shorter in tlie middle than at the sides, its length at tlie 

 former point being abont eqnal to that of 3 or 4. Legs 

 ratlier short and stout ; tibiae with a sharp mucro, tlie 

 corbels o£ the hind pair open and bare; the claws connate. 



All the specimens examined appear to be females. 



Genotype, Slrophosomus (jranicoUis, Bolr. 



Thank's to the kindness of Pruf. E. 13. Ponlton, F.R.S., 

 I have been able to examine the cotypes of S. (jranicoUis, 

 Boh., in the Sommer collection, which he recently presented 

 to the Oxford Musenm. 



From the description, it seems fairly certain that Strojiho- 

 somiis verrucicollis, Fst. (Ann. Soc. Ent. Belg. 1899, p. 390), 

 from the Congo, also belongs to this genus. 



The angnlate elytra and tuberculate thorax would at once 

 distinguish these insects from the other African " Strophu- 

 su)iius," and they have more the appearance of very small 

 Bluftynis, which may however be distinguished by the very 

 different structure of the epistome and lower surface of the 

 rostrum, the more prominent eyes, and the straight hind 

 raai'gin of the first ventral segnjcnt. 



Ketj to the Species. 



1 (6). Prolhorax with small, close, confluent tuber- 



cles tbroujjhout. 



2 (3). Tiie two median furrows on tlie rostrum 



subparallel ; the two basal joints of the 

 fuuicle equal; punctures on elytra more or 

 less irrftgular r/ranuo//is, Boh. 



3 (2). U'he two median farrows on the rostrum 



strongly divergent in front; joint 1 of the 

 funicle longer than 2. 



4 (5). Elytra marginate at the base, the rows of 



punctures more or less irregular or dupli- 

 cated sicalei, sp. n. 



■5 (4). Elytra not marginate at the base, the rows of 



punctures quite regular rec/ularis, sp. n. 



6 (1). Protbiirax punctate on the disk and tuber- 

 culate laterally verrucicollia, I'st. 



Bradybamon swalei, sp. n. (PI. I. fig. 6.) 



$. Colour piceous, with dense earth-brown scaling; 

 pronotum with a broad, median, darker brown stripe, which 

 gradually widens from apex to base; elytra with an ill- 

 defined dark stripe running obliquely from behind the 

 shoulder to beyond the middle of stria 2 and edged behind 

 with an indefinite pale stripe ; the apical area with irregular 

 dark brown and paler patches ; these markings may become 

 more or less obsolete.
