KHOINA, n. gen. 

 Buccal organs of Lepitrix, the lobes of the ligula are also long, 

 but broader and spatulate, the anterior tibiae have no trace of a third 

 basal tooth, but the shape of the clypeus is very different being 

 declivous, rounded in front, and with the margins highly raised all 

 round ; the hind tarsi are long, and the joints are clothed with very 

 long feathery hairs in one species, but not in the other, the whole 

 propygidiuni is left uncovered by the elytra ; the anterior tibiae are 

 bi-dentate, and have an inner spur. 



Key to the Species. 



Black, with the elytra piceous-brown in the discoidal part ; pro- 

 thorax with an anterior and a posterior band of squamulose hairs ; 

 elytra with a few scattered white scales, pygidium non-scaly but edged 

 along the base of the propygidiuni and also along the abdominal 

 segment with white appressed hairs ; posterior tarsi simple . . . . hi-lnteralii'.

Black, with the elytra chestnut-brown, or fuscous, and piceous-red 

 in the central part of the disk ; head and prothorax clothed with long 

 villose greyish and flavescent hairs, and shorter appressed fulvescent 

 or whitish hairs along the anterior and posterior margins, in the 

 female these hairs are replaced by scales ; scutellum clothed with 

 appressed hairs ; elytra very much narrowed laterally from the 

 ampliated humeral part, deeply punctured, clothed with seriate, black 

 and greyish hairs, and having a narrow, marginal band of whitish 

 scales ascending also along the suture to about the median part, as 

 well as a few elongate whitish scales scattered here and there on 

 each side of the suture, and sometimes fairly numerous but not 

 closely set ; propygidium and pygidium deeply and closely punc- 

 tured, clothed with long, villose black, or black and grey hairs, but 

 with the apical margin of the propygidium fringed with appressed 

 white hairs ; the abdominal segments have a narrow fringe of similar 

 hairs, and the pectus is clothed with long, dense, greyish or whitish 

 villose ones ; the head and clypeus are closely and deeply punctured, 

 the latter is strongly declivous, very sharply and highly marginate
