The species for which I propose this new generic name has the 

 appearance of a Colpochila, — though very much smaller than any 

 Colpochila known to me, — but is at once distinguishable from 

 the species of allied genera by the sides of its clypeus not cutting 

 into the eye. I find however a faintly marked smooth but 

 scarcely elevated line on the eye occupying the position that in 

 allied genera is occupied by the canthus-like prolongation of the 

 clypeus. Another notable character consists in the long closely 

 placed pilosity on the underside of the hind and intermediate 

 tarsi in the male which gives those organs an appearance from a 

 certain point of view suggestive of a feather. In the female the 

 hind tarsi are glabrous except at the apex of each joint. The 

 mentum, moreover, is remarkable on account of the very deep 

 triangular excision (reaching nearly half-way to the base) of its 

 apical margin.

GLOSSOCHEILIFER (gen. nov. Sericoidarum). 



Mentum antice latum fortiter emarginatum ; palpi fere ut 

 Diphyllocerce (labialibus modicis articulo ultimo sat elon- 

 gato apicem versus angustato, maxillaribus sat elongatis 

 articulo ultimo quam prsecedens sat longiori) ; labrum for- 

 titer productum, ad apicem angustatum et reflexum ; oculi sat 

 magni, sat nitidi, fere Iseves, antice a cantho profunde incisi ; 

 antennae (speciei typicse) 9-articulat8e, clava 3-articulata hac 

 maris articulis antennarum 2-6 conjunctis sequilonga, feminse 

 sat breviori ; prothorax transversus ; elytra geminato-striata; 

 tibiae anticse extus S-dentatse, posticis minus elongatis (parte 

 apicali sat fortiter dilatata) ; unguiculi simplices ; sterna 

 pilis elongatis dense vestita; tarsis maris quam feminse 

 multo longioribus robustioribus. 

 This genus differs from all its allies in the remarkable form of 

 its labrum, which is very large and projects forward from the 

 lower extremity of the front (subvertical) face of the clypeus,
