204 HISTERIDA. 
27. Hister servus. | 
ister servus, Er. in Klug’s Jahrb. der Ins. 1834, p. 1477; Mars. Monogr. in Ann. Soc. Ent. Fr. 
1854, p. 561, t. 9. fig. 126”. 
Hab. Mexico, Playa Vicente, Tuxtla (Sallé), Esperanza, Oaxaca, Tula in Hidalgo, 
Jalapa (Hoge); Guatemata, Chacoj in Vera Paz (Champion); Panama, Taboga Isl. 
(Champion).—ANTILLES, Cuba! 2, San Domingo 2. 
Some of the examples in this collection differ from the type in being larger, the 
propygidium with a larger grade of punctures, and the outer thoracic stria varying in 
length, being either short or complete. One of the series from Tula has no sutural 
stria to the elytra; the name of comes is provisionally given to it, as it seems almost 
certain that it is distinct from Z. servus, Er. 
28. Hister castaneus. 
Mister castaneus, Lewis, Ann. & Mag. Nat. Hist. 5th ser. xv. p. 4657. 
Hab. Nicaragua, Chontales (Belt !),—Cotompia, Santa Marta. 
I have seen a nearly black example of this species from Santa Marta, so that it seems 
probable that the specimens captured by Mr. Belt are immature. H. castaneus is easily 
known from H. servus, Mars., by the finer and more sparse. punctuation of the propy- 
gidium and pygidium. 
29. Hister criticus. 
Mister criticus, Mars. Monogr. in Ann. Soc. Ent. Fr. 1861, Pe 551, t. 14. fig. 417. 
Hab. Mexico}, Cordova (Sallé, Hége), Cholula in Puebla (Hége). 
EPIERUS. 
Epierus, Erichson in Klug’s Jahrb. der Ins. 1834, p. 158. 
About sixty species of this genus have been described; three are recorded from 
Southern Europe and a few from Asia, but by far the greater number are from the 
New World, more especially from within the tropics. Some of its members possess 
remarkable sexual characters, such as tubercles on the head and excrescences on the 
thorax, but in the majority of the known forms these qualities are wanting. The 
species are found beneath the bark of trees. 
1. Epierus frontalis, (Tab. V. figg. 15; 15a, profile.) 
Epierus frontalis, Kirsch, Berl. ent. Zeitschr. 1866, p. 173"; Mars. Ann. Soc. Ent. Belg. xiii. 
1870, p. 91”. 
Hab. GuatEMALaA, Tamahu and Cubilguitz in Vera Paz (Champion); Nicaragua, 
Chontales (Janson).—Cotomsia, Bogota ! 2. : 
Seven examples. The female of this species has no frontal tubercle.
