chitinized, distinct; each of first and second 

 segments longer than the third and fourth 

 united (PI. 10, fig. 14) ; the proventriculus 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- 

 nients together longer than the second; the 

 disc of the proventriculus 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 (PI. 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, 

 (PI. 10, fig. 1).

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

 culus with diagonal lines of teeth usually strongly 

 developed (PI. 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, (PI. 10, fig. 3).
