86 R. 08TEN SACKEN. 



The palplgerous piece of the labium (fig. 3) is a fleshy tubercle, 

 beset with bristles ; the mentum under it is not an independent piece, 

 and merely marked off by folds around it. The palpi are horny cones, 

 inserted upon scutiforni basal pieces ; their tip does not project much 

 above the fleshy labium upon which they are inserted. 



The thoracic segments are more glabrous than the others, being beset 

 on the upper side with transverse rows of sparse, soft hairs ; the third 

 segment, besides its row of hairs, has a row of minute spines. The 

 breast and pleurae also have some long, and rather soft hairs. The 

 first segment shows, above the spiraele, on each side, a pale yellow 

 region of indefinite outline, ending anteriorly in a reddish yellow spot; 

 this evidently is a rudiment of the horny plate which exists here in 

 other lamellicorn lai-vae. 



The fvet (fig. 4) are somewhat shorter than the rather large coxae, 

 they are beset with spine-like bristles, and end in a pencil of such 

 bristles, almost hiding the small unguis between them. The front 

 pair of feet is perceptibly smaller than the other two and has only 

 small coxae. All the feet are far apart at their bases. 



The abdomen, above, is densely beset with minute spines, rather 

 evenly distributed over seven dorsal segments and not quite reaching 

 the stigmata on both sides; the eighth segment is almost free from 

 them ; the ninth or last segment is beset with them on its posterior 

 part only, round the anul opening. A row of soft hairs runs acros? 

 each segment, from stigma to stigma. The venter has similar rows of 

 hairs, becoming very sparse on the last segments. 



The thoracic, as well as the abdominal segments, are divided by 

 deep furrows in transverse bolsters, the longest of which bears the 

 stigmata at its ends. The last abdominal segment is as long or a little 

 longer than the two preceding taken together and is divided in two 

 halves by a transverse furrow. The anal opening is j^-shaped. The 

 arrangement of the stigmata is the normal one. 



When I compare this larva with the analytical table of the lamelli- 

 corn larvae by Erichson, reproduced by Chapuis (Larves des col., p. 

 454), I find that it has the two separate maxillary lobes attributed to 

 the Scarabaeidae Laparosticti ; it has the segments divided by deep 

 furrows into transverse bolsters, like the subdivision A in tliut table 

 {Geotrupiilx, Aiiliodiidse, C'upridcP., Troijidse). When I further com- 

 pare our larva with the few existing descriptions of larvae of these 

 groups, T soon perceive that the choice will lie between the G'cofriipi<fpe 

 and Tioijidx. The Aphodiidx and CopridsearQ excluded by the struc-
