204 MEMOIRS ON THE COLEOPTERA 



cated above, would seem to prove the generic weight of this char- 

 acter when compared with the single spicule of Ligyrus ruginasus 

 Lee., which is made the type of a separate genus below. In 

 tumulosus Burm., forming the next subgeneric group, these small 

 spiculiform processes are very much more widely separated and 

 this species is also peculiar in its elongate-oval form of body, larger 

 head and basally more thickened hind tarsi. The first species of 

 Ligyrus proper, described above under the name longulus, has also 

 an elongate-oval form of body and unusually large triangular basal 

 joint of the hind tarsi, the second joint normal however, but the 

 minute spicules of the clypeal apex are approximate as usual. 



The paper by LeConte on Bothynus (Journ. Ac. Phila., 2d ser., 

 I, p. 87) and the volume of Burmeister's work treating the same 

 subject, appeared almost simultaneously in 1847, so that neither 

 author could allude to the work of the other. Although LeConte's 

 description of Bothymis morio was modified somewhat, later on, 

 (Proc. Ac. Phila., 1856, p. 20), there can be no doubt that the 

 original description referred to the species described by Burmeister 

 at the same time as Podalgus variolosus and earlier, by DeGeer, as 

 Scarabtzus gibbosus. The LeContian morio is the female of gibbosus, 

 this sex being somewhat narrower and more elongate than the male, 

 as can be seen when large series are carefully segregated sexually. 

 That the Geotrupes juvencus, of Fabricius, refers to the same species, 

 cannot at least be disproved by evidence to the contrary, his de- 

 scription being valueless in making any refined distinctions. The 

 synonymy given under Ligyrus gibbosus in the Biologia by Mr. Bates 

 is therefore correct, except in regard to neglectus and obsoletus of 

 LeConte which are both specifically valid. The above description 

 of obsoletus is taken directly from the original, as I do not now have 

 examples of that species at hand. 



Group III. 

 Subgenus Anagrylius nov. 



So far as I am able to discover LeConte was in error in ascribing 

 a bidentate maxillary galea to Ligyrus gibbosus, though correct in 

 stating that it is tridentate in neglectus and ruginasus. As a matter 

 of fact it is tridentate in all the species of the restricted Ligyrus, 

 including gibbosus, but in the present group it seems to have only
