parte posteriore elevata, aiiteriore abrupte decliva ; ab- 

 domine subtus magis puuctato. Long. corp. 6 lin. 



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

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

 their upper edge strongly sinuate near the base. Head 

 Avith the longitudinal channel as deep in front as behind ; 

 the hind part of the clypeus eleyated to the level of the 

 yertex, and on the same plane "svith 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 the thorax, 

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

 black. Hind body black, modei'ately stout ; on the under 

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

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

 tarsi reddish. 



Ega ; a single individual, of the male sex. 



Ohs. — This species is closely allied to both L. brvnneo- 

 viger and L. maxillosus. The structure of the head and 

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

 L. latro is smaller and has the thorax shorter, and the 

 elytra black. The structure of the head distinguishes the 

 species from L. inaxUlosus, and the shorter antenufe dis- 

 tinguish it from both the species alluded to. 



4. L. maxillosus (Fab.). 



Ega ; St. Paulo, about a dozen examples. 



I find great difficulty about this species ; indeed, it 

 seems to me probable that two or three variable and vet 

 closely-allied species may be confounded in collections 

 under this name. ]\L Fauvel has separated one form and 

 given it the name of L. jrroteus, but I have not been al)le 

 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 L. maxillosus (Notices Ent. pt. ii. 

 ])1. i. fig. 2), but I 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.
