 {liihottiy Mus. Genoa) (c. m.). 



I have pleasure in dedicating this species to Dr. U. Gestro, 

 who has most indulgently j)laeed at my disposal the wealth 

 of the rich collection of t!ie Civic Museum of Genoa, including 

 numerous types of de Bornians and Borelli. 



The Genoa Museum contains two females, which I provi- 

 sionally and with hesitation referred to S. tripunclata, lior. ; 

 but an examination of the type of that species and further 

 material receivetl, including two males, shows that it is quite 

 distinct from that species, but very closely allied to L./ete^ 

 Dubr. In coloration and structure it approaches L. fe<e very 

 closely, but it is a little larger, the antennal segments more 

 cylindrical, the fourth a little shorter, the pronotum les.s 

 strongly transverse ; the colour less deep black aud more 

 reddish, the feet differently coloured, the points of the 

 pygidium less sharp, the foreejts less arcuate, much stouter, 

 especially in the apical half; finally, L. fcce is a Pa[)uan, 

 S. (jestroi a West-African species.

 had come from South America instead of Africa, I should
