than those here described, one of which has long been in my collection, without locality, 
and was supposed by me, from its facies, to belong to the East-Indian region. 
1. Misantlius optatus. (Tab. X. fig. 2.) 
Flavo-ferrugineus ; capite, thorace antennisque (basi excepta) nigricantibus ; abdomine fuscescente, basi rufes- 
cente, apice late testaceo; opacus, elytris flavo-pubescentibus. 
Long. 15 millim. 
Hab. Mexico (Flohr), Misantla (Hége). 
Head very densely punctate, quite dull, with red mandibles and palpi. Thorax very 
opaque, narrowed behind, densely and quite obsoletely punctate, very dull. Elytra rather 
longer than the thorax, densely punctate, clothed with a short golden pubescence. 
Hind body rather closely punctate, the three basal segments each with a short longi- 
tudinal plica at the base on each side, about halfway between the side and the middle, 
and extending less than half the length of the segment. 
The male has a small emargination on the apical ventral segment, and the front feet 
are rather broader than in the female; the example figured is of the latter sex, and 
was found by Hége at Misantla. Mr. Flohr’s example was sent me some years ago, 
without any specified locality. 
2. Misantlius torquatus. 
Ferrugineus ; capite, thorace, antennisque nigricantibus; abdomine apicem versus nigro-fusco, stylis analibus 
rufescentibus, apicibus fuscis; mandibulis palpisque piceis; opacus, elytris minus lete flavescenti- 
pubescentibus. 
Long. 17 millim. 
Hab. Guatemaa, Calderas (Champion). 
Mandibles (of male) very elongate, beyond the middle abruptly attenuate and much 
twisted. Head very broad, very densely punctate. Thorax very obsoletely punctate. 
Hind body densely punctate ; the three basal segments dark dull red, the three following 
blackish, the apical one (which is sparingly punctate) with metallic reflections; on each 
side of the three basal segments the plicule are connected together at the base by a 
deep transverse impression. Hind tarsi very elongate. 
Though very similar to VV. optatus this unique individual is distinguished by numerous 
good characters. It is a male, and has a distinct notch on the terminal ventral plate. 
3, Misantlius carinulatus. (Tab. X. fig. 3.) 
Ferrugineo-obscurus ; capite nigro; antennis abdomineque nigricantibus; hoc basi rufescente, subnitido, parce 
punctato ; capite, thorace elytrisque opacis, his dorso ad latera carinulato-marginato, 
Long. 15 millim. (mandibulis clausis). 
Hab. Mexico (Flohr), Toxpam (Sa/l/é). 
This is readily distinguished from the other two species by the colour of the thorax,
