408 INSECTA. 



Like the Lamellicornes of the ensuing section, the last Copro- 

 phagi have all their feet inserted equidistant from each other, and a 

 very distinct scutellum. The labial palpi are glabrous or but slightly 

 pilose, and their third and last joint is larger, or at least longer than 

 the preceding ones. The elytra completely envelope the contour of 

 the abdomen, or form an arched roof to it, a character which ap- 

 proximates them to the Scarabaeides of the following section. Inde- 

 pendently of this, these Insects, with respect to their antennae and' 

 legs, are closely allied to those of the preceding subgenus; but the 

 sexual variations are less strongly marked, and frequently consist of 

 mere tubercles. They are all small. Several species appear in the 

 very beginning of Spring. They form two subgenera. 



Aphodius, Illig. Fab. — Scarabasus, Lin. Geoff. — Copris, Oliv. 



In which the last joint of the palpi is cylindrical, and that of those 

 attached to the labium somewhat more slender than the preceding 

 ones, or at least not thicker. There is no appendage or corneous 

 and dentated lobe to the inner side of the maxillae. The body is 

 rarely short, with the abdomen arched, and when these characters 

 are present, the thorax is not transversely sulfated. 



A. Jimetarius; S. fcmetarkis, L.; Panz., Faun. Insect. Germ., 

 XXXI, 2. Three lines in length; black; elytra and a spot on 

 each side of the thorax fulvous; three tubercles on the head; 

 elytra with punctured striae(l). 



PSAMMODIUS, Gyll. 



Where the last joint of the palpi is oval and the thickest and 

 longest of the whole number, and in which the internal lobe of the 

 maxillse is corneous and bidentated. The body is short, the thorax 

 transversely sulcated, and the abdomen inflated(2). 



pantis, nemetrinus, nemestrinus, sabxus, Jachus, Sec, of Fabricius; the Ateuchus 

 Tmolus, Fischer, Entomog'. Russ., I, viii, 1, 2, is a Copris.

(2) The only one I refer to it is the Psammodius sulcicoUis, Gyll., Insect. Suec. 

 I, p. 9. The other species are true Aphodii. See Encyc. Method., article Psam- 

 modie. 



The genus Euparia, established in the Encyc. Method., by MM. Lepeletier 

 and Serville, belongs to this section, but as they have not completely described it, 

 and I have never seen the Insect on which it is founded, I cannot assign its place. 

 According to those gentlemen, the sides of the head are dilated and form a trian- 

 gle. The posterior angles of the thorax are emarginated, and the humeral angles 

 of the elytra are prolonged anteriorly into a point. The only species quoted is 

 the castanea. These characters, and even the colour, induce me to suspect that 

 this genus is closely allied to the Eurysterne of Dalman, which we have already 

 mentioned.
