 Palpi maxillares articulo ultimo ovah. Tibiae anticse extus excavatae. 



I have only a single specimen of the species described below ; but, 

 so far as I have been able to examine it, it seems to differ from 

 Morychiis in the six-jointed very narfow club of the antennae. It is 

 apparently perfectly free from any villosity ; but under a strong lens 

 very short erect hair-like bristles are seen to exist.

Organs of the mouth and eyes entirely concealed during the retraction 

 of the head. Mentum broad, strongly narrowed anteriorly. Ligula 

 coriaceous, dilated in front, with slightly prominent angles and rounded 

 in the middle. Lobes of the jaws horny, external obliquely shortened at 

 the end, and terminated by a small tooth ; the internal sometimes 

 furnished with fine hairs. Mandibles short, wide, slit at the end, each 

 division bifid, furnished inwardly with a membraneous margin. Labial 

 palpi short, their two first joints small, third oval, obtuse at the extre- 

 mity ; the last of the maxillary ovate and acuminate. Labrum large, 

 rounded in front, a little angular at the sides. First joint of the antenncB 

 oval, rather stout ; joints two to seven sub-cylindrical, eight to ten 

 forming gradually a feeble elongate club. Legs received into not very 

 deep excavations, tibicB moderately wide, all the tarsi free, simple, 

 cihated underneath.
