with white hair. Thorax tliickly covered with short wliite 

 pubescence, closely punctured ; the median segment closely 

 transversely striated, the strise strongest on the base ; the 

 furrow on the apical slope is wide and deep and extends to 

 shortly beyond the middle. The metasternal process is de- 

 pressed in the middle at the base; the sides have two keels ; 

 the middle has a narrow keel ; the apex is bluntly bilobate. 

 Legs black, except the hinder femora, which are red ; the 

 anterior calcaria and the base of the posterior are rufous ; 

 the tarsal spines are of a deeper rufous colour ; the legs are 

 covered thickly with a wliite down. Wings fusco-violaceous ; 

 the stigma and nervures black ; the two recurrent nervures 

 are received behind the middle of the cellule ; the upper 

 part of the second recurrent uervure is straight and oblique. 

 Aljdomen pruinose, shining; the pygidium haired only along 

 the sides ; the basal ventral segment is stoutly keeled 

 laterally; the hypopygium punctured. 



Odontolarka, gen. nov. 



Clypeus with three lateral, two central, and one inter- 

 mediate teeth on tlie apex ; it is broader than long, roundly 

 convex in the middle. Mandibles large, narrowed, and with 

 only one tooth on the apex ; on the lower side, near the base, 

 is a large rounded tooth. Antennce placed low down, oppo- 

 site the lower edge of the eyes. Eyes large, almost parallel 

 on the inner side; they reach almost to the base of the 

 mandibles; the three ocelli are distinct and are placed in a 

 triangle ; the ocellar region is slightly raised ; the front has 

 a shallow furrow. Occiput margined. Pronotum large, 

 tuberculate in the middle behind ; its apex not reaching to 

 the level of the mesonotura ; its middle deeply depressed. 

 Mesonotum furrowed down the middle; the tubercles are 

 large. Mesosternum furrowed down the middle, and with a 

 transverse furrow in front of the middle coxfe. Median 

 segment longer than broad. Legs stout ; the tibiae and tarsi 

 spinose ; the claws simple. Wings appendiculate at the 

 apex ; there are three cubital cellules, the second and third 

 of almost equal length ; the transverse basal nervure is inter- 

 stitial. The basal segment of the abdomen is triangular ; the 

 second segment is the longest ; the pygidium opaque and 

 finely transversely striated. 



Comes nearest to Parapiagetia : may be known from it 

 readily by the large number of teeth on the apex of tlie 

 clypeus; Kohl's genus has only four. The distinct ocelli, 

 the vertex without any raised folds as in Larra &c., and the
