S. postiealis, sp. n. 



Testacea, pedibus concoloribus, antennis (basi excepto) nigris; 

 clongata, griseo-pubescens, pronoto transverso, baud dense punc- 

 tate, angulis anticis paulo prodnctis, posticis acutis, baud productis ; 

 elytris panim elongatis, humeris modice prominentibus ; antennis 

 gracilibus, articulis omnibus elongatis, ultimo quam latiori dimidio 

 longiori : 



(^, tibiis posticis arcuatis, postice paulo dilatatis. 



Long. 3-5 mm. ; lat. 2 mm. • 



Tonkin : Hoabinh {R. Vitalis de Salvaza, Aug.). 



I have seen only a single male specimen of this insect, 

 vmich resembles S. tibialis, but the antennae are black, 

 with the exception of the two basal joints, the anterior 

 angles of the pronotum are a little produced and rather 

 broadly margined, and the elytra are a little less oval and 

 convex. The antennae of the male are still more slender 

 than in that sex of S. tibialis, all the joints being distinctly 

 elongate, but the terminal joint is shorter and only half as 

 long again as it is wide. The hind tibia in the same sex 

 is curved and a little dilated posteriorly, instead of the front 

 and middle tibiae, as in S. tibialis (Fig. 6). 



S. crassieornis, sp. n. 



Rafo-testacea, antennis (basi excepto) nigris; elongato-ovalis, 

 griseo-pubescens, pronoto transverso, convexo, minute sat crebre 

 punctato, angulis posticis acutis, baud productis ; elytrorum humeris 

 parum prominentibus; antennis crassis, baud brevibus, articulo 

 basali ovali, inflato, tertio et ultimo paulo elongatis, ceteris brevibus, 

 8-10 transversis : 



^, antennis crassioribus, planatis, tibiis anticis intus (basi 

 excepto) fortiter deplanatis, tortis, margine interno apice valde 

 reflexo, tibiis intermediis pone basin arcuatis. 



Long. 3-5 mm. ; lat. 2 mm. 



Philippine Is., Bukidnon, Tangcolan (6*. F, Baker). 



Prof. Baker has sent a single specimen of each sex. 



The whole of the legs and the two basal joints of the 

 antenna are of the same pale colour as the body, the 

 remaining part of the antenna alone being black. The 

 general form differs little from that of S. curvipes, but 

 the pronotum is rather more convex. The antennae are 

 very distinctive. They are rather stout and long, with the 

 first, third and last joints only distinctly elongate, and
