Two males from Madagascar, three females from Zanzibar. 



This is probably near C. filicornis (No. 1129), and may possibly be C. marginicollis, Boh. (No. 

 1280).— D. S.

" Ovatus, postice late dilatatus, ad apicem oblique rotundatus, convexiusculus, nitidus, supra nigro-piceus, 

 infra ferruginous ; labro, epistomo, thoracis lateribus vittaque longitudinali, simiilici, in elytrorum

This species I should think is allied to Dytisous atratus (No. 1100), but it appears to be paler be- 

 neath. — D. S.

" Niger, capita integi-o convexo, thorace sub lente subtilissime punctate, marginibus exterioribus flaves- 

 • entibus ; elytiis nigris flavo-marginatis, disco binis lineis punctorum hand fortiter impresso ; corpore infra 

 nigro nitido, pedibus quatuor anticis flavo-ornatis, posticis atro-piceis. Long. lin. 8, lat. lin. 4^." 



This is probably a Homseodytes near Dytiscus atratus (No. 1100). — D. S.

" Mas etfemina : thorace elytrisque liievibus. Long. 33-35 m.w. (15-1 6 lig.) lat. 1 7-18^ m.m. (8-8-| lig.) 



" Ovalis, postice dilatatus, ad apicem subrotundatus, minus convexus, nitidus ; supra nigro- viridis infra 

 testaceohiteus ; palpis, antennis, mandibulis, labro, epistomo, thoracis lateribus, vittaque longitudinali 

 apice subhamato-dilatato elytrorum latera versus, testaceis ; pedibus testaceis, tibiis intermediis posticisque 

 f uscescentibus. "

" La femelle entierement lisse comme le male, sur le corselet et les elytres, n'en diifere que par une 

 plus grande dilatation du corps, au dela du milieu." 



" Des eaux de Jourdain." 



" Cette espece resemble, pour la coloration, au mas du Cyb. roeseUi, mais sa forme est pluu allong^e 

 et moins elliptique." 



It is doubtful whether this be a distinct species from D. rceselii, (vide Nos. 11 GO and 1170). — D. S.
