43. SiLPHOMORPHA Froggatti, n.sp. 



Black, nitid, of almost the same proportional dimensions as S. 

 striatipennis, the head more transverse, the thorax quite smooth 

 with the margins piceous, and the elytra very finely striated with a 

 row of minute slightly distant punctures on each sti*ia and the 

 interstices flat and smooth. The under surface and legs are 

 piceous. 



Long. 6 lines, lat. 2| lines. 



44. SiLPHOMORPHA LATICOLLIS, n.Sp. 



Black, nitid, proportionally broader than S. Froggatti, and in 

 other respects very similar. The elytra are more nitid and the 

 punctate strise are very tine and apparently most distinct near the 

 apex. 



Long. 5J lines, lat. 3 lines. 



45. SiLPHOMORPHA OBSOLETA, n.Sp. 



Very like the last-named species in general character. Black, 

 sub-nitid, minutely punctate all over ; the punctate strise of the 

 elytra nearly obsolete, the lateral margins broader and of a piceous 

 hue. 



Long. 6J, lat. 3 lines. 



46. SiLPHOMORPHA PUNCTATISSIMA, n.Sp. 



Black, nitid, of broadly ovate form ; head smooth, thorax of the 

 usual form, very minutely punctate, the apex less eraarginate than 

 in the other species, with the lateral margins smaller, the base 

 truncate and the posterior angles less rounded. The elytra are 

 rounded a little on the sides, and are wider a little than the
