The head is ferruginous, convex, subquadrate, with scattered punctures ; the ocelli are very 

 lai'ge, especially the four upper ones, and together with the sides of the head are of a 

 deep black ; the antennae are ferruginous, pubescent, with forty-one joints : the labium 

 is broad, flattened, punctured and hairy, with the dental border nearly straight, and 

 armed with eighteen minute black teeth, of which one or more of the external ones are 

 often absent ; the body is polished, with a black longitudinal fascia, often more or less 

 indistinct. Mandibles, labium and legs yellow, the five posterior legs blackened or 

 annulated ; metatarsal joints very hairy, ferruginous ; claws black ; articular spines of 

 all the legs very short, excepting one on the tarsus, which is much elongated. 



This is a fine species, collected by Mr. Hope both at Florence and Naples. 

 It approaches very much in its appearance to L. varlegatus, but is a great 

 deal larger. 



The specimens obtained from Naples are usually of a much lighter colour, 

 but in other respects they agree precisely with those from Florence.
