TERA PUS.—HOMALOPYGUS. 235 
TERAPUS. 
Terapus, Marseul, Monogr. in Ann. Soc. Ent. Fr. 1862, p. 680. 
This remarkable genus contains a single species from Mexico. According to recent 
observations it is of formicarious habits. | 
1. Terapus mniszechi. (Tab. VII. fig. 5.) 
Terapus mnizechi (sic), Mars. Monogr. in Ann. Soc. Ent. Fr. 1862, p. 682, t. 7. no. xlv. fig. 1’. 
Hab. Mexico (coll. Mniszech1, Flohr), Jalapa (Hoge). 
One example has recently been received from Herr Hoge. 
ONTHOPHILUS. 
Onthophilus, Leach, Zool. Miscell. i. p. 76 (1817). 
There are twenty species of this genus known at present—six from Europe, three 
from North America, three from Africa, seven from Asia, and one from Madagascar ; 
but this can only be a small proportion of those existing in nature. 
Most of its representatives are found in dung or decaying vegetable matter; the 
setose species from Asia and Africa occur under bark. 
1. Onthophilus flohri, sp. n. 
Ovatus, supra convexiusculus, niger, subopacus; antennis pedibusque piceis; fronte rugoso-punctata, antice 
triangulariter elevata, medio carinata; pronoto parum transverso, margine arcuato, elevato, dense et 
grosse strigoso, 6-costulato, costa externa brevi ceteris plus minusve abbreviatis; elytris 3-carinis validis, 
intervallis biseriatim punctatis ; propygidio undique grosse punctato, in medio carinato, utrinque tuber- 
culato; pygidio basi (minime profundo) bifoveolato, medio transversim et longitudinaliter elevato ; 
prosterno mesosternoque grosse punctatis. Long. 2} millim. 
Hab. Mexico, Durango (fohr). 
The distinctive characters of this species lie chiefly in the transverse thorax, the sides 
of which are evenly arched, in the short external thoracic coste, and in the almost 
perfect oval outline. It is probably most nearly allied to O. lecontei, Horn, which is 
only known to us from description ; but it also has some of the characters of O. striatus 
(Fabr.). From the latter it differs in the thoracic carinz and in the elytral costa, as 
well as in the sculpture of the propygidium and pygidium. The suture is very slightly 
elevated, and so also are the intermediate elytral striz; in these respects it resembles 
the European O. affinis, Redt. The mesosternum is very slightly sinuous anteriorly. 
A single example sent by Mr. Julius Flohr in 1887. 
HOMALOPYGUS.
