 side, curving inward to the middle. Segment 7 of abdomen only slightly shorter than 6 ; 

 segment 8 about two-thirds as long as 7, and as long as 9 and 10 together ; 10 rather 

 longer than 9, and widely concave at the extremity above. Legs short and thick, 

 slightly compressed ; all the femora lobate-dentate at the extremity beneath on each 

 carina, and the base of the tibiae furnished with a centi-al lobe beneath, which fits in 

 between the femoral lobes ; first joint of the front tarsi strongly lobate above; middle and 

 hind femora with the grey dusting forming a broad band towards the extremity ;

DiXIPPUS (?) INSTJLARIS, Sp. n. 



Female. Cylindical. Brown, granulated, head with a low transverse crest on the 

 vertex, between the eyes, curving downward and inward at the ends ; a row of raised 

 warts, larger than the others, before the extremity of the head. Scape of the antennae 

 very broad and flattened, broadest in the middle, and about half as long again as broad ; 

 down the middle of the body runs a low median carina, except on the prothorax, which 

 is marked with a shallow cross-shaped depression. Pront femora beneath with a central 

 ridge, and a pair of outer carinae, closely api^roximating, at the sides, the outermost 

 denticulated towards the extremity, and the innermost serrulated throughout its length. 

 The front tibiae are greatly compressed, and the upper ridge is slightly waved and at the 

 extremity it projects obtusely forward. The first joint of the front tarsi has a flattened 

 foliaceous ridge above, Avhich raises it to the height of the tibite; it is nearly as long as 

 the remaining joints together. The four hinder femora are slightly denticulated at the 

 extremity beneath ; and their tibiae are slightly lobate near the base beneath, and are 

 also slightly thickened towards the extremity. The median segment is rather long
