This peculiar species in which the elytra are ornaraented by a 

 testaceous-yellow discoidal vitta, curved to"wards the shoulder 

 riear the base, straight in its central portion and curved again, 

 slightly towards the suture (near the apex), resembles so closely 

 A. lineatus Wollaston, from the Cape Verde Islands that it can 

 scarcely be considered as more than a local variation. The form, 

 colours and sculpture areexactly the same, withthe exception that 

 the sides of the thorax are perceptibly more rounded behind the 

 middleandthe antennaearewholly reddish instead of blackish with 

 the 3 basai joints only red. I bave examples of A. mttatiis from 

 Angola, and others of^. vittaMis from Bombay. The distribution of 

 the species is paralleled by that of TrecMcJiusJimicola Woll. which 

 is also found in the Cape Verde Islands (and Madeira) and is met 

 with again (under slight modifications) over great part of South- 

 Eastern Asia. 



Subfamily STENOLOPHIN^. 



Stenolophus crenulatus Dej., Sp. Gen., IV, p. 432(?). 



Four examples agreeing so closely with Dejean's description 

 that I think they may be safely referred to it. The strong sculp- 

 ture is a highly peculiar feature for a StenolopJms. Dejean did not 

 know the locality of bis spécimen. 



Subfamily PTEROSTICHIN^. 



Abacetus cyclodes n. sp. 



A. guttulse (Chaud.) aji%is et simillimus, sed differt thorace 

 distincte latiori^ lateribus icsque ad angnlos posticos rotundiorihus 

 nec sinuatis, angulis j^osticis dentimilo excepta, ohtusis ; ante7inis 

 omoiino rufis. — Long. 6-6 i/a millim. 



Closely allied to A . guttula and having a similar red, posterior 

 elytral spot on interstices 4-7 or 4-8 (smaller on 6-8 especially 

 on 6), but a larger insect, with somewhat more broadly rounded 

 thorax, the sides showing no trace of sinuation before the hind 

 angles which would be obtuse if it were not for a dentiforra pro- 

 jection at the angle. The base of the thorax is broader, but is 

 strongly though scantily punctured in the middle as in J. qnttiila. 

 The antenu8e differ in being uniformly testaceous-red (like the 

 legs) and not fuscous with the three basai joints only red as in 

 A. guttula. I bave seen several examples of both species which 

 are constant in their points of différence ; but A. cyclodes does not 

 offer the variety, which seems in fact,to be the more fréquent form 

 of A. guttala in which the elytra hâve a subhumeral as well as 

 subapical spot.
