DESCRIPTIONS OF NEW GENERA AND SPECIES OF 



PHYTOPHAGOUS COLEOPTEBA FROM 



AFEICA AND MADAGASCAR. 



Bv JIARTIN JACOBV. F.E.S. 



ALTHOUGH, as far as our knowledge extends iit ])resent, Africa is not 

 ])articnlarly ridi in Ph/topliayous Coleoptfia. scarcely a collection is received 

 from that country which does not contain some interesting new genera 

 and species, and it is highly ])robal)le that if an experienced collector were ahle 

 to examine the interior portion of that vast continent as carefully as has been 

 done in many other parts of the world no end of interesting new forms would turn up. 

 Certain it is, that those species already known have in the majority of cases a wide 

 distribution in difterent parts of Africa, and this is again confirmed by the exami- 

 nation of the present collection submitted to me by Mr. Rothschild. I have for 

 the present not given all the names of already well-known species, but confined 

 myself to the descriptions of those which are new or little known. To these I have 

 added a few from my own collection and from the neighbouring island of 

 Madagascar. 



The types of the species not marked "coll. Jacol)y " are in Mr. Hothschild's 

 Museum. 



Sagra striatipennis sj). nov. 



Elongate, bluish black, head and thorax impunctate, elytra very deejjly and 

 regularly jiunctate-striate at the anterior portion, nearly impunctate at the ajiex. 



(J. The intermediate femora broadly and triangularly toothed, the posterior 

 ones greatly protruding beyond the elytra, their base flavo-tomentose within, the 

 upper edge with an acnte ridge, the lower one with a stout tooth near the apex, 

 posterior tibiae regularly ctu-ved with a long sjjinc before tlie apex, the latter 

 broadly sulcate within. 



?. Thorax longer and narrower, elytral punctuation more feeble, intermediate 

 femora with a small tooth, jiosterior ones not extending beyond the elytra, their 

 upper edge simple, without ridge, their lower margin with a short row of teeth at 

 the base, of which the innermost one is more distinct, tibiae simple without tooth. 



Hub. Tauta (E. Africa). 



This species agrees in coloration with .s'. nmrrayi and <S. /«'ri/// Baly as well 

 as with several others. It is closely allied to either, also to S. tristis and S. hicolor 

 Lac, but differs from any in the deep rows of tlic elytral punctures which are 

 not at all approached in pairs, as in nearly all those mentioned above, also in 

 )S. longej'emorata Fairm. ; these deep rows of punctnres are well visible with the 

 naked eye but disappear, as is usual, below the middle, and the interstices are 

 rather convex and imi)unctate. The antennae are very long, tiie third and fourth 

 joints are equal, the four terminal joints are very elongate, they are entirely of 

 a dark bluish colour, the thorax is slightly longer than broad, the sides are straight 

 jind the anterior angles rounded and scarcely produced ; the posterior femora are
