some new Species of Sagra, Sfc, 253 



Female. — Intermediate thighs produced beneath into an obtuse 

 tooth ; hinder pair armed on the lower edge with a stout acute 

 sub-apical tooth, hinder tibias arcuate, their inner surface tuber- 

 culate at the base, the apex simple. In tliis sex there are indi- 

 cations of some deeply punctured striae on the elytra ; they are, 

 however, much interrupted by the rugosities of the surface, and 

 are with difficulty to be made out. 



Hab. White Nile. Both sexes in my own cabinet. 



Very close to S. tristis, immediately after which insect it must 

 be placed ; it differs in the broader thorax, the much more 

 strongly marked rugosities on the surface of the elytra, and in the 

 different shape of the posterior femora ; these latter are much 

 longer, scarcely increasing in thickness from below their base 

 nearly to the apex, their upper edge being much straighter and 

 obsoletely sinuate in the middle. 



Sagra Dohrnii, n. sp. 



Elongate- oblonga, laete purpurea, nitida ; antennis corporis 

 dimidio paullo longioribus ; thorace sub-quadrato, margine 

 antico modice producto, angulis anticis sat productis, re- 

 trorsum fere curvatis, margine antico arcuatis, elytris fortiter 

 vermiculatis, interspatiis (praesertim ante medium) valde ele- 

 vatis, plicato-rugosis. 



Fcem. — Femoribus intermediis subtus acute unidentatis, posticis 

 subtus denticulatis, ante apicem crista brevi antice unidentata 

 instructis ; tibiis ejusdem paris arcuatis, apice vix mucronatis, 

 processu prosternali compresso, retrorsum producto. 



Long. 8 lin. 



Narrowly oblong, bright purple, nitidous. Head finely punctured, 

 front impressed with a quadrilobate fovea; antennae robust, rather 

 longer than half the body. Thorax sub-quadrate, apical margin 

 moderately produced, anterior angles very prominent, their front 

 edge convex, the hinder one concave, causing the angles them- 

 selves to appear almost recurved ; upper surface shining, impunc- 

 tate, impressed near the base with a shallow fovea. Elytra rather 

 more parallel and less narrowed behind than in Sagra Murrayi, 

 otherwise agreeing in form and sculpture with that species, their 

 surface still more irregular, the punctate striae more deeply im- 

 pressed, coarse, and rather more visible to the eye. 



Female. — Intermediate thighs armed beneath with an acute 

 tooth ; posterior pair not exceeding the elytra in length, their 

 lower edge denticulate, produced before the apex into a short
