390 Mr. E. Newman on the Genus Passandra, 



dinal marginal furrow which originates near the base of the 

 antenna and passes above the eye ; anteriorly the head has 

 three deep impressions, of which the middle one occupies the 

 clypeus, and the lateral ones are nearly approximate to it, 

 but rather further back towards the crown of the head. The 

 prothorax has a posterior and marginal lateral ridge which is 

 produced on each side the head ; dorsally, rather behind the 

 middle, it had two obscure impressions. Each elytron has three 

 longitudinal furrows ; the 1st is deep, near the suture, origin- 

 ating by the side of the scutellum and extending to the apex ; 

 the second also deep, originating dorsally near the shoulder, 

 but ceasing considerably before the apex ; the third is vague 

 and shallow, originating laterally considerably below the 

 shoulder, passing round the termination of the second and 

 ceasing near the apex. 



Inhabits Sierra Leone. A single specimen obligingly lent me for 

 description is in the cabinet of the Rev. F. W. Hope. A very 

 lengthened, minute and accurate description of this insect by Dalman 

 will be found in the Appendix to Schonherr's Synonymia Insec- 

 torum, p. 146.

Pitchy black, shining, with an obscure longitudinal stripe of 

 red on each elytron. The head has a deep transverse furrow 

 nearly parallel to the anterior margin of the prothorax ; at each 

 posterior angle of the head this is joined by a longitudinal mar- 

 ginal furrow, which originates near the mandibles, curves out- 

 wards to the base of the antenna, and passes ab6ve the eye ; 

 anteriorly the head has one deep impression occupying the 

 clypeus, and on each side of this a vague and diffuse linear 

 impression extends from each mandible to the great transverse 

 furrow. The prothorax has a posterior and lateral marginal 

 ridge which is acutely produced on each side of the head ; 

 dorsally it has two abbreviated furrows, originating almost 

 close to the anterior margin and ceasing at about two thirds of 

 the entire length of the prothorax ; these furrows are very 

 distant and considerably nearer the lateral margins than the
