])arte posteriore elevata, anteriorc alnujitc decliva ; al)- 

 domine subtus magis pimctato. Long, corp. 6 lin. 



Antennas short and stout, 1^ lin. in length; the 10th 

 joint hardly so long as broad. Mandibles short and stout, 

 their up])cr edge strongly sinuate near the base. Head 

 Avith the longitudinal channel as deep in front as behind ; 

 the hind ])art of the clypeus elevated to tlie level of the 

 vertex, and on the same ])lane with it, but quite distinctly 

 marked out therefrom, the front part of the clypeus at 

 right angles to the hind portion ; the upper part of the 

 head is black, with the neck obscurely reddish, beneath 

 blackish-red. Thorax rather broad, red, 1 line in length, 

 and quite 1^ in breadth. Elytra narrower than tlie thoi'ax, 

 1 \ lin. in length, and just about the same in breadth, quite 

 black. Hind l)ody black, moderately stout ; on the under 

 face, the segments 3 — 6 are coarsely punctured over a 

 large space on each side the middle. Legs black, Avith the 

 tarsi reddish. 



Ega ; a single individual, of the male sex. 



Obs. — This species is closely allied to both L. brunnco- 

 vigcr and L. viaxillosiis. The structure of the head and 

 mandibles is almost the same as in the former species, but 

 />. latro is smaller and has the thorax shorter, and the 

 elytra black. The sti'ucture of the head distinguishes the 

 species from L. maxillosus, and the shorter antennte dis- 

 tinguish it from both the species alluded to.

Ega; St. Paulo, about a dozen examples. 



I find great difliculty about this species ; indeed, it 

 seems to me probable that two or three variable and yet 

 closely-allied species may be confounded in collections 

 under this name. JNL Fauvel has separated one form and 

 given it the name of L. prafeus, but I have not been able 

 to satisfy myself as to which of the forms his description 

 refers. This author gives a figure of the front of the head 

 of an insect he calls X. maxillosus (Notices Ent. pt. ii. 

 pi. i. fig. 2), but 1 have seen no specimen at all like his 

 figure. 



These Amazonian individuals vary much in size, colour, 

 and also somewhat in the front of the head ; but as I 

 cannot see that these characters indicate distinct species, 

 I think it best merely to record them as L. maxillosus.
