2. Monista similis. 
Ferrugineo-brunnea ; antennis brevibus, nigricantibus, apice testaceo ; palpis, pedibus elytrorumque apice flavis ; 
capite prothoraceque dense fortiter punctatis. 
Long. 34 millim. 
Hab. Guatemata, Zapote, La Tinta (Champion). 
This insect is very similar to M/. concolor, but besides being smaller than the smallest 
variety of that species, it has also the elytra considerably shorter and distinctly flavescent 
at the hind margin. It is equally close to the Brazilian WZ. typica, but has stouter and 
darker antenne and a more densely punctured thorax. We have received only one 
example from each locality ; in one of them the antenne are darker than they are in 
the other, possibly the result of decay. 
3. Monista plagiata. 
Ferruginea, antennis fuscis, basi et articulo ultimo, palpis pedibusque testaceis ; elytris apice vage testaceo, ad 
latus plaga magna nigricante. 
Long. 33 millim. 
Hab. Panama, David, Volcan de Chiriqui 3000 to 4000 feet (Champion). 
Antenne with the two or three basal and one or two apical joints yellow, the rest 
dark. Head rather small, rounded behind, rather sparingly punctured. Thorax rather 
small, about as long as broad, globose, rather sparingly punctate, with a broad line 
along the middle impunctate. Elytra much longer than the thorax, very obsoletely 
punctate, the apex yellow, a large dark mark, rather indefinite, on the side of each, 
fading away towards the suture. Hind body testaceous. 
The place of this species is between MM. typica and M. longula. We have received a 
series of nine examples from David, and one from the Volcan de Chiriqui; this latter 
may possibly, however, prove to be a different species, as it differs in several of the 
minuter details. 
4, Monista strigicollis. 
Brevis, fusco-ferruginea, antennis, palpis, pedibus, elytrorum abdominisque apicibus testaceis ; capite posterius 
truncato-emarginato, cumque prothorace fortiter strigoso-punctatis. 
Long. 3 millim. 
Hab. Panama, David (Champion). 
Antenne yellow, immaculate, short and rather stout, the joints from the fourth to the 
tenth each broader than long. Head subquadrate, not narrowed or rounded behind, 
the vertex a little emarginate ; the surface reticulately sculptured, almost as in the genus 
Sunius. Thorax transversely subglobose, rather coarsely, strigosely sculptured. Elytra 
longer than the thorax, densely and distinctly punctured, the apex broadly though 
rather indefinitely yellow. Legs short. 
Of this distinct species only one example was obtained.
