ZOPHOBAS. 103 
This species may be known by its depressed and comparatively smooth upper surface 
and almost obsolete humeri; the elytra are much more finely punctate-striate than in 
the allied species ; the female has much the general facies of Alobates pennsylvanica, De 
Geer. A single male only of the var. ?, several of the type. 
ZOPHOBAS. 
Zophobas, Blanchard, Hist. des Ins. ii. p. 15 (1845); Lacord. Gen. Col. v. p. 876; Kraatz, 
Deutsch. ent. Zeit. xxiv. p. 121 (1880). 
Numerous species of Zophobas are known from Tropical America, the genus ranging 
from Mexico to Brazil and Peru; several species are found in the West-Indian Islands, 
and one has been described from the island of Puna; one or two species from Ceylon 
have been ascribed by Walker to the genus, but probably inerror. Dr. Kraatz (/oc. cit.) 
enumerates twenty-one species ; others, undescribed as yet and not included in this list, 
are known in collections. Ten, of which three appear to be undescribed, are now known 
from Central America. The different species are exceedingly variable and difficult, 
the females especially, to separate satisfactorily into species; the males, however, offer 
better differential characters in the extent of the emargination of the epistoma. 
These insects are mostly of large size, and some of the species are spotted or marked 
with red; in the male the epistoma is more or less deeply emarginate, the posterior 
femora in the same sex often swollen and flattened, and the head larger and broader 
than in the female. 
Many of the species are found in houses, and are nocturnal in their habits, and 
frequently attracted by light. 
1. Zophobas tridentatus. 
Zophobas tridentatus, Dej. Cat. 1837, p. 226; Kraatz, Deutsch. ent. Zeit. 1880, p. 124. 
Hab. Panama, David (Champion).—CotomBia ; GuIANA; BRAZIL. 
2. Zophobas pedestris. (Tab. V. fig. 16, 3.) 
Form of Z. tridentatus ; the epistoma in the male very broad in front, very distinctly tridentate (deeply 
emarginate on each side, the middle produced as far as the sides); the legs and antenne longer; the 
femora stouter and not so smooth; the tibise much longer, the anterior pair more distinctly curved, larger 
and longer. 
Length 30 millim. (¢.) 
Hab. Nicaraeua, Chontales (Belt). 
A single male from Nicaragua, differing as above, and probably distinct from Z. tré- 
dentatus. The antenne are drawn too short and the femora too thin in our figure. 
3, Zophobas klingelhofferi. 
Zophobas klingelhifferi, Kraatz, Deutsch. ent. Zeit. 1880, p. 126°. 
Hab. Mexico! (Klingenhéffer), Cordova (Sallé).
