SOME NEW GENERA AND SPECIES OF PHYTOPHAGOUS COLEOPTERA 



COLLECTED DURING CAPTAIN BOTTEGo's LAST EXPEDITION 



BY MARTIN JACOBY 



Dr. Gestro submitted to me the rest of the Phytophaga ob- 

 tained by the late Capt. Bottego on his last expedition in the 

 Somali-Land and Upper Sobat , amongst which I found several 

 apparently new genera and species as well as others previously 

 described by Chapuis and myself. A single female specimen of 

 Sagra Slevensi, Baly was also obtained , this sex was not pre- 

 viously known , but on comparison with the male type in the 

 British Museum I have not much doubt about the identity of 

 this specimen with that of Baly's which was obtained at the 

 White Nile region. 



1. Sagra Stevensi, Baly. — g. Dark purplish blue, opaque, 

 the lower five joints of the antennae shining, thorax slightly 

 broader than long, impunctate, the anterior angles prominent, 

 produced laterally, elytra subgeminate punctate-striate slightly 

 depressed below the base, the interstices finely wrinkled here 

 and there, the posterior femora strongly dilated below the middle, 

 the apical portion finely crenulate below, their tibiae curved , 

 simple, the intermediate femora not much widened. 



Hah. Da Sancurar agli Amarr Burgi. A single specimen. 



How Baly could have described the colour of this species as 

 metallic green 1 cannot understand, the type is a dark purplish 

 blue identical with the specimen obtained by Capt. Bottego ; the 

 principal character of distinction in this species consists of the 

 produced or acute anterior angles of the thorax and the short 

 ridge of the upper edge of the posterior femora in the malo 

 which is absent in the other sex.
