tico latiusculo prosterni dense fortiter punctato. Abdomen 

 subtus laeve, latera versus subtilissime punctulatum. Fe- 

 mora omnia subtus prope apicem utrinque spina armata, 

 antica fortiter incrassata, prope basin in latere exteriore in 

 tuberculum (a supero visum distinctissimum ) prominentia; 

 articulus primus tarsorum posticorum ceteris unitis minus 

 quam duplo longior. (Forma macroptera ignota.) Long. 

 (^ 6,5 mm. (Mus. Stockholm.) 



Njoro. 



A ver}^ distinct species, remarkable by t lie strueture of 

 the pronotum, whicli is very similar in shape to that of many 

 Garabidae, and by having all femora armed with spines. 



In his generic description of Scantius Distant (Rhynch. 

 Brit. Ind. II, p. 117) says: »anterior femora spined beneath 

 near apices», but that the Indian S. obscurus Dist. (1. c, 

 p. 118) has all femora spined is clear from the figure of it which 

 he published låter (Libr. cit. V, p. 98). In its other charac- 

 ters S. caraboides is, however, quite distinct from obscurus. 



13. Dysdercus cardinalis Gerst. 



Guaso Nyiro. 



In his key to the African species of Dysdercus Schouteden 

 (Rev. Zool. Afr. I, p. 303 — 305) has omitted D. antennatus 

 Dist. from Guinea.
