caplte opaco, crebre suLtiliter piinctulata, tliorace linea 

 media lajvi; an tennis pedibusquc obscure ferrugineis. 

 Long. Corp. fere 6 lin. 



Allied to S.Jimetaria, but veiy distinct by its smaller and 

 shorter head, Avhich is very differently punctured beneath. 

 The antennas are stout, much thickened towards the ex- 

 tremity, dark reddish, the basal joints pitchy ; 3rd joint 

 longer than 2nd ; 4 — 10 very short and broad, not differing 

 from one another in length, iOth nearly twice as wide as 

 the 4th; 11th joint short, stout and pointed, not oblique 

 at the extremity. Mandibles pitchy, very short ; palpi 

 yellowish. Head rather longer than broad, nearly straight 

 at the sides, but greatly roxmded at the back, about as 

 broad as the thorax; above quite dull, densely rugulose- 

 punctate, the punctuation at the back very fine, the 

 pubescence dense and rather long ; beneath closely punc- 

 tured at the sides, more sparingly and coarsely towards 

 the middle, the lateral grooves closely punctured, not deep, 

 and not separated from the part beneath by any distinct 

 smooth space. Thorax much narroAver than the elytra, 

 nearly twice as long as broad, slightly broader from the 

 base to in front of the middle, then narrowed to the front; 

 the sides are rather closely and not very finely punctured, 

 with an impunctate space along the middle, the oblique 

 impression not well marked, the pubescence rather dense. 

 The elytra are rather shorter than the thorax, moderately 

 finely and rather closely punctured, Avitli a rather long 

 pubescence; like the thorax, of a shining brassy-black 

 colour. Hind body closely and finely punctured, with a 

 dense soft pubescence. Legs pitchy red ; the tibia3 on the 

 inside with a grey pubescence. 



Obydos ; one specimen, probably a female. 



7. Sterculia minor, n. sp. Nigro-jenea, nitida, capite 

 opaco, thorace elytrisque crebre subtilissime punctulatis, 

 illo linea media la3vi; capite subtus crebrius punctato, 

 sulcis lateralibus nullis. Long. corp. 5^ lin. 



Closely allied to *S'. clavicornis, but with the head and 

 thorax rather broader, the punctuation of the thorax and 

 elytra much finer, and the head without any lateral 

 grooves. The antennas are rather stout, nearly black, the 

 extreme base of the 2nd joint red ; 3rd joint considerably 

 longer than the 2nd; 4—10 each a little stouter than the 

 preceding one, transverse, differing but little in length.
